Abstract:

Based on the aqueous polyurethane which can provides a pleasant soft -touch feeling for its coating film, the effects of the type and amount of some additives, such as antifoaming agent, silane coupling agent, the elastic powder, wax dispersion, thickener and the aziridine crosslinking agent, on the properties of film adhesion, water resistance, scratch resistance were investigated. Finally, a kind of waterborne coatings for ABS plastics with silky, soft and shiny, good scratch resistant and excellent adhesion of the film, was prepared.

Key words: waterborne soft -feel coatings, ABS plastics, polyurethane

摘要： 选用能赋予涂膜柔软触感的水性聚氨酯为成膜物质，研究了消泡剂、硅烷偶联剂、弹性粉、蜡分散体、氮丙 啶交联剂和增稠剂等助剂的类型和用量对涂膜附着力、耐水性、耐划伤等性能的影响，制备了一种手感柔滑、光泽柔 和、耐划伤性好、附着力优异的水性 ABS塑料涂料。
