Water-borne epoxy resin and super-amphiphobic coat as well as preparation method and application of water-borne epoxy resin and super-amphiphobic coat

Abstract

The invention belongs to the field of super-amphiphobic materials and discloses water-borne epoxy resin and a super-amphiphobic coat as well as a preparation method and application of the water-borne epoxy resin and the super-amphiphobic coat. The water-borne epoxy resin is a polymer with the structural formula of P (A-r-B) and is obtained through the polymerization reaction of a water-soluble monomer A and a monomer B, wherein the mass ratio of A and B is 1: (0.2-20), and the tail end of the monomer B is an epoxy group. The obtained water-borne epoxy resin is dissolved into solvent, then a fluorine-containing substance, particles and a catalyst are added to the solvent to obtain a mixed solution; the mixed solution is stirred for reaction, and distilled water is dropwise added to form a water solution; a base material is soaked in the water solution, or the water solution is sprayed on the surface of the base material, and the super-amphiphobic coat is formed on the surface of the base material after drying treatment. The super-amphiphobic coat is simple to construct and has excellent lyophobic and oleophobic properties and excellent durability.

AI Technical Summary

Problems solved by technology

Although the performance of super-amphiphobic materials mentioned in international published articles and patents is very excellent, however, there are no industrialized products in related fields, mainly because some basic problems have not been solved: (1) the super-amphiphobic surface Problems with construction methods: Most methods have problems such as harsh conditions, cumbersome steps, and high cost, such as the template method, which requires special equipment to cooperate

(2) The universality of superamphiphobic surface construction: the methods reported in the literature are all formed by special treatment for a special surface, so the application range is narrow

Unable to find a universal method that can be applied to various surface treatments

In addition, even if there is a universal treatment method, there will be problems of poor adhesion between the coating and the surface

(3) Environmental pollution problems: when most fluorine-containing components are used to prepare super-amphiphobic surfaces, fluorine-containing solvents are usually used

Fluorine-containing solvents will cause great pollution to the environment, so the environmental pollution problems incidental to the preparation process must be considered

(4) Problems in practical application: firstly, the overall lack of applied research, especially the slight lag in theoretical research in applied research, hinders the progress of applied research

[0010] However, the above-mentioned amphiphilic fluoropolymers are all block polymers prepared by controllable active polymers. Relatively speaking, the synthesis cost of block polymers is relatively high, and the process is very complicated, so it is not suitable for large-scale industries. change
