Abstract

The invention discloses a scratching-prevention PC (poly carbonate) film for an optical display screen. The scratching-prevention PC film for the optical display screen is obtained by the following steps of: curing an acrylate coating by a layer of ultraviolet light with the thickness being 1-5 microns on the surface of the PC film by taking the PC film as a base material; coating a coating material comprising 1-20 parts of a photoinitiator, 5-95 parts of acrylate, 0-90 parts of a diluent and 0-10 parts of an inorganic nano filler on the surface of the PC film; and curing through the ultraviolet light. According to the scratching-prevention PC film, the problems that the existing PC film is poor in hardness, and is limited in abrasion resistance and scratching resistance are solved; meanwhile the favorable flexibility and transparent performance of the film are endowed, so that the scratching-prevention PC film for the optical display screen is suitable for high-end photoelectric products such as laptops, plasma televisions, mobile phones and digital cameras.

Description

technical field [0001] The invention relates to an anti-scratch PC film for optical display screens and a preparation method thereof. Background technique [0002] PC film (polycarbonate film) has excellent optical properties, electrical properties and thermal properties, etc., and can be widely used in various electronic display screens, especially in plasma displays (PDP) and thin-film liquid crystal displays (LCD) in recent years. In-screen apps are particularly prominent. However, affected by the use conditions of optoelectronic products, the service life of PC films is very short, and the scratch resistance of its surface cannot meet the requirements of optoelectronic product screens. Contents of the invention [0003] The object of the present invention is to solve the problem of poor scratch resistance of existing PC films, and to provide a scratch-resistant PC film. [0004] The technical scheme adopted by the present invention to realize the above object is as f...
