Abstract

The invention provides a universal nonferrous metal and stainless steel cold rolling oil composite additive and a preparation method thereof and belongs to the field of lubricating agents. According to the universal nonferrous metal and stainless steel cold rolling oil composite additive, lauryl alcohol, butyl stearate, pentaerythritol oleate and lauric acid are selected as oily agents; 2,6-di-tert-butyl-4-methylphenol is selected as an antioxidant; benzotriazole and thiadiazole derivatives are used as metal deactivators; dialkyl phosphorodithioate serves as an antiwear agent; and hydrogenated base oil serves as a solvent. The alcohol-ester type oily agents are mainly used for compounding with a little amount of acid oily agents as supplementation; a little amount of dialkyl phosphorodithioate is used as the antiwear agent to reinforce an oil film so as to improve the surface quality of a rolled stock; the service life of rolling oil is prolonged through a little amount of the antioxidant and the metal deactivators, the cyclic use frequency is increased, and rolled pieces are protected against corrosion. The universal nonferrous metal and stainless steel cold rolling oil composite additive is convenient to use, low in cost and little in dosage, and has the characteristics of high oil film strength, good antiwear and antifriction effect, high oxidation resistance and excellent annealing performance.

Description

technical field [0001] The invention relates to the field of lubricants and cold rolling of metal sheets, strips and foils, belongs to the lubrication in the metal processing process, and specifically relates to a general-purpose cold rolling oil composite additive and a preparation method thereof. Background technique [0002] During the cold rolling of non-ferrous metals (such as aluminum plates, strips, foils, copper foils, etc.) . [0003] Rolling oil is composed of base oil and additives. Modern new base oils are mainly hydrotreated mineral oils, and their components are mainly mixtures of paraffins and naphthenes with different carbon chain lengths; additives can improve the specific properties of oil products, Improves the lubricating properties of mineral oils. Rolling oil often needs to add a certain amount of oily agent, anti-wear agent, antioxidant, etc. to achieve the effect of improving lubrication. A single type of additive cannot exert a comprehensive effec...
