A kind of environment-friendly water-based gas-phase long-term antirust liquid composition and its preparation and use method

Abstract

The invention discloses an environment-friendly water-based gas-phase long-acting antirust liquid composition, which is composed of oleic acid derivative antirust, triazine antirust agent, organic carboxylic Amines, benzotriazole corrosion inhibitors, monoethanolamine benzoate, metal complexing agents, defoamers, water and pH regulators. The environment-friendly water-based gas-phase long-acting antirust liquid composition of the present invention uses water as a carrier, contains oleic acid derivative antirust agent composition, does not contain nitrite and other toxic and harmful components to the human body and the environment, is safe and environmentally friendly, and has excellent contact Anti-rust ability, gas-phase anti-rust ability, lubricating ability, wetting ability and chemical adsorption ability, that is, it does not affect the surface quality and precision of steel balls (especially >G10 level), and it is easy to clean and water treatment, saving costs, and meets carbon steel, Long-term anti-rust and short-term anti-rust requirements between processes for storage and packaging of steel balls made of stainless steel and other steel-based materials.

Description

technical field [0001] The invention relates to an antirust liquid composition, in particular to an environment-friendly water-based gas-phase long-acting antirust liquid composition for steel balls and a preparation and use method. Background technique [0002] Usually, the finished steel balls are packaged with oil or vacuum for anti-rust packaging, and then placed in packaging bags or packaging barrels for packaging, transportation and long-term storage. Oil-coated anti-rust packaging is not only costly, but also not conducive to environmental protection. Under the trend of increasingly stringent environmental protection, without affecting the long-term anti-rust requirements of steel ball surface quality and precision (especially >G10 level), "replacing oil with water" adopts water-based environmental protection gas-phase anti-rust liquid for steel ball anti-rust packaging The application value and social significance are great.

Problems solved by technology

[0004] Although there are many published patents, these patents either contain sodium nitrite, which is harmful to the human body and the environment; or contain organic resins, which use resins to cross-link to form polymer films on the surface of steel substrates; or contain base oils, which use surfactants The emulsification effect forms an oil film on the surface of the steel substrate; or contains inorganic salts (such as alum, silicate, borate, carbonate, sulfate, phosphate, chloride), these inorganic salts are easy to chemically react with the steel substrate At the same time, inorganic salts are easy to precipitate solid grains or white spots on the surface of steel substrates, and do not have gas phase antirust performance, which can easily cause discoloration and surface gloss of steel balls, affecting surface quality and accuracy

Therefore, the disclosed patents are not suitable for long-term antirust protection of steel balls (especially >G10 grade steel balls)
