摘要
以氯化聚乙烯(CPE)、马来酸酐接枝聚乙烯(MAPE)、聚丙烯酸酯(ACR)为改性剂,采用二辊开炼机制备PVC/PE共混体系及其木塑复合材料(WPC),并采用热压成型的方法制备材料试样。考察了改性剂和木粉对PVC/PE及其WPC力学性能、加工性能及动态热机械性能的影响。结果显示:CPE能够显著提高PVC/PE共混体系的机械性能,使材料加工性能下降,储能模量降低;MAPE则能使PVC木塑复合材料力学性能大幅提高;ACR则能够提高材料的加工性能,使材料储能模量增大;木粉的加入使复合材料加工性能大幅下降,材料储能模量提高,损耗因子下降。
Using CPE （ chlorinated polyethylene）, MAPE （ polyethylene-g-maleic anhydride）, and ACR （polyacrylate） as the modifiers, PVC （ polyvinyl chloride）/PE （polyethylene） blends and its wood-plastic composites（WPC） were prepared by an open mixing mill, and the sample laminates were prepared by a hot press molding machine. The effect of modifiers and wood-flour on the mechanical property, processing characteristics and dynamic thermal mechanical properties of the PVC/PE and its WPC materials were investigated. The result showed： CPE can improve the mechanical properties of PVC/PE blends dramatically, but the processing properties and storage modulus were decreased. In the same way, MAPE can improve the mechanical properties of PVC/PE WPCS obviously. ACR can improve the processing properties and storage modulus of PVC/PE blends and its＇ WPCS. On the contrary, wood-flour made the processing properties of WPC decreased evidently, but the storage modulus was improved and loss factor was decreased.
