Abstract

The invention relates to a vacuum coating preparation method of an aviation organic glass (polymethylmethacrylate). A set of electronic beam evaporation and ion assisted vacuum coating device is used for continuously preparing a structure of three layers of (auxiliary-main-auxiliary) deposition film series, wherein two auxiliary film layers are respectively located on the bottom layer and the upper layer of a main film layer. The two auxiliary film layers are obtained by heating polytetrafluoroethylene resin liquid, evaporating and vaporizing, spraying into a vacuum chamber, ionizing under ion bombardment, and respectively depositing on the surface of the substrate and above the main film layer. The main film layer is deposited on a bottom layer film by film material (one of zirconium dioxide or hafnium oxide) under electronic beam evaporation and ion assisted bombardment so as to form an optical antireflection film. According to the invention, the structure of three layers of films, which is continuously prepared in vacuum, has the characteristics of high adhesion, high light transmissivity, low haze, friction resistance, weak acid and weak base corrosion resistance and the like. The preparation method provided by the invention is further suitable for vacuum coating of polycarbonate (PC) resin, and can be widely applied in industries of aviation, automobiles, car light outer covers and the like.

Description

technical field [0001] The invention relates to a preparation method of synthetic resin vacuum coating film, in particular to a preparation method of aviation plexiglass (polymethyl methacrylate) vacuum coating film. Background technique [0002] The vacuum coating of aviation plexiglass (polymethyl methacrylate) and acrylic resin (PC) materials is more and more used in the observation windows of aircraft cabins, auto parts and lamp covers. The advantages of this type of material are light weight, good transparency, and no cracking by impact, but the disadvantage is that the surface hardness is low, easy to scratch and not resistant to abrasion. Vacuum coating on the surface is an effective treatment method to improve its performance. However, the traditional vacuum coating process often leads to low adhesion strength between the surface of aviation plexiglass and the vacuum coating film, and the film layer is easy to peel off. This problem has been puzzling people, limiti...
