Problems solved by technology

[0002] At present, in the existing production process for glass mosaics with matte effect, the mosaic body raw materials are usually dry-pressed to make a mosaic glass body, and then pickled after firing. Make the surface of the glass mosaic have a matte effect, but a lot of waste gas and waste water are often generated during the pickling process, which is likely to cause environmental pollution and affect the physical and mental health of employees. At the same time, the waste gas and waste water produced by pickling process The treatment makes the preparation cost greatly increased, thus limiting the production and application of matte glass mosaics, and if the surface of the pickled glass is directly decorated with inkjet, the color of the surface is unstable, distorted and prone to glaze defect problem

Abstract

The invention discloses a white glaze for a glass surface and a preparation process for glass mosaic. The water glaze comprises the following raw materials in percentage by mass: 72-82% of raw glass powder, 10-20% of waste glass powder, 4-6% of titanium dioxide, 0-0.5% of an auxiliary material and the balance of water, and the fineness of the white glaze is in a range of 250-300 meshes. Accordingto the white glaze used for the glass surface provided by the invention, effective recycling of the waste glass powder material is realized, the preparation cost is reduced, a matt glaze effect can beachieved, the whiteness is high, the glaze is uniform, the color development is more stable and brighter, the glaze is more smooth, the process is simpler and more energy-saving and environmentally friendly, and the production cost is low.

Description
