Abstract

The invention discloses a low-temperature setting environment-friendly conductive silver paste which is characterized by comprising, by weight, 40-45 parts of silver powder, 2-3 parts of quartz, 3-5 parts of mica, 1.3-2.4 parts of p-toluenesulfonic acid, 0.4-0.9 part of copper naphthenate, 4-6 parts of diethylene glycol monoethyl ether acetate, 2-4 parts of linoleic acid, 2.1-3.4 parts of benzalkonii bromidum, 0.5-1.2 parts of palmitoleic acid, 30-35 parts of auxiliaries, and a proper amount of water. According to the low-temperature setting environment-friendly conductive silver paste, quartz is added to serve as a modification material, so that the weather resistance and abrasion resistance of the conductive silver paste are improved. The conductive silver paste obtained through technical formula improvement has the advantages of being low in setting temperature, stable in quality, light in toxicity, low in cost, and broad in application prospect.

Description

technical field [0001] The invention relates to the field of conductive silver paste, in particular to a low-temperature curing environment-friendly quartz conductive silver paste and a preparation 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, ha...
