Description
Technical Field
The invention relates to the field of cleaning agents, and in particular relates to an anionic-cationic surfactant compound cleaning agent for cleaning hard surfaces and a preparation method thereof.
Background
The foam cleaning agent is mainly used for removing oil stains, fats, proteins, polysaccharides, inorganic salt deposits and other stains which are difficult to remove by water on hard surfaces by generating abundant foam and surface activity through a surfactant. The foam imparted by the surfactant selectively adsorbs soils, particularly solid soil particles, to reduce the degree of soiling of the wash liquor, and thus facilitate washing. The surfactant in the foam liquid film forms a mixed adsorption molecular layer with a hydrophilic group facing inwards and a hydrophobic group facing outwards in water, and when the foam is contacted with the organic dust, the hydrophobic group of the foam liquid film is easier to adsorb the organic dust than water molecules. In addition, the foam has a liquid carrying capacity, and the longer the foam on a hard surface is, the longer the action time of the cleaning agent on dirt is, and the better the effect is. Thus, the better the foam stability and the better the cleaning effect. The common surfactants for the current foam cleaning agent are mainly divided into the following types:
(1) a cleaning agent containing a single type of anionic or cationic or nonionic or zwitterionic surfactant, such as a low-temperature foam cleaning agent for meat processing places disclosed in publication No. CN113174296A and a preparation method thereof, wherein the adopted surfactant is a nonionic surfactant or a cationic surfactant, but the invention has high use concentration and unstable foam;
(2) foam cleaners composed of anionic-nonionic surfactants;
(3) a foam cleaning agent consisting of a cationic-nonionic surfactant;
(4) a combination of nonionic-zwitterionic surfactants, such as disclosed in publication No. CN106590960A, an alkaline foam cleaner for cleaning food soils, wherein a combination of amine oxide and glycoside nonionic surfactants is mainly used, but the invention uses a high concentration (2% -4%) to achieve enhanced foam stability by raising the viscosity of the cleaning solution, which is lowered at elevated temperatures, resulting in decreased foam stability, and high viscosity is not conducive to foam spraying, causing inconvenience in use;
(5) a combination of anion-zwitterion surfactant, such as a high-efficiency foam cleaning disinfectant special for farms disclosed in the publication No. CN112961739A, wherein an anion surfactant alpha-sodium alkenyl sulfonate and a zwitterion surfactant AOS surfactant are adopted; or the publication No. CN110079402B discloses an environment-friendly composite alkaline foam cleaning agent and a preparation method thereof, wherein the cleaning agent is obtained by mixing an anionic surfactant and a zwitterionic surfactant betaine or fatty amide propyl amine oxide.
The surfactant combinations adopted in the existing cleaning agent are mainly more than 5, and the problems of high surfactant addition amount, high use concentration, poor wettability and poor foam stability exist. Publication No. CN111440676A discloses a foam cleaning agent with disinfection and cleaning functions and a preparation method thereof, and the technical scheme is that a cationic surfactant, an anionic surfactant, a nonionic surfactant, a solubilizer, a chelating agent, an antirust agent, a pH regulator and micromolecular alcohol are compounded, so that the technical problems of corrosion of caustic soda to equipment and improvement of the disinfection function are solved, but the technical problem of poor foam stability in the foam cleaning agent is still not solved.
Publication No. CN1250470A discloses a hard surface cleaning composition comprising 1-30% by weight of a nonionic surfactant, 0.005-5% by weight of a water-soluble anionic polymer, and 0.005-5% by weight of a cationic surfactant, wherein the anionic polymer is mainly polyacrylic acid polymer, and the cationic surfactant has a general formula of R 1 R 2 R 3 R 4 N + X - The technical principle is that the detergent is deposited on a hard surface through anion-cation interaction, so that a surface active system is formed on the hard surface, and the purposes of decontamination and anti-re-adhesion are achieved. However, in this solution, the polyacrylic acid polymer is only a polymer, and does not have high surface activity, that is, the polyacrylic acid polymer is not an anionic surfactant, and the polymer is usually used as a soil dispersant and an anti-redeposition agent when added into a cleaning agent. The essence of this solution is therefore also a combination of cationic-nonionic surfactants.
Publication No. CN109475125A discloses an activated antimicrobial combination of a quaternary ammonium compound of less than C20 chain length and an anionic carboxylate surfactant having a C6-C10 chain length, the combination having a molar ratio of the quaternary ammonium compound to the anionic surfactant of 10 or about 1. The technical proposal uses the anion-cation combination in the disinfection, and enhances the dynamic surface tension and the wettability, thereby having the functions of synergy and enhancing the surface activity and the disinfection efficacy.
