摘    要: 针对目前所用涂料印花黏合剂存在的色牢度低和甲醛含量高的缺陷,采用钴60-γ辐射法聚合工艺,利用丙烯酸酯单体、双丙酮丙烯酰胺(DAAM)合成出含活性酮羰基的丙烯酸酯乳液;然后同含端酰肼基聚氨酯乳液按一定的比例混合,制备出酮肼交联型丙烯酸酯聚氨酯(PUA)复合乳液。通过红外光谱、力学性能和耐水性能检测对该复合乳液进行了分析和表征,并对涂料印花黏合剂的色牢度和环保性能进行检测。结果表明:DAAM的质量分数为1.30%~1.40%时,PUA复合乳液的性能较好,基于该乳液制备的黏合剂为无醛、无APEO的环保型产品;用于织物的涂料印花,其耐刷洗色牢度和耐摩擦色牢度提高,甲醛含量满足婴幼儿服装要求。

Abstract:Aiming at the shortcomings of high formaldehyde content and low soaping and crocking fastnesses of currently used pigment printing binder,by60Co-γ radiation polymerization process,the waterborne polyacrylate(PA) emulsion containing active keto groups was synthesized from acrylate monomers and diacetone acrylamide(DAAM).Then ketone-hydrazide polyurethane-acrylate(PUA) hybrid emulsions were obtained by blending the adipic dihydrazides(ADH) groups-terminated PU emulsion and the PA emulsion according to a given proportion of DAAM and ADH.The mechanical properties and water-resisting properties of PUA hybrid emulsions were studied by means of FT-IR,etc.The colour fastness and environmental protection behavior of the pigment printing binder based on PUA hybrid emulsions were tested.The results showed that the PUA hybrid emulsions provides optimum properties when the contents of DAAM are around 1.30-1.40 percent,and the pigment printing binder is an environmental-friendly product free from formaldehyde and APEO.And the properties of the printed fabrics using the binder such as soaping and crocking fastnesses are excellent,and the formaldehyde content of the printed fabrics can meet the criteria of products for babies.
Keywords:radiation polymerization  emulsion  polyurethane  polyacrylate  ketone-hydrazide crosslinking  pigment printing
