Embodiment 1

[0007] The raw materials and mass percentages used are as follows: 6.5% fluozirconic acid, 0.1% fluotitanic acid, 1% tannic acid, 0.1% nitric acid with a mass concentration of 65%, 0.5% phytic acid, 0.1% citric acid, 1% hydrofluoric acid, Nickel nitrate 2%, ammonium bicarbonate 6% and water balance.

[0008] The preparation method is: first calculate and weigh the hydrofluoric acid and put it in the reaction kettle, then add the calculated and weighed water

[0009] Put into the reaction kettle and turn on the stirrer, set the speed at 60 rpm; then add the calculated and weighed fluozirconic acid, fluotitanic acid, tannic acid, nitric acid, phytic acid, citric acid, and nickel nitrate with a mass concentration of 65%. and ammonium bicarbonate were gradually added into the reaction kettle in turn, and stirred continuously for 1.5 to 2 hours, until the solution was light purple and transparent;

Embodiment 2

[0011] The raw materials and mass percentages used are as follows: 4.5% fluozirconic acid, 1% fluotitanic acid, 0.1% tannic acid, 0.5% nitric acid with a mass concentration of 65%, 0.1% phytic acid, 0.5% citric acid, 0.1% hydrofluoric acid, Nickel nitrate 3%, ammonium bicarbonate 4% and water balance.

[0012] The preparation method is the same as in Example 1. .

Embodiment 3

[0014] The raw materials and mass percentages used are as follows: 5% fluozirconic acid, 0.5% fluotitanic acid, 0.5% tannic acid, 0.3% nitric acid with a mass concentration of 65%, 0.3% phytic acid, 0.3% citric acid, 0.5% hydrofluoric acid, Nickel nitrate 2.5%, ammonium bicarbonate 5% and water balance.

[0015] The preparation method is the same as in Example 1. .

[0016] When in use, add water to Example 1, 2 or 3 of the present invention according to the mass percentage of 1-4% to prepare a working fluid, the pH value is 2.5-3.0, and the aluminum alloy profiles and plate workpieces are treated at room temperature for 30-90s. The various performance indexes of the obtained treated film meet the quality requirements of vitrified film, and the performance indexes are equivalent to imported products.

Abstract

The invention discloses a pre-coating non-chrome ceramic filming agent of an aluminum alloy profile and a sheet workpiece. The pre-coating non-chrome ceramic filming agent is characterized by being prepared from the following raw materials in percentage by mass: 4.5 to 6.5% of hexafluorozirconic acid with mass concentration of 50%, 0.1 to 1% of hexafluorotitanic acid with mass concentration of 40%, 0.1 to 1% of tannic acid, 0.1 to 0.5% of nitric acid with mass concentration of 65%, 0.1 to 0.5% of phytic acid, 0.1 to 0.5% of citric acid, 0.1 to 1% of hydrofluoric acid, 2 to 3% of nickel nitrate, 4 to 6% of ammonium bicarbonate, and the balance of water. The pre-coating non-chrome ceramic filming agent can be prepared under normal temperature without heating, so that the energy consumption can be decreased; the pre-coating non-chrome ceramic filming agent has the same film treating performance for the aluminum alloy profile and the sheet workpiece as imported products, accompanying with lower cost.

Description

technical field [0001] The invention relates to a metal vitrified film treatment agent, in particular to a chrome-free vitrified film forming agent for aluminum alloy profiles and plate workpieces with low cost and excellent performance before spraying and coating. Background technique [0002] The surface of metal components is caused by oil stains, floating rust, heavy rust, oxide scales and welding high-temperature oxides. Therefore, before spraying and coating processes, the above-mentioned oil scales are removed and most of them are treated by phosphate conversion. Form a layer of black, silver gray or colored phosphate conversion film (film) with a certain roughness, porosity and adsorption on the surface to enhance the corrosion resistance of the workpiece surface, improve the surface of the workpiece and the coating or other organic surface treatment Adhesion between layers. However, the existing phosphating treatment agents contain heavy metals and phosphates, etc....
