AI Technical Summary
Fiberglass decorative panels have insufficient heat resistance and flame retardancy, making them prone to cracking under impact. Furthermore, existing resin materials are quite brittle and have poor impact resistance.
A mixture of phenolic resin and melamine-based curing agent is used as the resin material, and flame-retardant fillers such as aluminum hydroxide, magnesium hydroxide and silica are added. Combined with coupling agent, dispersant, wetting agent and defoamer, a highly filled flame-retardant system is formed. Glass fiber prepreg sheets are prepared through specific impregnation and curing processes.
It improves the flame retardant properties and mechanical strength of pre-impregnated fiberglass sheets, enhances the stability of the char layer, improves high-temperature resistance and dimensional stability, and reduces VOC emissions, making it suitable for fireproof board cores in the construction industry.
