Preparation method of nano kaolin filled powder rubber

The invention relates to a preparation method of nano kaolin filled powder rubber. According to the method disclosed by the invention, based on the advantage that most rubber has an own emulsion form, a water suspension of kaolin and a rubber emulsion are blended, and a coagulant is added for flocculation, washing and water removal, so that the nano kaolin filled powder rubber nano composite material is obtained. The method disclosed by the invention is simple to operate, low in cost, wide in application range and easy to industrialize, and the kaolin can be uniformly dispersed in a rubber matrix in a nano-scale form by using the method disclosed by the invention. 一种纳米高岭土填充型粉末橡胶的制备方法。本发明的方法基于大多数橡胶均有自己乳液形式的优势，利用高岭土的水悬浮液与橡胶乳液进行共混，加入凝聚剂进行絮凝、洗涤，脱去水分，从而获得纳米高岭土填充型粉末橡胶纳米复合材料。本发明的方法操作简单、成本低、适用面广、易于工业化，使用本发明的方法可使高岭土在橡胶基质中能够以纳米级的形式均匀地分散。
