摘　　要：分析了真石漆配方,考察了成膜助剂、防冻剂、砂子配比对真石漆水痕恢复的影响,发现成膜助剂和砂子配比对水痕恢复性能影响较大,即通过降低乳液的成膜温度可以改善水痕恢复性能,但是成膜温度过低会造成黏结强度不达标,以及冻融不太稳。通过核壳工艺、亲水单体、交联单体的配合使用制备出了水痕恢复性能好的苯丙真石漆乳液,能够达到轻痕的效果。Sand textured coatings formula was analyzed. The influence of additives, anti-icing agent, sand ratio on the water mar recovery property was investigated. The results showed the additives ratio and sand ratio had great influences on water mar recovery. To reduce the film forming temperature could improve the water mar recovery property. However, low temperature might result in weak cohesion strength and poor anti-icing property. Through core-shell technology, by adding hydrophilic monomer and crosslink monomer, styrene acrylic emulsion with good water mark recovery was prepared.
