Polycalcium ion superabsorbent fiber cement-based self-repairing material and preparation method thereof

The invention discloses a poly calcium ion super absorbent fiber cement-based self-repairing material and a preparation method thereof, and the poly calcium ion super absorbent fiber cement-based self-repairing material comprises the following components by mass: 500-1000 parts of cement, 230-460 parts of water, and 2-6 parts of poly Ca ion super absorbent fiber; the poly Ca ion super-absorbent fiber is resin obtained by mixing and polymerizing acrylic acid and acrylate with super-absorbent fiber under the action of a cross-linking agent; and carrying out alkaline hydrolysis on the obtained resin. The cement-based self-repairing material has high calcium ion adsorption capacity, after a large number of calcium ions are adsorbed, high-concentration calcium ions accelerate the reaction with water and carbon dioxide in air, so that calcium carbonate is generated to reinforce cracks, the integrity of fibers can be kept, and a good self-repairing effect can be achieved in the cement-based material. 本发明公开了一种聚钙离子超吸水
