Abstract

The invention provides a vitrification agent and a preparation method and an application method thereof. The vitrification agent contains the following raw materials of, by weight, 1%-5% of ammonium fluorozirconate, 0.2-1.5% of acetic acid, 0.5-0.8% of citric acid, 0.5-3% of vinyl silane, 0.1-3% of sodium chloride, 0.2-1% of zinc oxide and the balance water. The preparation method of the vitrification agent mainly comprises the following steps of 1, under normal temperature and normal pressure, water which accounts for two thirds of a formula amount is added into a reaction container, and thewater is slowly and non-stopping stirred; 2, the ammonium fluorozirconate, the acetic acid, the citric acid, the vinyl silane, the sodium chloride and the zinc oxide are sequentially and slowly addedinto the reaction container according to the formula amount while the stirring is kept; and 3, after a liquid stirring tool is continuously stirred for a certain time, the residual water is added andthe density is adjusted until 1.01-1.03 g / ml. The application method of the vitrification agent mainly comprises the following steps of degreasing treatment, two water washing, surface treatment on the vitrification agent prepared by the method, washing with pure water, drying, spraying and solidifying.

Description

technical field

[0001] The invention relates to the technical field of metal surface treatment, in particular to a ceramic agent and its preparation method and use method. Background technique

[0002] Steel usually needs to be pre-treated before painting. The chemical pre-treatment method is usually to form a chemical conversion film on the surface of the steel. The conversion film must have a certain anti-corrosion ability to ensure that the parts do not return to rust before spraying. It can also increase the roughness of the surface of the part and enhance the bonding force between the coating and the substrate.

[0003] At present, most of the pretreatment of iron and steel adopts phosphating treatment process. Although the phosphating process can meet the production requirements of pretreatment, phosphating will produce a large amount of phosphating slag, and the carcinogenic sodium nitrite will be used as a carcinogen during the production process. Phosphating accele...
