Manufacturing method of multi-layer colored glass plate

Abstract

The invention provides a manufacturing method of a multi-layer colored glass plate. The product is in panel structure of high-grade decorative household appliances in a laminated structure. The method comprises the following steps of: step one, selecting ultrawhite or ordinary float transparent glass with the thickness of 2-6mm, performing cutting, edging, tempering or hot bending to form a tempered flat plate or arc-bent glass as a glass base plate (1); step two, forming a colored plated film semitransparent film (2) through vacuum sputtering deposition on one surface of the glass base plate (1); step three, forming a silk-making layer (3) in a concave line brush pattern manner through subtraction on the colored plated film semitransparent film; step four, printing a metal colored screen printing colored surface layer (5) on the silk-making layer; and step five, screen-printing or roll-coating a bottom protective layer (6) on the metal colored screen printing colored surface layer (5). The product prepared with the manufacturing method disclosed by the invention has high and luxurious wiredrawing texture quality feeling of metal stainless steel, the front face of the product is resistant to scratch and impact and easy to clean, and the aging resistance of the back face is superior to that of stainless steel decorative panel of household appliances.

Description

technical field [0001] The invention relates to a method for manufacturing a glass plate, in particular to a glass coating layer brush-screen printing composite technology and a manufacturing method, and belongs to the fields of glass deep processing and home appliance panel manufacturing. Background technique [0002] Household appliance panels, especially refrigerators, air conditioners, washing machines, etc., used to use glazed tempered glass instead of plastic, aluminum and stainless steel. Compared with high-grade decorative stainless steel, colored glaze tempered glass has the advantages of frontal scratch resistance, impact resistance, easy cleaning, and aging resistance. There are differences, so there are fewer and fewer applications. At present, glass plates imitating metal are also used. The metal film is pasted on the back of the glass through an adhesive. However, the manufacturing cost of this glass plate is very high, and its physical and chemical resistance...

Compared with high-grade decorative stainless steel, colored glaze tempered glass has the advantages of frontal scratch resistance, impact resistance, easy cleaning, and aging resistance. There are differences, so there are fewer and fewer applications

At present, glass plates imitating metal are also used. The metal film is pasted on the back of the glass through an adhesive. However, the manufacturing cost of this glass plate is very high, and its physical and chemical resistance cannot meet the quality requirements. , the adhesive between the metal film and the glass plate is prone to yellowing, which affects the appearance of the product; and the adhesive is easy to lose its adhesiveness due to the intrusion of moisture, etc., the metal film and the glass plate are separated, and even from the glass plate fall off
