Abstract

The invention relates to a metal antirust agent meeting the spraying adhesion and a preparation method of the metal antirust agent. The metal antirust agent comprises the following components and is prepared from the following raw materials in parts by weight: 18-30 parts of a polyquaternium-hyperbranched benzimidazole block polymer, 10-16 parts of polyacrylate, 5-8 parts of a surfactant, 0.5-2 parts of an organic phosphonic acid compound, 4-8 parts of ferrocene, 5-9 parts of a defoamer, 3-8 parts of hydroxypropyl methyl cellulose, 0.2-1.2 parts of a pH regulator, and 70-90 parts of deionizedwater; and the preparation method comprises the following steps in the preparation: adding the polyquaternium-hyperbranched benzimidazole block polymer, the polyacrylate and the deionized water into areaction kettle, raising the temperature to 105-20 DEG C, stirring, adding the organic phosphonic acid compound and the surfactant; then raising the temperature to 150-160 DEG C, then adding the hydroxypropyl methyl cellulose, the ferrocene and the defoamer, adding the pH regulator, and regulating the pH to 6-8. Compared with the prior art, the metal antirust agent is high in stability, a film layer is electrically conductive, the postprocessing of a metal part is convenient, the anti-rust property and the anti-corrosion property are excellent, and the spraying adhesion is excellent.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and relates to a metal antirust agent satisfying spray adhesion and a preparation method thereof. Background technique [0002] With the continuous development of modern industry, the use of steel is also increasing. In the process of production, storage and transportation, if the steel is not treated with antirust, it will rust in a short period of time, which will affect the appearance and performance of the finished steel. It will have adverse effects, and serious corrosion will even cause the steel to be scrapped. The rusting of iron and steel causes huge losses to the national economy. Every year, tens of millions of tons of steel are scrapped due to rusting all over the world. In 2000, the economic loss caused by corrosion in my country reached 500 billion yuan. This poses a problem for the use of steel, which must be treated in order to prevent the surface from rusting. T...
