AI Technical Summary

Technical Problem

Existing seamless flooring materials cannot automatically heal after microcracks occur, leading to continuous degradation of structural performance. Repair methods are passive and costly, repair materials have poor compatibility with the substrate, repair timing is difficult to grasp, and the ability to be repeatedly repaired is limited.

Method used

A ternary microcapsule self-healing system, including type A, type B, and type C capsules, is adopted. By pre-embedding functional microcapsules in the cement matrix, automatic detection and self-healing of microcracks are achieved. Dual repair is carried out by epoxy-amine curing reaction and nano-CaCO3 mineralization reaction. Combined with low-shear process and optimized mix ratio, the integrity of the capsules and the repair effect are ensured.

Benefits of technology

It enables automatic detection and self-healing of microcracks, improving the service life of the floor, reducing maintenance costs, enhancing the durability and reliability of the repair effect, and adapting to multiple accumulations of micro-damage throughout the entire life cycle of the floor.

Abstract

The invention belongs to the technical field of terrace materials, and particularly relates to a self-healing seamless terrace material based on a microcapsule self-repairing technology and a preparation method and a construction method of the self-healing seamless terrace material. The invention discloses a self-healing seamless terrace material based on a microcapsule self-repairing technology. The self-healing seamless terrace material comprises a high-performance cement matrix and a ternary microcapsule self-repairing system, the high-performance cement matrix is prepared from cement, fly ash, silica fume, quartz sand, PVA fibers and a high-efficiency water reducing agent, and the ternary microcapsule self-repairing system comprises an A-type capsule, a B-type capsule and a C-type capsule; wherein the capsule core of the A-type capsule is an epoxy resin prepolymer, the capsule wall of the A-type capsule is urea resin, the particle size is 50-100 microns, and the volume mixing amount is 3-5%, the capsule core of the B-type capsule is an amine curing agent and a catalyst, the capsule wall of the B-type capsule is polyurethane or polyurea, the particle size is 30-80 microns, and the volume mixing amount is 2-4%. The capsule core of the C-type capsule is a nano calcium carbonate suspension, the capsule wall is gelatin or Arabic gum, the particle size is 20-50 microns, and the volume mixing amount is 1-2%. According to the self-healing seamless terrace material based on the microcapsule self-repairing technology as well as the preparation method and the construction method of the self-healing seamless terrace material, the functional microcapsules are pre-buried in the cement matrix, so that automatic detection and self-healing of microcracks are realized, the terrace is upgraded from anti-cracking to active crack healing, and the service life of the terrace is fundamentally prolonged.
