摘　　要：采用物理杂化法,用水性丙烯酸乳液与自制水性醇酸树脂混拼,选用合适的助剂制备出一种性能优良的水性醇酸-丙烯酸杂化涂料.通过对杂化涂料的性能测试与表征,结果表明:水性丙烯酸乳液HG-100的加入能显著提高水性醇酸涂料的干燥性能;当防闪锈剂H98的用量为0.6%、催干剂S-1440的用量为1.4%、消泡剂Su425的用量为0.2%时,制得的水性醇酸-丙烯酸杂化涂料不闪锈,表干时间为10 min,实干时间为4h,附着力为1级,光泽为92%,耐水性>180 h.The waterborne alkyd acrylic hybrid coating was prepared by mixing the waterborne acrylic emulsion with homemade waterborne alkyd resin and selecting suitable additives. Through testing and characterizing the properties of the hybrid coatings, the results showed that the addition of waterborne acrylic emulsion HG-100 significantly improved the drying properties of waterborne alkyd coatings. When the dosage of H98 is 0.6%, the dosage of drying agent S-1440 is 1.4%, and the dosage of defoamer Su425 is 0.2%, the waterborne alkyd acrylic acid hybrid is obtained. Coating surface drying is 10 minutes, solid drying is 4 hours, adhesion grade is 1, gloss is 92%, water resistance greater is more than 180 hours.
