用于硅PU塑胶地坪的水性双组分聚氨酯涂料的研制

The Preparation of Waterborne Two Components Polyurethane Coatings for the Silicon Polyurethane Plastic Floor

采用羟基丙烯酸乳液及高效助剂制得水性双组分聚氨酯涂料的乙组分,以水可分散型异氰酸酯为甲组分,制得的双组分涂料在硅PU塑胶基材上具有极佳的附着力、耐化学介质性及耐候性,大大提高了硅PU塑胶地坪的耐久性。

The second component of waterborne two components polyurethane coatings was prepared by hydroxyl acrylic emulsion and high efficient additives. And the water dispersible isocyanate was as the first component. The prepared coatings had excellent adhesion,chemical resistance and weather resistance when it was painted on the silicon polyurethane plastic substrate,which greatly improved the durability of silicon polyurethane plastic floor.
