摘　　要：以克拉玛依高压加氢环烷基橡胶油KN4010为原料,采用折射指数法、紫外分光光度法、薄层包谱和气相色谱-质谱联用等方法,系统地研究了橡胶油在紫外光照射条件下所发生的物理性质和化学组成的变化。研究结果表明,高压加氢环烷基橡胶油在紫外光照射下透光率的变化趋势是一个能较好评价其光安定性的物理指标;且芳香烃和胶质的组成变化是影响其颜色安定性的最主要原因。With the use of KN4010 (Kelamayi high pressure hydro-treated naphthenic rubber oil) as base stock, this paper took use of various characterizing methods including RI, UV, TLC and GC-MS etc to research the change of physical properties and chemical composition under UV radiation. The results not only showed that transmittancy is the most appropriate physical property for the evaluation of light stability of hydro treated naphthenic rubber oil under UV radiation, but also confirmed that aromatics and gums are the main causes effecting on color stability.