In summary, the existing foam cleaning agent mainly adopts anions, cations or anions/cations/non-ions, and has the problems of high addition amount of surfactant, high use concentration and poor foam stability.
According to the invention, the combination of the anionic/cationic surfactants is applied to the foam cleaning agent, and the strong electrostatic interaction between anions and cations is utilized to generate high surface activity, reduce the surface tension and the lowest use concentration and improve the wettability and the foam stability, so that the problems of high addition amount of the surfactants, high use concentration, poor wettability and poor foam stability are solved.

Wherein the pH regulator is mainly used for regulating the pH value of the solution to the range of 1-13.
Further, the molar ratio of the anionic surfactant to the cationic surfactant is 1.
Further, the anionic surfactant is one or more of sodium dodecyl sulfate, sodium dodecyl benzene sulfonate, sodium alpha-alkenyl sulfonate, sodium lauryl alcohol ether sulfate and sodium dioctyl sulfosuccinate.

Further, the washing assistant is one or more of sodium citrate, sodium metasilicate, sodium epoxy succinate, urea, sodium polyacrylate and the like.
Further, the solubilizer is sodium p-toluenesulfonate or sodium cumenesulfonate.
Further, the solvent is propylene glycol methyl ether or diethylene glycol butyl ether.
The invention also discloses a preparation method of the anion-cation surfactant compound cleaning agent, which comprises the following steps:
(1) Sequentially adding an anionic surfactant and a cationic surfactant into water, and stirring until the anionic surfactant and the cationic surfactant are completely dissolved;
(2) And (2) adding the hard water resisting agent, the washing assistant, the solubilizer and the solvent into the solution obtained in the step (1), and fully mixing and homogenizing.
(3) And dissolving the pH regulator in water, and regulating to obtain the pH value required by the final cleaning agent to obtain the foam cleaning agent.
And (2) after the anionic surfactant is completely dissolved in the step (1), slowly adding the cationic surfactant, and slowly adding and stirring the cationic surfactant in the adding process.
According to the invention, an anionic-cationic surfactant system is adopted, and strong electrostatic interaction is realized between an anionic surfactant and a cationic surfactant, the electrostatic interaction can avoid reaction and activity loss through the selection and the proportion of a specific surfactant, and a synergistic effect is generated, so that the cationic-anionic surfactant has incomparable high surface activity compared with a single surfactant, and the CMC and the surface tension can be greatly reduced. Because the surface performance of the surfactant can directly influence the performance of the foam, the surface tension can be reduced by compounding the surfactant, so that the radius of bubbles is reduced, the liquid drainage speed is reduced, and the foam is more stable. Besides stable foam performance, the anion and cation surfactant compound system also has excellent wetting performance and emulsifying performance, and is used for cleaning hard surfaces, and the foam stability is good, the wetting speed is high, the emulsifying performance on grease is good, and the cleaning effect is better. Meanwhile, due to the dual functions of the stability and the wettability of the foam, the use concentration of the cleaning agent can be obviously reduced, so that the cleaning agent can achieve the same or even better cleaning efficiency under the condition of lower concentration or less use amount.
In the invention, the cationic surfactant didodecyldimethylammonium chloride and ditetradecyldimethylammonium chloride have the double performances of the dialkyl monoquaternary ammonium salt and the monoalkyl diquaternary ammonium salt surfactant, and have strong performances of emulsification, adsorption, hydrophobicity, corrosion resistance, sterilization and the like. The biquaternary ammonium salt has excellent water solubility and good bactericidal performance, can inhibit bacteria from generating drug resistance, can achieve the cleaning and bactericidal effect with lower content, and reduces the use cost. Meanwhile, the cationic surfactant has an anti-corrosion effect, cannot corrode equipment, and greatly widens the application range of the cleaning agent.
