Preparation of high-performance anti-aging polypropylene by modified nano-TiO and calcium sulfate whisker grafted acrylonitrile composite PP

By employing the radical polymerization method, acrylonitrile (AN) was grafted on the surface of nano titanium dioxide (TiO 2 ), and the calcium sulfate whisker (CSW) was modified using the coupling agent KH570 to provide ultraviolet (UV)-absorption capacity. The prepared TiO 2 -PAN and CSW-PAN mate...

Description
Summary:By employing the radical polymerization method, acrylonitrile (AN) was grafted on the surface of nano titanium dioxide (TiO 2 ), and the calcium sulfate whisker (CSW) was modified using the coupling agent KH570 to provide ultraviolet (UV)-absorption capacity. The prepared TiO 2 -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. High-performance polypropylene was prepared by grafting acrylonitrile onto TiO 2 and CSW surfaces by suspension polymerization.
