Abstract

The invention provides a novel heat-resistant fluorocarbon anticorrosive paint which is composed of a component A and a component B. The component A comprises the following components in parts by weight: 50-60 parts of fluorocarbon resin, 0.3-0.5 part of dispersing agent, 10-20 parts of solvent, 15-25 parts of pigment, 1-2 parts of leveling agent and 10-15 parts of anti-settling agent. The component B comprises the following components in parts by weight: 70-75 parts of curing agent and 25-30 parts of nano mica powder. The mass ratio of the component A to the component B is 5:1. The invention also provides a preparation method of the heat-resistant fluorocarbon anticorrosive paint. The heat-resistant fluorocarbon anticorrosive paint provided by the invention has favorable heat resistance.

Description

[0001] Technical field: [0002] The invention relates to an anti-corrosion coating, in particular to a heat-resistant fluorocarbon anti-corrosion coating and a preparation method thereof. [0003] Background technique: [0004] Anti-corrosion coatings are an indispensable coating in paints and coatings. They can prevent corrosion of metal materials and prolong their service life. They can be used as primers for ships, containers, automobiles, steel structures, and bridges. , metal anti-corrosion primer, oil pipe anti-corrosion coating, etc. The defect of the existing anti-corrosion coatings is that the heat resistance is not good, and it is easy to fail in summer and various high-temperature occasions, which limits its application range. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to provide a heat-resistant fluorocarbon anticorrosion coating with good heat resistance. [0007] In order to solve the problems of the tec...
