-
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。Abstract: 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.
