Problems solved by technology

Although the phosphating film technology is very mature and stable, there are still many problems that are difficult to improve, such as a large amount of harmful metals such as lead and cadmium in the treatment solution and process waste water treatment, and the treatment cost of rough phosphating film is very high. The cost of forgings is high and difficult, and zinc phosphate may cause surface corrosion on cold forgings

Abstract

The invention discloses a lubricant for cold forging and cold extruding and a preparation method and a using method thereof. The lubricant comprises distilled water, sodium carboxymethylcellulose, sodium polyacrylate, polymethacrylate, mica powder, talc powder, boron nitride, zinc stearate, sodium stearate, alkyl sodium sulfonate, diglycol, triethanolamine, polyvinylpyrrolidone, vinyl triethoxy silane, polyisobutene, polyethylene glycol, nonyl phenol polyoxyethylene ether, an ethylene-vinyl acetate copolymer, an alkaline silica sol, sodium silicate, a styrene-acrylic emulsion, oxalate, vulcanized fat, alkylated aromatic amine and sodium methylenedinaphthalene. The lubricant disclosed by the invention can adsorb a uniform plastic film formed on the surface of a workpiece, so that the workpiece and a mold are isolated by the lubricating film all the way, and the lubricant is good in environmental friendliness and convenient to use, can replace a phosphorizing-saponifying treatment process, and is a non-graphite high molecular lubricant suitable for cold forging and cold extruding forming of metals or nonferrous metals.

Description

technical field [0001] The invention relates to the technical field of cold forging and cold extrusion lubrication, in particular to a lubricant for cold forging and cold extrusion, a preparation method and a use method. Background technique [0002] Cold forging, cold extrusion, and cold pier are forming processes for blanks at room temperature. They have a series of advantages such as material saving, high product precision, low roughness, reduced cutting, high product strength indicators, and high production efficiency. Cold forging, The success of the cold extrusion process depends largely on the correct use of lubricants, which are divided into two types: mold lubrication and billet surface lubrication. [0003] At present, the cold forging and cold extrusion processes usually adopt the phosphating-saponification process, which is a combined lubrication process that combines phosphate coating (film) with metal soap, fatty acid, molybdenum disulfide, and organic polymer ...
