Abstract

The invention relates to a preparation method of an antiradiation paint for electronic products. The preparation method comprises the following preparation steps: a, dispersing polycarbonate, phenolic resins, barium stearate and a graphene modifying agent in deionized water, then adding an organic solvent, and stirring so as to obtain a mixture I; b, adding graphene, bisphenol A resins, a diluent solvent and hexamethylene tetramine to the mixture I, and stirring so as to obtain a mixture II; c, filtering the mixture II, taking filtrate, adding carboxymethyl cellulose, polyethylene glycol, organic bentonite and a room temperature curing agent to the filtrate, leading into CO2, and stirring so as to obtain a mixture III; and d, placing the mixture III into a water bath, and heating so as to obtain the antiradiation paint. The prepared paint disclosed by the invention is excellent in properties of adhesive force, bending strength, hardness, impact strength, water resistance and the like, and the antiradiation properties of the electronic products can be effectively strengthened.

Description

technical field [0001] The invention belongs to the technical field of paint production, and in particular relates to a preparation method of a radiation-proof paint used for electronic products. Background technique [0002] Coating is an important chemical building material. With the development of society, coating science and technology are changing with each passing day. In order to meet the needs of various high-tech and people's lives, the development of functional coatings with various special properties has great impact on social development and people's living standards. The improvement is of great significance. [0003] At present, the general methods for reducing electromagnetic radiation are: 1) plating a metal layer, 2) coating a paint layer containing metal powder, and 3) using an anti-electromagnetic radiation film. Although the above methods can reduce electromagnetic radiation to a certain extent, none of these methods can effectively control the electromag...
