Polymer mineral joint mixture as well as preparation method and use method thereof

The invention discloses a polymeric mineral joint mixture as well as a preparation method and a use method thereof, and belongs to the technical field of bolt protection. The polymeric mineral joint mixture comprises epoxy resin for a primer, an amine curing agent for the primer, and a surface glue; the surface glue comprises aluminum oxide filled epoxy resin and an amine curing agent for the surface glue; and the mass ratio of the epoxy resin for the primer to the amine curing agent for the primer flue to the aluminum oxide filled epoxy resin to the amine curing agent for the surface glue is (3-4):(2-2.5):(15-19):(7-9). The use method comprises the steps: firstly coating a primer mixture on the surface of a to-be-coated area, then continuously filling the primer mixture with the surface glue mixture, compacting, troweling, and finally curing to finish the coating use of the polymeric mineral joint mixture. The polymeric mineral joint mixture has the advantages of good plasticity and high bonding strength. 本发