In the invention, didodecyldimethylhydroxypropyldiammonium chloride, also known as N-dodecyldiquaternary ammonium salt, is an N-alkyl diquaternary ammonium salt type cationic surfactant. In the prior art, the bactericidal property, emulsifying property and caking property of N-dodecyl biquaternary ammonium salt are generally utilized, such as bactericidal property, so that the N-dodecyl biquaternary ammonium salt is applied to the fields of deodorizers, bactericides and the like; the emulsifying property and the bonding property enable the coating to be widely applied to the fields of coatings, plastics, rubber and the like; the adsorption property makes the ore dressing widely used. The N-dodecyl biquaternary ammonium salt contains a didodecyl hydrophobic group, hydrophilic hydroxyl and a biquaternary ammonium salt, wherein the contained biquaternary ammonium salt positive charges can not lose surface activity because a large number of positive charges carried by cations exist in the cleaning agent by controlling the ratio of the cationic surfactant to the anionic surfactant. And the surfactant is mixed with a specific sodium sulfate salt type anionic surfactant, even if the surfactant and the specific sodium sulfate salt type anionic surfactant are combined, the molecular bond energy and the surface activity cannot be influenced, the respective activity of the anionic/cationic surfactant is reserved, the anionic/cationic surfactant is arranged more tightly at an interface, so that the solvent and foam are stabilized, the surface tension reducing capability is stronger, and the using amount is less.

Evaluation of Performance
1. Foaming stability test
The foaming performance of the foam cleaning agent was tested by the Ross-mile method at a concentration of 0.25% and a temperature of 45 ℃ and the test data are shown in tables 1 and 2:
TABLE 1 determination of foam Properties of acidic foam cleaners
For acidic foam cleaning agents, examples 1-7 adopt an anion/cation compound system, the 30min foam reduction rate is lower, and the foam stability is better. Comparative example 1, using a monoanionic surfactant system, foam stability was poor although the initial foam height was high; the cation surfactant system is used alone, so that the foam height is low and the foam stability is poor; the use of anionic/nonionic surfactant or cationic/nonionic surfactant systems can improve foam height and foam stability to some extent.
TABLE 2 foam Performance test results for alkaline foam cleaners
For the alkaline foam cleaning agent, the anionic/cationic compound system is adopted in examples 8-13, the foam reduction rate is lower in 30min, and the foam stability is better.
As is clear from tables 1 and 2, the foams of the acidic foam cleaning agent and the alkaline foam cleaning agent of the present invention are more stable.
2. Determination of surface tension and detergency
The surface tension of the cleaning solutions of examples 6, 13 and comparative examples 1 to 9 was measured by adjusting the concentrations of the cleaning solutions to 0.5% at 25 ℃ using examples 6 and 13 as samples.
A blank control with increased detergency, 0.085% sulfuric acid and 0.05% sodium hydroxide as references;
refer to "QBT 4313-2012 acidic cleaning agent for food service tools and industrial equipment" acidic foam cleaning agent detergency;
refer to QBT 4314-2012 alkaline cleaners for food tools and industrial equipment for detergency of alkaline foam cleaners.
The results obtained are shown in table 3:
table 3 surface tension and detergency test results
As can be seen from table 3, the acidic foam cleaning agent and the alkaline foam cleaning agent of the present invention have low surface tension and high detergency effect. The surface tension of 0.085 percent of sulfuric acid and 0.05 percent of sodium hydroxide is high, and the decontamination effect is the worst; the single anionic surfactant system (comparative example 2) has greater detergency than the single cationic surfactant system (comparative example 3); the nonionic surfactant can improve the decontamination effect of a single surfactant system.
3. Sterilization Performance test
Taking the example 6 and the example 13 as samples, adjusting the concentrations of the cleaning solutions of the example 6, the example 13 and the comparative examples 1 to 9 to be 0.5 percent at the temperature of 25 ℃, and taking escherichia coli, staphylococcus aureus and candida albicans as test targets to test the sterilization effect, wherein the obtained data are shown in table 4;
TABLE 4 bactericidal Property test results
The sulfuric acid has a certain sterilization effect, and the sterilization effect is remarkably improved after the cationic surfactant (comparative example 2) is added. Alkali also has a bactericidal effect, and the bactericidal effect is reduced when the cleaning assistant such as alkali is removed (comparative example 9). The anion/cation compound surfactant is added into the acid or the alkali, so that the sterilization effect of the product can be improved.
4. Contact Angle testing
Important parameters of the liquid on the surface wettability of the material are that the contact angle of 0.5% diluent on a smooth stainless steel sheet is tested by adopting a dataphysics video optical contact angle measuring instrument OCA15EC, and the obtained test results are shown in figures 1 to 11.
As can be seen from FIGS. 1 to 11, the cleaning agent of the anion-cation surfactant system has smaller contact angle and better wettability than a pure nonionic-cation system and a nonionic-anion system, can quickly reach a hard surface, improves the cleaning efficiency, and has no dead angle in cleaning.
