Capillary crystallization type self-healing waterproof material for self-waterproofing of concrete
The invention relates to the technical field of building materials, and provides a permeable crystallization type self-healing waterproof material for concrete self-waterproofing, which is prepared from the following raw materials in parts by weight: 20 to 30 parts of sodium bentonite, 20 to 50 parts of sodium methyl silicate, 4 to 6 parts of penetrant, 8 to 12 parts of sulphoaluminate cement, 15 to 18 parts of silicone zirconium and 2 to 5 parts of complexing agent. The complexing agent is prepared from 2-[3-(4-pentylphenyl) propan-2-alkenyl amide] benzoic acid and sodium ethylene diamine tetracetate. According to the technical scheme, the problem that in the prior art, concrete is low in mechanical property and water resistance is solved.
本发明涉及建筑材料技术领域，提出了一种用于混凝土自防水的渗透结晶型自愈合防水材料，包括以下重量份组分的原料：20~30份钠基膨润土、20~50份甲基硅酸钠、4~6份渗透剂、8~12份硫铝酸盐水泥、15~18份硅酮锆、2~5份络合剂；所述络合剂由2‑[3‑(4‑戊基苯基)丙‑2‑烯酰氨基]苯甲酸和乙二胺四乙酸钠组成。通过上述技术方案，解决了现有技术中混凝土力学性能和防水性较低的问题。
