Abstract

By employing the radical polymerization method, acrylonitrile (AN) was grafted on the surface of nano titanium dioxide (TiO), and the calcium sulfate whisker (CSW) was modified using the coupling agent KH570 to provide ultraviolet (UV)-absorption capacity. The prepared TiO-PAN and CSW-PAN materials can improve the anti-aging performance and mechanical properties of polypropylene (PP) and meet the application requirements of high-performance polypropylene. Further, the obtained PP composites show prolonged service life and application scope, which can effectively reduce white waste and avoid both resource waste and environmental pollution.

摘要

通过采用自由基聚合法，将丙烯腈（AN）接枝到纳米二氧化钛（TiO）表面，并使用偶联剂KH570对硫酸钙晶须（CSW）进行改性，以赋予其紫外线（UV）吸收能力。制备的TiO-PAN和CSW-PAN材料可提高聚丙烯（PP）的抗老化性能和力学性能，满足高性能聚丙烯的应用要求。此外，所得的PP复合材料具有更长的使用寿命和更广泛的应用范围，可有效减少白色垃圾，避免资源浪费和环境污染。
