中文摘要本研究用醇还原法将白盐前驱物还原於碳黑粉体表面，碳黑亦先以双氧水於高温(90oC)作改质处，使其表面形成含氧官能基，以促进白米颗於液体溶剂中的有效分散。

Two-component waterborne polyurethane paint composed of acrylic dispersion and hydrophilically-modified polyisocyanate has fast dry time, good adhesion, flexibility, impact resistance, but poor water and chemical-resistance. The dry time becomes shorter with the increase of glass transition temperature and the decrease of acid value; the gloss of the film decreases with the increases of hydroxyl value, acid value and Tg of emulsion polymer; higher Tg polymer leads to harder film.

将制得的丙烯酸分散体与亲水改性多异氰酸酯组分配制水性双组分聚氨酯涂料，发现漆膜表干和实干比较快，干燥时间随玻璃化温度升高而缩短，随酸值的增加而增加；附着力、柔韧性和冲击强度比较好；光泽随分散体羟值、酸值的增加和玻璃化温度升高而降低；硬度随玻璃化温度升高而升高；较高的酸值使涂料的耐化学品性和耐水性较差，羟值在100mgKOH/g时较好，而酸值应尽可能低。
