Among all arc accidents, it is the most damaging to the human head. Therefore, in daily electrical construction and operation and maintenance operations, professional arc protection masks should be worn for personal protection. Anti-arc visor is a device used to protect human eyes from arc radiation. Polycarbonate (PC)-based composite material is a material made of polycarbonate resin mixed with other reinforcing materials or fillers. It has good heat resistance, chemical resistance and mechanical properties. Currently, the commonly used face screen materials on the market are prone to burning when exposed to arc, posing safety risks. To solve this problem, this article focuses on analyzing the performance of polycarbonate-based composites under combustion conditions. This article applies experimental and comparative methods to compare the burning rate, safety performance and maximum temperature of different additives. Experimental results show that after the high-temperature stabilizer is added, the burning rate of the material is reduced to 10, the safety is similar to that of flame retardants, and the maximum heat-resistant temperature is higher.
