Development and Production of Rubber Plasticizer Naphthenic Mineral Oil from Chunfeng Distillate Oil
In order to develop and produce high-quality rubber plasticizer naphthenic mineral oil to meet market demand,Sinopec Jingmen Company used Chunfeng oil with naphthenic characteristics and existing lubricating oil production units,to process Chunfeng distillate through the combination of hydrodeacidification,high-pressure hydrotreating,hydroisomerization and hydrorefining.The results showed that the rubber plasticizer produced by this process had high ω(CN),and its ultraviolet absorbance(260～420 nm)was less than 0.1,and passed the carbonization substances test.The oil was filled into SBS rubber at mass fraction of 33%.It showed that the mechanical properties of the rubber were good and the yellowness was 3.17,which met the requirements of customers.
