Abstract

The invention relates to the technical field of lead-free cadmium glass powder and the technical field of ink. A lead-free cadmium composite glass powder for automobile windshield ink, which is characterized in that the composite glass powder is composed of Bi2O3-B2O3-SiO2 system glass powder and Nb2O5-ZnO-B2O3-SiO2 system glass powder according to the ratio of 2~5:1 Mass ratio is fully mixed. The components and mass percentages of the Bi2O3-B2O3-SiO2 system glass powder are: 10%~45%Bi2O3, 8%~30%B2O3, 20%~50%SiO2, 3%~15%ZnO, 2% ~8%Na2O, 2%~8%K2O. The components and mass percentages of the Nb2O5-ZnO-B2O3-SiO2 system glass powder are: 8%~22%Nb2O5, 10%~30%ZnO, 20%~45%SiO2, 6%~20%B2O3, 0.5%~4%MoO3, 0.5%~4%TiO2, 5%~15%Na2O, 0.2%~2%K2O, 1%~5%Li2O, 0.2%~2%ZrO2, 0.2%~2%Al2O3. The obtained composite glass powder is used in automobile windshield ink, so that the ink can be fully melted and not cracked during the sintering process at 600℃~650℃, with good gloss and high blackness. The ink also has excellent water resistance, acid and alkali 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...
