Cold rolling emulsified oil for copper and copper alloy and method for manufacturing same

Abstract

The invention belongs to the lubricant field, in particular relating to copper and copper alloy cold rolling emulsifying oil with good stability and a manufacturing method thereof. The compositions by weight percentage are as follows: 60 to 70 percent of neutral machine oil, 4 to 6 percent of palm oil, 3 to 6 percent of sulfurized castor oil, 6 to 9 percent of Arlacel-80, 4 to 7 percent of Tween-60, 1 to 3 percent of oleic acid, 1 to 2 percent of trolamine, 3 to 6 percent of sodium alkane sulfoate with 35 to 45 percent of active matter, 1 to 3 percent of tricresyl phosphate, and 0.01 to 0.1 percent of benzotriazole. The emulsifying oil is produced through the method of stepping, adding and stirring, and heating. When the emulsifying oil is diluted into emulsified liquid with a volume concentration between 1 and 8 percent by water, the emulsified liquid can be directly used for machining processes such as cold rolling of sheet materials and belt materials and the drawing of rod materials of copper and copper alloy and so on. The emulsifying oil has high product surface finish, long anti-corrosion period, good cleanliness of annealing surfaces, no toxicity, no pungent smell, convenient operation, and low cost.

Description

technical field [0001] The invention belongs to the field of lubricants, and in particular relates to a copper and copper alloy cold-rolling emulsified oil with excellent stability and a manufacturing method thereof, which are used for cold-rolling lubrication of copper and copper alloy plates and strips. Background technique [0002] In the copper and copper alloy cold rolling industry, with the continuous improvement of the rolling speed and the surface quality of the rolled piece, the requirements for the rolling mill and rolling lubricant are getting higher and higher. The currently used cold rolling emulsion generally has the disadvantages of poor stability, insufficient lubricating performance, the surface of the rolled piece is easily corroded by the emulsion, and the surface quality after bright annealing is poor. , cold-rolled emulsified oil for copper and copper alloy plates and strips with excellent thermal volatility is a demand development direction of the marke...
