The invention relates to a high-heat-conductivity epoxy resin electronic binding glue. The invention is characterized in that the high-heat-conductivity epoxy resin electronic binding glue is prepared by mixing 100 parts by weight of a component A and 5-12 parts by weight of an amine curing agent; and the component A is prepared from the following raw materials in parts by weight: 70-85 parts of spherical aluminum oxide powder, 10-20 parts of epoxy resin, 2-3.5 parts of reactive diluent, 2.5-5 parts of toughener, 0.2-1 part of thixotropic agent and 0.1-0.5 part of coupling agent. The spherical aluminum oxide of the binding glue provided by the invention has higher filling volume than non-spherical aluminum oxide, and high heat conductivity for solids, and can quickly dissipate heat accumulated in the heating components; the filler with high filling volume can lower the thermal expansion coefficient and volume shrinkage, and thus, the binding glue is very suitable for binding electronic components; and the price of the spherical aluminum oxide is lower than that of boron nitride (BN) or aluminium nitride (ALN), and thus, the binding glue provided by the invention has the advantage of low cost.
