Multi-color photoelectric coating procedure and its products

Abstract

The invention discloses a preparation process of a multicolor photoelectric coating and its product. The main process is to anti-white print cleaned substrate of needed painting by lithographic printing so that pictorial is covered in the printed oil and the printed substrate placed on the coating machine for coating. Single color graphics tablet is obtained after the substrate coating on with printing of oil cleaned. Multicolor designs are obtained in a single substrate by the circulation of duplication and printing, coating and cleaning printing oil.

Description

technical field [0001] The invention relates to a multi-color photoelectric coating process and its products, especially a process for forming a multi-color photoelectric coating by chemical etching, which generally belongs to the application of photoelectric coating and is applied to the technical field of optical products. Background technique [0002] From the discovery of phenomena such as the surface of soap foam, the gap between glass surfaces, and the color reflected from oil slicks on the water surface, thin film optics has become a researched science, and with the development of vacuum technology, computers, control technology and materials in the 20th century Advances in technology have made the production of multilayer films a feasible fact and further commercial use. In today's field of optoelectronic technology, optical thin film technology has become a tool to control the spectrum of light beams. It can effectively change and control the spectral characteristic...

Problems solved by technology

[0006] (1) Laser Etching (Laser Etching): mainly by carbon dioxide (CO 2 ) laser light (10.6μm) is focused by the lens to generate high heat, after melting and vaporizing the coating material, the coating material is adsorbed and deposited on the substrate, so that the substrate produces a thin film and then forms the desired pattern, while the general Coating materials such as titanium dioxide (TiO 2 ) melting point (2000°C) and silicon dioxide (SiO 2 ) melting point (1700°C) is higher than the melting point of the substrate such as glass (700°C). The pattern on the surface will produce fuzzy fogging and poor light transmission, and the edges of the engraved and unengraved parts will make the adhesion of the film poor, and the film will fall off when used at high temperature, which will reduce the quality of the manufactured GOBO , which is also the main disadvantage of laser engraving. In addition, only one-color engraving can be performed on a single piece of glass at a time, which reduces the process efficiency. To form a multi-color pattern piece, multiple pieces of glass need to be glued together. However, the adhesive material used will affect the penetration rate of the GOBO sheet. In addition, the jigs required for multi-piece glass gluing will be relatively larger, and the way of multi-piece glass gluing will affect the positioning of the pattern. There will be deviations, and the multi-color pattern sheets produced by gluing will fall off under the use of high-power lights. Moreover, laser engraving equipment is more expensive, and its cost is the highest in comparison. Therefore, as long as there is Relevant laser etching equipment can produce GOBO products, but due to the high production cost and easy damage to the substrate, although products with GOBO effects can be produced, high-quality GOBO cannot be produced.

[0007] (2) Chemical etching (Etching): This is the most commonly used method in the industry at present. This method is mainly based on the melting of coating materials such
