Problems solved by technology

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

Abstract

The invention discloses a water-based copper antirust liquid which is prepared from the following raw materials in parts by weight: 2-3 parts of mercaptobenzothiazole, 3-4 parts of polyoxyethylene alkyl ether, 1-2 parts of sodium di-sec-octylmal-eacesulfonate, 1-2 parts of fatty alcohol polyoxyethylene ether acrylate, 1-2 parts of sodium dodecyl sulfonate, 2-3 parts of sodium carbonate, 0.5-1.1 parts of 2-methyl imidazoline, 10-15 parts of itaconic acid, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. The antirust liquid has good cleaning effect, and has good combination property with a copper surface; with combined use of the high-molecular resin monomers and the chelating agent, the antirust liquid allows an antirust layer to be continuous and dense, has quite good antirust effect, can be sprayed directly without tedious deoiling and decontamination processes, can keep the copper surface non-corrosive and non-discoloring for a long term, is suitable for long and short term rust prevention of copper, and has the advantages of environmental protection, energy saving and low cost.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to a water-based copper antirust solution 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, which bri...
