Preparation method for outdoor colored decoration glass

Abstract

The invention relates to a preparation method for outdoor colored decoration glass, belonging to the field of glass manufacturing. The preparation method comprises the steps of printing a colored pattern on the surface of float glass by a high-precision screen printing machine and a high-temperature-resistant inorganic paint, conveying the float glass to a high-temperature drying channel for gradual heating to 580-700 DEG C to combine pigments with the glass, gradually cooling the float glass or conveying the float glass into a toughened furnace for heating under the high temperature of 580-700 DEG C, and blowing air through a fan to cool the float glass immediately so as to combine the pigments with the glass. The preparation method can be applied to batch production, so that the labor and the resources for toughening and then low-temperature pattern painting are greatly saved; the success rate and the efficiency are improved; the glass prepared by the preparation method has anti-scratching, dampproof and outdoor-ultraviolet-resistant effects, and can be toughened, thermally bent and cut; a 3D (third-dimensional) effect can be achieved when the glass is used as a ceramic tile, and a semi-transparent effect or a full-transparent effect is achieved; compared with the conventional glazed ceramic tile in the market, the outdoor colored decoration glass has the advantages that the toughened intensity is enhanced by 5-8 times.

Description

technical field [0001] The invention relates to a preparation method of outdoor colored glass, in particular to a preparation method of outdoor high-temperature cuttable / bendable / temperable colored decorative glass. Background technique [0002] At present, the decorative glass on the market is basically low temperature, and the paint temperature does not exceed 300 degrees. Most of them are used indoors. 1: There is a peculiar smell, whether it is before or after processing, the peculiar smell is very strong, especially the peculiar smell emitted during processing The impact on the surrounding environment is great, and the harm to workers is not small. Even after being baked at a temperature of 150-250 ℃, when it is decorated in the room in the future, it will slowly release the peculiar smell and last for several years. 2: Not waterproof, although modern ink and paint technology, the adhesion has been significantly improved, but it is easy to fall off when it encounters w...

AI Technical Summary

Problems solved by technology

2: Not waterproof, although modern ink and paint technology, the adhesion has been significantly improved, but it is easy to fall off when it encounters water outdoors, and it will peel off when it encounters southern weather (wet days) indoors

3: Not anti-ultraviolet, some of the current stained glass have been baked at a temperature of 150-250 ℃, but some of them will fade obviously after being placed outdoors for a week, and if they are slow, there will be different degrees in one or two years the fading

4: Easy to scratch, low-temperature baking varnish glass is easy to be scratched by keys or nails, especially when it is plastered for sanitation, it will become a big face after a long time, and it is easy to scratch during handling, processing and installation hurt

To sum up, the traditional low-temperature baking paint process is easy to scratch during installation or use, and can only be used in a dry and non-humid indoor environment for a short period of time. There will be a pollution process of odor release for several years. It is necessary to do tempering and hot bending first. In order to do surface pattern treatment, the process is more cumbersome
