Abstract

The invention discloses a water-based rust inhibitor for steel surfaces and a preparation method thereof. The preparation method comprises the following steps: proportionally adding polyisobutylene, triethanolamine, N,N-bis(2-cyanoethyl)formamide, dimethylamino-p-phenol, polyacrylate and deionized water into a stainless steel reaction kettle, heating to 130+ / -5 DEG C, starting stirring, adding surfactant, sebacic acid, glycerol, zinc dihydrogen phosphate, thickener and sorbitol, heating to 185-195 DEG C at the rate of 10-15 DEG C / hour, reacting for 2-3 hours, stopping heating, adding ammonium gluconate, potassium persulfate and borax, and dissolving by evenly mixing. The rust inhibitor has excellent antirust effect for steel, and can form an ultrathin antirust film on the surface to prevent the corrosion from the outside. The water-based rust inhibitor for steel surfaces is nontoxic and harmless to the human body, and has favorable environment-friendly effect; and the antirust time can reach 6-8 months. The method has the advantages of simple technique, wide component sources and low price.

Description

technical field [0001] The invention relates to a steel surface treatment technology, in particular to a water-based antirust agent for the steel surface and a preparation method thereof. Background technique [0002] At present, with the continuous development of industry, the use of steel is also increasing. However, during the production process or the storage process of finished products, steel plates are easily oxidized and rusted when encountering humid air and rainy days, which affects the appearance quality of products. This has brought problems to the use of steel, and the annual loss of steel due to corrosion is very alarming. In order to prevent surface corrosion, antirust treatment must be carried out; Protective oil film, so as to isolate the corrosion of metal by water vapor in the air, and achieve the purpose of rust prevention. However, the use of antirust oil requires a large amount of oil raw materials, which intensifies energy consumption and increases cos...
