低温等离子法提高芳纶布与硅橡胶粘接性能的研究

摘要

采用低温等离子法处理芳纶布,并在硅烷偶联剂的作用下,考查低温等离子处理对芳纶布与硅橡胶粘接性能的影响.研究结果表明,经低温等离子处理过的芳纶布,其表面粗糙度和羟基含量明显提高,同时在乙烯基三乙氧基硅烷(A151)作用下,芳纶布与硅橡胶间的粘接性能明显改善,且随着处理时间的延长,改善幅度增加.%The influence of low temperature plasma on the adhesion behavior between silicone rubber and aramide fabric by the action of silane coupling agent is studied.The result indicates that the roughness and the content of hydroxyl groups on the aramid fabric surface increase after it is treated by plasma.The adhesion property between silicone rubber and treated aramid fabric which subsequently treated by VTPS is evidently improved. The promoting action increases when the treating process is protracted.
