Anti-carbonization construction method for multiple coastal sluice projects, concrete anti-carbonization coating and preparation method of concrete anti-carbonization coating
The invention provides an anti-carbonization construction method for multiple coastal sluice projects, a concrete anti-carbonization coating and a preparation method of the concrete anti-carbonization coating, and belongs to the technical field of concrete protective materials. The concrete anti-carbonization coating is prepared from the following raw materials in parts by mass: 40 to 65 parts of polymer emulsion, 2 to 4 parts of a coalescing agent, 0.3 to 1 part of a dispersing agent, 1 to 1.5 parts of a carbonization inhibitor, 4 to 5 parts of gamma-glycidoxypropyltrimethoxysilane, 10 to 15 parts of ethanol and 20 to 35 parts of water, the carbonization inhibitor is formed by modifying sodium silicate with 3-mercaptopropyltrimethoxysilane sulfonic acid and then compounding the modified sodium silicate with poly (diallyldimethylammonium chloride); the structure of the carbonization inhibitor is in a core-shell shape, the core is sodium silicate, and the shell is poly dimethyl diallyl ammonium chloride. When the concrete anti-carbonization coating is applied to coastal sluice engineering, the anti-carbonization performance and the waterproof performance of engineering concrete buildings can be improved.
本发明提供一种多台风沿海水闸工程防碳化施工方法、一种混凝土防碳化涂料及其制备方法，属于混凝土防护材料技术领域。其中，一种混凝土防碳化涂料，以质量份数计，其原料组成包括：聚合物乳液40‑65份、成膜助剂2‑4份、分散剂0.3‑1份、碳化抑制剂1‑1.5份、γ‑缩水甘油氧基丙基三甲氧基硅烷4‑5份、乙醇10‑15份、水20‑35份；所述碳化抑制剂由3‑巯丙基三甲氧基硅烷磺酸改性硅酸钠后再与聚二甲基二烯丙基氯化铵复合构成；所述碳化抑制剂的结构为核壳状，核芯为硅酸钠，壳为聚二甲基二烯丙基氯化铵。将上述混凝土防碳化涂料应用于沿海水闸工程，可以提高工程混凝土建筑的抗碳化性能，以及防水性能。
