Problems solved by technology

This coating usually uses two types of base materials: solvent-based base materials based on acrylic acid, branched polyester and other resins, and water-based base materials based on sodium silicate. The solvent-based base material itself is not resistant to high temperatures. This type of coating mainly obtains high temperature resistance by adding a large amount of ceramic fillers, but a large amount of additives will inevitably reduce the internal strength of the coating, thereby affecting the normal use of the material; although the water-based base material based on sodium silicate can withstand high temperature , but the adhesion to the FRP grating with phenolic resin, unsaturated polyester resin, etc.

Abstract

A refractory paint for the grate made of glass fibre reinforced plastics contains component A and component B, which are proportionally mixed before used. Said component A is prepared from organosilicon resin modified organic resin, high-temp stable pigment and filler, flame retarding-smoke inhibiting agent, coupling agent, solidifying promoter, and UV absorbing or shielding assistant. Said component B is polyurethane solidifying agent containing NCO. Its advantages are high resistance to high temp (900 deg.C) and weatherability and low smoke density at high temp.

Description

technical field [0001] The invention relates to a high-temperature-resistant coating for FRP grids. Background technique [0002] FRP grating is a kind of glass fiber reinforced plastic products. Because of its advantages of light weight, high strength, chemical corrosion resistance, electrical insulation, heat insulation, excellent designability and constructability, it has been rapidly expanded from the initial application in military industry to construction, shipbuilding, automobile, petrochemical and other fields. field. However, since FRP grating is made of synthetic resin (such as epoxy, phenolic, unsaturated polyester resin, etc.) It is also flammable and emits toxic gas and a lot of smoke when burned. According to statistics, about 80% of the fatal accidents in fires are caused by suffocation of toxic gases and smoke produced during the thermal decomposition of materials in the early stage of fire. The best way to solve this problem is to apply a layer of paint ...
