Embodiment

[0022] As shown in the accompanying drawings, the method for making an aluminum mirror exempt from coating protective paint with a vacuum coating machine of the present invention may further comprise the steps:

[0023] (1) Clean and dry the glass, and then install it on the workpiece frame; cut the aluminum wire into a certain length and put it into the first group of tungsten evaporators on the workpiece frame; cut the titanium wire and the iron-chromium-aluminum alloy wire into A certain length is twisted and loaded into the second group of tungsten evaporators on the workpiece holder. Since the combination of the metal film and the glass surface mainly depends on the dispersion force, the cleanliness of the glass surface directly affects the adhesion of the metal film. For example, new glass can be cleaned with tap water and a nylon brush, and then cleaned with tap water and pure water respectively, and then sequentially Blow dry with cool and hot air. The above cleaning ...

Abstract

The invention discloses a method for manufacturing an aluminum mirror without being coated with protective paint by using a vacuum coating machine, which comprises the following steps: firstly, cleaning glass, and then, filling argon gas into a vacuum chamber; adjusting bombardment current to carry out ion bombardment on the glass, and then, carrying out vacuum pumping operation; opening a group of tungsten evaporator flash evaporation aluminum wires to form an aluminum metal film on the surface of the glass; and then, filling oxygen gas, and opening another group of tungsten evaporator flash evaporation titanium wires and iron-chromium-aluminum alloy wires to further form a layer of mixed film of metals of titanium, iron, chromium and aluminum and oxides thereof on the aluminum metal film, thereby separating the aluminum metal film from air and water to perform the protective effect. The method of the inveniton leads the aluminum mirror not need to be coated with protective paint by forming a layer of protective film on the aluminum metal film, thus the application field of the aluminum mirror can be widened; and meanwhile, because the metal film is coated in the vacuum chamber in the coating machine, the production process has environment protection and energy saving, and the industrial mass production can be realized.

Description

technical field [0001] The invention relates to a method for making glass, in particular to a method for making an aluminum mirror free of protective paint by using a vacuum coating machine. Background technique [0002] Aluminum mirrors, also known as aluminized mirrors, are usually processed by vacuum coating machines. The existing aluminum mirror adopts float glass as the original sheet, which is successively cleaned and polished, high-vacuum metal deposition aluminized, the first corrosion-resistant paint and dried, and the second waterproof and hardened paint and dried. And made. Because it does not consume precious metals and has low production costs, it is widely used in decoration and reflective materials. However, because aluminum is a kind of active metal, the aluminum film formed by evaporation is very thin and not dense enough, and it is easy to oxidize. It must be coated with one or two layers of protective paint for long-term use. Aluminum mirrors cannot use...
