Abstract

The invention discloses low-temperature lead-free glass powder for a vehicle front windscreen laminated glass ink, and a preparation method thereof, wherein the low-temperature lead-free glass powder contains, by mass, 15-25% of SiO2, 45-60% of Bi2O3, 4-12% of ZnO, 1.5-4.0% of Na2O, 0.5-2.5% of K2O, 0.3-1.0% of Al2O3, 5-10% of B2O3, 0.4-1.3% of F2, 0.5-1.0% of TiO2, and 2.5-3.8% of ZrO2. The low-temperature lead-free glass powder of the present invention has characteristics of low softening temperature, wide softening temperature range, suitable expansion coefficient, high acid resistance, high alkali resistance, high adhesion, and the like.

Description

technical field [0001] The invention belongs to the field of lead-free glass powder, and in particular relates to a low-temperature lead-free glass powder used for the ink of laminated glass on the front of the automobile glass. Background technique [0002] Automotive toughened glass ink is used on the edges of the toughened glass of the car to effectively reduce the UV transmittance, prevent the chemical change of the glue used to bond the glass and the car body, and at the same time cover the conductive silver paste, giving the appearance of the car a sense of beauty Action ink. Automotive tempered glass ink is mainly composed of glass powder, black glass pigment, varnish, additives, etc. and formulated according to a certain proportion. The mass ratio of glass powder can generally reach about 60%-80%. As a binder, glass powder plays an important role in glass ink. The glass powder softens and melts during sintering to produce a liquid state. When the organic components...
