摘要
简述了聚氨酯弹性地坪涂料的制备工艺,列举了该涂料的主要技术指标及测试结果。着重讨论了环氧树脂、弹性预聚物的各组分(线型聚醚、多元醇、甲苯二异氰酸酯)和预聚物的R_(Nco/OH)的控制及配漆时,NCO/OH当量比等因素对涂料性能的影响。
The production process of the PU elastic floor coatings is introduced. The main technical parameter and testing result of the PU elastic floor coatings is described. This paper focused on the influential factors upon the coatings properties. The influential factors include the components variation (i.e. epoxy, elastic prepolymer including linear polyether, polylol and TDI), R-NCO/OH adjustment during pre-polymerization and NCO/OH molal ratio during coatings application.
