Abstract

The invention discloses a preparation method of aluminum alloy car instrument panel surface enamel. The preparation method comprises the following steps that (1), the aluminum alloy car instrument panel surface formed through preparation is placed into an electrolytic bath after being subjected to decontamination and grease removal treatment for anodic oxidation treatment; (2), silicon oxide, titanium oxide, sodium oxide, potassium oxide, zirconium oxide, potassium fluoborate, vanadium oxide and water are added into a planetary ball mill and subjected to ball milling treatment for 100-120 min,and then enamel glaze is obtained; and (3), the prepared enamel glaze prepared in the step (2) is sprayed on the aluminum alloy car instrument panel surface treated in the step (1), the sprayed aluminum alloy car instrument panel surface is placed into a drying oven to be dried and subjected to high-temperature sintering, and a finished product is prepared. According to the preparation method ofthe aluminum alloy car instrument panel surface enamel, operation is easy, the cost is low, the surface of a prepared aluminum alloy car instrument panel has excellent oxidation resistance and corrosion resistance, the instrument panel is high in glossiness and fashion sense, and the quality of the instrument panel is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of automobile dashboards, and in particular relates to a method for preparing aluminum alloy automobile dashboard surface enamel. Background technique [0002] The instruments on the dashboard of different cars are not the same, but the conventional instruments of a general car include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. In modern cars, the car instrument also needs to be equipped with a voltage stabilizer, which is specially used to stabilize the voltage of the meter power supply and suppress the fluctuation range to ensure the accuracy of the car meter. Automobile instrument is an important part of automobile interior, which not only needs to have powerful functions and richer display content, but also needs to have an aesthetic appearance. In the prior art, in order to endow the automobile instrument with a sense of technolo...
