本文介绍NBR/PVC-PVA共聚物共混胶料及硫化胶的配合与加工技术。通过测定粘度及扫描电子显微镜检验研究证明,共混体的相容性良好。使用通用的硫黄+促进剂硫化体系及硫黄+亚乙基硫脲并用体系进行硫化。对硫化胶的强度性能、在甲苯及发动机润滑油中的溶胀性、耐热老化性以及介电性能进行的研究表明,丁腈橡胶/PVC-PVA共聚物共混橡胶除可以用于加工耐油性橡胶工业制品外,还可用来加工电气绝缘材料。
This article describes the NBR / PVC-PVA copolymer blends and vulcanizates with the processing and processing technology. Through the determination of viscosity and scanning electron microscopy studies have shown that the compatibility of the blend is good. Use common sulfur + accelerator vulcanization system and sulfur + ethylene thiourea curing system. The research on the strength properties of vulcanizates, swelling in toluene and engine lubricating oils, heat aging resistance and dielectric properties shows that the addition of nitrile rubber / PVC-PVA copolymer blends can be used to process oil resistance Rubber industrial products, but also can be used to process electrical insulation materials.
