Problems solved by technology

When the glass powder in the glass ink melts, the oxide with high melting point does not melt, and the elemental metal oxidizes into non-melting metal oxide or high-valent oxide, which will stay on the surface of the glaze layer, blocking the glaze layer and the glass mold cloth, These two methods can improve the anti-adhesive effect of glass ink to a certain extent. However, the addition of high melting point oxides will make the surface of the sintered glaze layer gray and affect the appearance. At the same time, the acid resistance will drop a lot; adding elemental metal or Sulfides will also reduce acid resistance, and sintering of sulfides will cause environmental pollution

Abstract

The invention provides automobile toughened glass ink, which is prepared from glass powder, inorganic pigment, varnish, a dispersing agent, a flatting agent and a thixotropic agent, wherein the glass powder is prepared from 74-85wt% of Bi2O3, 2-11wt% of SiO2, 2-11wt% of B2O3, 2-5wt% of Al2O3 and 2-5wt% of ZnO. The application also provides a preparation method and application of the automobile toughened glass ink. When the glass powder in the automobile toughened glass ink provided by the invention is sintered at the temperature of 600-700 DEG C, one or a plurality of silicate or borate crystal phases are easy to separate out; a dense crystallization layer enables the ink to have a good anti-sticking property and not to adhere to a mould, and enables the ink to have the advantages of being high in adhesive force and high in acid and alkali resistance, shielding conductive silver paste, resisting ultraviolet radiation, and the like.

Description

technical field [0001] The invention relates to the technical field of glass oil film, in particular to an automobile tempered glass ink and a preparation method thereof. Background technique [0002] Automotive tempered glass ink is coated on the surface of the glass to be tempered, so that the glass is sintered at the same time during the hot bending and tempering process at 600-700 ° C. In this process, the molten glaze must be able to withstand the bending mold The pressure of the glass glaze layer cannot be damaged and no traces of glaze can be left on the abrasive tool. Finally, a layer of inorganic glass film glass glaze is formed on the tempered glass of the car, which has the functions of decorating the car, reducing ultraviolet radiation, and shielding the conductive silver paste. , Improve the comfort and installation efficiency of the car. [0003] In order to prevent the glaze from adhering to the bending abrasive during the sintering process of the automotive ...
