Problems solved by technology

[0003] The cracking phenomenon of glass glaze is more prominent under high temperature conditions (above 300°C), and glass glaze is used in the field of packaging metal, especially the metal silver layer will inevitably undergo low-temperature sintering (sintering temperature below 1000°C), that is, low-temperature glaze , Most of the existing low-temperature glaze formulas use potassium, albite, or lead-containing systems. The former increases the expansion coefficient of the glaze and affects the use

Abstract

The invention discloses a method for preparing low-expansion, high-temperature-resistant, environment-friendly, medium- and low-temperature transparent glass glaze. The preparation method comprises the following steps: batching; mixed grinding, dry ball milling for 6 hours; firing frit; making glass powder and drying ; Glaze making, mixing 60wt% of glass powder and 40wt% of organic vehicle in step (4), and then ball milling the mixture of glass powder and organic vehicle for 2H; printing; firing glaze; inspecting the appearance. The preparation method of the low-expansion, high-temperature-resistant, environment-friendly, medium-low temperature transparent glass glaze improves the effect of the close bonding between the glass glaze and the substrate, avoids problems such as cracking and peeling, and at the same time improves the toughness of the glass glaze, thereby improving the mechanical strength of the product. Improve the surface mechanical properties and thermal properties, while improving the stability of the glass glaze after manufacture, improve the quality of the glass glaze, reduce the expansion coefficient, reduce the defective rate of the entire glass glaze production, meet the requirements of environmental friendliness, and be suitable for manufacturing.

Description

technical field [0001] The invention relates to a preparation method of a low-expansion and high-temperature-resistant environment-friendly medium-low temperature transparent glass glaze, in particular to a preparation method of a low-expansion and high-temperature resistant environment-friendly medium-low temperature transparent glass glaze, which belongs to the technical field of packaging metal applications. Background technique [0002] Glaze is a thin layer of vitreous body applied on the surface of the product. The purpose is to improve the physical and chemical properties of the product surface and the mechanical properties of the product, and to decorate the surface of the product. It is more and more widely used in the field of product surface packaging and protection. [0003] The cracking phenomenon of glass glaze is more prominent under high temperature conditions (above 300°C), and glass glaze is used in the field of packaging metal, especially the metal silver l...
