摘　　要：本文以豆油脂肪酸,三羟甲基丙烷,新戊二醇,多元酸为原料,间苯二甲酸-5-磺酸钠为自乳化剂制备了自乳化型水性醇酸树脂,并将该水性醇酸树脂与氨基树脂交联固化制备了水性氨基醇酸烤漆。重点探讨了多元酸种类、助溶剂种类及水性醇酸树脂与氨基树脂的比例对水性氨基醇酸烤漆性能的影响。结果表明,当多元酸选用间苯二甲酸、助溶剂选用二丙二醇丁基醚、水性醇酸树脂与氨基树脂的质量比为2.8∶1时,水性氨基醇酸烤漆的漆膜硬度高达4 H,且具有非常优异的柔韧性及耐酸碱性能。Water based self-emulsifying alkyd resins were prepared from soybean oil fatty acid, trimethylolpropane,neopentyl glycol and polyacid, and 5-sulfoisophthalic acid monosodium salt(5-SSIPA) as self-emulsifier. The waterborne amino-alkyd baking paint was prepared by crosslinking and curing the water-borne alkyd resin with amino resin.The effects of various kinds of polyacids, cosolvents and the ratio of water-borne alkyd resin to amino resin on the properties of water-borne amino alkyd paint were discussed. The results showed that when the polybasic acid was selected from isophthalic acid, the cosolvent was selected from dipropylene glycol butyl ether and the mass ratio of water-borne alkyd resin to amino resin was 2.8∶1, the film hardness of water-borne amino alkyd baking paint reached 4H, and it had excellent flexibility and acid and alkali resistance.
