Self-flowing type high-strength early-strength self-compacting and self-repairing material and preparation method thereof
The invention discloses a self-flowing type high-strength early-strength self-compacting and self-repairing material and a preparation method thereof, relates to the field of material science, and solves the problems of contradiction between self-flowing property and early-strength property, limitation of self-compacting property, imbalance of self-repairing capability, high cost and the like. Firstly, preparation raw materials and a reaction device of the self-flowing type high-strength early-strength self-compacting and self-repairing material are prepared, the surface of the nanoscale silica fume is provided with a functional group carboxyl through surface modification, then biopolymer fibrin is fixed to the surface of the nanoscale silica fume, a photosensitizer 2-isopropyl thioxanthone continues to be added, and the self-flowing type high-strength early-strength self-compacting and self-repairing material is obtained. The preparation method comprises the following steps: adding a biopolymer fibrous protein into a biopolymer fibrous protein solution, carrying out self-assembly on the biopolymer fibrous protein solution to promote the biopolymer fibrous protein to simulate a blood coagulation mechanism of an organism, and finally uniformly mixing other preparation raw materials according to a preset ratio to obtain the self-flowing type high-strength early-strength self-compacting and self-repairing material. Meanwhile, the pollution in the production process is also reduced.
本发明公开了一种自流型高强早强自密实自修补型材料及制备方法，涉及材料科学领域，解决的问题是：自流性与早强性的矛盾、自密实性的局限性、自修补能力的不均衡和成本高等，首先准备所述自流型高强早强自密实自修补型材料的制备原料和反应装置，通过表面修饰，使所述纳米级硅灰的表面带有功能基团羧基，再将生物高分子纤维蛋白固定在所述纳米级硅灰表面，继续添加光敏剂2‑异丙基硫杂蒽酮，促使所述生物高分子纤维蛋白模拟生物体的凝血机制，进行自我组装，最后将其余制备原料按照预设比例混合均匀得到所述自流型高强早强自密实自修补型材料，本发明能够提高制备方法的生产效率和产品质量，同时也减少了生产过程中的污染。
