Abstract

PURPOSE:To prevent the corrosion of a press die and prolong the life of the die by incorporating benzotriazole into a water-soluble lubricant composed mainly of a base oil. CONSTITUTION:At least 0.2wt.% benzotriazole is incorporated into a water-soluble lubricant made by adding, at need, a corrosion inhibitor, an antiseptic, etc., to a base oil consisting of an oil or fat and a wax.

However, when a cemented carbide die made of a cemented carbide containing Co is used as the stamping die, if a conventional water-soluble lubricant is used for the stamping, the cemented carbide is hardened. There is a problem that a large amount of Co is eluted in the mold, which may corrode the press mold and shorten the mold life.

The water-soluble lubricant is mainly composed of a base oil composed of oils and fats such as synthetic oil and waxes, and further prepared by adding a chlorine-based extreme pressure additive, an anticorrosive, an antiseptic, etc., if necessary. There is something to be done. Here, when the base oil is water-soluble, the water-soluble lubricant can usually be used as it is by dissolving it in water and diluting it to a concentration of several%, but when the base oil is water-insoluble, a surfactant is used. Is prepared to be water-soluble. In the present invention, "water-soluble" of a water-soluble lubricant is a concept including not only a state of being dissolved in water but also a state of being stably dispersed in water as a stable suspension.

The water-soluble lubricant is used by blending it in an amount of 0.2% by weight or more. If the blending amount is less than 0.2% by weight, the effect of suppressing Co elution due to the blending of benzotriazole cannot be sufficiently obtained. As described above, the benzotriazole may be mixed with the water-soluble lubricant, diluted with water, and then pressed or pressed while being applied by spraying it onto a press die or a work material. In performing press work in this way,
