Technical Field
The invention relates to the technical field of rust removing and preventing liquid, in particular to a neutral environment-friendly rust removing and preventing liquid.
Background
The rust removing treatment is a basic process before the surface coating of steel. The rust removing method can be divided into two major categories, namely a mechanical method and a chemical method, and the rust removing method has the characteristics of the two major categories and is applicable to different occasions. The chemical method has a series of advantages of good effect, high efficiency, simple process operation, low cost and the like, so the chemical method is widely applied to industry.
A common way in chemical rust removal is to clean the steel surface with a rust removing liquid, such as hydrochloric acid. In order to perform rust protection on the steel surface after rust removal, an oxidizing agent such as nitrite is used in the prior art to passivate the steel surface so as to form a rust-proof passivation layer on the steel surface. However, this treatment method can corrode the surface of the carbon steel and is also not environmentally friendly.
Disclosure of Invention
The invention aims to provide a neutral environment-friendly rust removing and preventing liquid which does not contain chloride ions, adopts the novel organic rust removing and preventing chemical raw materials and does not corrode the surface of carbon steel.
In order to solve the technical problems, the invention adopts the following technical scheme:
the invention provides a neutral environment-friendly rust removal and prevention liquid which is characterized by being prepared from the following raw materials in percentage by volume:
8-12% of surfactant organic grease, 1-2% of degreasing agent isomeric alcohol ether, 2-4% of detergent polyoxyethylene ether phosphate, 1-2% of penetrating agent isomeric alcohol ether amide, 1-2% of antirust agent ethylenediamine oleate and the balance of desalted water.
Further, the volume percentage of the organic grease of the surfactant is 10%, the volume percentage of the heterogeneous alcohol ether of the oil remover is 2%, the volume percentage of the polyoxyethylene ether phosphate of the detergent is 3%, the volume percentage of the heterogeneous alcohol ether amide of the penetrating agent is 1%, the volume percentage of the ethylenediamine oleate of the antirust agent is 2%, and the volume percentage of the desalted water is 82%.
