Embodiment Construction

[0016] A silk screen etching process for glass products, comprising the following steps:

[0017] (1) Anti-corrosion printing material preparation: 300g beeswax, 1100ml alkyd varnish, 800ml kerosene;

[0018] (2) Dissolving: Put the resist printing material in step (1) into the container and heat it to dissolve,

[0019] Stir evenly;

[0020] (3) Filtration: filter the resist printing material in step (2) with gauze to obtain a resist film, and cool it to 15-20°C for use;

[0021] (4) Printing: Anti-corrosion printing of the anti-corrosion film in step (3) on the surface of the glass, using 220-260 mesh stainless steel screen for printing, and the processing time is 3 to 10 minutes;

[0022] (5) Post-processing: Step (4) After printing, place it for more than 24 hours, and wait for the resist film to dry completely for hydrofluoric acid etching.

[0023] Based on the above: adopt the technical scheme of the present invention, put rosin powder 50g, beeswax 500g, alkyd varnis...

Abstract

The invention discloses a silk-screen etching technology of glasswork and relates to the technical field of processing of glass. The technology comprises the following steps: putting colophony powder, beewax, alkyd varnish and kerosene in a vessel set over water, heating and dissolving the materials; fully and uniformly stirring the dissolved materials, filtering the dissolved materials with gauze; cooling the filtered materials to room temperature to carry out silk-screen etching of glasswork; after over 24 hours and finishing printing till a resist film is completely dry, eroding the resist film with hydrofluoric acid. The technical scheme replaces the traditional method of hot coating a wax layer or other fastness-enhanced materials on glass surface as an anti-corrosion layer, and is simple and convenient in etched decoration of glasswork, so that time and labor in printing and preparation are saved and the glasswork is high in quality.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a silk screen etching process for glass products. Background technique [0002] Etching decoration of glass products, in the past, was mostly hot-coated wax layer and other reinforcement materials on the glass surface as a resist layer, and then used needles, carving knives and other tools to carve pictures on this coating to expose the glass surface, and then Use a plastic clamp cotton ball dipped in hydrofluoric acid to wipe the etching on the graphic screen. During the operation, the air extraction device should be turned on, and the etching should be stopped when the etching reaches the required depth, and the processes such as lye neutralization and water washing should be carried out. This method is time-consuming, poor in quality and low in efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
