润滑脂用高碱值烷基苯磺酸钙的研究

Six kinds of alkylbenzene sulfonic acids were selected to prepare the sulfonates S1—S6. Among them, the sulfonates S3, S4, and S6 could be incorporated into lubricating grease with good performance in comparison with the grease produced from commercial sulfonates T106-1 and T106-2. The optimized conditions for synthesis of the sulfonates S3, S4, and S6 were explored by using different mass ratios of methanol, water and the type of copromoters. It was found out that the appropriate conditions for synthesis of the sulfonate S3 included a methanol to M(M is the total mass of alkylbenzene sulfonic acid and base oil) mass ratio of 16%, a water to M mass ratio of 4%, and a copromoter A to M mass ratio of 2%; the appropriate conditions for synthesis of the sulfonate S4 included a methanol to M mass ratio of 24%, a water to M mass ratio of 2%, a copromoter B to M mass ratio of 2%; and the optimized conditions for synthesis of the sulfonate S6 included a methanol/ M mass ratio of 8%, a water/M mass ratio of 4% and a copromoter B/M mass ratio of 2%. The new sulfonates S3, S4, and S6 produced under the optimized conditions exhibited higher TBN and better antiwear property in camparison with the previous products. Grease samples G9, G10, and G11 were prepared with new sulfonates S3, S4, and S6 successfully and exhibited improved water stability and high temperature performance.

硼酸、磷酸对改善复合钙基润滑脂硬化现象的机理探讨

In the 1950’s, complex calcium lubricating grease had been widely used. However, due to the hardening problem in the process of storage and use, the production of complex calcium lubricating grease decreases year by year. Domestic and foreign researchers have done a lot of work on its hardening problem, and it has been found that boric acid and phosphoric acid can effectively improve the hardening problem. In this paper, the water absorption test of several calcium salts was carried out, and it was found that calcium 12-hydroxystearate did not absorb water, and calcium acetate, calcium phosphate and calcium borate had different degrees of water absorption. Calcium acetate has the highest water absorption rate, and calcium phosphate and calcium borate have comparable water absorption rates. Using molecular simulation technology, it is found that in the complex calcium grease system, calcium phosphate and calcium borate prefers to combine with water, which inhibits the water absorption of calcium acetate and makes the hardening problem better.
