GMA改性聚丙烯酸酯黏合剂的应用

为了改善涂料印花织物的手感和牢度,探讨用半连续种子乳液聚合的甲基丙烯酸环氧丙酯(GMA)改性的聚丙烯酸酯黏合剂在涂料印花中的应用。研究分析黏合剂用量、黏合剂pH值、焙烘温度和焙烘时间等因素对涂料印花织物干湿摩擦牢度、表观得色量和印花织物手感的影响。结果表明:该黏合剂获得较佳印花效果的应用工艺是其用量为10%,pH值范围为7~8,焙烘温度为150℃,焙烘时间为3 min;与国内外同类产品相比,GMA改性的聚丙烯酸酯黏合剂更能有效增加印花织物的表观得色量,且印花后织物的手感良好。

Application of glycidyl methacrylate modified polyacrylate binder

A glycidyl methacrylate(GMA)modified polyacrylate binder for pigment printing,which was synthesized by seeded semi-continuous emulsion polymerization,was applied to improve the handle and fastness of printed textile.The effects of dosage of binder,pH value and baking temperature and time on dry and wet rubbing fastness,color strength(expressed as(K/S) value) and the handle of pigment printed goods were studied and analyzed.And The results indicate that better printing effect can be obtained with this product when the dosage of this binder is about 10% of printing pastes,the range of pH value in 7-8,the baking at(150 ℃) for(3 min.) Compared with other homemade or imported similar products,the GMA modified acrylate binder can enhance more the color strength of printed goods and give softer handle.
