Abstract

The invention belongs to the technical field of radiation protective paint and in particular relates to high-temperature-resistant radiation protective paint for electronic products. The paint is formed by high-temperature-resistant slurry and a wave-absorbing radiation-proof material, wherein the high-temperature-resistant slurry contains the following components: ethanol, ethyl ether, iron powder, ferro-silicon-aluminum powder, nickel / iron powder, copper powder, nitrocellulose, potassium silicate and butyl acetate; and the wave-absorbing radiation-proof material contains the following components in parts by mass: molybdenum disulfide, graphene oxide, silicon carbide, nanometer aluminum oxide, titanium dioxide, an adhesive and deionized water. The processed paint is subjected to ball-milling treatment and ultrasonic dispersion, so that the paint is uniform in property, excellent in film-forming effect and high in film adhesion force; and moreover, the paint has excellent radiation protective effect and high-temperature-resistant characteristics.

Description

technical field [0001] The invention belongs to the technical field of anti-radiation coatings, in particular to a high-temperature-resistant anti-radiation coating for electronic products. Background technique [0002] With the continuous development of technology, all kinds of electronic products are flooding around us, including personal mobile communication devices, smart home appliances and other industrial electronic devices. These devices provide us with a more convenient life, but at the same time they also bring stronger electromagnetic radiation. Electromagnetic radiation refers to the phenomenon that electromagnetic waves generated by the interactive changes of electric and magnetic fields are emitted or leaked into the air. This phenomenon is inevitable today, but if the intensity of electromagnetic radiation is too large, it may cause harm to human health. [0003] At present, in the production process of many electronic equipment and electrical equipment, it i...
