中国石化石油化工科学研究院近日开发出ARE环保型芳烃橡胶填充抽提工艺。该工艺以富含芳烃的溶剂精制油为原料,筛选出对多环芳烃具有选择性溶解能力的抽提溶剂,在中型ARE装置上生产出满足欧盟2005/69/EC指令要求的芳烃橡胶填充油,并建成7万吨/年环保型芳烃橡胶填充油生产装置。溶剂精制抽出油经ARE溶剂抽提可以满足欧盟指令要求,采用该填充油对橡胶充油后得到的橡胶性能优良,各项指标均达到SBR1723优级品要求。 相似文献

简介橡胶油的作用机理,概述环保橡胶油产品的发展状况。环保橡胶油分为经处理芳烃油(TDAE)、环烷烃油(NAP)、浅度溶剂抽提油(MES)、残余芳烃抽提油(RAE)和调合油五大类。TDAE的使用性能较好,应用广泛;芳碳率(C_A)和环烷碳率(C_N)之和不小于55%的NAP与橡胶的相容性较好,应用前景良好;MES的C_A较小,饱和度和生产成本较高;RAE与丁苯橡胶(SBR)相容性较好,价格较低。填充TDAE的SBR1723、填充NAP的SBR1762以及填充RAE的SBR1783均可替代填充芳烃油(DAE)的SBR1712。 相似文献

High aromatic oils which have been widely used as process oils in tire the industry contain high concentrations of polycyclic aromatic hydrocarbons (PAHs). These aromatic compounds (PAHs) have proved to be carcinogenic as well as posing a threat to the environment. Since the beginning of 2010, the use of high aromatic process oils has been banned under the EU regulation 1907/2007 commonly called REACH (registration, evaluation, authorization and restriction of chemicals). The so-called regulation has given rise to challenges to the oil and tire industries in replacing high aromatic process oils with safer alternatives. In the present work, four types of low aromatic petroleum-based process oils, namely mild and high-viscosity naphthenic oils (LNAP and HNAP), treated distillate aromatic extract (TDAE) and mildly extracted solvate (MES), were investigated and their effect on plasticization and durability properties of two different low and high oil-extended tire formulations were evaluated. The compatibility of oils with rubber was investigated as well. The results showed that a number of properties such as abrasion resistance and tire rolling resistance were improved by using non-carcinogenic oils, while tire grip properties were declined. Considering oil–rubber compatibility, TDAE and MES were found to be more compatible with rubbers. 相似文献
