Abstract

The invention discloses a long-acting water-based metal antirust agent and a preparation method thereof. Dodecyl dicarboxylic acid, carboxymethyl cellulose, inositol hexaphosphate, sodium metasilicate, perfluorocaprylic acid, sodium molybdate, barium titanate, long-chain compound amine boric acid ester, polyethyleneglycol, isopropanol, hydroxyethyl ethylenediamine triacetic acid, 2-ethyl-4-methylimidazole and deionized water are used as raw materials. The preparation method of the long-chain compound amine boric acid ester is improved. All the raw materials are subjected to phased mixed treatment to obtain the water-based metal antirust agent. The long-acting environment-friendly water-based metal antirust agent with the excellent rust-resisting effect is obtained through the preparation method which is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of chemical products and relates to an antirust agent, in particular to a long-acting water-based metal antirust agent and a preparation method thereof. Background technique [0002] 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 astonishing figure; the losses caused by various natural disasters in my country in 2013 were about 580.84 billion yuan, which shows that the losses caused by metal corrosion are far greater than various natural disasters. While causing huge econ...
