The Preparation of a High Strength Single Component Polyurethane Waterproof Paint

介绍一种高强度单组分聚氨酯防水涂料的研制,重点分析体系中聚醚比例、R值、粉料含量、催化剂对高强度单组分聚氨酯防水涂料成膜后力学性能的影响,结果表明高强度单组分聚氨酯防水涂料配比中控制聚醚质量比4∶5∶1、6∶6∶1、R值比例2.1、粉料含量为30%、催化剂含量在0.15%～0.20%范围内时制得的高强度单组分聚氨酯防水涂料涂膜物理性能和应用性能达到最佳。

This paper introduces the preparation of a high strength single component polyurethane waterproof paint, and mainly analyzes the polyether ratio, R value, powder content, and catalyst influence on the mechanical property of the high strength single component polyurethane waterproof paint after filming in the system. The result shows that when the high strcngth single component polyurethane waterproof paint is prepared with the control polyether mass ratio of 4 ： 5 ： 1 or 6 ： 6 ： 1, R value ratio of 2.1, powder content of 30% and catalyst content of 0.15%-0.20%, the high strength single component polyurethane waterproof paint film has the best physical property and application perfbrmance.
