中文摘要: |
以丁腈橡胶(NBR)/聚氯乙烯(PVC)为基体材料,加入以氯化聚乙烯橡胶为载体的预分散硫化剂和促进剂母胶粒制备NBR/PVC发泡材料,比较预分散橡胶助剂相对于传统粉末助剂在NBR/PVC发泡材料中的优势,主要考察胶料的硫化-发泡特性、物理性能及发泡情况。结果表明,在助剂活性成分添加量相同的条件下,添加预分散橡胶助剂的胶料发泡后密度更低,泡孔更均匀,拉伸强度也略优于添加粉末助剂的胶料。 |
英文摘要: |
Nitrile butadiene rubber(NBR)/polyvinyl chloride(PVC) foaming material was prepared by using NBR/PVC as the base material,and adding pre-dispersed curing agent and accelerator masterbatch particles with chlorinated polyethylene rubber as the carrier.The advantages of pre-dispersed rubber additives over traditional powder additives in NBR/PVC foamed materials were compared.The main focus was on the vulcanization-foaming characteristics,physical properties and foaming of the compound.The results showed that,when the addition amount of active ingredients of additives was the same,the foaming compound with pre-dispersed rubber additives had a lower density,more uniform cell structure,and tensile strength was slightly higher than that of the compound with powder additives. |
