木质素废旧聚氨酯制备轻型阻燃保温材料试验
Light Flame Retardant Insulation Foam Materials Preparation Modified with Lignin and Old Polyurethane
摘要
Abstract
According to the ratio of phenolic resin,flame retardant agent,foaming agent,emulsifier,alkali lignin, lignin liquefaction of waste polyurethane, the waste polyurethane was prepared. The results show that:with the increase of curing agent, the shortening of curing time, the increase of apparent density, the enhancement of compressive strength, foam quality is better;adding flame retardant aluminum hypophosphite and diethyl aluminum hypophosphite can significantly improve the retardancy of phenolic resin;the effect are the best adding 5g aluminum phosphate and two ethyl aluminum hypophosphite. The light flame retardant insulation material has advantages of phenolic resin foam, improves the flame retardancy due to the addition of lignin, and using polyurethane as additive can greatly reduce the cost of production, protect environment, improve the utilization rate of resources.关键词
