Problems solved by technology

[0004] In glass color printing or etching printing, since the glass color glaze or glass frosting paste used is a medium with a certain particle size or viscosity, and is limited by the need for heating and sintering after printing or the number of printing screen mesh, screen printing is used. Plate printing is difficult to achieve in actual production
Others such as sandblasting, grinding and engraving, vertical color crystal method, etc. are even more unusable.

example 1

[0038] On the surface of the cleaned float glass, use a 250-mesh screen to coat the photosensitive resist ink as a photosensitive layer, and dry it in a dust-free oven at 80° C. for 15 minutes. Cover the surface of the ink layer with a 120 line / hour screen negative plate positive, vacuumize and press it, expose it under a 5000W iodine-gallium lamp for 0.5 minutes, spray and develop it with 5% sodium bicarbonate aqueous solution at 28°C for 2 minutes, and wash it. After drying, a master negative image consisting of an ink layer is formed on the glass surface. The glass with the negative image ink layer is hardened in an oven at 140°C for 15 minutes. After cooling, immerse in a commercially available glass frosting solution at room temperature and etch for 1 minute, then wash it, and spray it with 5% sodium hydroxide aqueous solution at 70°C. Remove the film for 5 minutes. After all the photosensitive ink layer on the glass surface is completely removed, wash and dry. Finally, ...

example 2

[0040]On the product surface that above-mentioned example 1 obtains, with 300 order silk screens, the black slow-drying gravure printing ink is fully coated on the pattern area, then scrapes off the ink adhering to the surface with a metal scraper against the glass surface of the pattern area. After drying, a black-and-white photo-effect art glass product with black ink filled in the frosted pits is obtained.

example 3

[0042] On the glass surface with indium oxide-tin (ITO) transparent conductive film sputtered on the surface, use the same process as Example 1 to form a negative image pattern made of photosensitive ink. After hardening the film, immerse the glass in the electroplating nickel tank, at 50℃, 2.5A / d m 2 Plating at a current density of 3 minutes, wash. After the film is removed, an art glass product whose surface has a pattern that is completely consistent with the image on the base plate composed of metal nickel plating points.

Abstract

A method of forming fine patterns on the surface of glass and glassware, suitable for the manufacture of art glass and glassware. The method is: (1) forming a photosensitive layer on the surface of glass or glass products. (2) Perform screen processing on the original image to make a master plate. (3) Expose the photosensitive layer with a screen master. (4) Develop, dry and harden the exposed glass or glass products. (5) Surface treatment of glass or glass products with photosensitive patterns on the surface by chemical or physical methods. (6) Remove the remaining photosensitive layer on the surface, wash and dry. The advantages of the present invention are: (1) The light and dark levels of the original image can be well reproduced on the surface of glass and glass products, and the original original can be reproduced faithfully. (2) No manual processing, suitable for mechanized mass production. (3) The processing cost is low.

Description

technical field [0001] A method of forming fine, photographic patterns on the surface of glass and glassware. The invention relates to a method for forming a photosensitive pattern on the surface of glass and glass products (hereinafter collectively referred to as glass) with a photosensitive protective film, and then performing chemical or physical surface treatment to produce a fine pattern with photo effect on the glass surface. Background technique [0002] The so-called art glass, which forms various patterns on the glass surface, is getting more and more applications in fields such as architecture, decoration, furniture, daily necessities, and artwork in recent years. At present, the manufacturing methods of art glass mainly include color printing method, etching printing method, sandblasting method, frosting method, grinding method, vertical color crystal method and so on. In these methods, due to the limitations of the processing technology, the processed patterns a...
