Problems solved by technology

The shell of electronic products is generally made of metal materials, and metal materials sometimes need to be processed at high temperatures. Ordinary metal surface coatings will be oxidized due to high temperature, which affects the appearance of the metal.
Existing high-temperature oxidation-resistant coatings for metals on the market are prone to precipitation, and do not have protective, anti-rust and anti-static properties

Abstract

The invention provides a high-temperature-oxidation-resistant coating for an electronic product and a preparation method thereof. The coating comprises the following components in parts by mass: 50-68 parts of nano titanium dioxide, 8-20 parts of aluminum oxide, 3-7 parts of sodium nitrite, 1.2-3 parts of magnesium oxide, 5-10 parts of feldspar powder, 5-10.5 parts of calcined high aluminum powder, 0.6-1.5 parts of ferrous oxide, 3-7 parts of ceramic micro powder, 0.1-0.23 part of spinel, 2-5 parts of liquid sodium silicate, 1-3 parts of water and 5-12 parts of a coating antistatic agent. The coating provided by the invention is fine in particles, does not precipitate easily, is high in high-temperature resistance and hardness, can be used for well protecting metal, and has antirust and antistatic performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-temperature oxidation-resistant coating for electronic products and a preparation method thereof. Background technique [0002] Nowadays, people's daily life is inseparable from electronic products, and there are various types of electronic products. The shells of electronic products are generally made of metal materials, and metal materials sometimes need to be processed at high temperatures. Ordinary metal surface coatings will be oxidized due to high temperature, which affects the appearance of the metal. Existing high-temperature oxidation-resistant coatings for metals on the market are prone to precipitation, and do not have protective, anti-rust and anti-static properties. Contents of the invention [0003] Technical problem to be solved: Aiming at the shortcomings of the above-mentioned high-temperature oxidation-resistant coating for metals, the present invention provide...
