Abstract

The invention discloses weldable conductive silver paste and a preparation method and use thereof. The weldable conductive silver paste is prepared from the following materials in parts by weight: 40-60 parts of super-fine silver powder, 5-10 parts of flake-shaped silver powder 2-5 parts of calcium oxide, 3-8 parts of titanium oxide, 1-5 parts of aluminium oxide, 5-10 parts of silicon oxide, 2-4 parts of zirconium oxide, 1.3 parts of barium oxide, 0.5-2 parts of boric acid, 10-20 parts of terpilenol, 20-40 parts of butyl carbitol, 10-20 parts of tributyl citrate and 1-5 parts of ethyl cellulose. The silver paste electrode obtained in the invention is mainly used for the power connecting lead electrode of an electric heating film, such as a thick film, a printing film or a nanometer electric heating film and is higher in conductivity; and the printing electrode can be smaller, and can be directly welded with an electric wire lead with firmer wire connection.
