摘要
研究了反应注射成型(RIM)聚氨酯弹性体对玻璃的粘接性能,考察了聚醚多元醇相对分子质量、扩链剂、催化剂和异氰酸酯对其粘接性能的影响。结果表明,以氨酯改性二苯基甲烷二异氰酸酯(MDI)做异氰酸酯组分,聚醚多元醇相对分子质量为6 000,1,4-丁二醇做扩链剂,使用自制的延迟胺复合催化剂,异氰酸酯指数为98时弹性体对玻璃具有良好的粘接性能。
This experiment is the study of the adhesion between RIM polyurethane elastomer and glass.The effect of polyether molecular weight,chain extender,catalyst and isocyanate on its peel strength was investigated.The results showed that the products which have good adhesion were gained using urethane modified MDI,polyether with a molecular weight of about 6000,chain extender 1,4-BG,delayed amine catalyst and controlling the isocyanate index with 98.
