The invention discloses an environment-friendly cement self-repairing system, and its preparation method and application. The preparation method comprises the following steps: adding a shell curing agent into deionized water to prepare solution 1, adding an inorganic nano emulsifier into deionized water, ultrasonically dispersing, then adding polysaccharide-shell, and uniformly stirring to obtain emulsion polymerization aqueous phase; adding epoxy diluent into epoxy resin, and uniformly stirring; obtaining an emulsion polymerization oil phase; mixing the emulsion polymerization aqueous phase and emulsion polymerization oil phase, and stirring to obtain uniform emulsion; dropping the uniform emulsion into solution drop by drop by using pendant drop method, stirring until the droplets are shaped, then filtering, washing with deionized water, and drying to obtain self-repairing capsules; next, mixing with an environment-friendly curing agent to obtain an environment-friendly cement self-repairing system. The environment-friendly cement self-repairing system is green, nontoxic and harmless, has strong water absorption, can block tiny cracks by volume expansion when contacts with water, thus further enhances the cement self-repairing effect.
