摘要
研究了不同的阻燃方法对丙烯腈-丁二烯-苯乙烯(ABS)树脂燃烧性能、力学性能及加工性能的影响。单独添加低分子阻燃剂或自熄性聚合物无法使ABS在获得阻燃性的同时具有良好的力学、加工性能。当Sb2O3与聚氯乙烯(PVC)复配使用,且m(ABS)∶m(PVC)=(70∶30)~(30∶70)时,在氯化聚乙烯(CPE)及自制相容剂等的配合使用下,合金材料获得了优良的综合性能,阻燃级别达FV-0级,熔融指数为0.19g/min,冲击强度达23kJ/m2。
The influences of the different flame retarding methods on flammability, mechanical properties and fluidity in acrylonitrile butadiene styrene (ABS) preparation were studied. ABS could not have good mechanical properties, fluidity and flame resistance at the same time when flame retardant with low molecular weight or self-extinguished polymer was added alone to ABS. In coordination with chlorinated polyethylene and compatibilizer prepared, when Sb2O3 and polyvinyl chloride (PVC) were added to ABS after they were compounded together and the mass ratio of ABS and PVC was from 70:30 to 30:70, the composites possessed excellent comprehensive properties: the flame resistance reached up to FV-0 grade, the melt index was 0.19 g/min and the impact strength was 23 kJ/m2.
