摘　　要：通过在蓖麻油酸的基础上引入N,B极压吸附基团,合成了具备防锈润滑双功能的蓖麻酰胺硼酸酯液压支架传动介质用BM添加剂,通过四球法和SEM-EDS研究了该添加剂的润滑性能,通过梅花点滴和电化学法研究了该添加剂在浓度为330 mg/L的NaCl溶液中对HT300灰口铸铁的防锈性能。结果表明:质量浓度为0.5%时P_(B)值可达696 N,这是由于吸附膜和化学反应膜共同起到润滑作用;质量浓度为0.5%的BM在盐水介质中对HT300灰口铸铁有良好的防锈作用,这是由于含有较多O,N杂原子,活性吸附位点较多,多个吸附中心使得BM在金属表面形成了致密的保护膜,极化曲线表明为阳极型防锈剂。A ricinamide borate hydraulic support additive(BM) with dual functions of anti-rust and lubrication was synthesized by introducing N and B extreme pressure adsorption groups on the basis of ricinoleic acid.The lubricating properties of the additive were studied by four-ball method and SEMEDS,and the antirust properties of the additive on HT300 gray cast iron in 330 mg/L NaCl solution were studied by plum blossom spotting and electrochemical methods.The results show that the P_(B) value can reach 696 N when the mass concentration is 0.5% because the adsorption film and the chemical reaction film play a lubricating role together.BM with a mass concentration of 0.5% has a good antirust effect on HT300 gray cast iron in saline medium due to the presence of more O and N heteroatoms and more active adsorption sites.Multiple adsorption centers make BM form a dense protective film on the metal surface.The polarization curve shows that it is an anodic rust inhibitor.
