Waterborne high temperature resistant paint and preparation method thereof

Abstract

The invention belongs to the technical field of coatings, and relates to a waterborne high temperature resistant paint and a preparation method thereof. The waterborne high temperature resistant paintcomprises the following components in parts by mass: 55-65 parts of waterborne modified silicone resin, 15-30 parts of waterborne aluminium silver paste, 1-8 parts of a drier, 2-7 parts of a levelingagent, 2-7 parts of a dispersant and 8-15 parts of water. The waterborne high temperature resistant paint has excellent high temperature resistance and excellent corrosion resistance, adhesive forceand impact-resistant strength.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and relates to water-based coatings, in particular to a water-based high-temperature-resistant paint and a preparation method thereof. Background technique

[0002] In recent years, due to the deterioration of the ecological environment, environmental protection has attracted more and more attention from the world. Various countries have formulated relevant regulations to strictly limit the emission of volatile organic compounds (VOC) in coatings. Solvent-based coatings contain a large amount of VOC components, which not only pollute the environment and waste resources, but also endanger people's health. With the development of the coating industry and painting towards low pollution, low-pollution water-based coatings, light-cured coatings, powder coatings and high-solid coatings have become the development direction of coatings. Among them, compared with other low-pollution coatings, water-ba...
