摘　　要：通过引入自制的单丙烯酸酯聚二甲基硅氧烷功能单体,采用乳液聚合法制备出高硅元素含量和低玻璃化转变温度(Tg)的柔性硅丙乳液。采用红外光谱、X射线光电子能谱和差示扫描量热仪研究了柔性硅丙乳液的化学结构,通过扫描电镜观察了柔性硅丙乳液涂料印花织物的表面形貌。结果表明:自制的柔性硅丙乳液胶膜具有较高的表面和截面硅元素质量分数(分别为26.4%和17.51%)、较低的Tg(-38.76℃)和较低的48h吸水率(16.75%)。当印花色浆中柔性硅丙乳液质量分数为10%时,涂料印花织物的耐干/湿摩擦色牢度可达4级,手感柔软度优异。Flexible silicone-acrylic emulsion with high silicon content and low glass transition temperature(Tg)are prepared by emulsion polymerization through the introduction of selfmade monoacrylate polydimethylsiloxane functional monomer.The chemical structure of the flexible silicone-acrylic emulsion is investigated by infrared spectroscopy,X-ray photoelectron spectroscopy and differential scanning calorimetry,and the surface morphology of the flexible silicone-acrylic emulsion pigment printed fabrics is observed by scanning electron microscopy.The results show that the flexible silicone-acrylic emulsion film has high silicon contents(26.4% and 17.51%,respectively)at surface and cross-section,low Tg(-38.76℃),and low water absorption at 48 h(16.75%).When the dosage of flexible silicone-acrylic emulsion in printing color paste is 10%,the color fastness to dry/wet friction of pigment printed fabrics can reach Grade 4,and the hand softness is excellent.
