Abstract

The invention discloses conducting silver aluminum slurry containing chlorobutanol. The conducting silver aluminum slurry comprises, by weight, 52-54 parts of A material, 10-15 parts of B material, 0.7-1.2 parts of di-n-octyl phthalate, 0.6-0.8 part of castor oil, 1.3-2.4 parts of organosilicon flatting agent and 1-2 parts of silane coupling agent KH580. The conducting slurry does not contain lead, completely meets the environment-friendly requirements, is applied to solar battery production and can be high in adhesion when formed on the surface of a solar battery, photoelectric conversion efficiency of the battery is high, silver powder of different grain diameters and the like are selected and used simultaneously, the contact area between grains is increased, and accordingly the conducting capability of the silver slurry is improved.

Description

technical field [0001] The invention relates to the field of conductive paste, in particular to a conductive silver-aluminum paste containing chlorobutanol. Background technique [0002] Conductive paste is the key material for packaging, electrodes and interconnection of electronic components, mainly including two categories: burn-in type conductive paste and curable conductive adhesive (conductive ink). [0003] Solar cell conductive paste is composed of silver powder, aluminum powder, etc., inorganic binder, organic carrier and related additives. In most electronic pastes, the inorganic binder is mainly low-melting lead-containing glass powder, which has major defects in environmental pollution and poor solderability. Therefore, the high efficiency, environmental protection and lead-free of conductive paste have become an inevitable trend. Contents of the invention [0004] The object of the present invention is to provide a conductive silver-aluminum paste containing...
