Abstract

The invention relates to the technical field of lubricating agents, in particular to calendaring copper foil rolled oil and a preparation method thereof. The calendaring copper foil rolled oil is used for lubricating in the cold-rolled process of calendaring copper foil. The preparation method is characterized by comprising the following steps of: adding N5 engine oil, butyl stearate, dodecanol, nitrogen-containing borate, fatty alcohol polyethylene glycol phosphate, petroleum sodium sulfonate and benzotriazole into a reaction kettle of which the rotation speed is 80 to 120 revolutions / minute sequentially, heating and stirring; and when the temperature is 80 DEG C, keeping the temperature, stirring continuously for 30 minutes, stopping heating, and stirring continuously to room temperature to obtain uniform and transparent oil, namely the required rolled oil. The minimum rolling thickness of the calendaring copper foil lubricated by the rolled oil is 25 micrometers, so that the calendaring copper foil is high in surface smoothness, long in anti-corrosion period and high in annealing detergency.

Description

technical field [0001] The invention relates to the technical field of lubricants, which is used for lubrication in the process of cold rolling of rolled copper foil, in particular to a rolling oil of rolled copper foil and a preparation method thereof. Background technique [0002] With the demand for small, lightweight and high-performance technology development of electronic equipment, the market requires that printed circuit boards must have excellent characteristics and quality. Because of its high strength, toughness and high density, rolled copper foil is widely used in high-frequency high-speed transmission, fine circuits printed circuit board. At the same time, there are higher and updated requirements for copper foil, which are mainly manifested in: low (low roughness), thin (development to 9μm and below), high (high physical properties and reliability), no (no appearance defects) Four aspect. Process lubrication plays an important role in the rolling process of ...
