摘要
以松节油为基本原料 ,通过D A加成反应和聚酯化反应合成了松节油伯羟基聚酯多元醇 ,并用多异氰酸酯组分将其交联固化 ,制备了松节油改性聚氨酯涂料。重点讨论了不同原料配比、反应时间等因素对聚酯化反应的影响 ,并对松节油改性聚氨酯涂料的性能进行了测试。
Polyester polyols and polyurethane baking varnishes modified by turpentine were made from condensation reaction and crosslinking.Effects of the ratio of components and the reaction temperature on their properties were discussed.The IR spectra were also studied.By performance testing,it has been confirmed that the varnish possessed good properties and could be used as polyurethane coatings.
