Preparation method of ethyl cellulose two-component microcapsule based on ZIF-8 modification

The invention discloses a preparation method of a ZIF-8 modified ethyl cellulose two-component microcapsule, ZIF-8 is prepared and wrapped to obtain a self-repairing microcapsule, and the pore structure of ZIF-8 can provide larger surface area and pore volume, so that more epoxy resin is accommodated, the drug loading capacity of the microcapsule is further improved, and the self-repairing microcapsule has the advantages that the self-repairing microcapsule is prepared; the self-repairing effect of the concrete is more durable; the ZIF-8 can realize accurate release control by adjusting the structure of the wall material, and can adjust the release rate and opportunity of epoxy resin according to the degree and requirement of concrete cracks, thereby more accurately realizing self-repairing; the ZIF-8 can provide an additional protective layer to protect the epoxy resin from being influenced by the external environment, so that the stability of the epoxy resin in the microcapsule is enhanced, and the epoxy re
