Title:
NONGRAPHITIC LUBRICATING OIL
Document Type and Number:
Japanese Patent JP2586871
Kind Code:
B2
Abstract:
PURPOSE: To obtain the subject product excellent in lubricity without polluting a working environment in carrying out working of carbon steel such as hot forging and rolling by dispersing a carbohydrate, its derivative, a film- strengthening agent and a dispersing agent in a specific proportion in a base oil.
CONSTITUTION: The objective product is obtained by dispersing (A) 10-40wt.% carbohydrate and/or its derivative (preferably starch, etc., of rice or wheat), (B) 2-20wt.% film-strengthening agent (preferably zinc molybdate) and (C) 0.1-20wt.% dispersing agent (e.g. sodium.sulfonate) in a base oil (e.g. refined mineral oil having ≥250°C flash point). This product is prepared by uniformly dissolving or dispersing, e.g. the component (C) in the base oil, then mixing and stirring the resultant mixture while slowly adding the components (A) and (B) thereto, providing a slurry composition and subsequently carrying out the uniform dispersing treatment of the prepared composition with a three-roll mill. Furthermore, the product is preferably used by spray lubricating a metallic mold with the product in its state of a stock solution.
