Abstract

The invention discloses a conductive silver adhesive for shear-resistant composite LED packaging, and belongs to the technical field of photoelectric materials. According to the invention, 20 to 30 parts by weight of wood flour, 2 to 3 parts by weight of biogas slurry, 3 to 5 parts by weight of carbomer 941, 1 to 2 parts by weight of sucrose and 20 to 30 parts by weight of water are mixed and fermented, then ammonia water is dripped to adjust the pH value to 8.1 to 8.3, freeze-thaw cycles are carried out for 5 to 8 times, filtration, washing, drying and carbonization are carried out to obtaina modified additive; by ball milling, sieving and roasting of sepiolite, pretreated sepiolite is obtained, 20-30 parts of the pretreated sepiolite, 10-20 parts of a low melting point alloy and 2-3 parts of ferroferric oxide are mixed for ball milling to obtain modified sepiolite; and epoxy resin, a diluent, a curing agent, an accelerator, the modified additive, compounded silver powder, the modified sepiolite, plant essential oil and shell powder are stirred and mixed to obtain the conductive silver adhesive for shear-resistant composite LED packaging. The conductive silver adhesive for shear-resistant composite LED packaging has the characteristics of excellent conductive property and mechanical property.
