Problems solved by technology
In this way, in the development of the antirust oil composition, even if various components are added according to the desired performance, the desired performance expected by the various components may not be obtained. Therefore, it is extremely difficult to combine additives for the desired performance.

The present invention provides: a rust preventive oil composition which has excellent rust preventive properties and easy degreasability, while exhibiting excellent stability at low temperatures and excellent adhesion preventing properties; and a method for producing a rust preventive oil composition. The rust preventive oil composition and the method for producing a rust preventive oil composition are disclosed. The rust preventive oil composition contains (A) a solvent that has a kinematic viscosity at 40 DEG C of from 0.1 mm<2> / s to 10.0 mm<2> / s (inclusive), (B) a base oil that has a kinematic viscosity at 40 DEG C of from 100.0 mm<2> / s to 200.0 mm<2> / s (inclusive), (C) a metal sulfonate that has a base number of 50 mgKOH / g or less, (D) an overbased metal sulfonate that has a base number of 300 mgKOH / g or more, (E) a wax that has an acid value of 10 mgKOH / g or more, (F) a full ester of a polyhydric alcohol and (G) a partial ester of a polyhydric alcohol, and which is configured such that the contents of the component (D), the component (E), the component (F) and the component (G) relative to the total content of the components (A)-(G) are 2.6% by mass or more, 1.5% by mass or more, 2.6% by mass or more, and from 0.5% by mass to 4.5% by mass (inclusive), respectively.
Description
technical field [0001] The present invention relates to an antirust oil composition and a manufacturing method thereof. Background technique [0002] For metal materials made of metals such as iron, anti-rust oil is generally applied to the metal surface in order to prevent rust and spots on the metal surface during the manufacturing process or before and after the product is launched. Therefore, rust preventive properties for preventing rust are first required for the rust preventive oil composition. [0003] As such an antirust oil composition, for example, a base oil composed of mineral oil and / or synthetic oil, a sulfonate, and a partial ester selected from polyhydric alcohols, oxidized wax salts, esterified oxidized waxes, lanolin Antirust oil composition of fatty acid salt, esterified lanolin fatty acid, and at least one compound of fatty acid salt (for example, refer to Patent Document 1); containing low-viscosity mineral oil, high-viscosity mineral oil, fatty acid a...
