摘要：合成了磷氮型极压抗磨添加剂亚磷酸二丁酯-马来酸二丁酯-胺衍生物(Ⅰ)和亚磷酸二丁酯-丙烯酸酯-胺衍生物(Ⅱ)。研究表明烷基链较长时油溶性好,用伯胺时极压抗磨性好。经比较,Ⅰ中采用十二胺衍生物(Ⅰ-4)时,其极压抗磨性最好(WSD=0.38mm,P_B=1176N,铜片腐蚀结果为1b),它在基础油(750SN)中最佳用量为2%(wt)。用差热分析、红外光谱和俄歇尔电子能谱初步研究表明:磷氮剂(Ⅰ-4)的作用机理是在摩擦表面形成一种含有磷酸铁的化学保护膜。
Two kinds of extreme pressure-antiwear additives of P-N type were synthesized. The one (Ⅰ) is dibutyl phosphite-dibutyl maleate-amine derivative and the other (Ⅱ) is dibutyl phosphite-alkyl acrylate- amine derivative. It was found that they are both well oilsoluble when they possess longer alkyl chain and have well extreme pressure-antiwear property when primary amine is used. By comparison, the dibutyl phosphite-dibutyl maleate-lauryl amine (Ⅰ-4) has the best extreme pressure-antiwear property (WSD=0.38mm, P_B=1176N, copper corrosion=1b). The preferable amount of (Ⅰ-4)in base oi1(750 SN)is 2% (wt). The functional mechanism of (Ⅰ-4) may be the formation of iron phosphate on the wear surface, as proved by DTA, IR, and AES.
