橡胶产品中橡胶助剂的分析有重要现实意义.由于橡胶产品中添加的助剂种类较多,添加量差别较大,部分助刺又已发生反应,因此进行橡胶助剂的全分析是一项有较高难度的工作.通过中压色谱分离,红外光谱定性的方法,鉴定了乙丙橡胶助剂中的矿物油、邻苯二甲酸酯、植物油等3种软化剂,以及残余的硫化促进剂M和防老化剂苯乙烯化苯酚;采用同相萃取去除助剂中主量成分矿物油,以减少对其他少量助剂成分的干扰,通过气质联用法,推测出橡胶助剂中的2,6-二叔丁基-4-甲基苯酚防老剂、残余的秋兰姆类硫化促进剂,同时利用气质联用仪,直接测定乙丙橡胶抽提液,鉴定了残余的活泼性物质过氧化苯甲酰类硫化剂.文章研究结果可供其他橡胶体系有机助剂全分析的借鉴.

In the present paper,after middle pressure chromatograph separation using both positive phase and reversed-phase conditions,the organic additives in ethylene-propylene rubber were identified by infrared spectrometer.At the same time,by using solid phase extraction column to maintain the main component-fuel oil in organic additves to avoid its interfering with minor compounds,other organic additves were separated and analysed by GC/Ms.In addition,the remaining active compound such as benzoyl peroxide was identified by CC/Ms,through analyzing acetone extract directly.Using the above mentioned techniques,soften agents (fuel oil,plant oil and phthalte),curing agent (benzoylperoxide),vulcanizing accelerators (2-mercaptobenzothiazole,ethyl thiuram and butyl thiuram),and antiagers (2,6-Di-tert-butyb4-methyl phcnol and styrenated phenol) in ethylenepropylene rubber were identified.Although the technique was established in ethylene-propylene rubber system,it can be used in other rubber system.
