高光泽聚丙烯的研制

The Preparation of High Gloss PP

研究用降解剂、成核剂和光泽剂为主要助剂提高聚丙烯光泽度，其中，成核剂效果最好，添加量达到０３％时，光泽度的提高趋于平缓，光泽剂添加量１５％为最佳。与其它助剂相比，无机物对表面光泽度有一定影响。在降解剂、成核剂、光泽剂分别加入量为０００６％、０３％、１０％～１５％时，三者有较好的协同作用，材料的表面光泽度达到最佳值１４６，超过ＡＢＳ的表面光泽度。

Degradable,nucleation and glossy agent were employed in PP to improve its glossiness.The experiment results showed that the nucleation agent was the most effective.When nucleation was added 0 3%,the glossiness tended to stableness.The most effective rang of glossy agent was 1 0%～1 5%.The inorganic substance had certain effect on the surface gloss.When adding 0 006% degradables, 0 3% nucleation and 1 0%～1 5% glossy agent,the glossiness of PP was 146.It was optimum and higher than ABS.
