Water-based acrylic emulsion as well as preparation method and application thereof

The invention discloses a water-based acrylic emulsion and a preparation method thereof. The water-based acrylic emulsion is prepared from the following solid raw materials in parts by weight: 30-90 parts of acrylate monomers, 10-70 parts of functional monomer acid, 0.1-1 part of a cross-linking agent, 0.1-1 part of an anionic emulsifier and 0.5-5 parts of a nonionic emulsifier. According to the composition, by controlling the cloud point of the nonionic emulsifier and the compounding proportion of the nonionic emulsifier and the anionic emulsifier, the prepared polymer can stably exist in a high-ethanol or other alcohol solvent system, and has excellent compatibility with ethanol, water-based color concentrate and the like, so that the composition can be used in the field of wood lacquer color retouching. 本发明公开了一种水性丙烯酸乳液及其制备方法，其采用包括以下固体分的原料制得：丙烯酸酯类单体30-90重量份，功能单体酸10-70重量份，交联剂0.1-1重量份，阴离子乳化剂0.1-1重量份，非离子乳化剂0.5-5重量份。所述组合物通过控制非离子乳化剂的浊点及其与阴离子乳化剂的复配比例，使得制备的聚合物在高乙醇或其它醇类溶剂体系中可以稳定存在，与乙醇及水性色精等具有优异的相容性，从而满足木器漆修色领域使用。
