本文讨论了无机填料对高光泽聚丙烯性能的影响。PP T30S作为基体料,与Ca CO3、Ba SO4、滑石粉、云母、玻璃微珠等无机填料按一定比例混合,PP取80%,其余无机填料各选取20%,加入少量的抗氧剂168。实验表明,几种无机填料都会使PP光泽度有所下降,影响最小的是硫酸钡,硫酸钡是制备高光泽聚丙烯的最佳填料。六种填料填充后,样品的拉伸强度、弯曲强度、冲击强度较原料比都有所下降。
This article discusses the effects of inorganic fillers on the properties of high gloss polypropylene. PP T30S as the base material, and CaCO3, Ba SO4, talc, mica, glass beads and other inorganic filler by a certain percentage of mixing, PP take 80%, the remaining 20% of each selected inorganic fillers, adding a small amount of antioxidant 168. Experiments show that several inorganic filler PP gloss will have declined, the least affected is barium sulfate, barium sulfate is the best filler for the preparation of high gloss polypropylene. After the six fillers are filled, the tensile strength, flexural strength and impact strength of the samples are all lower than those of the raw materials.
