Abstract

The invention discloses a preparation method of a long-acting water-based rust inhibitor. The long-acting water-based rust inhibitor is prepared from the following raw materials: lauryl dicarboxylic acid, carboxymethyl cellulose, inositol hexaphosphate, sodium metasilicate, perfluorooctanoic acid, sodium molybdate, barium titanate, long-chain complex amine borate, polyethylene glycol, isopropyl alcohol, hydroxyethyl ethylenediamine triacetic acid, 2-ethyl 4-methylimidazole and deionized water. The preparation of the long-chain complex amine borate is improved, and the water-based metal rust inhibitor is obtained by mixing the raw materials in stages. and the long-lasting and green and environment-friendly water-based rust inhibitor with a good rust-proof effect is obtained through a simpleand easy-to-manufacture preparation method.

Description

[0001] This application is a divisional application, the original patent number is: 201610290388.2, the application date is April 27, 2016, and the title of the invention is: a preparation method of a long-acting water-based metal rust inhibitor. technical field [0002] The invention belongs to the technical field of chemical products and relates to an antirust agent, in particular to a preparation method of a long-acting water-based metal antirust agent. Background technique [0003] Metal is an indispensable material in modern industry and life because of its excellent characteristics, but metal is easily corroded during use, which brings huge social harm and economic loss. According to reports, the economic loss caused by metal corrosion in my country accounts for 4% of GDP (gross domestic product) every year. my country's GDP in 2013 was 56 trillion yuan. Based on this, the economic loss caused by metal corrosion is estimated to be about 2.24 trillion. This is an astonis...
