摘　　要：使用水性双组分聚氨酯乳液及固化剂技术开发出具有优异的耐涂鸦性能,和高度环境友好的水性内外墙可擦洗的绘画涂料。研究了水性聚氨酯乳液/固化剂种类、比例、稀释剂水添加量等因素对绘画涂料涂层上涂鸦物质清除性能等的影响,并对比测试了涂料的综合性能,制备出了兼具优异涂鸦清除性能、环保性能、耐擦洗性能、施工性能等综合性能优异的水性内墙绘画涂料。经试验测试,涂层表面能够轻松清除水性白板笔、水彩笔、无尘粉笔等涂鸦物质以及鞋油、墨水、番茄酱、咖啡、红茶等多种生活污渍,涂料的组分达到所有相关的环保标准要求,尤其是挥发性有机化合物(VOC)含量仅为11 g/L,远低于T31/01002-C001—2014《儿童水性内墙涂料》标准中VOC的限制20 g/L,特别适合家居儿童房、幼儿园、学校、医院、宾馆等场所的内外墙涂装。Waterborne drawable interior and exterior wall coatings were developed with excellent graffiti removal ability, scrub-resistance and application properties by using waterborne two-component polyurethane and curing agent as film-forming substances. The effect of the binder types and the mixing ratios of waterborne polyurethane and curing agent were discussed, including the dosage of water on the graffiti removal ability of the coatings. The marks of this drawable coatings by a water mark pen, water color pen, dustless chalk, shoe polish, ink, tomato juice, coffee and black tea can be easily cleaned. The compositions in this paint meet the requirements of all the related environment standards. In particular, VOC content is only 11 g/L, which is much lower than the VOC limit 20 g/L in T31/01002-C001—2014 for waterborne interior coatings. This product was environmentally friendly and suitable for kids＇ rooms, kindergarten, schools, hospitals, hotels and public places.
