Abstract

The invention discloses a micro emulsion type metal anti-rusting liquid and a preparation method thereof. The micro emulsion type metal anti-rusting liquid comprises base oil, an anti-rusting agent, a surfactant, silica sodium, thiourea, sodium metabisulfite, nitrogenous trimethylene phosphoric acid, benzotriazole, myo-inositol hexakis dihydrogen phosphate, vinyl acetate, trimethyl ammonium chloride, methacrylic acid dimethylamino ethyl ester, agar and deionized water. The preparation method comprises the following steps: firstly, mixing the base oil, the anti-rusting agent, silica sodium and thiourea, stirring, heating, subsequently adding myo-inositol hexakis dihydrogen phosphate, stirring so as to obtain a mixture I, further adding the surfactant, sodium metabisulfite, nitrogenous trimethylene phosphoric acid and benzotriazole into the deionized water, heating, adding vinyl acetate, and stirring so as to obtain a mixture II, mixing the mixture I and the mixture II, further adding the rest components, heating, and uniformly stirring, thereby obtaining the anti-rusting liquid. By adopting the anti-rusting liquid disclosed by the invention, the anti-rusting time is prolonged, and the anti-rusting effect is improved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a microemulsion metal antirust liquid and a preparation method thereof. Background technique [0002] Metal corrosion is a problem often encountered in production. Metal rust not only damages the shape, color and mechanical properties of the metal workpiece itself, but also reduces the quality of the product, and even makes the product scrapped if it is particularly serious. In 2011 my country's GDP is 7.43 trillion US dollars, and the economic loss caused by corrosion is as high as 220 to 370 billion US dollars, accounting for about 3% to 5% of the national GDP. In order to slow down the corrosion of steel and minimize the loss caused by corrosion, people have taken many anti-corrosion measures, among which the use of anti-rust liquid is the most widely used and most effective one. [0003] Antirust Fluid is a super efficient synthetic penetrant that ...
