ABS/PVC共混改性的研究

Modification of ABS/PVC Blend

考察了PVC含量对ABS/PVC共混体系性能的影响。为了进一步提高共混体系的性能 ,在体系中分别加入CPE、MBS做为第三组分。通过性能比较 ,发现MBS可有效提高共混体系的综合性能。为了增加共混体系的阻燃性能 ,加入助阻燃剂Sb2 O3。

Effects of PVC content on the property of ABS/PVC blend was studied.In order to improve the properties of the blend,the ratio of ABS/PVC was pitch upon.Then CPE and MBS were added in the blend as compatibilizer respectively.Compared their properties,it is found that MBS can improve the properties of ABS/PVC better.In order to improve the flame retardance of ABS/PVC blend,Sb 2O 3 was added into the composite.The result showed that the flame retardance of the blend was upgraded greatly.
