摘要
马来酸二乙酯与伯胺类化合物反应,制备聚天门冬氨酸酯。由此制备的聚天门冬氨酸酯聚脲,可降低A/B两组分的反应速度,延长凝胶时间。改善了涂层的表面缺陷,增加附着力,方便施工,扩大聚脲材料的应用范围。
Polyaspartic esters are prepared by the reaction of diethyl maleate and primary amines. Thusprepared polyaspartic polyurea can reduce the reaction speed of A and B components, and prolong the jeltime. The surface imperfection of the coating is improved, the adhesion is increased, the construction ismore convenient and the application fields are expanded.
