离子液体改性氧化石墨烯／丁苯橡胶复合材料的热降解动力学

为了提高氧化石墨烯（GO）在丁苯橡胶（SBR）中的分散性，采用离子液体氯化1-烯丙基-3-甲基咪唑（AMIMCI）对GO进行改性。得到了离子液体改性GO（GO-IL）。通过乳液混合法制备了GO-IL／SBR复合材料，研究了GO-IL／SBR硫化胶的热稳定性，并分别采用Kissinger法和Flynne-walle-Ozawa法计算了该硫化胶的热降解活化能。结果表明，与未改性的GO相比，GO-IL能明显提高SBR硫化胶的热稳定性；当填料用量为5份（质量）时，GO-IL／SBR硫化胶的最大热失重温度和热降解活化能比GO／SBR硫化胶分别提高了4．0℃和17．35kJ／mol。...

Summary:为了提高氧化石墨烯（GO）在丁苯橡胶（SBR）中的分散性，采用离子液体氯化1-烯丙基-3-甲基咪唑（AMIMCI）对GO进行改性。得到了离子液体改性GO（GO-IL）。通过乳液混合法制备了GO-IL／SBR复合材料，研究了GO-IL／SBR硫化胶的热稳定性，并分别采用Kissinger法和Flynne-walle-Ozawa法计算了该硫化胶的热降解活化能。结果表明，与未改性的GO相比，GO-IL能明显提高SBR硫化胶的热稳定性；当填料用量为5份（质量）时，GO-IL／SBR硫化胶的最大热失重温度和热降解活化能比GO／SBR硫化胶分别提高了4．0℃和17．35kJ／mol。
Bibliography:In order to improve the dispersion of graphene oxide （GO） in styrene-butadiene rubber （SBR） matrix, ionic liquid 1-allyl-3-methylimidazo- lium chloride （AMIMC1） was used to modify GO, and the obtained filler, ionic liquid modified GO （GO-IL） , was emulsion blended with SBR to pre- pare GO-IL/SBR composite. The thermal stability of GO-IL/SBR vulcanizate was investigated, and their thermal decomposition activation energy was ealcu- lated by Kissinger and Flynne-Walle-Ozawa me-thods, respectively. The results showed that GO-IL significantly improved the thermal stability of SBR vulcanizate compared with unmodified GO. When the filler was 5 phr, the maximum thermal mass loss temperature and the thermal decomposition activation energy of GO-IL/SBR vulcanizate increased by 4.0℃ and 17, 35 kJ/mol compared with those of GO/SBR vulcanizate separately.
