| 研制一种润滑性能较好的水基粘土润滑剂.在MMW-5G摩擦试验机上比较13种粘土材料的干粉摩擦性能,发现水镁石的润滑效果最好,以水镁石为基料,配置成环保水基润滑剂,然后以四球为摩擦副,比较含不同量的聚丙烯酰胺(PAM)、硼酸的该润滑剂的摩擦系数,得到最优配比下PAM、硼酸的浓度分别为1%和5%,摩擦系数相对于空磨降低了85%.关于PAM含量、硼酸含量、粘土种类的三因素三水平的正交试验(L9(34)),验证了单因素的最优配比.参考最优配比,研究不同粘土材料的摩擦性能、该润滑剂在不同载荷、转速下摩擦性能的变化.结果表明:同其他粘土材料相比,该润滑剂的润滑效果较好；随着载荷的增加摩擦系数先减小后增大；随着转速的增加摩擦系数逐渐减小. |

| The paper amis at researching a kind of water-based clay lubricant with good lubricating properties.13 kinds of Clay powder were investigated on MMW-5G friction tester with four-ball friction pair,brucite was chosen as research material to prepare a benign water-based lubricant.According to the friction coefficients of different content of PAM,boric acid,the optimal formula was obtained with 1wt% PAM and 5wt% boric acid,the friction coefficient was reduced by 85% in the presence of lubricant compared with empty friction.The orthogonal experimental design (L9(34)) with PAM content,the boric acid content,clay type verified the optimal ratio of single factor.Based on the optimal formula,varies clay materials,load and speed were changed to make a further study on the friction coefficient.Results showed that the lubricant provided the best lubricating effect in anti-friction than other clay minerals;With the increasing of the load,the friction coefficient decreases first and then increases,but decreases with increasing road speeding. |
