Problems solved by technology

However, the radiation protection effect of the protective film prepared by this method is relatively limited, mainly because: 1) graphene has a large tendency to agglomerate in the coating system and cannot effectively disperse, which also affects the anti-radiation effect of its protective film. Radiation function; 2) Due to the surface tension between the water-soluble polyurethane emulsion system and the PET film, the coating is not easy to disperse and spread evenly on the PET film, which is not conducive to its film formation

Description

technical field [0001] The invention relates to a composite material, in particular to a graphene modifier, a graphene radiation-proof coating and a radiation-proof protective film. Background technique [0002] 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 electromagnetic radiation generated by the display screens in wearable electronic products, 3C electronic products, smart electronic products, automotive display components, and home appliance display components. shielding. [0003] Chinese patent document (CN103319999A) discloses a preparation method of a radiation protection film, which mainly consists of graphene and a film-forming material, and the radiation protection film is m...
