摘　　要：合成了在乳液中分散良好的多异氰酸酯,研究了亲水基团的相对分子质量、类型、加入量以及多异氰酸酯类型对其在羟基丙烯酸酯乳液中的分散性能和对涂料性能的影响,讨论了pH值与涂料适用期的关系。A polyisocyanate having good dispersibility in emulsion was synthesized. The influence of molecular weight, types, adding amount of hydrophilic groups and polyisocyanate types on their dispersibility in hydroxyl acrylic emulsion and coatings properties were studied, and relationship between pH value and potlife was discussed.
