Problems solved by technology

However, PVDF fluorocarbon resin is a kind of UV-permeable resin, and the external light can easily pass through the fluorocarbon topcoat and irradiate the primer, which will cause the temperature of the primer to rise and decompose, which will easily lead to the overall damage of the coating. Damaged, corroded and aged steel structures
In addition, 20-25% rutile titanium dioxide is added to the formula of the above invention. As a pigment and filler, rutile titanium dioxide has the effect of reflecting light, but its own thermal conductivity is relatively large, so adding a large amount of it to the topcoat will make the surface The heat insulation ability of the paint decreases and the thermal conductivity increases, which will also aggravate the aging of the primer and even the steel structure

Abstract

The invention discloses a high-performance heat-insulating fluorocarbon paint. The paint comprises 45-60 parts of fluorocarbon resin, 3-8 parts of titanium dioxide, 20-30 parts of a functional filler,0-15 parts of a thermal insulation filler, 1-1.5 parts of ethylene glycol, 0.3-0.5 part of an alkali-swelling thickening agent, 0.2-0.3 part of a defoaming agent, 0.3-0.5 part of a leveling agent, 0.4-0.8 part of a dispersing agent, 1.5-3.5 parts of a film-forming aid and 25-40 parts of deionized water. The titanium dioxide and the functional filler formed by mixing ceramic microbeads and baritepowder are added into the high-performance heat-insulating fluorocarbon paint disclosed by the invention, so a paint film is endowed with better whitening and shading effects, the light transmission of the paint is reduced, the heat absorbed by the paint film can be reduced by reflecting solar radiation heat energy, and the goal of preventing the heat from being conducted through the paint film isachieved. The invention also discloses a preparation process of the high-performance heat-insulating fluorocarbon paint. With the preparation process, the fluorocarbon paint with high stability and proper viscosity can be prepared.
