项目摘要

Dynamic mechanical properties and microstructure of an organic hybrid consisting of chlorinated polyethylene(CPE) and inorganic fillers such as carbon blacks, hindered phenol, hindered amine, and silica particles with some polar groups were investigated. In order to clarify the effects of hydro bond on molecular mobility of CPE, the hindered phenol and amine were added to CPE matrix. The fillers clearly exhibited two second-order transitions at 6 and 69℃ in addition to the melting : the transition at lower temperature is assigned to the glass transition. and the transition at higher temperature is considered to be caused by the dissociation of hydrogen bond between the hydroxyl groups of the fillers. When blending with CPE, part of the fillers molecules was dispersed into the CPE matrix, and most of them formed an filler-rich phase. As a result, a novel transition appeared above the glass-transition temperature of the CPE matrix. It was assigned to the dissociation of the intermolecular hydrogen bond between the a-hydrogen of CPE and the hydroxyl groups of fillers within the AO-80-rich phase. Dynamic mechanical properties and microstructure of CPE/filler hybrid were capable of being controlled by the thermal treatment. Consequently, the CPE/filler hybrid is a good damping material and shows a shape memory effect.

研究了由氯化聚乙烯（CPE）和无机填充剂组成的有机杂种的动态机械性能和微观结构，例如碳黑色，阻碍苯酚，阻碍胺和二氧化硅颗粒以及一些极性基团。为了阐明水杆对CPE分子迁移率的影响，将阻碍的苯酚和胺添加到CPE基质中。除了熔化之外，填充剂在6和69℃上清楚地暴露了两个二阶转变：在较低温度下的过渡被分配给玻璃跃迁。并且在较高温度下的过渡被认为是由填充剂羟基之间的氢键解离引起的。当与CPE融合时，部分填充分子分散到CPE基质中，其中大多数形成了富集的相。结果，新颖的过渡出现在CPE基质的玻璃传输温度上方。它被分配给了CPE的A-氢和富含AO-80富相中填充剂的羟基之间分子间氢键的解离。 CPE/填充物杂种的动态机械性能和微观结构能够通过热处理控制。因此，CPE/填充杂种是一种很好的阻尼材料，并显示出形状的记忆效果。
