Problems solved by technology

[0003] Existing water-based coatings do not have excellent super-weather resistance, high tensile strength and good flexibility. They have a limited range of application, do not have excellent mechanical properties, have high cost, low yield, and serious environmental pollution. Therefore, we proposed a fluorosilicone super weather-resistant water-in-water coating to solve the above problems

Abstract

The invention discloses a fluorosilicone super-weatherability water-in-water coating, made from, by weight, 45-70 parts of fluorosilicone emulsion, 20-30 parts of silicate solution, 15-25 parts of polyacrylates, 15-25 parts of isocyanates, 10-20 parts of polyether, 10-20 parts of sodium methyl silicate, 12-18 parts of titanium dioxide, 11-14 parts of sodium carbonate, 10-15 parts of zeolite powder, 10-15 parts of mica powder, 8-12 parts of sodium tripolyphosphate, 7-11 parts of sodium polyacrylate, 6-10 parts of tricresyl phosphate, 3-7 parts of ethylene glycol, 20-30 parts of deionized water,by: S1, adding the fluorosilicone emulsion, silicate solution, polyacrylates, isocyanates, polyether, sodium methyl silicate, and deionized water into a stirrer. The fluorosilicone super-weatherability water-in-water coating has the advantages of good weatherability, high tensile strength, good flexibility, good mechanical properties, low cost, high yield, and zero environmental pollution.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to fluorosilicon super weather-resistant water-in-water coatings. Background technique [0002] The definition of paint refers to a fine chemical product that is coated on the surface of an object by a specific construction method and cured to form a beautiful and continuous protective film with a certain strength on the surface of the object, or to form a coating film with a certain special function. It can cover various defects on the coated surface to make it beautiful, that is, decorative; it can control moisture, isolate corrosive gases such as carbon dioxide, sulfur dioxide, and hydrogen chloride in the air, and prevent the climate from affecting the coated object and the metal substrate. Rust, that is, has a protective function; it can give the surface of the coated object various colors and has a marking effect; in addition, the paint also gives the coated objec...
