Abstract

The invention provides conductive silver paste and a preparation method thereof. The conductive silver paste contains silver powder, alloy powder, resin and a coupling agent, the preparation process comprises the following steps: dissolving resin in a diluent to form a resin solution; adding the rest components into the resin solution, and uniformly stirring and mixing to obtain slurry; and grinding the paste by using a three-roller machine to obtain the conductive silver paste. The conductive silver paste takes silver powder as a matrix, and has the characteristics of conductivity, scratch resistance, hardness, solvent resistance, low cost and the like.

Description

Technical field: [0001] The invention relates to the technical field of conductive ink, in particular to a conductive silver paste and a preparation method thereof. Background technique: [0002] With the advent of the 5G era, the requirements for the use of mobile phones are getting higher and higher. At present, the back cover of the mobile phone is usually made of glass to enhance the mobile phone signal. In order to obtain a gorgeous appearance effect on the back cover of the mobile phone, a decorative film is usually attached to the inner side of the glass casing, and conductive silver paste is printed on the decorative film. The conductive silver paste has obvious effects on the enhancement of mobile phone signals. [0003] Conductive silver paste is a special functional material, generally composed of conductive functional phase, matrix resin binder phase, solvent and other auxiliary agents. The conductive functional phase is mostly conductive metal powder, while th...
