Waterborne epoxy colored sand and preparation method thereof
The invention discloses waterborne epoxy colored sand and a preparation method thereof. The method comprises the following steps: step 1, weighing raw materials; step 2, synthesizing water-based resin by adopting epoxy resin, a water-based emulsifier and polyether amine; step 3, mixing 1.3 cyclohexanedimethylamine, isophorone diamine, an emulsifier, diethylene glycol monobutyl ether and water-based resin to prepare a component B; step 4, uniformly mixing transparent quartz sand and light calcium powder to obtain a sand powder material; 5, mixing water-based resin, sand powder, an antioxidant and water-based color paste to prepare a component A; and 6, compounding the component A and the component B according to the mass ratio of 10: 1 to obtain the waterborne epoxy colored sand. The invention also provides the waterborne epoxy colored sand prepared by the method. The waterborne epoxy colored sand prepared by the invention is free from sagging and collapse during construction in four seasons, high in hardness after curing, strong in adhesive force, outstanding in matte frosted texture, free from shrinkage and falling after long time, excellent in yellowing resistance and capable of being used for outdoor construction.
本发明公开了一种水性环氧彩砂及其制备方法，该方法包含：步骤1，称取原料；步骤2，采用环氧树脂、水性乳化剂、聚醚胺，合成水性树脂；步骤3，采用1.3环己二甲胺、异佛尔酮二胺、乳化剂、二乙二醇丁醚、水性树脂，混合制备B组分；步骤4，采用透明石英砂和轻钙粉，混合均匀，得到砂粉料；步骤5，采用水性树脂和砂粉料、抗氧剂、水性色浆，混合制备A组分；步骤6，采用A组分和B组分，按质量比10:1复配得到水性环氧彩砂。本发明还提供了通过该方法制备的水性环氧彩砂。本发明制备的水性环氧彩砂，四季施工不流挂、不塌陷，固化后硬度高、附着力强，哑光磨砂质感突出，时间久不收缩、不脱落，具有优异的耐黄变性能，可以室外施工。
