Description
Technical Field
The invention relates to the technical field of fabrics, and particularly relates to an antibacterial and deinsectization fabric and a preparation method thereof.
Background
With the continuous improvement of living requirements of people, more and more household articles pay more attention to comfort degree and sanitation degree on the basis of beauty; the fabric is an indispensable part in daily home furnishing, no matter the daily clothes, towels or the like, or carpets, curtains, bedsheets or the like can not be used, after the articles are used for a long time, a large amount of bacteria or microorganisms can be bred on the surface of the fabric, so that the health of a user is influenced, and the use and the attractiveness are influenced; in recent years, the situation that mite larvae damage fiber products such as fabrics is increasing, and the problem that mites inhabiting the fabrics and other articles cause allergic diseases is also increasing; because the prior art is not enough, after washing, the medicine portion can flow along with water for ordinary surface fabric that has antibiotic anti-mite medicine, thereby flows along the gap of surface fabric, thereby causes the property of a medicine that the surface fabric contains to disappear, and then influences the effect that the surface fabric was antibiotic anti-mite once more, and the sweat that flows out when the user sleeps also can take away some medicine simultaneously, causes the antibiotic anti-mite effect of this kind of surface fabric to be low.
Some technical schemes related to a preparation method of an antibacterial and anti-mite fabric also appear in the prior art, for example, a Chinese patent with the application number of CN201910539847.X discloses a preparation method of an antibacterial and anti-mite fabric, which comprises the steps of mixing wormwood fibers, mint fibers, coconut fibers, sisal fibers, bamboo fibers and rosemary fibers together by an impurity removal mixer to prepare fiber strips; then the prepared fiber strips are processed in a series of ways to prepare fiber yarns, and finally the fiber yarns and textile yarns are prepared into fabrics; according to the technical scheme, wormwood fiber, mint fiber, coconut fiber, sisal fiber, bamboo fiber and rosemary fiber are mixed together through an impurity removal mixer to prepare fiber strips serving as raw materials for preparing the antibacterial and anti-mite fabric, so that the antibacterial and anti-mite effects of the fabric are improved; however, in the technical scheme, the antibacterial and anti-mite substances in the component fibers in the fabric flow out along the gaps between the fabrics through water flow after being kneaded in the cleaning process, so that the antibacterial and anti-mite medicinal components of the fabric in the technical scheme are lost, the antibacterial and anti-mite effects of the fabric after being cleaned in the technical scheme are affected, and the limitation of the scheme is further caused.
Disclosure of Invention
The invention aims to provide an antibacterial and deinsectization fabric and a preparation method thereof, and the P of the organic quaternary phosphonium salt molecule prepared by the invention + Compared with the common quaternary ammonium salt antibacterial agent, the polarization effect and the electropositivity of the antibacterial agent are stronger, the antibacterial activity is higher, and meanwhile, the antibacterial agent also has good insect resistance. Wherein, one end of the organic quaternary phosphonium salt molecule is a double bond structure, and can be connected with the polypropylene polymer chain through a grafting reaction, so that the long-acting antibacterial and deinsectization effect can be achieved, the prepared antibacterial and deinsectization fabric has excellent antibacterial and deinsectization effects, and the antibacterial and deinsectization effect can reach more than half a yearHas wide application prospect.
The technical scheme of the invention is realized as follows:
the invention provides an antibacterial and deinsectization fabric which is prepared from antibacterial and deinsectization polypropylene, wherein the antibacterial and deinsectization polypropylene is prepared by polymerizing polypropylene and organic phosphine molecules, and the chemical structural formula of the antibacterial and deinsectization polypropylene is shown as a formula I:
n＝100-500。
as a further improvement of the invention, the chemical structural formula of the organic phosphine molecule is shown as formula II:
as a further improvement of the invention, the preparation method of the organic phosphine molecule comprises the following steps:
s1, reacting chloro-tert-butane, magnesium and an initiator, adding diethyl phosphonite, and reacting to obtain an intermediate A, wherein the structure is as follows:
s2, reacting the intermediate A with a reducing agent to obtain an intermediate B, wherein the structure is as follows:
s3, reacting the intermediate B with n-butyllithium, adding methacryloyl chloride for reaction, and filtering to obtain an intermediate C, wherein the structure is as follows:
s4, adding the intermediate C into dilute hydrochloric acid, soaking for reaction, filtering, and drying to obtain the organic phosphine molecules.
As a further refinement of the invention, the initiator is iodine; the reducing agent is lithium aluminum hydride or sodium borohydride.
As a further improvement of the present invention, the ratio of the amounts of said substances of chloro-tert-butane, magnesium, diethyl phosphinate in step S1 is 1: 1: (0.3-0.4).
As a further improvement of the present invention, the ratio of the amounts of the intermediate a and the reducing agent in step S2 is 1: (1-1.2).
As a further improvement of the present invention, the ratio of the amounts of the intermediate B, n-butyllithium, and methacryloyl chloride in step S3 is 1: (1-1.2): 1.
