Abstract

The invention provides acid and alkali resistant automotive glass printing ink. The automotive glass printing ink comprises the following raw materials: epoxy resin, acrylic resin, amino resin, silica sol, glass powder, pigments, an emulsifier, a solvent, a dispersing agent, a flatting agent and a thickening agent. The preparation method comprises the following steps: mixing and grinding glass powder raw materials, heating in a high-temperature furnace, maintaining the temperature, casting molding and annealing the molten glass, and grinding the obtained bulk glass so as to obtain the glass powder; adding the epoxy resin, the acrylic resin, the amino resin and the silica sol into the solvent so as to obtain varnish; and finally, adding the obtained glass powder, the pigments, the emulsifier, the solvent, the dispersing agent, the flatting agent and the thickening agent into the obtained varnish, grinding, thereby obtaining the product. The automotive glass printing ink disclosed by the invention is prepared by matching the low-melting-point glass powder with the epoxy resin, the acrylic resin and the amino resin, and has excellent acid and alkali resistance.

Description

technical field [0001] The invention relates to the technical field of automobile glass ink, in particular to an acid and alkali-resistant automobile glass ink 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 ultravi...
