Temperature-inhibiting type self-healing concrete anti-cracking waterproof agent and preparation method thereof
The invention relates to the technical field of building materials, and particularly provides a temperature-inhibiting type self-healing concrete anti-crack waterproof agent and a preparation method thereof.The temperature-inhibiting type self-healing concrete anti-crack waterproof agent is prepared from, by weight, 10-30 parts of modified nano-silicon dioxide, 15-25 parts of modified maltodextrin, 5-10 parts of sodium metasilicate, 4-8 parts of sodium gluconate and 3-6 parts of modified 3-mercaptoalanine. 3-5 parts of calcium nitrate, 2-4 parts of potassium hydroxide, 1-2 parts of a defoaming agent, 1-2 parts of a dispersing agent and 30-50 parts of water. The anti-crack waterproof agent disclosed by the invention has self-healing capability, can effectively inhibit hydration heat and reduce the hydration heat release rate of concrete so as to prevent the generation of temperature cracks, can effectively improve the durability, workability and waterproofness of a concrete structure, and has a relatively good market prospect.
本发明涉及建筑材料技术领域，具体提供了一种抑温型自愈合混凝土抗裂防水剂及其制备方法，按重量份计，所述抗裂防水剂包含以下原料：改性纳米二氧化硅10‑30份，改性麦芽糊精15‑25份，偏硅酸钠5‑10份，葡萄糖酸钠4‑8份，改性3‑巯基丙氨酸3‑6份，硝酸钙3‑5份，氢氧化钾2‑4份，消泡剂1‑2份，分散剂1‑2份，水30‑50份。本发明的抗裂防水剂具有自愈合能力，能有效抑制水化热，降低混凝土水化放热速率，进而防止温度裂缝的产生，同时其能够有效提高混凝土结构的耐久性、和易性和防水性，具有较好的市场前景。
