Problems solved by technology

However, in practical applications, the requirements for FRP grating are slightly different according to different occasions. In some places with open flames, the flame retardancy and anti-corrosion performance of FRP grating are required to be very high. Anti-corrosion and flame-retardant properties cannot meet the needs of actual use at the same time

Description

technical field [0001] The invention relates to the technical field of FRP gratings, in particular to a flame-retardant and corrosion-resistant modified unsaturated polyester resin FRP grating. Background technique [0002] The FRP grating is composed of a glass felt skeleton and a resin coating wrapped around the skeleton. Because of the corrosion resistance and pressure resistance of the FRP grating, the application of FRP has developed very rapidly in recent years. However, in practical applications, according to different occasions, the requirements for FRP grating are slightly different. In some places with open flames, the flame retardant performance and anti-corrosion performance of FRP grating are required to be very high. Corrosion resistance and flame retardant properties cannot meet the needs of actual use at the same time. SUMMARY OF THE INVENTION [0003] In order to solve the technical problems existing in the background art, the present invention proposes a...
