Problems solved by technology

Ordinary anti-rust liquid contains a large amount of sodium nitrite, which is carcinogenic and is not conducive to environmental protection and human health. However, the use of humectants to prolong the life of anti-rust liquid brings the disadvantages of sticking hands and dust, and cannot prevent rust for a long time
Although the general dura-film anti-rust oil is suitable for long-term anti-rust, and the film is transparent and beautiful, there are few types of colorless and transparent resins, which are unstable and easy to oxidize and change color. They also need organic solvents to dissolve, which brings the danger of flammability and explosion. Not conducive to environmental protection and health
The general anti-rust oil uses mineral oil, which is difficult to degrade, and it will also cause the problem of difficult degreasing when used for short-term anti-rust

Abstract

The invention provides a water-base rust removal antirust agent. The water-base rust removal antirust agent comprises raw materials including, by weight part, 2 to 6 parts of citric acid, 2 to 8 partsof lauryl sodium sulfate, 2 to 4 parts of tartaric acid, 1 to 2 parts of sodium gluconate, 2 to 6 parts of polyaspartic acid, 0.4 to 1.2 parts of oxidized starch, 5 to 10 parts of cetyl-trimethyl ammonium bromide, 10 to 15 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 1 to 2 parts of Turkey red oil, 1 to 3 parts of carboxymethylcellulose, 2 to 8 parts of mesoporous silica, 10 to 20parts of ethylene glycol, 10 to 20 parts of propanediol butyl ether and 70 to 95 parts of water. The invention further provides a preparing method of the water-base rust removal antirust agent. The water-base rust removal antirust agent has multiple functions of rust removal, dirt removal, phosphatization, passivation and the like, a reaction is carried out at the normal temperature, the rust removal time is short, the antirust time is long, and corrosion to the metal is avoided.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a water-based rust remover and antirust agent and a preparation method thereof. Background technique [0002] Rust prevention on metal surfaces is an important subject in industrial production. Traditional antirust liquids and antirust oils have both advantages and disadvantages. Ordinary anti-rust liquid contains a large amount of sodium nitrite, which is carcinogenic and is not conducive to environmental protection and human health. However, the use of humectants to prolong the life of anti-rust liquid brings the disadvantages of sticking hands and dust, and cannot prevent rust for a long time . Although the general dura-film anti-rust oil is suitable for long-term anti-rust, and the film is transparent and beautiful, there are few types of colorless and transparent resins, which are unstable and easy to oxidize and change color. They also need orga...
