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 forming lubricant and a preparation method thereof. Nano-ZnO, nanometer molybdenum disulfide (MoS2) and borate are used as extreme pressure agents; sodium polyacrylate, sodium hexametaborate, polyethylene glycol, glycerol and triethanolamine are used as dispersing agents; and sodium dodecyl benzene sulfonate and a thiadiazole derivative TH-571 are used as antirust agents. The near-net forming lubricant prepared in the invention can be directly applied to the near-net forming process of complex parts such as gears. The near-net forming lubricant is simple touse and convenient to operate, is free of toxicity, pungent smell and lampblack in the manufacturing and production process of near-net forming, and has a good lubricating performance and a certain surface repairing function, and The near-net forming lubricant prepared in the invention can improve and replace traditional near-net forming lubricants to a certain extent, and reduces 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...
