Abstract
本申请属于材料领域，具体公开了一种丙烯酸系粉体增稠剂的制备方法及产品。所述制备方法包括：将丙烯酸类单体的水溶液与丙烯酸酯类单体的有机溶液混合，充分反应并干燥研磨，获得所述丙烯酸系粉体增稠剂，所述丙烯酸类单体的水溶液包括质量比为(3～10):(24～40):60的水溶性高分子分散剂、烯丙基聚氧乙烯醚以及丙烯酸类单体。本申请通过采用分子设计和与水溶性高分子分散剂部分代替乳化剂的方法将烯丙基聚氧乙烯醚的亲水链段引入增稠剂分子链中，使得增稠剂可以快速吸收水分，使得羧基离子化，从而提高其开糊效率；经验证，丙烯酸系粉体增稠剂粘度约提高了16％，PVI值约提高了69％，糊化时间缩短了一半。
