[0028] Heat the refined mineral oil to 40°C, add the required amount of oily agent, extreme pressure agent, copper corrosion inhibitor and antioxidant in sequence during stirring, stop stirring and heating after stirring for 1 hour, and filter and fill after standing for 2 hours loading. The type and amount of each component in the composition are specifically shown in Table 1. The performance test results are shown in Table 2.

[0029] Wherein, the base oil is a refined narrow fraction dearomatized solvent oil with a distillation range of 277-307°C and a viscosity of 4.35 mm 2 / s, the flash point (opening) is 145°C.

Abstract

The invention relates to an oil composition for copper foil rolling and uses thereof, mainly overcoming the problems of the prior art, namely poor lubrication performance, much oil mist and poor low-temperature annealing detergency. The oil composition adopts a mixture comprising following components by weight: a) 90-98 parts of base oil; b) 1-10 parts of an oiliness agent; c) 0.5-4 parts of an extreme pressure agent; d) 0.05-1 part of a copper corrosion inhibitor; and e) 0.05-1 part of an antioxidant, wherein the base oil is selected from purified narrow-fraction dearomatization solvent oil; the oiliness agent is selected from C12-C14 fatty acid methyl ester and C10-C14 alcohol; the extreme pressure agent is selected from tributylphosphite; the copper corrosion inhibitor is selected from benzotriazole and derivatives thereof; and the antioxidant is at least one of N-phenyl-alpha-naphthylamine or dialkyldiphenylamine. By adoption of the abovementioned technical scheme, the problems are solved well, and the oil composition can be used for process lubrication in a copper foil cold-rolling process.

Description

[0001] Technical field [0002] The invention involves a copper foil rolling oil composition and its use. Background technique [0003] Copper foil is widely used in the production of special cables, printing circuit boards, wires and transformers. With the rapid development of electronic products and the rapid development of traffic communication.Electronic devices are becoming increasingly miniaturized, the continuous development of the surface installation technology of printing circuit, and the growing growth of multi -layer printing circuit board production, which prompts the printing circuit to tend to be fine, high -reliability, high stability, and high functional development.The performance and variety of copper foil put forward higher renewal requirements, making copper foil production technology a new development trend, and the market's requirements for its performance and accuracy are also increasing.High -intensity, high ductility, getting thinner, etc., which put for...
