摘　　要：通过使用硅、铝等材料对钛白粉进行无机与有机改性,使得钛白粉达到干粉白度97、着色力117%,在乳胶漆中600 h不起泡,不剥落、无裂纹;粉化≤1级,变色≤2级。并与国内知名企业的PVC粒料进行吹膜成型,其力学性能中的拉伸强度与冲击强度等指标得到了明显的改善。Titanium dioxide was modified by inorganic and organic materials such as silicon and aluminum,make it to whiteness 97,the coloring power 117%,no blistering peeling and crack in emulsion paint for 600 h;pulverization≤1 grade,discoloration≤2 grade.Blow molding with PVC granules from domestic well-known enterprises,the mechanical property of the composites are improved obviously.
