电子产品塑料外壳上配套UV面漆使用的水性底漆及其制备方法
摘要：
本发明公开了一种电子产品塑料外壳上配套UV面漆使用的水性底漆，其特征在于，包括乳液组和交联剂组，其中，以所述乳液组为A组，主要由自交联水性丙烯酸乳液和水性聚氨酯树脂分散体构成，所述自交联水性丙烯酸乳液的质量分数为15~30%，所述水性聚氨酯树脂分散体的质量分数为15~35%；以所述交联剂组为B组，由氮丙啶交联剂和去离子水构成，所述氮丙啶交联剂的质量分数为30~50%，所述去离子水的质量分数为50~70%；所述A组与B组之间的质量比为20~30:1。本发明还公开该水性底漆的制备方法。该水性底漆具有较好的基材的润湿附着以及耐水性，并提高UV面漆在水性底漆上的附着，从而改善整个漆膜的物理化学性能。
摘要（英）：

The invention discloses an aqueous primer matched with UV finish on an electronic product plastic shell. The aqueous primer is characterized in that the aqueous primer comprises an emulsion group and a crosslinking agent group, wherein the emulsion group is mainly formed by 15-30mass% of a self-crosslinked aqueous acrylic emulsion and 15-35mass% of an aqueous polyurethane resin dispersion; the crosslinking agent group is formed by 30-50mass% of an aziridine crosslinking agent and 50-70mass% of deionized water; and a mass ratio of the emulsion group to the crosslinking agent group is 20-30:1. The invention also discloses a preparation method of the aqueous primer. The aqueous primer has good substrate wetting adhesion and waterproof property, and improves the adhesion of the UV finish on the aqueous primer in order to improve the physical and chemical performances of a whole paint film.
