Anti-reflection plastic film and preparation method thereof

Abstract

The invention discloses an anti-reflection plastic film. The film is formed by sequentially laminating a base material, a hard coating layer, a deposition layer and a wet method layer, wherein the hard coating layer covers the upper layer, the lower layer or the upper and lower layers of the base material; the deposition layer is formed by repeatedly and alternately depositing a high-refractive index deposition layer and a low-refractive index deposition layer which are sequentially and alternately laminated; and the high-refractive index deposition layer is formed on the upmost layer. A preparation method for the film comprises the following steps of: (a) preparing a hard coating layer composition; (b) coating the hard coating layer composition obtained in the step (a) onto one surface or two surfaces of the base material, and performing photopolymerization to form the hard coating layer; (c) sequentially and alternately coating the high-refractive index deposition layer and the lower-refractive index deposition layer on the hard coating layer by a vacuum deposition method, a sputtering method or an ion gold-plating method; (d) preparing polysiloxane oligomer; and (e) coating the polysiloxane oligomer obtained in the step (d) onto the high-refractive index deposition layer on the upmost layer by a wet deposition method. The film prepared by the technical scheme has high abrasion resistance, water resistance and chemical resistance, a good anti-reflection effect and excellent physical and chemical properties and can be suitable for various optical parts.

Description

technical field [0001] The invention belongs to the field of film materials, and in particular relates to an anti-reflection plastic film used for covering liquid crystal displays, CRT picture tube displays, plasma displays, and EL light-emitting diode display devices. Background technique [0002] In various display devices such as liquid crystal display (LCD, liquid crystal display) and plasma display (PDP, plasma display panel), anti-reflection plastic transparent sheets are usually used to prevent image quality degradation caused by image reflection. In addition, in mobile phone display screens, navigators, and touch panels using liquid crystal display devices, the requirements for high definition and high image quality are gradually increasing. However, in such liquid crystal display devices and plasma display devices, glare caused by reflection of external light is the biggest problem. [0003] In order to solve this phenomenon, anti-glare (anti-glare) coating is usua...

Problems solved by technology

However, in actual use, its anti-reflection effect is not good, not only weakens the mechanical strength of the coating film, but also reduces chemical properties such as weather resistance or water resistance, so it is urgently needed to improve
