Abstract

The invention discloses an environment-friendly steel surface anti-rust agent and a preparation method thereof. The preparation method comprises the following steps: mixing polyethylene wax, liquefied paraffin, methyl-2-imidazoline and deionized water according to weight parts, stirring and heating to 120-130 DEG C, insulating for 1 hour, and cooling to 40-50 DEG C; adding 3-aminopropyltrimethoxysilane, epoxy rice bran oil, amino trimethylene phosphonic acid, isopropanolamine, sodium gluconate, benzotriazole, a surfactant, carboxymethyl cellulose, a thickening agent and sodium lauryl sulfate, and stirring until the components are completely dissolved. The anti-rust agent uses water as a dispersing medium, has excellent environment-friendly performance, is non-combustible and unexplosive, does not have pollution, and does not have toxicity and risk on human bodies. The anti-rust agent has an excellent construction performance, cannot corrode metal in the using process, is simple and convenient to apply, and can be used for effectively protecting metal from corrosion by soaking, spraying, coating and other modes. The anti-rust period of the anti-rust agent can be 10-12 months in a normal environment.

Description

technical field [0001] The invention relates to a steel surface treatment technology, in particular to an environment-friendly steel surface 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 c...
