摘要
由于橡胶材料自身的特性不同,对甲醇体积分数不同的甲醇汽油的抗膨胀性存在差异,采用汽车上常见的3种橡胶材料分别在93#汽油和不同甲醇体积分数的甲醇汽油中进行浸泡实验。试验结果表明,硅橡胶在高比例甲醇汽油中抗膨胀性较好,氟橡胶在低比例甲醇汽油中抗膨胀性较好,而丁腈类橡胶在不同比例甲醇汽油中均有很好的抗膨胀性。
Because of inherent characters of rubber materials, there exists some differences on anti-swelling property of rubber materials in gasoline with different methanol volume fraction. Immersion tests in gasoline 93^# or gasoline with different methanol proportions are conducted to show the anti-swelling property of 3 rubber materials commonly used in motor vehicles. The results show that silicone rubber has better anti-swelling property in gasoline with high methanol proportion; on the contrary, fluorine rubber has good resistance to swelling in low- proportion-methanol gasoline; Nitrile Rubber has good anti- swelling property in all gasoline with different proportion of methanol.
