Palmitoleic amide type water-based gas-phase antirust concentrate and preparation and use methods thereof

Abstract

The invention discloses palmitoleic amide type water-based gas-phase antirust concentrate. The palmitoleic amide type water-based gas-phase antirust concentrate is prepared from the following raw material of: an palmitoleic amide compound antirust agent, a gas-phase corrosion inhibitor, an amino acid-based triazine antirust agent, nitrobenzoate alcohol amine salt, hexamethylenetetramine, monoethanolamine benzoate, a special water-based antirust agent, a metal complexing agent, a defoaming agent and a film-forming agent. According to the palmitoleic amide type water-based gas-phase antirust concentrate, water is used as a carrier, and the green and environment-friendly palmitoleic amide compound antirust agent is a main antirust agent, the antirust concentrate is free of nitrite and other toxic and harmful components to the human body and the environment, and has excellent performance in contact rust prevention, gas phase rust prevention, lubrication, infiltration and chemical adsorption, the antirust concentrate can prevent rust for high precision metal products without damaging the surfaces of the high-precision metal products, and the antirust concentrate facilitates water cleaning, energy-saving and environment-friendly, and can meet the requirements of short-term rust prevention between processes and long-term rust prevention of packaging and sealing of common steel and various non-ferrous metal devices and products .

Description

Technical field: [0001] The invention relates to a palm oleic acid amide-type water-based gas-phase antirust concentrate and its antirust application field, in particular to a palm oleic acid amide water-based gas-phase antirust concentrate and a preparation and use method thereof. Background technique: [0002] Metals are widely used in all aspects of industrial production and human life, and play a pivotal role in technological development and economic construction. However, metal products are prone to rust in the process of processing, production, transportation and storage, which will cause losses to metal products in terms of color, luster, and shape. In severe cases, it will lead to performance damage, resulting in serious accidents and economic losses. Although the traditional anti-rust oil has a good sealing effect, it not only has poor appearance, cumbersome process, time-consuming and troublesome effect after application, but also needs to be cleaned before unseali...

Problems solved by technology

[0003] Although there are many reports on water-based anti-rust fluids, these products either contain sodium nitrite and chromate, which are harmful to the human body and the environment; or contain organic resins, which are cross-linked by resins to form polymers on the surface of steel substrates. film; or containing base oil, using the emulsification of surfactants to form an oil film on the surface of the steel substrate; or containing inorganic salts (such as alum, silicate, borate, carbonate, sulfate, phosphate, chloride salt ), these inorganic salts are easy to form a chemical oxide film with the steel substrate, and at the same time, the inorganic salts are also easy to precipitate solid grains or white spots on the surface of the steel substrate, and do not have gas phase antirust performance, which can easily cause metal products, especially precision metal products.
