摘　　要：利用双辊开炼机将胶原蛋白肽加入硅橡胶中,制备胶原蛋白肽/硅橡胶复合材料。结果表明:胶原蛋白肽在复合材料中有结构控制剂和延迟硫化的作用;随着胶原蛋白肽用量的增加,复合材料的硬度增加,100%定伸应力从1.92 MPa增至2.66 MPa;拉伸强度和撕裂强度降低。当复合材料中胶原蛋白肽含量为4份时,复合材料的最大热失重速率温度比纯硅橡胶降低1.6%,说明加入胶原蛋白肽,降低了复合材料热稳定性;复合材料红外光谱中出现了硅橡胶和胶原蛋白肽的特征峰;接触角比纯硅橡胶降低了4.5%,说明复合材料的亲水性有一定改善。Collagen peptide/Methyl vinyl silicone rubber(MVQ)composites were prepared by adding biomaterial collagen peptide to MVQ using double-roller mill.The results showed that collagen peptide had the effects of structure control agent and delayed vulcanization.With the increasing of the amount of collagen peptide,the composite’s hardness increased,and the 100%tensile stress was improved from 1.92 MPa to 2.66 MPa,but its tensile strength and tear strength decreased.When the collagen peptide content was 4 per hundred of rubber,the maximum thermal weight loss rate temperature of the composite was 1.6%lower than that of MVQ.The characteristic peaks of MVQ and collagen peptide appeared in the infrared spectrum of the composites,and the hydrophilicity had been improved to a certain extent.The contact angle decreased by 4.5%at 4 per hundred of rubber.
