摘　　要：以甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)、丙烯酸(AA)和丙烯酰胺(AM)为共聚单体,通过水乳液聚合制备一种四元共聚物(PBMAA)乳液并自然干燥成膜,然后对芳纶Kevlar-1313(K-1313)共聚物进行改性,得到改性共聚物(K-PBMAA),并优化其添加比例以期提高涂饰膜的强度和耐磨损性能。将制备的实心纳米二氧化硅(记为S-SiO_(2))和中空纳米二氧化硅(记为H-SiO_(2))分别添加到K-PBMAA中制备纳米复合皮革涂饰剂(记为S-SiO_(2)/K-PMBAA和H-SiO_(2)/K-PMBAA)并用于绵羊皮的涂饰,发现K-1313和纳米SiO_(2)的同时引入使得复合涂膜的最大热分解温度由404℃提升至411℃,力学性能由4.03 MPa提高到8.67 MPa。A quaternary copolymer water emulsion(denoted as PBMAA)and its natural drying film are firstly obtained with methyl methacrylate(MMA),butyl acrylate(BA),acrylic acid(AA)and acrylamide(AM)as monomers.Then,Kevlar-1313 of aramid(denoted as K-1313)is added to modify the copolymer(denoted as K-PBMAA)and the adding ratio is optimized in order to improve the strength and wear resistance of this film.The prepared solid nano-SiO_(2)(denoted as S-SiO_(2))and hollow nano-SiO_(2)(denoted as H-SiO_(2))are also added into K-PBMAA respectively to prepare nanocomposite leather finishing agents(denoted as S-SiO_(2)/K-PBMAA and H-SiO_(2)/K-PBMAA)that are applied for finishing sheepskin.It is found that the thermal decomposition temperature of the coating increases from 404℃to 411℃and the mechanical properties increases from 4.03 MPa to 8.67 MPa when K-1313 and nano-SiO_(2) are introduced at the same time.
