聚丙烯酸酯蓝色乳液的制备及应用

Preparation and application of blue polyacrylate emulsions

用经内交联单体和外交联单体改性后的内外两层丙烯酸酯聚合物对酞菁蓝颜料粒子进行包覆处理,制得蓝色乳液,并将其用于棉织物的涂料染色。结果表明,当聚合反应温度60℃,颜料质量(平均粒径160 nm)占蓝色乳液总质量的5%,单体总质量与颜料质量之比为3∶1,氧化还原引发体系APS-NaHSO(质量比=1.2∶1)3为单体总质量的0.8%,内交联单体N,N-亚甲基双丙烯酰胺为单体总质量的0.5%,外交联单体甲基丙烯酸缩水甘油酯为单体总质量的2.0%时,所得蓝色乳液稳定性高。染色布样的各项色牢度较高,且手感柔软。

A blue emulsion is prepared by encapsulated phthalocyanine blue pigment particles with two- layer acrylate polymers which are modified by intra-crosslinkable monomer and inter-crosslinkable mono- mer, respectively. The pigment dyeing on cotton fabric with the blue emulsion is carried out. The results show that blue emulsion has the best stability, when the reaction temperature is 60 ~C, the mass of pig- ments （average particle size 160 nm） is 5% of total mass of blue emulsion, the mass ratio of all mono- mers to pigment is 3： 1, and the dosage of the intra-crosslinkable monomer N,N＇-methylenebisacryl- amide, inter-crosstinkable monomer glycidyl methacrylate, and redox initiator system APS-NaHSO3 （1.2： 1, mass ratio） are 0.5%, 2.0%, and 0.8% of total mass of monomers, respectively. The color fastness of the dyeings with the blue emulsion is relatively high, and the handle is soft.
