DAMP-HEAT-RESISTANT AND HIGHLY RELIABLE CONDUCTIVE SILVER EPOXY ADHESIVE, METHOD FOR PREPARING SAME, AND APPLICATION THEREOF

摘要

The present invention provides a damp-heat-resistant and highly reliable conductive silver epoxy adhesive, a method for preparing same, and an application thereof. Considering the total weight of the damp-heat-resistant and highly reliable conductive silver epoxy adhesive as 100%, the damp-heat-resistant and highly reliable conductive silver epoxy adhesive is prepared from the following raw materials: 65-85% of metallic silver powder, 5.0-30% of epoxy resins, 1-15% of an active heterocyclic compound having a triazine structure, 0.5-10% of acrylic resin, 1.0-3.5% of a curing agent, 0.05-1.5% of an accelerator, and 0.01-3% of functional additives. The present invention further provides a method for preparing the conductive silver adhesive and an application thereof. The conductive silver adhesive prepared in the present invention has good conductive, mechanical, bonding and damp-heat resistant properties, can effectively alleviate the problem of the poor damp-heat resistant property of existing conductive silver adhesives and the problem of red zones occurring during the aging process, and meanwhile can significantly improve the reliability of device and product packaging.
