摘要
利用巯丙基三乙氧基硅烷改性皮革胶原纤维(MCF),并将其作为丁苯橡胶(SBR)的补强剂,以提高丁苯橡胶复合材料的拉伸强度和断裂伸长率。结果表明,基于MCF多尺度结构在增韧中的作用及其与橡胶的界面相互作用,提高了MCF在橡胶中的分散,促进了界面应力传递,从而增强了复合材料的机械性能。与纯SBR相比,填充3%(质量分数)MCF的弹性体复合材料拉伸强度从1.6MPa提高到2.1MPa,断裂伸长率从184%提高到247%。
Leather collagen fiber(MCF)was modified by mercaptopropyl triethoxysilane and used as a reinforcing agent to improve the tensile strength and elongation at break of SBR composites.The results show that the multi-scale structure of MCF enhances the dispersion of MCF in rubber,promotes the interfacial stress transfer,and enhances the mechanical properties of the composites.Compared with pure SBR,the tensile strength of the elastomer composite filled with 3%(mass fraction)MCF is increased from 1.6 MPa to 2.1 MPa,and the elongation at break is increased from 184%to 247%.
