Description
Technical Field

With the continuous development of wireless communication technology, the functions of base station equipment in a wireless communication system are more and more powerful, the complexity and the integration level of the base station equipment are higher and higher, and the application environment and the use scene are worse and worse. The communication iron tower is in an outdoor environment for a long time, and is often subjected to wind, rain and various corrosion, so that the service life is short. In order to prolong the service life of the communication iron tower, an anti-corrosion coating is usually coated on the surface of the communication iron tower to isolate a corrosive medium from a metal matrix, so that the damage of the external environment to the communication iron tower is reduced. However, most of the existing anticorrosive coatings belong to oily coatings, and the paint contains toxic solvents, so that the paint can pollute the environment and can also harm the health of construction personnel.
The fluorocarbon coating is a coating taking fluororesin as a main film forming substance; also known as fluorocarbon paint, fluorine resin paint, etc. Among various coatings, the fluororesin coating has various particularly excellent performances such as weather resistance, heat resistance, low temperature resistance and chemical resistance, and has unique non-adhesiveness and low friction because of the introduced fluorine element has large electronegativity and strong carbon-fluorine bond energy. Through the rapid development of decades, fluorine coatings are widely applied in various fields of buildings, chemical industry, electrical and electronic industry, mechanical industry, aerospace industry and household articles. The fluorocarbon coating becomes a coating brand with the highest comprehensive performance after high-performance coatings such as acrylic coating, polyurethane coating, organic silicon coating and the like. But the fluorocarbon resin is expensive, so that the application range of the fluorocarbon coating is greatly limited.
Disclosure of Invention
The invention aims to provide a water-based fluorocarbon coating for a communication iron tower and a preparation method thereof. The prepared coating has excellent water resistance, salt spray resistance, weather resistance and physical and mechanical properties, and can effectively prolong the service life of the iron tower when being used on the iron tower.
The technical scheme adopted by the invention is as follows:
a water-based fluorocarbon coating for communication iron towers is prepared from the following raw materials in parts by weight:
25-35 parts of waterborne fluorocarbon resin, 8-16 parts of hydrophilic graphene dispersion liquid, 15-25 parts of hydroxyl acrylic resin, 0.5-1 part of alcohol ester dodecamethylene, 5-8 parts of alkyd resin, 5-8 parts of waterborne polyurethane, 0.5-1.5 parts of environment-friendly waterborne flash rust inhibitor, 5-10 parts of superfine wollastonite powder, 5-10 parts of modified nano calcium carbonate and 5-15 parts of deionized water.
The hydrophilic graphene dispersion liquid is obtained by adding monochloroacetic acid into graphene oxide for acyl chlorination, adding hexadecyl trimethyl ammonium bromide for amidation and finally emulsifying.

Compared with other resins, the fluorocarbon resin has better heat resistance, chemical resistance, cold resistance, low-temperature flexibility, weather resistance and electrical property, and simultaneously, because the fluorocarbon resin has good crystallinity, the fluorocarbon resin also has non-adhesiveness and non-wettability, the antifouling property and the oil resistance of the coating can be improved. In the aqueous fluorocarbon resin, the F atom replaces the C atom and surrounds the carbon chain to form a tight protective layer, so that the aqueous fluorocarbon resin is not easy to be attacked by the outside, can be dispersed in water, does not need to be dissolved by adding a toxic organic solvent during use, is more environment-friendly, and still maintains the good performance of the fluorocarbon resin. The acrylate resin has excellent light resistance, heat resistance and weather resistance, better acid-base salt corrosion resistance, excellent flexibility and the like; the hydroxyl acrylic resin has good compatibility with waterborne fluorocarbon resin, alkyd resin and waterborne polyurethane, and can effectively improve the flexibility of the coating. The polyurethane has excellent low temperature resistance, chemical solvent resistance, wear resistance, adhesion, light aging resistance and the like. The alkyd resin molecule contains ester group, hydroxyl, carboxyl and unsaturated double bond, so that the alkyd resin can react with various functional monomers and resins, can generate chemical bond connection with waterborne fluorocarbon resin, hydroxyl acrylic resin and waterborne polyurethane, and connects various resins together to form a net structure, thereby improving the strength of the coating. The alcohol ester dodeca is used as a film forming additive, has very good hydrolytic stability, can effectively coalesce emulsion particles and reduce the film forming temperature, can effectively promote the crosslinking action of 4 film forming agents of waterborne fluorocarbon resin, hydroxyl acrylic resin, alkyd resin and waterborne polyurethane by adding the alcohol ester dodeca, and can fully play the roles of wetting, dispersing and inhibiting foam by adding the alcohol ester dodeca twice.
The graphene is a two-dimensional nanosheet layered nanomaterial, the crystal lattice in the two-dimensional crystal structure of the graphene is a hexagon formed by six carbon atoms, the thickness of the graphene is only one atomic layer, namely the thickness of the graphene is only one twenty ten-thousandth of that of one hair, and meanwhile, the theoretical specific surface area of the graphene is up to 2630m2The coating can be alternately and randomly arranged in the coating, so that the aim of effectively prolonging the diffusion path of a corrosive medium and effectively enhancing the physical shielding property of the coating is fulfilled; in addition, the fracture strength of the graphene is up to 125GPa, which is 200 times of that of steel, and the graphene also has very stable chemical properties, has very good resistance to water, oxygen and corrosive agents, and is an excellent anticorrosive material. By using the hydrophilic graphene dispersion liquid, the compatibility of graphene and a resin matrix is good, and the heat dissipation and corrosion prevention effects of graphene in a coating system can be more effectively exerted; the graphene is introduced into the coating, the excellent heat dissipation function of the coating system is endowed by the good heat conductivity of the graphene, and the excellent corrosion resistance of the coating system is endowed by the flaky large surface structure and the electric conductivity of the graphene.
The superfine wollastonite powder has good reinforcing property, can improve the toughness, durability, washing resistance and weathering resistance of the coating, can keep the surface of the coating smooth and good glossiness, reduces the oil absorption of the coating, keeps alkalinity and has corrosion resistance. The superfine wollastonite powder has good coverage rate and adhesion, can obtain high-quality bright-color coating, has good uniform coating property and ageing resistance, and can ensure that the coating has better mechanical strength, increased durability, enhanced adhesion and corrosion resistance by adding the superfine wollastonite powder into the coating.
The modified nano calcium carbonate particles have the advantages of hydrophile and oleophyle in the water-based paint, good dispersibility, no agglomeration and good binding property with the base material, can effectively improve the rheological property of the paint, improve the water resistance and the scrubbing resistance of the paint, and reduce the cost of the paint. The environment-friendly water-based flash rust inhibitor is prepared by compounding various high-performance corrosion inhibitors, does not contain toxic metal elements, can prevent the formation of water-soluble paint 'flash rust', can solve the problem of rust return when the paint film is dried and meets water, and improves the antirust performance and salt mist resistant effect of the paint film. The anti-flash rust agents HTK-001 and HTK-202 have good compatibility with coating and can be firmly adsorbed on a base material in a short time to form a layer of protective film.
The paint of the invention selects nontoxic or slightly toxic raw materials, and takes water as a dispersion medium, thereby effectively avoiding the pollution of toxic solvent in the oily paint to the environment, and simultaneously causing no harm to the health of constructors.
