超细石膏-丁苯橡胶复合材料性能研究

A Study on the Performance of the Composite Material Ultrafine Gypsum/Butadiene-Styrene Rubber

研究超细活性石膏的制备方法及其对丁苯橡胶（SBR）的增强作用，实验结果表明，采用超音这气流粉碎的活化方法，所制的活性超细石膏能代替50％的白炭黑，其硫化胶具有较高的机械性能，透明度无明显差异。

A study is made on the method for preparing activated ultrafine gypsum and its effect for reinforcing butadiene styrene rubber. As shown experimentally, the activated ultrafine gypsum developed by supersonic airflow crush-activation can be used to replace 50% white carbon. The composite material activated ultrafine gypsum/butadiene-styrene rubber shows a good mechanical performance. No sharp difference of transparence can be discerned between its vulcanized rubber and that of white carbon.
