Abstract

The invention discloses carbon nano tube conductive silver paste for a filter. The carbon nano tube conductive silver paste is characterized by being composed of the following raw materials, by weight, 40-50 parts of silver powder, 3-4 parts of carbon nano tubes, 1-2 parts of boric oxide, 2.1-3.4 parts of precipitated barium sulphate, 0.4-0.9 part of sodium zirconate, 0.2-0.4 part of a titanate coupling agent, 0.4-0.7 part of sodium diacetate, 1.2-2.3 parts of methylimidazoline, 4-6 parts of ethylene glycol butyl ether, 3-5 parts of acrylic resin, 30-40 parts of assistants and appropriate water. Various effective constituents are combined in an optimized mode, the production process is simplified, and compared with the prior art, implementation and operation are convenient, after a substrate is coated with the carbon nano tube conductive silver paste for the filter and sintered, a silver conductive layer which is high in compactness, high in adhesive force, good in conductive performance and good in weldability is formed, and the market prospects are wide.

Description

technical field [0001] The invention relates to the field of conductive silver paste, in particular to a carbon nanotube conductive silver paste for filters and a manufacturing method thereof. Background technique [0002] Conductive silver paste refers to the silver paste printed on the conductive substrate to make it have the ability to conduct current and eliminate the accumulated static charge. It is generally printed on non-conductive substrates such as plastic, glass, ceramics or cardboard. It is made of conductive Filler, binder, solvent and additive composition. The characteristics that conductive silver paste needs to have are: good conductivity (antistatic property), strong adhesion, good printing adaptability and excellent solvent resistance. However, the existing conductive silver paste on the market has many shortcomings, not only containing lead , cadmium, etc., are toxic, pollute the environment, and when used on conductive substrates, have low adhesion, poor...
