| 中文摘要: |
| 采用金属纳米填料（包括纳米钛粉、纳米铜粉和纳米铁粉）与无机纳米填料（包括石墨、纳米二硫化钼、纳米碳纤维、碳纳米管和纳米碳化硼）相结合的方式，开发出适用于橡胶履带的多功能纳米混合填料（简称混合填料），研究混合填料对丁苯橡胶（SBR）复合材料的附着力、拉伸强度、摩擦学性能及耐酸碱溶液腐蚀性能的影响，并分析复合材料的补强、耐磨和耐腐蚀机理。结果表明：随着混合填料用量的增大，SBR复合材料的附着力和拉伸强度先增大后减小，摩擦因数和磨损率先减小后增大，耐硫酸溶液和氢氧化钠溶液腐蚀性能先提高后降低；当每种纳米填料用量均为5份时，SBR复合材料的附着力和拉伸强度最大，耐摩擦磨损性能及耐酸碱溶液腐蚀性能最佳。 |
| 英文摘要: |
| A multi-functional nano mixed filler（referred to as mixed filler） suitable for rubber tracks was developed by combining metal nano fillers（including nano titanium powder，nano copper powder and nano iron powder） with inorganic nano fillers（including graphite，nano molybdenum disulfide，nano carbon fibers，carbon nanotubes and nano boron carbide），the effects of mixed fillers on the adhesion，tensile strength，tribological properties and acid and alkali solution corrosion resistance of styrene butadiene rubber （SBR） composites were studied，and the reinforcement，wear resistance and corrosion resistance mechanisms of the composites were analyzed.The results showed that as the amount of mixed filler increased，the adhesion and tensile strength of SBR composite increased at first and then decreased，while the friction coefficient and wear rate decreased at first and then increased，and the corrosion resistance of sulfuric acid solution and sodium hydroxide solution were improved at first and then reduced.When the amount of each nanofiller was 5 phr，the adhesion and tensile strength of SBR composite were the highest，and the friction and wear resistance as well as acid and alkali solution corrosion resistance were the best. |
