Vitrified agent and preparation method thereof

Abstract

The invention discloses a vitrified agent which is prepared by the following raw materials according to the parts by weight: 20-30 parts of potassium fluorozirconate or sodium fluorozirconate, 5-10 parts of fluoride, 5-10 parts of complexing agent and 40-60 parts of water. The vitrified agent prepared by the technology has good stability, no sediment and no phosphates, can form a vitrification layer on the surface of steel, zinc and aluminum, has strong binding force with various types of coatings, is applicable to the spraying and soaking at room temperature, does not need a heating device and can reach the aim of saving energy and simplifying the production.

Description

Technical field

[0001] The present invention involves a clapse agent used for clay treatment before the metal surface paint, especially a clayide and its preparation method. Background technique

[0002] At present, many steel products processing enterprises, before the metal product processing paint, only make simple oil removal and rust removal treatment on the metal surface, and does not make detailed chemical processing.By use of the year, rust began to occur, which seriously affected the service life of steel.It is difficult to dissolve in water phosphate protective membranes, but the phosphate technology has high temperature, unstable slot fluid, and high costs. It is easy to reduce the anticorrosive performance of the phosphate film. Invention content

[0003] In order to overcome the lack of existing technologies, the present invention provides a pottery agent and their preparation methods with good rust -proof effects and low production costs.

[0027] A kind of method for preparing above-mentioned vitrifying agent, its steps are as follows:

[0028] 1) Weigh potassium fluozirconate: 20 parts, sodium fluoride: 5 parts, tartaric acid: 5 parts, water: 40 parts.

[0029] 2) Add potassium fluozirconate to 27 parts of water and stir for 2 to 3 minutes until dissolved;

[0030] 3) Add sodium fluoride to the solution prepared in step 2 and stir for 2 to 3 minutes until dissolved;

[0031] 4) Add tartaric acid to the solution prepared in step 3 and stir for 2 to 3 minutes until dissolved;

[0032] 5) Add 13 parts of water to the solution prepared in the step and stir for 10-20 minutes.

Embodiment 2

[0034] A kind of method for preparing above-mentioned vitrifying agent, its steps are as follows:

[0035] 1) Weigh 25 parts of sodium fluozirconate, 7 parts of hydrofluoric acid, 7 parts of tartaric acid, and 50 parts of water.

[0036] 2) Add sodium fluozirconate to 34 parts of water and stir for 2 to 3 minutes until dissolved;

[0037] 3) Add hydrofluoric acid to the solution prepared in step 2 and stir for 2 to 3 minutes until dissolved;

[0038] 4) Add tartaric acid to the solution prepared in step 3 and stir for 2 to 3 minutes until dissolved;

[0039] 5) Add 16 parts of water to the solution prepared in step 4 and stir for 10-20 minutes.

Embodiment 3

[0041] A kind of method for preparing above-mentioned vitrifying agent, its steps are as follows:

[0042] 1) Weigh potassium fluozirconate: 30 parts, hydrofluoric acid: 10 parts, tartaric acid: 10 parts, water: 60 parts.

[0043] 2) Add potassium fluozirconate to 40 parts of water and stir for 2 to 3 minutes until dissolved;

[0044] 3) Add hydrofluoric acid to the solution prepared in step 2 and stir for 2 to 3 minutes until dissolved;
