Water-soluble anti-rust fluid between processes and preparation method thereof

Abstract

The present invention discloses a water-soluble anti-rust fluid between processes, which comprises the components in parts by weight of 5-8 parts of sodium molybdate, 2-4 parts of zinc gluconate, 1-2 parts of sodium benzoate, 2-4 parts of glycerinum, 0.1-0.2 parts of sodium carboxymethyl cellulose, 80-90 parts of deionized water. The water-soluble anti-rust fluid provided by the present invention contains neither materials with larger toxicity such as sodium nitrite, dichromate, or volatile organic amine, etc. nor components with eutrophication property such as phosphate or nitrate, possessing less toxic, with environmental protection to a certain extent; if the anti-rust fluid provided by the present invention is used for rust prevention to iron and steel parts, no iron mold is to produce within 20-40 days, which is capable of meeting the requirements of rust prevention between processes for ordinary steel workpiece machining and the requirements of rust prevention for short-term storage, and the fluid can be easily removed with washed method, with the advantages of low cost of production and convenient preparation.

Description

technical field [0001] The invention mainly relates to an antirust liquid, in particular to a water-soluble antirust liquid between processes. Background technique [0002] Iron and steel products generally need to be processed through multiple processes. The semi-finished products will be rusted due to the influence of processing media, humid air and hand sweat during transportation and storage between processes. Therefore, temporary inter-process protection is often required. Rust, in which the use of anti-rust liquid coating the surface of the workpiece is a common method. The anti-rust liquid includes water-based anti-rust liquid with water as the dispersion medium and oil-based anti-rust liquid with mineral oil as the dispersion medium (that is, anti-rust oil). Oil-based anti-rust liquid is mainly composed of mineral oil and oil-soluble corrosion inhibitor. When it is applied on the surface of steel parts, it is difficult to clean and remove; if it is not cleaned, ...

Problems solved by technology

However, the traditional water-soluble antirust liquid is prepared with water-soluble corrosion inhibitors such as sodium nitrite, dichromate or volatile organic amines. These highly toxic substances are likely to cause serious harm to the human body and the environment.
