Rust-preventive oil composition

Abstract

Disclosed is a rust-preventive oil composition with a kinetic viscosity of 20 to 100mm2 / s at 40 DEG C that contains: (A) as a base oil, at least one type of oil chosen from among mineral oils and synthetic oils; (B) 0.1 to 10% by mass of water based on the total amount of the composition; and (C) one or more particular rust-preventive additives chosen from a group comprising sarcosine compounds, nonionic surfactants, sulfonate, ester, amine, carboxylic acid, fatty acid amine salts, carboxylate, paraffin wax, oxidized wax salt, and boron compounds. The rust-preventive oil composition is effective in preventing rust development over the long term on metallic components such as steel sheets, bearings, steel balls, and guide rails, even when rust-causing factors that adhere onto such objects, such as when these components are assembled with bare hands, remain.

Description

technical field [0001] The present invention relates to an antirust oil composition. Background technique [0002] At present, in the field of metal components such as steel plates, bearings, steel balls, and guide rails, when the components are installed with bare hands, factors that cause rust such as chlorides are attached. Therefore, it is necessary to take countermeasures such as washing and removing rust-generating factors or applying anti-rust oil. Such anti-rust oils are generally compounded with anti-rust additives (corrosion inhibitors) such as sulfonic acid metal salts, sulfonic acid amine salts, carboxylic acids, esters, amines, etc., but when the object to be treated is stored for a long time, only anti-rust additives ( Corrosion inhibitors), often do not obtain sufficient rust resistance. Therefore, it has been proposed to use an antirust oil blended with heavy components such as wax and petroleum grease in addition to the above-mentioned antirust additives t...

Problems solved by technology

[0004] In addition, it is also proposed that in the existing metal processing process, the two steps of the cleaning process and the anti-rust process are unified, and a cleaning and anti-rust agent composition having both detergency and anti-rust properties (for example, refer to Patent Document 3 ), but it cannot be said that the rust resistance for long-term use is still sufficient

[0005] As mentioned above, in the prior art, when rust-generating factors are attached to various metal parts or metal parts assembled by hand, there is no anti-rust oil with excellent anti-rust performance for long-term use, so it is desired to develop Anti-rust oil that maintains anti-rust properties over a long period of time
