Problems solved by technology

[0004] At present, in the process of near-net forming of carbon steel, phosphorus saponification is generally used as a lubrication method. This kind of lubrication effect is better, but there are problems such as many processes, difficult cleaning and pollution to the environment. Therefore, it is necessary to find a more ideal Lubrication method for near-net-shape processes

Abstract

The invention relates to a near-net-shaping lubricant and a preparation method thereof. Nano-ZnO, nano-molybdenum disulfide MoS2 and borate are used as extreme pressure agents; sodium polyacrylate, sodium hexametaborate, polyethylene glycol, glycerin and Triethanolamine was used as a dispersant; sodium dodecylbenzenesulfonate and thiadiazole derivative TH‑571 were used as a rust inhibitor. The near net shape lubricant prepared by the invention can be directly used in the near net shape process of complex parts such as gears. The near-net shape lubricant is easy to use and easy to operate. It is non-toxic, non-irritating, odorless, and fume-free during the manufacturing and production process of the near-net shape. The product has good lubricating properties and certain surface repair functions. The lubricant prepared by it The lubricant can improve and replace the traditional near net shape lubricant to a certain extent, and reduce environmental pollution.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a near-net-shape lubricant and a preparation method thereof. Background technique [0002] In actual production, the near net shape mold needs to bear a large load, and in the process of near net shape, there will be alternating friction force and a large number of new surfaces appear on the surface of the deformed metal, so that the metal material adheres The phenomenon of the mold is more serious, which has a great impact on the stable operation of the near net shape mold, and wear has become one of the main ways for the near net shape mold to fail. [0003] Using a reasonable lubricant is an effective measure to reduce friction in near net shape. The lubricant can form a layer of lubricating layer on the surface between the near-net shape mold and the blank, avoiding direct contact between the mold and the blank, greatly reducing the friction coefficient between the two, r...
