采用预水解的方法,用硅烷偶联剂KH-845-4对凹凸棒土进行有机表面改性,并制备有机凹凸棒土/SBR复合材料,研究该复合材料的物理性能和结构。研究结果表明:由于硅烷偶联剂KH-845-4成功地包裹到了凹凸棒土的表面并且提高了凹凸棒土和SBR分子之间的结合力,制得的有机凹凸棒土/SBR复合材料具有良好的力学性能。
Using prehydrolysis method, organic surface modification of attapulgite with silane coupling agent KH-845-4 and preparation of organic attapulgite / SBR composites were carried out to study the physical properties and structure of the composites. The results show that the organic attapulgite / SBR composites with the silane coupling agent KH-845-4 successfully wrapped onto the surface of attapulgite and the binding force between the attapulgite and the SBR molecules increased Good mechanical properties.
