摘要
采用福建高岭土、伊利石类粘土矿粉（＜２×１０－６ｍ），经酸活化处理后，用１％硅烷偶联剂对其进行表面修饰；并利用ＩＲ光谱对亲水性粘土矿物的表面修饰方式进行初步的探讨．修饰后的粘土矿粉作为补强填料应用于橡胶体系，改善了填料与橡胶基体之间的复合性能，从而提高补强效果和室温硅橡胶的存放稳定性．
Saline modified clay fines are applied to the rubber system as reinforcing fillers. Their application improves the composite performance of rubber substrate and filler;and promotes the reinforcing effect and the storing stability of saline rubber at room temperature. For preparing saline modified clay,the clay mineral fines (2×10-6m) of kaolinite and illite originated in Fujian are activated by acid;and then surface modified by 0.01: 1. 00 saline coupling agent. For inquiring into the mode of surface modification, the hydrophilic clay minerals are inspected by infrared spectra.
