摘要
利用原位聚合的方法将聚甲基丙烯酸甲酯 (PMMA)包覆在滑石粉的表面 ,制得了含PMMA粘接层的滑石粉 /PVC复合材料。聚合物粘接层类似于粘接材料的粘接剂的作用 ,它很好地改善了复合材料的界面粘附性 ,提高了复合材料的机械强度。由于聚合物粘接层和基体聚合物的相互扩散以及界面内应力的存在 。
Polymethyl methacrylate(PMMA) coated talc was obtained by the in situ polymerization of MMA on the surface of talc.The composites containing PMMA adhesive layer was subsequently producted by filling the treated talc into PVC matrix.The polymer adhesive layer improves the mechanical proeperties of the composite for its interfacial adhesion similar to general adhesive agent.Since a mutual diffusion between adhesive layer and matrix and a innerstress on interfaces exist,there is a optimal thickness of adhesive layer in composites.
