摘要
以N-甲基吡咯烷酮和糠醛为溶剂,对新疆混合原油的减压馏分油进行了精制,并对此抽出油进行注水、降温沉降研究及芳香烃型橡胶填充油的放大制备试验研究。结果表明,在沉降温度50℃、注水量2%、沉降时间40 m in的优化工艺条件下,可使抽出油芳香烃质量分数达到80%以上。以此芳香烃型橡胶填充油进行丁苯橡胶的充油试验,其充油丁苯橡胶主要性能良好,300%定伸应力、拉伸强度及扯断伸长率等性能更为优异。
A process for the production of aromatic rubber extending oil was studied by N-methyl pyrrolidone or furfural solvent extraction of vacuum gas oil obtained from Xinjiang mixed crude oil. In the solvent extraction of lubricating base stocks, the aromatic hydrocarbon content of the extract oil increased with the increase of amount of adding water and decrease of the temperature of the sedimentation process. The results indicated that the mass fraction of aromatic hydrocarbon of the rubber extending oil was up to 80. 0% at the conditions of sedimentation temperature 50 ℃, adding water 2% and sedimentation time 40 min. The results of oil filled test of styrene-butadiene rubber (SBR) by aromatic rubber extending oil showed that the oil extending SBR had good properties, especially the performance of modulus at 300%, the tensile strength and the elongation at break.
