Flux for high acid resistance automotive glass printing ink and preparation method thereof

Abstract

The invention provides flux for high acid resistance automotive glass printing ink and a preparation method thereof. The base material of the flux comprises the following raw materials in parts by mass: 1 to 4 parts of lithium oxide, 0 to 3.5 parts of sodium oxide, 0 to 2 parts of potassium oxide, 1 to 4 parts of calcium oxide, 0.5 to 3 parts of magnesium oxide, 2 to 7 parts of boron oxide, 0.5 to3 parts of phosphorus pentoxide, 20 to 30 parts of silicon oxide, 1 to 5 parts of titanium oxide, 1 to 5 parts of zirconium oxide, 55 to 65 parts of lead oxide, and 2 to 5 parts of an applied acid proofing agent. The flux has a wide softening temperature range and a wide swelling coefficient range within a formula component, the range of the ratio of the flux to a toner is wide, and the formed printing ink can be fired into light and matt effects in different degrees. The glass printing ink prepared through the flux has a high hiding rate, a wide sintering temperature range and high adhesiveforce and weather resistance, and meanwhile has high acid resistance.

Description

technical field [0001] The invention relates to the technical field of high acid-resistant flux, in particular to a flux for high acid-resistant automotive glass ink and a preparation method thereof. Background technique [0002] Automobile glass ink is a kind of glass glaze printed on the surface of automobile glass through screen printing. A tightly bonded "film" of glass. It has the functions of reducing the transmittance of ultraviolet rays, increasing the friction between the glass and the rubber glue in the car, covering the conductive silver paste and decorating. [0003] With the advancement of glass ink technology and the continuous deterioration of the natural environment, domestic and foreign glass manufacturers have put forward higher requirements for the acid resistance of the glaze layer of glass ink. At present, domestic and foreign automotive tempered glass inks are mainly products of companies such as American Flow and Dutch Johnson Matthey. [0004] The ...
