摘　　要：以水性树脂、消光粉和其他助剂为原料,通过配方优化改进,制备了一种抗压抗污渍高硬度的水性清面漆。探讨了不同水性丙烯酸树脂与水性聚氨酯树脂的复配筛选及其配比、不同的成膜助剂和消光粉的种类对最终研制的水性全亚光(光泽为2%~5%)高硬度抗压抗污渍清面漆的硬度、抗压性能、抗污渍性和透明度的影响。按照GB/T 6739-2006《色漆和清漆铅笔法测定漆膜硬度》标准进行测试,对涂膜的硬度进行评估。结果表明:当配方采用水性树脂7515与2593[复配比例m(7515)∶m(2593)=3∶1]、成膜助剂DE、消光粉P260DS时,搭配质量分数1%的增强剂(氮吡啶),最终开发的水性高硬度抗压抗污渍清面漆的涂膜抗压性能、硬度表现和抗污渍均达到最佳,其中铅笔硬度等级达到F。Using waterborne resin,matting powder and other additives as raw materials,through formula optimization and improvement,a waterborne clear topcoat with high hardness,pressure resistance and stain resistance was prepared.The compound screening and proportion of different waterborne acrylic resins and waterborne polyurethane resins,as well as the effects of different film-forming additives and matting powder types on the hardness,pressure resistance,stain resistance and transparency of the finally developed waterborne fully matte(gloss of 2%~5%)high-hardness anti-pressure and anti-stain clear topcoat were discussed.The test was carried out in accordance with the standard GB/T 6739—2006 Determination of Paint Film Hardness by Pencil Method for Paints and Varnishes to evaluate the hardness of the coatings film.The results show that when the formula uses waterborne resins 7515 and 2593[compound ratio m(7515)∶m(2593)=3∶1],film-forming additive DE,matting powder P260DS,and 1%enhancer(azopyridine),the finally developed waterborne high-hardness anti-pressure and anti-stain clear topcoat has the best pressure resistance,hardness performance and stain resistance,and the pencil hardness grade reaches F.
