环保橡胶增塑剂A1220的开发及应用

DEVELOPMENT AND APPLICATION OF ENVIRONMENT-FRIENDLY RUBBER PLASTICIZER A1220

以环烷基减压馏分油为原料,采用加氢脱酸-糠醛精制组合工艺,制备环保型橡胶增塑剂A1220,并对其在丁苯橡胶及子午线轮胎胎面胶中应用性能进行评价。结果表明:A1220的各项指标满足GB/T 33322—2016质量要求,用其制备的充油丁苯橡胶SBR1763与传统丁苯橡胶SBR1712的指标相近,满足丁苯橡胶优级品的质量要求;A1220在子午线轮胎胎面胶中应用良好,各项指标与国外环保橡胶增塑剂产品相近,其应用性能满足子午线轮胎胎面胶要求。

The environment-friendly rubber plasticizer A1220 derived from vacuum distillates of naphthenic base was prepared through hydrodeacidification-furfural refining combined process,and its application performance in SBR and radial tire tread rubber was evaluated.The results showed that the rubber plasticizer A1220 prepared met the requirements of national specification GB/T 33322—2016,and the index of SBR1763 filled with rubber plasticizer A1220 was similar to that of traditional SBR1712,which met the quality requirements of SBR superior grade.The rubber plasticizer A1220 was applied well in radial tire tread rubber and the indexes were similar to foreign TDAE products.The application performance of rubber plasticizer A1220 met the requirements of radial tire tread rubber.
