摘要:
首先对杜仲胶(EUG)进行环氧化改性得到环氧化EUG(EEUG),然后对EEUG进行湿法接枝二氧化硅(SiO2)制备出EEUG接枝SiO2复合材料(EEUG-g-SiO2),研究了EEUG-g-SiO2复合材料的结构与性能。结果表明,相较于机械共混物EUG/SiO2和EEUG/SiO2,EEUG-g-SiO2硫化胶中纳米SiO2的分散性改善明显,力学性能大幅度提升;与EUG/SiO2硫化胶相比,EEUG-g-SiO2硫化胶的撕裂强度提高了30.9%,耐疲劳性能提升了575.0%,磨耗量降低了94%;与EEUG/SiO2硫化胶相比,EEUG-g-SiO2硫化胶的撕裂强度提高了10.5%,耐疲劳性能提升了68.6%,磨耗量降低了72%,压缩生热明显降低。
Abstract:
Firstly, Eucommia ulmoides gum (EUG) was epoxidized to obtain epoxidized EUG (EEUG). Then, EEUG grafted silicon dioxide (SiO2) composite (EEUG-g-SiO2) was prepared by wet graf-ting SiO2 onto EEUG. The structure and properties of EEUG-g-SiO2 composite were studied. The results showed that compared with EUG/SiO2 and EEUG/SiO2 mechanical blends, the dispersion of nano SiO2 in EEUG-g-SiO2 vulcanizate was significantly improved and the mechanical properties were greatlyimproved. Compared with EUG/SiO2 vulcanizates, the tear strength of EEUG-g-SiO2 vulcanizate increased by 30.9%, fatigue resistance increased by 575%, and abrasion decreased by 94%. Compared with EEUG/SiO2 vulcanizate, the tear strength of EEUG-g-SiO2 vulcanizate increased by 10.5%, fatigue resistance increased by 68.6%, abrasion decreased by 72%, and the compression heat build-up decreased significantly.
