High-temperature metal wire drawing screen printing process

Abstract

The invention relates to a high-temperature metal wire drawing screen printing process, and belongs to the technical field of glass product manufacturing. The high-temperature metal wire drawing screen printing process comprises the following steps of respectively designing printed patterns of the drawing color, the main color and the background color by a computer; printing films according to theprinted patterns; manufacturing a screen printing screen board by using the films; placing light plate glass on a table board of a screen printing machine; respectively printing the printed patternson a printing surface of the light plate glass through the screen printing screen board to form a drawing layer, a main color layer and a background layer; then placing the glass into a horizontal continuous tempering furnace for heating and tempering, wherein the tempering temperature is 680 to 690 DEG C, the tempering time is 150 to 180S, so that ink of the drawing color, the main color and thebackground color and the glass are sintered into a whole; and carrying out cooling, secondary cleaning and packaging on the product. According to the high-temperature metal wire drawing screen printing process provided by the invention, the product is delicate in color, the formed drawing is as thin as hair, the ink and the glass are sintered into a whole, the product is not easy to fall off, thedurability is high, the texture is better, and the product is more attractive and higher in grade.

Description

technical field [0001] The invention belongs to the technical field of glass product manufacturing, and in particular relates to a high-temperature metal wire drawing and silk screen printing process. Background technique [0002] The metal wire drawing process is widely used on the back shell of mobile phones. Metal wire drawing can clearly show every tiny silk mark, so that the fine hair luster appears in the metal matte, so as to play the role of beauty and anti-corrosion, so that the product has both fashion and technology elements. Applying metal wire drawing to the technical field of home appliance glass product manufacturing can make home appliance glass products more textured, and the aesthetics can be significantly improved. In the prior art, the wire drawing and screen printing process of glass products is carried out at a temperature of about 180°C.
