Problems solved by technology

For traditional water-based antirust agents, although they do not contain or contain less oily substances, their systems often contain harmful substances such as sodium nitrite and nitrosamines that are likely to cause cancer, causing serious damage to the life and health of operators. threaten
[0005] It is used to form a metal chemical conversion film on the surface of steel products to inhibit the corrosion of the metal surface. Although it has achieved a certain anti-rust effect, the phosphate plasma contained in the waste liquid after treatment does not meet the requirements of environmental protection. Under certain conditions, amino acids and other amines in protein in the body, gastric acid and gastric juice are converted into strong carcinogenic nitrosamines, which seriously threaten the health of operators

Abstract

The invention relates to a water-based antirust agent and its preparation method and application. Including raw materials in the following weight ratio: 1-40% rust inhibitor, 1-10% corrosion inhibitor, 2-10% dispersant, 0.2-5% buffer, and the balance is deionized water; the rust inhibitor includes carboxylic acid And its derivatives, borates, silicates, alcohol amines and their derivatives, nano-zinc oxide aqueous dispersion, polymer substances, phytic acid solution. It has the effect of environmental protection, and forms a film layer on the surface of cold-rolled steel. The anti-rust effect of the film layer is good, and there is no obvious rust after being placed at room temperature for one month. After salt spray treatment, the surface of the cold-rolled steel substrate will not produce a lot of corrosion, which can meet the needs of enterprises.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a water-based antirust agent and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Metal workpieces need to go through degreasing, washing, film forming, coating and other processes before use. Due to the temperature and humidity of the operating environment, if the workpiece is not treated in time, it will cause corrosion of the workpiece, destroy the original color, shape and mechanical properties of the metal workpiece, affect the service life of the workpiece, and cause serious economic losses and Direct wa...
