Problems solved by technology

[0002] At present, many iron and steel product processing enterprises only do simple degreasing and derusting treatment on the metal surface before processing and painting metal products, and do not do detailed chemical processing , It has buried hidden dangers for the future use of steel materials, that is, after half a year to one year of use, corrosion will begin to appear, which seriously affects the service life of steel materials
So there is a phosphating treatment agent on the market before the surface of the metal material is painted. It mainly puts the metal material into a phosphate solution containing manganese, iron, and zinc for chemical treatment, so that a metal surface is formed. A layer of phosphate protective film that is insoluble in water, but the phosphating technology has high operating temperature, unstable bath solution, high cost, and prone to sediment, which reduces the anti-corrosion performance of the phosphating film

[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;

[0045] 4) Add tartaric acid to the solution prepared in step 3 and stir for 2 to 3 minutes until dissolved;

[0046] 5) Add 20 parts of water to the solution prepared in step 4 and stir for 10-20 minutes.

[0047] The vitrified agent produced by this process has good stability, no sediment, and no phosphate. It can form a vitrified layer on the surface of steel, zinc and aluminum. It has strong binding force with various types of paint and is suitable for normal temperature. Unique spraying and immersion treatment, without heating equipme...

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. [0004] The technical s...
