Problems solved by technology

However, the imitation copper coating formed by this method has the following defects: (1) the substrate is an organic compound, the anti-aging performance and the bonding with glass are relatively low, the service life is less than 10 years, and it is easy to Peeling and discoloration; (2) The hardness of the coating is low, and it is easy to be scratched by hard objects during installation and use, which affects the decorative effect; (3) The preparation of tempered glass with imitation copper coating needs to be sprayed after tempering the glass And curing process, long process flow, low production and sales rate

Embodiment 1

[0032] (1) Weigh boric acid, vanadium pentoxide, zinc oxide, silicon dioxide, titanium dioxide, and bismuth trioxide according to the mass ratio of 18:8:5:9:4:56 and pour them into the corundum ball milling altar. The diameter is 600mm, and corundum balls are added according to the mass ratio of ball to material 0.5:1, among which corundum balls with a diameter of 50mm account for 30%, and corundum balls with a diameter of less than 50mm account for 70%. The rotation speed of the ball mill is 30r / min. The raw material was ball milled for 1.5 hours and then taken out to obtain the raw material for smelting glass base material.

[0033] (2) Heat the crucible furnace to 1100°C at a speed of 4°C / min, plug the plugging rod, and pour in the powder mixed in step (1), the volume of the powder poured in is 4 / 5 of the volume of the crucible , Put an enamel container filled with water at the outlet of the crucible furnace. When the furnace temperature rises to 1100°C again, keep the te...

Abstract

The invention discloses a preparation process of tempered glass with a surface being coated with a copper-based composite coating. The preparation process comprises the following steps: 1) cleaning and drying a glass substrate; 2) coating the glass substrate with the copper-based coating, allowing the glass to stand to dry the coating to obtained the coated glass; 3) performing thermal treatment to the coated glass at 630-670 DEG C at the increasing rate of 30-40 DEG C / min under a protective atmosphere, and maintaining the temperature for 5-7 min, and cooling the glass to obtain the tempered glass with surface being coated with a copper-based composite coating. By means of the process, an inorganic copper-based coating layer is formed on the surface of the sheet glass, wherein the coating is combined with the glass tightly and has smooth surface. The copper-based coating layer is made from inorganic materials, so that the chemical anti-corrosion performance of the coated tempered glass is better than that of organic copper-like coated tempered glass in the prior art, and hardness of the coated tempered glass is also higher than that of organic coated tempered glass. The tempered glass has stronger anti-scarping and anti-wear performances and has longer service life.

Description

technical field [0001] The invention relates to a preparation process of tempered glass covered with a copper-based composite coating. Background technique [0002] Toughened glass is one of the most commonly used building materials. The surface is sprayed with imitation copper coating. Toughened glass has a special metal copper luster, good decorative effect, low price, and strong personality. It is widely used in home decoration and curtain wall decoration. . The current copper-imitation coated tempered glass is first tempered, and then the organic copper-imitated coating is applied to the surface of the tempered glass by spraying, screen printing and rolling printing, etc. After the paint is cured, a beautiful and flat copper-like coating is formed on the surface of the tempered glass. However, the imitation copper coating formed by this method has the following defects: (1) the substrate is an organic compound, the anti-aging performance and the bonding with glass are ...
