Washable stamping and drawing oil

Abstract

The invention discloses washable stamping and drawing oil. The washable stamping and drawing oil is prepared from the following components in percentage by weight: 10 to 15 percent of base oil 150SN, 5 to 10 percent of high-viscosity self-emulsified ester, 3 to 5 percent of vulcanized aliphatic acid ester, 1 to 3 percent of sulfurized olefin, 30 to 40 percent of chlorinated paraffin, 1 to 5 percent of phosphate, 1 to 5 percent of calcium petroleum sulfonate, 5 to 15 percent of sodium petroleum sulfonate, 1 to 5 percent of tall oil fatty acid, 1 to 5 percent of iso-tridecanol polyoxyethylene ether, 1 to 5 percent of organic alcohol ether, 1 to 5 percent of pH buffering agent and 1 percent of corrosion inhibitor. The performance of the washable stamping and drawing oil disclosed by the invention can completely meet the service demand of a stamping and drawing process; the washable stamping and drawing oil can successfully replace the current pure oil type stamping and drawing oil and is easy to clean.

Description

technical field [0001] This invention relates to water washable stamping and drawing oils. Background technique [0002] Metal processing includes cutting and stamping stretching, etc. Compared with cutting, stretched products have better mechanical properties, so stamping stretching is often used on some metal products with high load requirements, such as body stamping, pipe bending , diameter expansion, oil pan stretching, etc., and the stamping and stretching process has the characteristics of one-time forming, fast speed, and high efficiency. In the process of heavy-duty stamping and drawing, medium-high viscosity lubricating medium is required to isolate the mold and workpiece, prevent the mold from being damaged, and improve the success rate of workpiece drawing. The current heavy-duty stamping and drawing oil is mostly made of mineral-based base oil, added with extreme pressure anti-wear agents such as chlorine-based, sulfur-based, and phosphorus-based, and supplemen...

AI Technical Summary

Problems solved by technology

The current heavy-duty stamping and drawing oil is mostly made of mineral-based base oil, added with extreme pressure anti-wear agents such as chlorine-based, sulfur-based, and phosphorus-based, and supplemented with ester lubricants and some tackifiers. This type of product It can play a very good effect in the stamping and stretching process, but because its kinematic viscosity at 40°C is mostly above 30c, and the higher viscosity can reach several thousand, it is difficult to clean and remove the residue on the workpiece after processing. Using a large amount of hydrocarbon solvents and supplemented by equipment such as heating and ultrasonic cleaning is a waste of resources and pollutes the environment
