Heat-conducting weather-resistant anti-radiation protective film for display screen and preparation method of protective film

Abstract

The invention discloses a heat-conducting weather-resistant anti-radiation protective film for a display screen and a preparation method of the protective film. The protective film comprises, by weight, 20-30 parts of epoxy resin, 10-14 parts of polyurethane resin, 4-6 parts of modified silicon dioxide, 10-16 parts of methyl methacrylate, 10-12 parts of poly-ethyl silicate, 4-6 parts of ethyl acrylate, 8-10 parts of anti-radiation additives, 5-7 parts of nano additive, 10-16 parts of acid ester mixture, 4-6 parts of flame-retardant additive, 5-7 parts of processing aid and 2-3 parts of coupling agent. The protective film is excellent in mechanical property, glossiness, light transmittance and heat shrinkage performance, good in scratch resistance, uniform in heat dissipation, capable of preventing radiation and excellent in weather resistance, and has certain fireproof and flame-retardant performance. The preparation method is safe and reliable in raw material component, harmless to human bodies and environments, low in cost, simple in process, easy to operate, capable of achieving industrial production, high in practical value and good in application prospect, and the raw materials are easy to obtain.

Description

technical field [0001] The invention relates to the technical field of protective film materials, in particular to a heat-conducting, weather-resistant and radiation-resistant protective film for display screens and a preparation method thereof. Background technique [0002] With the popularity of electronic industry technology and its products, in order to effectively protect the paint surface or touch screen surface, a replaceable protective film layer is used on the surface to protect the paint surface or touch screen surface of the product. Nowadays, various protective films are also used in electronic products. Driven by the drive, it has gradually stepped up one step after another, favored by users, and more and more applied to the automotive field, furniture industry, electrical industry, electric power and other related industries and fields. Mobile phones, MP4, digital cameras, notebooks and other digital products and automobiles generally use plastic film to protec...

However, the anti-scratch effect of this kind of plastic film is poor. When it is scratched by general external force, it often leaves scratches and the display effect of the screen may affect the aesthetics of the product. It may damage the glass screen or car glass of digital products, so it cannot protect the glass screen or car glass of digital products well

[0003] At the same time, in the prior art, polyimide film is used in display screen film. Although polyimide film is sintered to obtain graphite heat sink, so as to be pasted on the heat source, it is limited by the product quality of polyimide film. The performance is uneven, which affects the heat dissipation performance of the heat dissipation double-sided film. There are the following technical problems: uneven heat dissipation, prone to local overheating of the tape, improving the product's unstable heat dissipation performance, poor reliability performance, and not conducive to product quality control. , affecting the competitiveness of the product

In order to prevent radiation damage to the human body, people have developed many radiation-proof materials, such as radiation-proof clothing, which can prevent radiation to a certain extent, but the existing radiation-proof methods only reduce radiation damage, and have not fundamentally reduce radiation dose
