Hardware salt-spray-resistant antirust liquid and preparation method thereof

Abstract

The invention discloses a hardware salt-spray-resistant antirust liquid which is prepared from the following raw materials in parts by weight: 2-3 parts of polyoxyethylenated castor oil, 1-2 parts of sodium benzoate, 12-14 parts of diethylene glycol monobutyl ether, 8-10 parts of 6-hexanediol diacrylate, 2-4 parts of propyl gallate, 3-5 parts of citric acid, 1-2 parts of rosin amine, 6-8 parts of melamine, 6-8 parts of butyl methacrylate, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. The hardware antirust liquid has strong salt spray resistance ability, can form a layer of dense protective film on the surface of copper, iron, stainless steel or other metals, effectively prevents outside matters from corroding the metals, does not affect conductive welding, and allows the protective film to be easy to clean up. The antirust liquid allows a workpiece and a workpiece to be not stuck together, has strong anti-fingerprint, anti-discoloration and anti-oxidation abilities, can be operated with the original liquid under the normal temperature, and saves energy. The antirust liquid is applicable to surface rust prevention of copper, iron, stainless steel and other metals and electroplating metals.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to a salt spray antirust solution for hardware 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 water 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 water 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, whic...

Ordinary anti-rust water 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 water 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. It is 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
