Abstract

The invention relates to relates to the technical fields of lead-cadmium-free glass powder and printing ink and particularly relates to lead-cadmium-free compound glass powder for printing ink for a windshield of an automobile. The lead-cadmium-free compound glass powder is characterized by being prepared by adequately mixing Bi2O3-B2O3-SiO2 system glass powder with Nb2O5-ZnO-B2O3-SiO2 system glass powder in a mass ratio of (2-5) to 1, wherein the Bi2O3-B2O3-SiO2 system glass powder comprises the following components in percentage by weight: 10%-45% of Bi2O3, 8%-30% of B2O3, 20%-50% of SiO2, 3%-15% of ZnO, 2%-8% of Na2O and 2%-8% of K2O; and the Nb2O5-ZnO-B2O3-SiO2 system glass powder comprises the following components in percentage by weight: 8%-22% of Nb2O5, 10%-30% of ZnO, 20%-45% of SiO2, 6%-20% of B2O3, 0.5%-4% of MoO3, 0.5%-4% of TiO2, 5%-15% of Na2O, 0.2%-2% of K2O, 1%-5% of Li2O, 0.2%-2% of ZrO2 and 0.2%-2% of Al2O3. The prepared compound glass powder is applied to the printing ink for the windshield of the automobile, so that the printing ink can be adequately fused at 600-650 DEG C in a sintering process, does not crack, is good in glossiness and high in blackness and further has excellent water resistance and acid-base corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of lead-free cadmium glass powder and the technical field of ink, in particular to a lead-free cadmium composite glass powder for automobile windshield screen printing ink and a preparation method thereof. Background technique [0002] Automobile windshield ink is coated on the surface of the automobile windshield and subjected to high-temperature bending treatment at 600-700°C, which can effectively reduce the ultraviolet transmittance and prevent the chemical change of the glue used to bond the glass and the car body. Conductive silver paste and products that decorate the appearance of the car body. The rapid development of the automobile industry and the increasing requirements of people for environmental living standards have increased the demand for automotive windshield inks and increased the performance requirements for inks. [0003] Low-melting point glass powder is one of the main components for t...
