以丙烯酸丁酯和苯乙烯为单体,过硫酸钾为引发剂,通过乳液聚合法对废弃革屑中提取的胶原蛋白进行改性,制备了一种新型的胶原蛋白改性纸张表面施胶剂.以产物接枝率和沉淀率作为考察指标,通过单因素实验对改性胶原蛋白表面施胶剂的制备条件进行优化；采用傅立叶红外光谱仪(FT-IR)、激光粒度仪、透射电子显微镜(TEM)对产物进行表征,并研究其施胶性能.结果表明,胶原蛋白和非离子单体发生了接枝反应,接枝率为65％左右.产物具有球型结构,其微粒形状规整、大小均一,平均粒径为0．117μm.将其作为施胶剂,可使纸张的环压强度和抗张强度分别提高1．5和1．8倍,60 s 吸水值降低了2．8倍,获得较强的抗水性.以废弃革屑中提取的胶原蛋白为原材料,制备造纸施胶剂,不仅促进了皮革固体废弃物的资源化利用,同时将有可能为造纸行业提供一种新型的造纸施胶剂.

The collagen extracted form leather wastes was as raw material,butyl acrylate and styrene was as monomers,and potassium persulfate was as initiator,a collagen-modified surface sizing agent for papers was prepared by emulsion polymerization method.The grafting rate and the precipitation rate of the product were as indexes,the preparation conditions of modified collagen surface sizing agent were optimized by single factor ex-periments.The product was characterized by FT-IR,particle size analyzer and TEM.The sizing performance of the sizing agent was also studied.The results showed that the grafting reaction between collagen and non-ionic monomers was carried out.The grafting rate was about 6 5%.The structure of product was the ball type with the neat shape and uniform size.And the average particle size was about 0.117μm.The sizing agent was used in paper sizing,the ring crush strength and the anti-tensile strength of the papers increased respectively for 1 .5 and 1.8 times.The water-absorbing value of 60 s was decreased for 2.8 times.Papers obtained the stronger water re-sistance.The collagen extracted from leather wastes was as raw material.It has not only accelerates the recy-cling use of solid leather wastes,but also provides likely a novel sizing agent for papermaking industry.
