摘要
以中海油绥中36–1环烷基原油为原料,通过常减压蒸馏工艺和高压加氢工艺技术,研制出了符合HG/T 5085—2016化工行业标准的橡胶增塑剂海疆N4006和N4010基础油,油品具有优异的紫外光安定性和热稳定性,适合用作SBS类苯乙烯热塑性弹性体的填充油。研究了两种油品填充的SBS体系的力学性能,耐热性能以及耐紫外光老化性能,并通过红外光谱分析研究了充油体系的老化机理。结果表明充油体系的力学性能良好:拉伸强度>10 MPa、断裂伸长率>900%,耐光热老化性能优异,热老化后的强度保留率>90%,24 h紫外老化后的强度保留率>60%。经紫外光辐照试样表面的红外图谱在3 300、1 720和1 170 cm–1附近出峰,显示老化降解后新增基团主要为羧酸类和脂肪族酯类。热氧老化后充油SBS试样的红外光谱与未老化试样的无差别,表明其优异的耐热氧老化性能。
Using Suizhong 36-1 naphthenic crude oil as raw material, rubber plasticizer Coastal N4006 and N4010 base oil, conforming to the standard of chemical industry standard(tentative), were developed through vacuum distillation process and high-pressure hydrogenation technology The heat and UV resistant mechanical performance of the Coastal N4006/N4010 oil extended SBS system were investigated, and its aging mechanism was studied by FTIR analysis. The SBS/oil blends showed favorable mechanical properties with an over 10 MPa tensile strength and an over 900% elongation at break, remained high tensile strength after thermo oxidative(over 90%) and UV aging for 24 h(over 60%). The FTIR absorption peaks appeared around 3 300、1 720 and 1 170 cm–1 after UV irradiation, indicating that the main newly increased groups after aging and degradation were carboxylic acid and aliphatic ester groups. The FTIR spectroscopy of samples after thermo-oxidative aging remained the same with the unaged ones, which again proved the excellent thermal stability.
