摘要
聚烯烃发泡材料化学稳定性好、无毒,应用广泛,但由于其具有结晶性,因而发泡的控制比聚苯乙烯、聚氨酯困难。本文叙述了发泡聚烯烃在原料树脂选择,发泡剂,成核剂和填料的开发、选择;发泡方法、交联方法改进等方面的技术进展,以及发泡聚烯烃在汽车工业中的应用。
Expanded polyolefin has good chemical resistance,no toxicity,and wideapplications.But,owing to its crystallinity,the foaming process of polyolefinis more difficult to control than that of polystyrene and polyurethane.In thispaper,the technical advances on matrix resin selection,blowing agents,nu-cleation agentg,and fillers selection and improving of foaming and crosslink-ing methods for expanded polyolefin,as well its applications have been des-cribed.
