摘　　要：在无溶剂条件下,制备了一种羧基化聚醚有机硅紫外线吸收剂CPE-MUVS。用红外光谱、核磁共振氢谱、紫外光谱对其结构进行了表征。将CPE-MUVS进行乳化得到了透明乳液,用马尔文公司的纳米粒度及Zeta电位仪测出乳液平均粒径为33.08 nm,Zeta电位-41.24 mV。氨基硅乳(ASO-1)/CPE-MUVS复配体系用于棉织物后整理的结果表明,ASO-1/CPE-MUVS能改善棉织物的紫外线吸收性能,并能明显降低棉织物的弯曲刚度,增强棉织物的亲水性,对棉织物的白度无影响。In the absence of solvent, a kind of carboxyl modified polyether organosilicon UV absorber （CPEMUVS）was prepared. The chemical structure of CPE -MUVS was characterized by means of IR,1HNMR and ultraviolet spectrum. CPE - MUVS was subsequently emulsified to obtain the transparent emulsion. It was found that the average diameter and the zeta potential of the emulsion were respectively 33.08 nm and -41.24 mV ,which was measured by the Malvern nanometer particle-size and the zeta potential analyzer. The application study of the compounded system ASO - 1/CPE - MUVS was carried out with cotton fabric. The results indicate that ASO - 1/CPE - MUVS could improve the UV-absorbing performance of the fabric. Meanwhile, CPE - MUVS could obviously decrease the bending stiffness, increase the water-absorbing of the fabric and had no influence on the whiteness of the fabric.
