Embodiment 1

[0020] A method for producing a 3D pattern on a glass surface, comprising the following steps: a. First cleaning the flat glass surface before and after tempering, and printing on the glass surface to be made with a 3D pattern by using a corrosion-resistant ink through a screen screen with a pattern designed in advance pattern, dry it, the surface of the back of the glass that does not need to be patterned is all silk-screened with corrosion-resistant ink, and dried;

[0021] b. Put the screen-printed glass into the etching solution according to the depth of the pattern. The composition and proportion of the etching solution are prepared by weight percentage, 75 parts of water, 5 parts of catalyst, 20 parts of hydrofluoric acid, and the temperature of the etching solution is constant. 27 degrees Celsius; the catalyst here uses a concentration of 65% sulfuric acid.

[0022] c. Take out the processed glass and put it into water to clean the etching solution on the glass;

Abstract

The invention discloses a method for producing 3D patterns on a glass surface. The method comprises the following steps: cleaning the surface of sheet glass before and after toughening, performing screen printing on patterns by using corrosion-resistant ink, putting the glass subjected to screen printing into etching solution, calculating the etching time according to the depth of the patterns and the rate of 0.01mm / 55-65seconds, taking out the processed glass, and putting the glass into water for cleaning the etching solution on the glass. The etching solution for the 3D patterns on the glass surface comprises the following components in parts by weight: 70-75 parts of water, 5-15 parts of a catalyst and 15-20 parts of hydrofluoric acid. The forming size of the patterns can be strictly controlled, so that the profile tolerance of the patterns is controlled to be + / -0.05mm.

Description

technical field [0001] The invention relates to a method for producing 3D patterns on the surface of glass and an etching solution used in the method. Background technique [0002] At present, there are two main types of glass surface patterns on the market: one is formed by hot pressing with a mold at high temperature. Although the hot-pressing pattern processing forms a pattern on the glass, the large tolerance of the pattern size makes it difficult to control the consistency of the pattern and the accuracy of the pattern. Transparency, low grade, poor effect. The other is to use laser to process the surface pattern, which can form a pattern with high precision. However, the processed pattern is opaque, and the edge of the pattern will be sawtoothed and chipped. And the edge collapse distance is greater than 0.03mm. Chinese invention application CN03119706.X discloses a production method for making matte three-dimensional patterned glass. This method also engraves patte...
