Embodiment 1

[0195] 16.8 g of potassium tetraborate was added, stirring 77.4 g of deionized water with a propeller, and it heated to 60 degreeC, and dissolved it. Afterwards, 0.2 g of a nonionic surfactant (manufactured by Shin-Etsu Chemical Co., Ltd.) and 1.6 g of synthetic mica (organic A) that had been prepared were added while stirring with a propeller at room temperature, and the mixture was mixed with a homogenizer. The liquid was stirred for 1 hour to disperse in the liquid. Thereafter, 4 g of a polyethylene wax emulsion (manufactured by Mitsui Chemicals Co., Ltd.) was added with propeller stirring to obtain 100 g of a treatment liquid having a concentration of about 20%.

Embodiment 2

[0197] While propeller stirring 58.1 g of deionized water, 24.2 g of an epoxy resin aqueous solution (manufactured by Arakawa Chemical Industry Co., Ltd.), 0.4 g of a nonionic surfactant (manufactured by Shin-Etsu Chemical Co., Ltd.), 3 g of synthetic smectite (organic C) and 6 g of calcium carbonate were prepared, and the liquid was stirred for 1 hour using a homogenizer to disperse in the liquid. Thereafter, 8.3 g of a zinc stearate emulsion (manufactured by Chukyo Oil & Fat Co., Ltd.) was added with propeller stirring to obtain 100 g of a treatment liquid having a concentration of about 20%.

Embodiment 3

[0199] 13 g of sodium citrate was added, stirring 76.2 g of deionized water with a propeller, and it heated at 60 degreeC, and was made to melt|dissolve. After that, 0.2 g of nonionic surfactant (manufactured by Shin-Etsu Chemical Co., Ltd.), 3 g of synthetic smectite (organic C) and 2 g of zinc phosphate were added while stirring with a propeller at room temperature. The liquid was stirred for 1 hour with an evaporator to disperse in the liquid. Thereafter, 5.6 g of a zinc stearate emulsion (manufactured by Chukyo Oil & Fat Co., Ltd.) was added with propeller stirring to obtain 100 g of a treatment liquid having a concentration of about 20%.

Abstract

To provide a lubricant for plastic processing of metal materials which is also applicable in severe plastic deformation applications, does not have a black appearance that significantly stains a working environment, and does not tend to generate lubrication residue that cause molding defects. A lubricant for plastic processing of metal materials characterized by comprising in the range of 5-95%, in solid content ratio, an organic modified clay mineral supporting a cationic organic compound between the layers of the layered clay mineral.

Description

technical field [0001] The present invention relates to a lubricant for reducing burn and frictional resistance at the friction interface between a metal material to be processed and a tool such as a mold. Alloys, copper and copper alloys, magnesium and magnesium alloys, etc., which become metal materials to be processed are produced when plastic processing such as forging, wire drawing, pipe drawing, calendering, and rolling is performed. [0002] The technical field in which the present invention can function is the entire field of cold plastic working of the metal material, and the most suitable technical field is the field of cold forging, which is prone to high contact pressure at friction interfaces. [0003] More specifically, the present invention relates to a non-black lubricant for plastic working of a metal material that exists at the friction interface between a metal material to be processed and a tool such as a mold, and exhibits both properties of burn resistanc...
