聚丙烯酸酯无皂乳液粘合剂的合成及应用

The synthesis and application of soap-free emulsion binder on printing

将聚丙烯酸酯无皂乳液粘合剂采用涂料轧染的方法应用于织物的涂料染色.分析了影响织物性能的因素,通过改变粘合剂用量、功能单体用量、焙烘温度和时间等,确定了优化工艺:当甲基丙烯酸(MAA)用量为10%(对单体总质量),丙烯酸羟乙酯(HEA)用量为3.0%(对单体总质量),软单体丙烯酸丁酯(BA)与硬单体甲基丙烯酸甲酯(MMA)质量比[即m(BA)∶m(MMA)]为7∶3时,可以得到最佳粘合剂.选择涂料染色工艺为:织物浸轧染液(室温,粘合剂40 g/L,二浸二轧,轧余率70%)→预烘(80℃,3 min)→焙烘(150℃,3 min).

Through the pigment pad dyeing, polyacrylate soap-free emulsion binder was applied in pigment dyeing of fabric. The factors influencing the properties of fabrics were analyzed, such as dosage of binder and functional monomers, curing temperature and time. Accordingly, the optimal binder could be obtained under the determined optimum process： 10%（on the weight of total monomers） of methacrylic acid （MAA）, 3%（on the weight of total monomers） of hydroxyethyl acrylate （HEA）, the mass ratio of soft monomer butyl acrylate （BA） and hard monomer methyl methacrylate （MMA）, i.e. m（BA）：m（MMA） was 7：3. The pigment dyeing process was： the fabric was dipped and padded （at room temperature, 40 g/L of binder, two dip two pad, 70% of pick up） → dry （80 ℃,3 min）→cure （ 150℃,3 min）.
