Abstract

The invention discloses a steel rust inhibitor and a preparation method thereof. The preparation method comprises the following steps: weighing phytate, barium petroleum sulfonate, aluminum naphthenate, sodium tripolyphosphate, diethanolamine, surfactant, zinc dialkyl dithiophosphate, sodium molybdate, amino trimethylene phosphonic acid, tolyl triazole, thickener, acetyl triethyl citrate and deionized water according to parts by weight, adding into a middle, and starting the reaction kettle to stir at 65-70 DEG C until the components are completely dissolved. The steel rust inhibitor is free of harmful components to the human body, has the advantages of favorable rust inhibition property, simple treatment technique, accessible raw materials and low production cost, and is convenient to use. Under the condition of satisfying the operating conditions, the viscosity of the rust inhibitor should be reduced to the lowest value. The steel rust inhibitor with low viscosity is easy for coating, can effectively lower the thickness, and achieves the goals of saving and loss reduction.

Description

technical field [0001] The invention relates to a steel surface treatment technology, in particular to a steel antirust agent 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 costs. Therefore, it is only us...
