Novel film forming material for metal surface

Abstract

The invention provides a novel film forming material for a metal surface. The novel film forming material comprises the following components in percentage by weight: 35-46% of hexamethyldisilazane, 8-12% of 2, 2'-azodiisobutyronitrile, 1-3% of p-hydroxybenzoate, 0.01-0.05% of sodium dodecyl benzene sulfonate, 0.01-0.05% of fatty alcohol polyoxyethylene ether sodium sulfate, 0.01-0.05% of cocamidopropyl betaine, 0.01-0.02% of ethylene glycol monomethyl ether, 0.01-0.02% of n-octyltriethoxysilane and the balance of pure water. According to the invention, the novel film forming material is a water-based anti-rust corrosion inhibitor capable of forming a dry film, an anti-rust film layer formed on the metal surface is dry, smooth, fine and free of greasy feeling, and when cleaning is needed in the later period, the anti-rust film layer can be easily cleaned through water washing; and the novel film forming material is beneficial to later cleaning and removal treatment, and can be completely cleaned by using clear water independently, so that the consumption of subsequent complicated process matched chemicals and energy can be reduced, and energy conservation can be realized.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a novel film-forming material for metal surfaces. Background technique [0002] Metal processing parts are prone to rust during production, processing and transportation, which requires the use of anti-rust oil to form a thin film on the metal surface to prevent metal corrosion. It is difficult for machinery not to come into contact with oxygen, moisture or other corrosive media in the air during operation and storage. These substances will undergo electrochemical corrosion and rust on the metal surface. To prevent corrosion, the above substances must be prevented from contacting the metal. Anti-rust agent is a kind of anti-rust products, other types include anti-rust oil, anti-rust paper and so on. Anti-rust agent is a super-efficient synthetic penetrating agent, which can penetrate into rust, corrosion, and oil stains to easily remove rust and corrosion on screws and...
