摘　　要：考察了以聚丙烯(PP)为基础材料的新型多孔非金属阻隔防爆材料在M45甲醇汽油中恒温浸泡一段时间后,材料受腐蚀的情况及其对甲醇汽油油品性能的影响。采用浸泡法,将材料密封浸泡在M45甲醇汽油中,在70℃下恒温水浴16周。采用定期称重的方法考察材料的失重情况;采用GC-MS对试验前后M45甲醇汽油的酸值、辛烷值进行测试分析,测定汽油的胶质、诱导期等重要参数,以此评价材料对油品品质的影响。结果表明:试验过程中,聚丙烯阻隔防爆材料在M45甲醇汽油发生有限溶胀,材料吸收汽油后受到轻微腐蚀;M45甲醇汽油的酸值和色度发生明显变化,诱导期、胶质和机械杂质等变化较小。The corrosion of a new type of porous non-metallic barrier explosion-proof material based on polypropylene(PP)and its influence on the properties of methanol gasoline oil were investigated after immersion in M45 methanol gasoline for a period of time.The material was sealed and soaked in M45 methanol gasoline by immersion method,then keep the material in constant temperature water bath at 70℃for 16 weeks.The weight loss of the material was investigated by weighing regularly,the acid value and octane number of M45 methanol gasoline before and after the test were tested and analyzed by GC-MS,and the important parameters such as gum and induction period were determined to evaluate the influence of materials on the quality of oil.The results showed that the polypropylene barrier explosion-proof material has limited swelling in M45 methanol gasoline and slightly corroded after absorbing gasoline;The acid value and color of M45 methanol gasoline changed significantly,however the induction period,gum and mechanical impurities changed little.
