[0066] Next, the present invention will be further described through examples. However, the present invention is not limited to the following examples.

[0067] (1) Production of water-based lubricants for plastic processing

[0068] Component (A), component (B), component (C) and component (D) were added to water in the combination and ratio shown in Table 6 (the total amount of component (B) and component (C) was as shown in Table 6 The ratio of the indicated component (A) to the component (D) is adjusted so that the total amount of the components (A) to (D) becomes 1.), and the plastic working water of Examples 01 to 34 and Comparative Examples 01 to 19 were prepared. Department of lubricants. All of these water-based lubricants had a weight ratio of all solids to water of 18.8:85. In addition, the water-based lubricant is used by diluting with water and adjusting the concentration so that the lubricating film after drying becomes the target film amount. In addition, ab...

Abstract

[Problem] The present invention resolves the problems of conventional technology and has as the objective the providing of an aqueous lubricant that is for plastic working of a metal material and having superior gas clogging resistance, post-moisture absorption workability, and high workability at least equivalent to that of conventional applied aqueous lubricants and lubrication processing such as zinc phosphate + soap processing. [Solution] This aqueous lubricant for plastic working of a metal material is characterized by containing, in an aqueous medium: (A) a polymer, and / or a salt thereof, containing a carboxylic acid or a derivative thereof as a constituent monomer; (B) a silicon or phosphorus oxo acid of tungsten or a condensate and / or salt thereof; (C) the hydroxide of an alkali metal; and (D) a lubricating component. The aqueous lubricant for plastic working of a metal material is further characterized in that the solid fraction weight ratio (A) / [(A)+(B)+(C)+(D)] of component (A) and component (B), component (C), and component (D) is 0.05-0.4.

Description

technical field [0001] The present invention relates to a water-based lubricant used in plastic working of metal materials, and more specifically, to a water-based lubricant for plastic working of metal materials excellent in workability after moisture absorption and resistance to slagging and clogging. Background technique [0002] In plastic processing such as forging processing, extrusion processing, and press processing of metal materials, it is necessary to prevent burns, sticking, and heat generation due to metal contact between the metal material and the mold. As substances suitable for this requirement, coatings, oils, soaps and the like having excellent lubricity have been used since ancient times. Among them, zinc phosphate-based chemical conversion coating and soap-based lubricant treatment (hereinafter also referred to as squeeze lubricant (Bonderlube) treatment) which is excellent in processability and has high versatility are often used. [0003] However, ther...
