摘　　要：将季铵化改性的木质素(QL)和醋酸锌以水热法合成了一种具有花瓣状的QL@ZnO复合材料,以异佛尔酮二异氰酸酯、聚乙二醇1000、2,2-二羟甲基丁酸、分散红60(DR60)、季戊四醇三丙烯酸酯(PETA)和三乙胺为原料合成了光固化型高分子染料(URPD)。将QL@ZnO和URPD复合并通过丝网印花方式涂敷在棉织物上。采用FTIR、GPC、DSC分析了URPD的结构与性能。通过紫外光固化方式得到的QL@Zn O/URPD印花织物具有良好的色牢度(4~5级)。QL和ZnO的协同效应使得QL@Zn O/URPD印花织物的紫外线防护系数(UPF)可达128.49。A petal-like quaternary ammonium modified ligin(QL)@ZnO composite material was prepared from QL and zinc acetate by hydrothermal method.A UV-curable polymer dye(URPD)was synthesized using isophorone diisocyanate,polyethylene glycol,disperse red 60(DR60),2,2-bis(hydroxymethyl)butyric acid,pentaerythritol triacrylate(PTEA)and triethylamine as raw materials.QL@Zn O composite material and URPD were compounded and coated on cotton fabric by screen printing.The structure and properties of URPD were analyzed by FTIR,GPC and DSC.The results showed that QL@ZnO/URPD printed cotton fabric obtained by UV curing technique had good color fastness(4~5 grade).The synergistic effect of QL and ZnO made QL@ZnO/URPD printed cotton fabric had a ultraviolet protection factor(UPF)of 128.49.
