This invention discloses a microcapsule-modified self-healing mortar, its preparation method, and its application, belonging to the technical field of stone cultural relic protection and restoration materials. The microcapsule-modified self-healing mortar, by mass percentage, comprises the following dry materials: 50%-70% hydraulic lime, 12%-24% nano-kaolin, 15%-25% quartz sand, 0.05%-0.2% additives, and 0.25%-2% microcapsule powder; wherein the core material of the microcapsules in the microcapsule powder is tung oil, and the wall material is barium alginate. The microcapsule-modified self-healing mortar possesses high weather resistance, excellent compatibility, and long-term durable self-healing function. By introducing tung oil-barium alginate microcapsules, the microcapsule-modified self-healing mortar synergizes with traditional restoration mortar raw materials, enabling the mortar material to trigger active repair components in the early stages of deterioration, achieving self-healing and self-repair effects.
