Metal water-based rust removal antirust solution and preparing method thereof

Abstract

The invention provides a metal water-based rust removal antirust solution. The metal water-based rust removal antirust solution comprises raw materials including, by weight part, 2 to 6 parts of citric acid, 2 to 8 parts of lauryl sodium sulfate, 2 to 4 parts of tartaric acid, 1 to 5 parts of sodium citrate, 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 polyoxyethylene fatty alcohol sodium sulfate, 1 to 2 parts of OP-10, 1 to 3 parts of chitosan, 2 to 8 parts of mesoporous silica, 10 to 20 parts of PEG200, 15 to 20 parts of propanediol butyl ether and 60 to 90 parts of water. The invention further provides a preparing method of the metal water-based rust removal antirust solution. The metal water-based rust removal antirust solution 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 metal water-based derusting and antirusting liquid 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 ne...

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
