采用羟基丙烯酸树脂与聚天门冬氨酸酯制备喷涂用双组分聚脲 / 丙烯酸聚氨酯涂料,考察了涂料的基本性能,研究了两种树脂的配比、流平剂用量等对涂料性能的影响。 结果表明,当羟基丙烯酸树脂与聚天门冬氨酸酯的质量比为 35 : 45 ,流平剂用量为 0 . 3% 时,涂料具有优良的综合性能和耐老化性能。

The tow-component polyurea / acrylic polyurethane composite coating for spray was prepared by using hydroxyl acrylic resins and polyaspartic. The basic properties of the coatings were investigated, and the influences of the ratio of two resins and flow agent on the properties of coating were studied. The results show that when using hydroxy acrylic resin and polyaspartic at 35 : 45 , flow agent 0 . 3 % , the composite coating provides excellent comprehensive performance and anti-aging properties.
