丙烯酸改性水性醇酸树脂的合成及性能的研究
|
摘要
水性醇酸树脂存在硬度低、干燥慢等问题。若使用丙烯酸链段对水性醇酸树脂进行改性,其产物以上性能将得到改善。文章采用脂肪酸法合成中间体,经接枝丙烯酸改性得到水性醇酸树脂,并探究了不同丙烯酸单体用量及种类对树脂性能的影响。
Waterborne alkyd resin has the problems of low hardness, slowly dry speed. If the waterborne alkyd resin was modified by using acrylic resin, the properties of the product would be improved. In this paper, the waterborne alkyd resin was modified by acrylic resin that grafted with intermediate synthesized by fatty acid method. The influences of the amount and types of acrylic acid on the performance of resin were investigated.
