The invention relates to the field of concrete protection, and particularly discloses a concrete salt-resistant protective agent. The concrete salt-resistant protective agent comprises a component A and a component B. The component A comprises 1-10 parts of alkyl siloxane, 10-20 parts of sodium alginate, 3-4 parts of calcium gluconate and 2.1-2.9 parts of dispersing agent, the component A is coated to form microcapsule particles with the average particle size of 50 nm, and the component B comprises 0.01-0.1 part of silicone acrylic emulsion. The component A and the component B are separately stored, added into distilled water for blending during use and compounded into the concrete salt-resistant protective agent. As the component A microcapsules can quickly permeate into concrete along with water and are slowly released in the concrete, the time for condensation of silicon hydroxyl of alkyl siloxane and hydroxyl existing in the concrete to form an organic silicon network is prolonged,the permeability of the concrete salt-resistant protective agent is improved, the permeation depth of the concrete salt-resistant protective agent is high, and thus the formed hydrophobic membrane isrelatively deep in position and has relatively good waterproof and salt-resistant properties.
本申请涉及混凝土防护领域，具体公开了一种混凝土抗盐保护剂。一种混凝土抗盐保护剂包括A组分和B组分，其中A组分包括烷基硅氧烷1‑10份、海藻酸钠10‑20份、葡萄糖酸钙3‑4份和分散剂2.1‑2.9份，A组分经过包覆制成平均粒径为50nm的微胶囊颗粒状，B组分包括0.01‑0.1份的硅丙乳液；A组分和B组分分开存放，在使用时加入至蒸馏水中共混，复配成混凝土抗盐保护剂。由于A组分微胶囊能随水快速渗入混凝土内部，且在混凝土内部缓释，延长烷基硅氧烷的硅羟基与混凝土内部存在的羟基进行缩合形成有机硅网络的时间，增大混凝土抗盐保护剂的渗透性，并且由于混凝土抗盐保护剂的渗透深度较大，其形成的疏水膜的位置较深，起到较好的防水抗盐性。
