Abstract

Blends of acrylonitrile butadiene rubber/high density polyethylene (NBR/HDPE) compatibilized by Chloroprene rubber (CR) were prepared. A fixed quantity of industrial waste such as marble waste (MW, 40 phr) was also included. The effect of the blend ratio and CR on cure characteristics, mechanical and swelling properties of MW-filled NBR/HDPE blends was investigated. The results showed that the MW-filled NBR/HDPE blends revealed an increase in tensile strength, tear, modulus, hardness and cross-link density for increasing weight ratio of HDPE. The minimum torque (M L) and maximum torque (M H) of blends increased with increasing weight ratio of HDPE while scorch time (ts2) cure time (tc90), compression set and abrasion loss of blends decreased with increasing weight ratio of HDPE. The blends also showed a continuous reduction in elongation at break as well as swelling coefficient with increasing HDPE amount in blends. MW filled blends based on CR provided the most encouraging balance values of overall properties.

摘要

丙烯腈-丁二烯橡胶/高密度聚乙烯（NBR/HDPE）共混物用氯丁橡胶（CR）进行增容。还加入了一定数量的工业废料，如大理石废料（MW，40phr）。研究了共混比对 CR 对填充 MW 的 NBR/HDPE 共混物的硫化特性、力学性能和溶胀性能的影响。结果表明，随着 HDPE 重量比的增加，MW 填充的 NBR/HDPE 共混物的拉伸强度、撕裂强度、模量、硬度和交联密度均有所提高。共混物的最小转矩（M L）和最大转矩（M H）随 HDPE 重量比的增加而增加，而焦烧时间（ts2）、硫化时间（tc90）、压缩永久变形和磨耗损失随 HDPE 重量比的增加而降低。随着共混物中 HDPE 含量的增加，共混物的断裂伸长率和溶胀系数也连续下降。基于 CR 的 MW 填充共混物提供了最令人鼓舞的整体性能平衡值。
