摘要水性醇酸树脂成本低、无污染、涂膜综合性能好，因而被广泛应用于各个领域。实验中采用醇解法合成了水性醇酸树脂。用红外光谱（IR)对产物进行了表征。选用蓖麻油、亚麻油、三羟基甲基丙烷、偏苯三酸酐为主要原料合成水性醇酸树脂。采用环氧树脂改性多元醇，然后以改性多元醇醇解植物油，再酯化缩聚、羟基化、中和的方法合成环氧改性水性醇酸树脂。以自制水性醇酸树脂和氨基树脂配合制备水性氨基醇酸树脂漆，氨基树脂和醇酸树脂的配比1:3，烘烤温度为160 ℃。对制备的水性氨基醇酸树脂烘漆进行了耐酸性、耐碱性、耐盐性、耐水解性等性能的测试，各项性能均接近或达到国家标准。20686

Title Preparation and Study of waterborne amino-alkyd paint
Abstract
Water-borne alkyd resin is wildly used in various fileds because of its low cost,pollution free,excellent properties.Alkyd resin was synthesized by Alcohol solution method.IR was applied to characterize the structure of the product.Castor oil , Linseed oil, trimethylolpropane and trimellitic anhydride were used as the main raw matterails to synthesize the water-borne alkyd resin.Water-based epoxy modified alkyd resin was synthesized through alcoholysising vegetable oil by Polyols which modified by epoxy resin,followed by esterification condensation,carboxylation and neutralized by salt.Waterborne amino-alkyd resin baking coatings was prepared by waterborne alkyd resin and high methyl ether amino resin,ratio between amino resin and waterborne alkyd resin is 1:3,baking temperature is 160℃。At last the performences of waterborne amino-alkyd resin baking coating such as acid resistance,alkali resistance, salt tolerance and resistance to hydrolysis were investigated, and these performence are all close to or reach the national standard.
Key words: Water-borne alkyd resin epoxy waterborne amino-alkyd resin baking coatings
