为提高ABS树脂的性能,采用熔融共混法在ABS中添加不同量的有机化改性凹凸棒石粘土(OAT)制备ABS/OAT树脂复合材料,对复合材料进行了表征与测试分析,讨论了OAT的添加对复合材料热性能的影响,结果表明OAT粒子在复合材料中实现了均匀稳定分散,复合材料的维卡软化温度、最快热分解温度和玻璃化转变温度都比纯ABS提高,这表明热稳定性有了很大的提高。 In order to improve the properties of ABS resin, ABS / OAT resin composites were prepared by adding different amounts of organically modified attapulgite clay (OAT) to ABS by melt blending method. The composites were characterized and tested. The results show that the OAT particles are uniformly and stably dispersed in the composites. The Vicat softening temperature, the fastest thermal decomposition temperature and the glass transition temperature of the composites are all higher than that of the pure ABS. That the thermal stability has been greatly improved.
