Water-soluble lubricant for metal material processing

Abstract

The invention discloses a water-soluble lubricant for metal material processing. The lubricant is prepared from the following raw materials in parts by weight: 50-55 parts of modified vegetable oleicacid, 20-25 parts of glycerinum, 5-8 parts of sodium sulfamate, 30-35 parts of absolute ethyl alcohol, 5-8 parts of an antirust auxiliary agent, 3-5 parts of a mildew-proof sterilization auxiliary agent, 3-5 parts of glyceryl monolaurate and 60-65 parts of deionized water. The invention further discloses a preparation method of the water-soluble lubricant for metal material processing. In the preparation process of the water-soluble lubricant for metal material processing provided by the invention, the modified vegetable oleic acid, the antirust auxiliary agent, the mildew-proof sterilizationauxiliary agent, the glyceryl monolaurate and the sodium sulfamate are added, so that the extreme pressure property, antirust property, oxidation stability, water solubility, mildew-proof bactericidalproperties and hygroscopicity of the lubricant are greatly improved, the processability of a metal material is improved, the service life of a tool is prolonged, the antirust, mildew-proof and bactericidal properties of a processed object are improved, and the lubricant has good market application prospects.

Description

technical field [0001] The invention belongs to the technical field of lubricants, in particular to a water-soluble lubricant used for metal material processing. Background technique [0002] With the advancement of industry, metal processing has become an indispensable part of modern technology. In order to improve metal performance in metal processing, various additives are often added. Metal processing lubricants are also the most common metal processing additives. Metal processing The use of lubricants can improve the finish of the metal surface, improve the processing performance, prolong the life of the tool, improve the anti-rust performance of the processed object, and improve the durability of the tool. [0003] At present, the metal processing lubricants on the market mainly have four main functions: lubrication, rust prevention, cleaning and cooling. , the cooling effect is average, the extreme pressure is poor, the lubricating film bears the load in the metal pr...

Problems solved by technology

[0003] At present, the metal processing lubricants on the market mainly have four main functions: lubrication, rust prevention, cleaning and cooling. , the cooling effect is average, the extreme pressure is poor, the lubricating film bears the load in the metal processing process and is easily squeezed out of the friction surface, which increases the amount of lubricant used, the oxidation stability is poor, and the properties of oxygen in the air are easily changed, resulting in lubricating effect Deterioration, at the same time, it is difficult to clean the lubricant, and the use effect is poor

[0004] Chinese invention patent CN101418248A discloses a lubricant for metal material processing, its raw materials include by weight: 100 parts of vegetable oil, 1-2 parts of Span, 0.2-0.7 parts of urea, 5-7 parts of industrial alcohol, emulsifier 6-9 parts; the lubricant prepared by the invention has a good lubricating effect, but the lubricant prepared by the invention has poor rust resistance, mildew resistance and bactericidal properties, poor oxidation stability, poor extreme pressure performance, general cooling effect, is not easy to clean, and is not conducive to metal The use of processing, the market prospect is small
