摘要 采用自己合成的端羟基水性聚氨酯分散体,加入流平剂、消泡剂、成膜助剂等,作为乙组分;采用六亚甲基二异氰酸酯三聚体(N75),加入二乙二醇二乙醚作为甲组分;制成了双组分水性聚氨酯木器漆。研究了甲、乙组分配比、成膜助剂、消泡剂等对产品性能的影响,测试了产品的硬度、附着力、耐水性等技术指标。 This article discusses the preparation of a water-borne two-component polyurethane wood varnish, which is composed of Part A and Part B; whereby Part B is a ready-made hydroxyl terminated water-borne polyurethane dispersion with flowing agent, deformer, coalescing agent,while Part A is made of hexamethylene diisocyanate(N75 HDI) with Diethylene glycol diethyl ether. It also studies results from the different ratios of Part A and Part B, coalescing agents as well as defoamers, and determines the hardness, adhesion and waterfastness of the resulting varnish.
