桐油基水性聚氨酯乳液的合成及性能

摘要

采用从桐油自制的桐酸甲酯酸酐MEA和1,4-丁二醇反应,制备了桐油基多元醇TBPO,并进一步以TBPO、异佛尔酮二异氰酸酯和二羟甲基丙酸为原料,制备了桐油基水性聚氨酯乳液。采用红外光谱仪对MEA、TBPO和水性聚氨酯进行了表征,验证了产物的结构与预测相符,对水性聚氨酯的热性能及乳胶粒直径及分布进行了表征。结果表明,以桐酸甲酯酸酐为原料可以制备具有耐热性好、粒径分布窄的水性聚氨酯乳液,该水性桐油基聚氨酯可用作水性涂料。

Abstract：

Tung oil-based polyols (TBPO) was synthesized by the reaction of methyl eleostearate anhydride (MEA) and 1,4-butanediol, and then the waterborne Tung oil-based polyurethane (WBTPU) emulsion was prepared using TBPO, isophorone diisocyanate and 2,2-dimethylolpropionic acid as raw materials. MEA, TBPO and WBTPU were characterized by FTIR, by which the molecular structures of the materials were verified. The thermal properties of polyurethane and the particle size and its distribution of polyurethane emulsion were characterized. The results indicate that the polyurethane from methyl eleostearate anhydride is with high heat-resistance and the particle size of polyurethane emulsion is monodispersed. The prepared Tung oil-based polyurethane can be used in the coatings fields.

Keywords： waterborne polyurethane； Tung oil； polyols； coatings； particle size distribution
