Abstract

The invention discloses a high-strength corrosion-resistant glass glaze for automobiles and a preparation method of the high-strength corrosion-resistant glass glaze, and relates to the field of glass glaze. A lead-free environment-friendly low-melting-point glass flux is prepared by researching a ternary glass system and introducing lead-free low-melting-point raw materials to serve as a glass binder, so that the melting temperature of the glass flux is reduced, low-melting-point glass powder is induced to crystallize when the automobile glass is tempered by pre-crystallizing the bismuth silicate crystal nucleus, the tempered glass glaze layer has good adhesion resistance and acid resistance, the copper chromite black is added as a black agent, the copper chromite black has good black hue, the advantages of excellent durability, high temperature resistance, very stable chemical properties, light resistance, weather resistance, acid-base resistance, solvent resistance, no migration, easy dispersion and the like are achieved, and the expansion coefficient can be regulated by introducing the low-expansion-coefficient raw material into the low-melting-point glass system so as to achieve the high adaptability with the automobile glass.

Description

technical field [0001] The invention relates to the field of glass glazes, in particular to a high-strength corrosion-resistant glass glaze for automobiles and a preparation method thereof. Background technique [0002] Automotive glass ink is a black glass paste printed on the edge of the windshield or the entire surface of the windshield. It is mainly composed of low-melting glass powder, inorganic pigments, varnishes, dispersants, leveling agents and other additives. Dispersed and milled. The ink is printed on the printing glass substrate by screen printing, after drying and sintering, the other components in the ink are basically volatilized and decomposed, and the low-melting point glass powder and inorganic pigment are melted and covered on the windshield to form a black glass ink layer. It can prevent the chemical change of the glue bonding the windshield and the car body, shield the conductive silver paste, decorate the appearance of the car and absorb ultraviolet r...
