摘要
以四乙烯五胺、甲醇和丙烯酸甲酯为原料,通过四乙烯五胺和丙烯酸甲酯之间的缩聚反应合成了具有超支化结构的化合物HBP。采用红外光谱FTIR、紫外-可见光吸收光谱UV-vis对超支化聚合物进行了表征,研究了超支化聚合物的制备机理。进一步配制了超支化聚合物HBP的水溶液,采用浸渍的方法对水刺非织造布进行后整理。对整理前后水刺非织造布的基本性能进行测试,结果表明采用HBP水溶液成功浸渍了水刺非织造布,说明水刺非织造布和超支化聚合物有着较好的亲和力,并且该整理方法不会造成非织造布强力的损失,经过整理后的水刺非织造布的吸湿性能有所提高。
By using tetraethylenepentamine,methanol and methyl acrylate as raw materials,the compound HBP with hyperbranched structure was synthesized by the condensation reaction between tetraethylenepentamine and methyl acrylate. The hyperbranched polymer HBP was characterized by the Infrared spectroscopy（ FTIR） and UV-visible absorption spectra（ UV-vis） and the preparation mechanism of the hyperbranched polymer was studied. The aqueous solution of hyperbranched polymer HBP was further prepared,and the spun-lace non-woven fabric was conducted after-finishing by dipping method. The basic performance of the pre/after-finishing spunlace non-woven fabric was tested. The results showed that the use of HBP aqueous solution successfully impregnated the spun-lace non-woven fabric,which meant the spun-lace non-woven fabric and hyperbranched polymer had good affinity,the finishing process did not decrease the strength of the non-woven fabric and the hygroscopic property of the spun-lace non-woven fabric increased after finishing.
