选用亲水性异氰酸酯作为固化剂，硅酸镁锂作为保护胶，以分散体型羟基丙烯酸树脂和聚丙烯酸弹性乳液复配得到分散相，利用硅酸镁锂层间可交换的阳离子与羟乙基纤维素中的羟基之间的“凝胶化”反应，同时辅以羟基丙烯酸树脂与亲水性固化剂的交联作用来制备综合性能优异的质感型水包水多彩涂料。实验结果表明：当乳液复配比在 1∶4且掺量为 30%，固化剂的—NCO与羟基树脂的—OH物质的量之比为 1∶2，高浓度保护胶溶液掺量为 4%时，所制备的彩粒具有强度适中、色彩饱满度高、抗渗色能力较强，施工喷涂顺畅、无流挂，体系贮存稳定等特点，解决了水包水多彩涂料在生产和施工过程中常常出现的彩粒渗色、彩粒易破碎、喷涂均匀性欠佳等问题。
A water-in-water（w/w） multicolor coatings with excellent comprehensiveproperties was prepared based on the hydrophilic isocyanateas curing agent，lithium magnesium silicate as protective glue，combination of dispersed hydroxyl acrylic resin andelastic polyacrylic latex as dispersed phase，and by using the gelation reaction betweeninterlayer exchangeable cations in lithium magnesium silicate and hydroxyl groups inhydroxyethyl cellulose and the cross-linking of hydroxyl resin and hydrophilic curing agent.The experimental results showed that when the blending ratio of dispersion and latex was 1∶4， —NCO curing agent and —OH component was 1∶2（by molar ratio），and the bleeding was 4% with high concentration protective glue，the obtained color particles was characterized by its moderate stiffness，high color strength，and better color bleeding resistance，as well as goodapplicability without sagging and good storage stability.Some problems of the w/w multicolorcoatings during production and application，such as bleeding，easy breakage of color particles and unevensurface after spraying were solved.
