Problems solved by technology

[0002] At present, China's transportation has entered a golden period of development. The coatings used for the exterior decoration of most vehicles and equipment are mostly polyurethane paints, and a small amount of fluorocarbon paints are used. A large amount of VOC will be released during production and construction, and polyurethane paints and The curing agent used in fluorocarbon paint is toxic polyisocyanate, which not only poses health hazards to production and construction personnel, pollutes the environment, and is easy to burn and smoke in high-temperature environments, producing toxic gases and causing fire hazards

Abstract

The invention provides a nano-ceramic coating for 600°C-resistant working vehicles. The coating includes component A and component B, wherein component A is composed of the following raw materials in parts by weight: acidic silica sol: 55-70 parts, Inorganic pigment: 8-20 parts, whisker silicon: 4-6 parts, silicon carbide fiber: 4-6 parts, graphene: 1-2 parts, other fillers: 7-15 parts, dispersant: 0.5-1.5 parts, Leveling agent: 0.5-1 part, wherein component B is composed of the following raw materials in parts by weight: siloxane: 86-92 parts, non-stick additive: 1.5-3 parts, solvent: 5-13 parts. The 600°C-resistant nano-ceramic paint for working vehicles prepared by the invention can be self-dried at normal temperature, and is used for exterior decoration of high-temperature working vehicle equipment.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano-ceramic coating for 600°C-resistant operating vehicles, and at the same time, the invention also relates to the preparation and construction process of the coating. Background technique [0002] At present, China's transportation has entered a golden period of development. The coatings used for the exterior decoration of most vehicles and equipment are mostly polyurethane paints, and a small amount of fluorocarbon paints are used. A large amount of VOC will be released during production and construction, and polyurethane paints and The curing agent used in fluorocarbon paint is toxic polyisocyanate, which not only poses health hazards to production and construction personnel, pollutes the environment, and is easy to burn and smoke in high-temperature environments, producing toxic gases and causing fire hazards. However, many vehicles and equipment such as fire trucks, dec...
