摘要
Abstract
Poly(ammonium phosphate)(APP),piperazine modified poly(ammonium phosphate)(Pi-APP) and melamine polyphosphate(MPP) were combined into a certain proportion to improve the flame retardancy of polypropylene(PP).The flame retardant and mechanical properties of the flame retarded PP of APP,Pi-APP and the compound flame retardant system were investigated by method of thermogravimetric analysis(TGA) and vertical burning test,limited oxygen index (LOI),tensile impact tests and scanning electron microscope(SEM).The results show that:the compatibility between Pi-APP and matrix PP is better.When adding 20％Pi-APP and 5％MPP,PP can reach UL 94V-0(3.2 mm and 1.6 mm),and the ultimate oxygen index can reach 32.5％,while maintaining good mechanical properties.关键词
