Self-repairing concrete pipe and preparation method thereof
The invention relates to the technical field of building materials, and discloses a self-repairing type concrete pipe and a preparation method thereof.The self-repairing type concrete pipe comprises a microcapsule self-repairing material based on plant extracts, plant oil-based polyurethane is formed by reacting isocyanate with polyhydric alcohol; the microorganism self-repairing material comprises a bacillus microorganism capable of depositing calcium carbonate; according to the degradable polymer microcapsule, a degradable polymer is polylactic acid and can be naturally degraded in the environment; the cement-based material comprises Portland cement, a fine aggregate and a coarse aggregate. By integrating the plant extract microcapsule, the microbial self-repairing material and the degradable polymer microcapsule, the problems that the cracks of the concrete pipeline are difficult to automatically repair, the performance is reduced and the maintenance cost is high are solved, automatic crack repairing is realized, the permeability resistance is enhanced, the service life of the pipeline is prolonged, and environmental protection and high efficiency are realized.
本发明涉及建筑材料技术领域，公开了自修复型混凝土管及其制备方法，包括：基于植物提取物的微胶囊自修复材料，所述植物油基聚氨酯通过异氰酸酯与多元醇反应形成；微生物自修复材料，所述微生物自修复材料包括能够沉积碳酸钙的芽孢杆菌属微生物；可降解聚合物微胶囊，所述可降解聚合物为聚乳酸，可在环境中自然降解；水泥基材料，所述水泥基材料包括硅酸盐水泥、细集料和粗集料。通过集成植物提取物微胶囊、微生物自修复材料和可降解聚合物微胶囊，本发明解决了混凝土管道裂缝难以自动修复、性能下降和维护成本高的问题，实现了自动修复裂缝、增强抗渗透性，并延长了管道使用寿命，且环保高效。
