Epoxy resin adhesive for adhering ceramic-based grinding block to metal matrix, as well as preparation method and application thereof

The invention discloses an epoxy resin adhesive for adhering a ceramic-based grinding block to a metal matrix, as well as a preparation method and application thereof. The epoxy resin adhesive for adhering the ceramic-based grinding block to the metal matrix is prepared from the following components in parts by weight: 40 to 50 parts of epoxy resin E-51, 16 to 25 parts of epoxy resin E-44, 12 to 15 parts of a curing agent 593, 7 to 10 parts of polyamide 650, 5 to 9.3 parts of a diluent AGE, 0.5 to 1 part of a dispersing agent BYK-D410, 0.2 to 1 part of gas phase silicon oxide and 2 to 6 parts of white fused alumina powder. According to the epoxy resin adhesive for adhering the ceramic-based grinding block to the metal matrix, the raw materials are readily available, the process is simple, the cost is relatively low, and the adhesive force and the wear resistance are high. When the epoxy resin adhesive is used for adhering the ceramic-based grinding block to the metal matrix, the phenomena of falling off and e
