GRAY CONDUCTIVE SILVER PASTE FOR AUTOMOTIVE GLASS AND PREPARATION METHOD THEREFOR

摘要

The prevent invention relates to a gray conductive silver paste for automotive glass and a preparation method therefor. Raw materials of the conductive silver paste are the following components in parts by weight: 50-70 parts of metal silver powder, 10 parts of metal nickel powder, 3-6 parts of glass powder, 2-8 parts of high-polymer resin, 0.5-1.5 parts of an organic additive, 0.5-4.5 parts of an inorganic additive, and 10-30 parts of an organic solvent. The conductive silver paste is ultimately obtained by steps such as (1) the formulation of a carrier, (2) the formulation of silver paste, and (3) the production of the silver paste. Compared with the prior art, the present invention can not only meet technical index requirements such as the conductivity, adhesion, tin side color, and black glaze matching property of a windshield of a coach, but also have anti-oxidation performance.
