摘　　要：目的:提高有机硅离型剂在聚乙烯(PE)基材上的锚固性。方法:以含氢硅油和烯丙基缩水甘油醚(AGE)在铂催化下进行硅氢加成反应,合成一种特殊结构的有机硅锚固剂(SEA)。结果:添加0.5 wt%的SEA到无溶剂加成型有机硅离型剂中,在70℃和90%相对湿度(RH)的条件下老化4 d,可以达到离型涂层无搓落的较好锚固性,并且具有较优的剥离力和残余接着率。结论:所制备的SEA对提升离型剂在PE基材上的附着性有较好的效果。Objective:To improve the anchorage of silicone release agents on polyethylene(PE)substrates.Methods:A silicone anchoring agent(SEA)with a special structure was synthesized by hydrosilicone oil and allyl glycidyl ether(AGE)catalyzed by platinum-catalyzed silicon-hydrogenation reaction.Results:The addition of 0.5 wt%SEA to the solvent-free addition molding silicone release agent and the aging at 70℃and 90%relative humidity(RH)for 4 days could achieve good anchorage without rubbing off the release coating,and had better peeling force and residual adhesion rate.Conclusion:The prepared SEA has a good effect on improving the adhesion of the release agent to PE substrate.
