Abstract

The invention provides cleaning type copper-aluminum composite board cold-rolled rolling oil and a preparation method thereof and belongs to the technical field of technological lubrication. A lubricant is prepared from the following components in percentage by weight: 89.5 percent to 90.65 percent of basic oil containing mineral oil D85, D100 and D115, 0.3 percent to 0.8 percent of extreme-pressure agent containing dialkylphosphorodithiloate, fatty alcohol polyethylene glycol ester and acidic dibutyl phosphite, 9.0 percent to 9.6 percent of oily agent containing lauric acid, lauryl alcohol and butyl stearate and 0.05 percent to 0.1 percent of corrosion inhibitor dimercaptothiodiazole. According to the cleaning type copper-aluminum composite board cold-rolled rolling oil, common aluminum rolling oil is adopted, and phosphorus and alcohol ester type extreme-pressure anti-wearing agents are added, so that the strength of an oil film of the rolling oil can be effectively improved; the lauric acid, the lauryl alcohol and the butyl stearate are used as the compound oily agent, so that the stability of a friction reduction capability of the rolling oil is effectively ensured; meanwhile,less dimercaptothiodiazole is added and used as the corrosion inhibitor and is used for preventing the surface of a copper substrate from being oxidized. The prepared rolling oil has extreme-pressureanti-wearing performance, corrosion resistance and surface cleaning performance.

Description

technical field [0001] The invention relates to the technical field of lubricants, which are used for lubrication in the rolling process of copper-aluminum composite strips, in particular to a clean cold rolling oil for copper-aluminum composite strips and a preparation method thereof. Background technique [0002] Copper-aluminum composite strip has the dual characteristics of high electrical conductivity and thermal conductivity of copper and light weight and low price of aluminum. It is a key functional material for strategic emerging industries such as aerospace, electronics, new energy power generation, automotive power batteries, LED lighting, and communications. . At present, there are relatively few lubricating oils produced solely for copper-aluminum composite plate and strip rolling, and the imported oil is expensive. The problem of process lubrication in the rolling process of copper-aluminum composite strip is becoming more and more prominent. During the rollin...
