Concrete anti-carbonization inhibitor and preparation method thereof
The invention discloses a concrete anti-carbonization inhibitor and a preparation method thereof, and relates to the technical field of concrete surface protection. The anti-carbonization inhibitor comprises a film-forming agent, a film-forming accelerant, a CO2 absorbent, a hole sealing agent and a penetrating agent; wherein the film forming agent is one or more of magnesium fluosilicate, sodium fluosilicate and gamma-(2, 3-epoxypropoxy) propyl trimethoxy silane; the film-forming accelerant is one or more of lithium silicate, sodium silicate and potassium silicate; the CO2 absorbent is one or more of potassium carbonate, sodium carbonate, triethanolamine and 2, 2-dihydroxydiethylamine; the hole sealing agent is modified silica sol; and the penetrating agent is one or more of hexadecyl trimethyl ammonium bromide, hexadecanol polyoxyethylene ether dimethyl octyl ammonium chloride and octadecyl dimethyl benzyl ammonium chloride. According to the concrete anti-carbonization inhibitor, the raw materials are easy to obtain, the preparation process is simple, CO2 can be physically isolated, CO2 diffused to the surface of concrete can be absorbed, and concrete carbonization inhibition dual protection is achieved.
本发明公开了一种混凝土防碳化抑制剂及其制备方法，涉及混凝土表面防护技术领域。所述防碳化抑制剂包括成膜剂、成膜促进剂、CO2吸收剂、封孔剂和渗透剂；其中成膜剂是氟硅酸镁、氟硅酸钠和γ‑(2,3‑环氧丙氧)丙基三甲氧基硅烷中的一种或几种；成膜促进剂是硅酸锂、硅酸钠及硅酸钾中的一种或几种；CO2吸收剂为碳酸钾、碳酸钠、三乙醇胺和2,2‑二羟基二乙胺中的一种或几种；封孔剂为改性硅溶胶；渗透剂为十六烷基三甲基溴化铵、十六醇聚氧乙烯醚二甲基辛烷基氯化铵和十八烷基二甲基苄基氯化铵中的一种或几种。本发明所述的混凝土防碳化抑制剂原料易得、制备工艺简单，既可以将CO2物理隔离，又可以吸收扩散至混凝土表面的CO2，实现了混凝土碳化抑制双重保护。
