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.
