| 高分子量新型的润湿分散剂 。高分子表面活性剂一般是指分子质量在数千以上的具有表面活性的高分子化合物。目前涂料工艺中使用的主要有两大类：聚氨酯类和丙烯酸酯共聚物类。 High molecular weight new type of wetting and dispersing agent high molecular surfactant generally refers to the high molecular compound with surface activity whose molecular weight is more than thousands. At present, there are two main categories used in coating process: polyurethane and acrylate copolymer. 聚氨酯类是指以聚氨酯甲酸酯为骨架，嵌接上颜料亲和基团，也叫颜料锚定基。 Polyurethane refers to polyurethane formate as the skeleton, embedded with pigment affinity group, also known as pigment anchor group. 聚丙烯酸酯类是指以聚丙烯酸酯为骨架再接上颜料亲和基团。 Polyacrylates refer to those with polyacrylates as the framework and then pigment affinity groups. 高分子量润湿分散剂特别适用于有机颜料和碳黑，对无机颜料也有效。高分子润湿分散剂吸附基团多，能够牢固地锚定在颜料的表面上，伸展链节长，形成的吸附层比较厚，空间位阻效应强，制成的颜料分散体稳定性好。 High molecular weight wetting dispersant is especially suitable for organic pigments and carbon black, and also for inorganic pigments. The polymer wetting dispersant has many adsorption groups, can be firmly anchored on the surface of pigment, has long extension chain, thick adsorption layer, strong steric resistance effect and good stability of pigment dispersion. |
