Abstract

The invention provides a preparing method of a water-based antirust agent. The method comprises the steps that dodecyl phenyl succinic acid, p-phenylenediamine, dinonyl naphthalene sulfonic acid calcium and oxidized petrolatum are added into water, temperature is raised to 40-60 DEG C, the mixture is stirred, zinc N-ethyl-N-phenyldithiocarbamate, dibutyl succinate and hydrogenated styrene-diene copolymer are added, heat is preserved at the temperature of 40-60 DEG C for 2-5 h on the stirring condition, after chilling is carried out, then hydroxy propyl methyl cellulose, polyphydric alcohol, ethylhexyl acrylate and silica sol are added, heat is preserved at the temperature of 60-80 DEG C for 2-5 h, finally, microcrystalline cellulose, soybean lecithin, hydrogenated castor oil and a surface active agent are added, the temperature is raised to 50-70 DEG C, and the mixture is subjected to ultrasonic treatment and chilling to obtain the antirust agent. The antirust agent can form a film fast at normal and low temperature, the process is environment-friendly and relatively simple, the formed film layer can have isolating and corrosion inhibiting protection effects, and the antirust agent has a good antirust effect.

Description

technical field [0001] The invention belongs to the technical field of antirust agents, and in particular relates to a preparation method of a water-based antirust agent. 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 to human beings. According to reports, my country's annual economic losses due to metal corrosion accounted for 4% of GDP (gross domestic product), and 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 yuan; In my country, the losses caused by various natural disasters in 2013 were about 580.84 billion RMB. It can be seen that the losses caused by metal corrosion are far greater than various natural disasters. Corrosion, while causing huge economic losses, may also lead to the failure of some...
