摘　　要：针对传统水包水多彩涂料容易出现彩粒渗色、串色、聚集和后增稠稳定性不足的问题,提出用自制有机硅改性丙烯酸酯乳液为基础漆,用有机改性膨润土(GTS)为保护胶制备新型水包水多彩涂料,并对水包水多彩涂料配方进行优化。结果表明:水包水多彩涂料最佳配方为:基础漆中乳液用量28%;羟乙基纤维素用量0.7%;保护胶浓度8%;保护胶与基础漆质量比5∶7;增稠剂用量0.5%;以给配方制备的水包水多彩涂料彩粒边界清晰分明,对比度高,强度好,没有混合和串色现象,装饰效果良好,已经达到了水包水涂料HG/T 4343—2012化工行业标准。In view of the shortage of color penetration,color matching,aggregation and post thickening of traditional waterborne multicolour coatings,a new type of waterborne multicolor paint was prepared with self-made silicone modified acrylate emulsion as base paint and organic modified bentonite(GTS)as protective adhesive.The formulation of water in water multicolor paint was optimized.The results show that the best formula of water in water multicolor coating was as follows:the amount of emulsion in basic paint was 28%;the dosage of hydroxyethyl cellulose was 0.7%;protective glue concentration was 8%;the mass ratio of protective adhesive to base paint was 5∶7;the dosage of thickener was 0.5%.The water in water colorful coating prepared with the above formula has clear boundary,high contrast,good strength,no mixing or color matching,and good decorative effect,which has reached the chemical industry standard of water in water coating,HG/T 4343—2012.
