Abstract

The invention provides a computer anti-radiation film material and a preparation method thereof. The computer anti-radiation film material is prepared from the following components: polycarbonate, modified kaolin, barite powder, cellulose, titanium dioxide, mica powder, zinc ore, calcium carbonate, graphene, composite emulsion, polypropylene glycol, a coalescing agent, an additive, a thickener anddeionized water. The anti-radiation film material prepared by the preparation method provided by the invention not only can greatly improve the anti-radiation effect to reduce harm to human body caused by radiation, but also has the characteristics of waterproofing property, high permeability and relatively good heat dissipation effect; moreover, the anti-radiation film material guarantees normalrunning of a computer, offers safety guarantee for the computer user, and effectively reduces the harm caused by radiation, and thus has relatively high value in use.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a radiation-proof film material for computers and a preparation method thereof. Background technique [0002] After entering the 21st century, the rapid development and popularization of computers, the electromagnetic radiation light generated by computers poses a great threat to human health, and has attracted more and more people's attention. Although there are a variety of functional computer protective films on the market, most of the computer protective films are polymer polymer films such as PE and PVDC synthesized from petrochemical materials, which have many problems such as energy consumption and environmental pollution. If the screen is scratched or cracked, although it has good dust and scratch resistance, it does not have radiation protection. [0003] Most of the existing computer display screens are LED, and the screen is large, but many users who use...
