摘要
聚合物分散剂主要通过锚定基团吸附在颜料表面而起到稳定作用,锚定基团含量会影响到分散剂的吸附效果,进一步影响到颜料的稳定.本文采用溶液聚合法以苯乙烯和端羟基聚乙二醇甲基丙烯酸酯(HO-PEG-MA)为原料,通过改变两者的加入比例来制备不同含量苯基为锚定基团的聚合物分散剂,用于有机颜料紫23的分散稳定,并对研磨后色浆的粒径、吸附量、储存稳定性等进行了测试.结果表明,苯乙烯和端羟基聚乙二醇甲基丙烯酸酯加入的摩尔比为3∶1时,稳定效果最好,研磨后粒径可达到为191.3 nm,且储存稳定效果好.
Abstract
The anchor group of polymeric dispersants absorbed onto the pigment surface,aiding in improving the stability of the pigment suspension.The content of anchoring groups affects the adsorption effectiveness of the dispersant and the stability of the pigment.In this study,a series of polymeric dispersants with varying contents of anchoring group were prepared via solution polymerization,using different additions of styrene and hydroxy polyethylene glycol methacrylate(HO-PEG-MA).These dispersants were employed for the dispersion of pigment violet 23.The particle size,storage stability,and surface adsorption capacity of pigment suspension were characterized.When the molar ratio of styrene to hydroxy polyethylene glycol methacrylate was 3∶1,the particle size of pigment suspension was 191.3 nm and the stability of pigment suspension was optimal.
