水性环氧改性醇酸树脂及其涂料的制备

摘要

A waterborne epoxy modified alkyd resin and its coatings were prepared by epoxy resin, trimellitic anhydride and self-made additives. The various factors affecting the performance of resin and coatings were discussed. The results showed that the performance of coatings was equal to that of solvent coatings.%采用环氧树脂为改性剂，以及偏苯三酸酐和自制助剂改性，制成了水溶性且性价比较高的水性环氧改性醇酸树脂及其涂料。讨论了各种因素对树脂和涂料性能的影响。试验结果表明：配制底漆的性能与溶剂型涂料相当。
