The invention relates to the field of concrete protection, and particularly discloses aconcrete freeze-thaw-resistant composite protective agent and a preparation method of the freeze-thaw-resistant composite protective agent. The concrete freeze-thaw-resistant composite protective agent is prepared from the following raw materials: silica sol, alkyl siloxane, a silane coupling agent, n-octylamine, a nonionic emulsifier and a microbial self-repairing agent. The preparation method comprises the following steps: preparing raw materials in proportion, and uniformly mixing the silica sol, the alkyl siloxane and the nonionic emulsifier to obtain a primary mixed solution; adding the silane coupling agent into the primary mixed solution, uniformly stirring, dropwise adding the catalyst n-octylamine, and continuously stirring until transparent and stable sol is obtained; adding water into the sol in a stirring state, and stirring to obtain an emulsion mixed solution; and mixing the mixed solution with the microbial self-repairing agent, and uniformly stirring to obtain the freeze-thaw-resistant composite protective agent. The composition can be used for freeze-thaw resistance protection ofconcrete, and has the advantages of improving the freeze-thaw resistance of the concrete and repairing the column fraction of the concrete.
本申请涉及混凝土防护的领域，具体公开了一种混凝土抗冻融复合防护剂及其制备方法。一种混凝土抗冻融复合防护剂，由以下原料制成：硅溶胶、烷基硅氧烷、硅烷偶联剂、正辛胺、非离子型乳化剂、微生物自修复剂；其制备方法为：按配比准备原料，将硅溶胶、烷基硅氧烷、非离子型乳化剂混合均匀，得到初混液；向初混液中加入硅烷偶联剂，搅拌至均匀后，滴加催化剂正辛胺，继续搅拌直至得到透明稳定的溶胶；在搅拌状态下向溶胶中加水，搅拌得到乳液状的混合液；将混合液与微生物自修复剂混合，搅拌均匀，得到抗冻融复合防护剂。本申请的产品该组合物可用于混凝土抗冻融防护，其具有提升混凝土抗冻融性能同时修复混凝土列分的优点。
