改性煤系高岭土矿粉填充橡胶的结构与性能

STRUCTURE AND CHARACTERISTICS OF MODIFIED COAL SHALE FILLER USED AS NR FILLINGS

以煤系高岭土为主要原料通过相对富集，超细粉碎、表而改性处理等方法，得到一种橡胶填充剂MUCKP。用它代替通用炭黑作为橡胶的补充填充剂，制备了胶片，对填充后的橡胶进行了应用性能研究。结果表明：用于天然橡胶时，当填充剂粒度小于400目时，已有较好的补强作用，其主要性能指标类似于通用炭黑，可以部分等量替换碳黑作为橡胶的补强填充剂。取代量在20％-25％之间。

Using coal shale as raw material, a new reinforced filler of NR was prepared by uhrafine crush and surface modification, This paper discussed the affecting factors. The experimental result indicated that coal shale could replace partial carbon as Nit reinforced agent.
