Abstract
The invention discloses conductive silver paste and a preparation method and application thereof, and belongs to the technical field of material chemical industry. The conductive silver paste comprises the following components in parts by mass: 40-90 parts of metal conductive powder, 5-60 parts of resin, 0-10 parts of a curing agent, 0.001-2 parts of an auxiliary agent and 5-50 parts of a solvent, the resin is polyamide-imide resin, and the curing agent is at least one of an epoxy resin curing agent and a polyisocyanate curing agent. The conductive silver paste can be prepared by fully grinding and uniformly mixing the components on a three-roller grinder. The silver paste has the characteristics of low silver powder content and high conductivity, the cost is greatly reduced, and the silver paste has a wide industrial application prospect.
Description
A kind of conductive silver paste and its preparation method and application technical field The present invention relates to material chemical technology field, specifically, relate to a kind of conductive silver paste and preparation method thereof and application use. Background technique With the development of industrial technology, the rapid development of electronic information industry and solar energy industry, conductive silver paste is An important material is widely used in cutting-edge fields such as electronic labels, membrane switches, touch screens, printed circuits and photoelectric conversion. area. Among them, conductive silver paste has been widely used in the field of solar photovoltaic power generation. Silver conductive paste is divided into two categories: 1. polymer silver conductive paste (drying or curing into film, with organic polymer as Adhesive phase); ② sintered silver conductive paste (sintered to form a film, sintering temperature...
