以有机磷和有机硅作为复配阻燃体系,对聚碳酸(酯PC/)聚乳(酸PLA)合金进行阻燃改性,制备了无卤阻燃PC/PLA合金,研究了合金的力学性能和阻燃性能。结果表明:随着复配阻燃剂中有机硅含量的增加,合金的拉伸强度、弯曲强度、弯曲模量略有降低,而冲击强度明显提高,并且合金的阻燃等级和氧指数均有所提高表,明有机磷和有机硅协同使用取得了较好的阻燃效果。
A flame retardant modified poly (carbonate PC) / polylactic acid (PLA) alloy was prepared by flame retardant of organophosphorus and organosilicon as flame retardant system. The flame retardant PC / PLA alloy was prepared. The mechanical properties of the alloy Performance and flame retardant properties. The results show that the tensile strength, flexural strength and flexural modulus of the alloy decrease slightly with the increase of the content of silicone in the compound flame retardant, while the impact strength increases obviously, and the flame retardancy and the oxygen index of the alloy have The improved table, clear organophosphorus and organic silicon synergies achieved better flame retardant effect.
