含硅聚丙烯酸酯乳液黏合剂的合成及应用

Synthesis and application of organic silicon modified polyacrylate emulsion adhesive

以乙烯基三甲氧基硅烷(A-171)、甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)和丙烯酸(AA)为聚合单体,以过硫酸钾(KPS)为引发剂,采用半连续种子乳液聚合法合成有机硅-丙烯酸酯织物印花黏合剂,并对其结构进行表征。将乳液应用于纯棉织物涂料印花,研究了工艺条件对印花织物性能的影响。结果表明,在增稠剂2%,黏合剂20%,焙烘温度150℃,焙烘时间3 min时,织物印花效果较佳。印花织物具有良好的耐摩擦色牢度和耐皂洗色牢度,且手感柔软。

Silicone-acrylate printing adhesive is prepared using semi-continuous seed emulsion polymer- ization with ethenyltrimethoxy （A-171）, methyl methacrylate （MMA）, butyl acrylate （BA） and acrylic acid （AA） as the monomers, persulfate （KPS） as the initiator, and its structure is characterized. Then the emul- sion is applied to pigment printing for pure cotton fabric, and the effect of processing conditions on printing properties is studied. The results show that the optimized process is thickening agent 2%, adhesive 20%, and curing at 150℃ for 3 min. The printed fabric has soft handle and good color fastness to rub- bing and soaping.
