Concrete surface anti-carbonization coating and preparation process thereof
The present invention relates to a concrete surface anti-carbonization coating, which comprises a primer, a middle layer paint and a finishing paint, and the primer comprises 1-6 parts of a polycarboxylic acid super plasticizer. According to the concrete surface anti-carbonization coating and the preparation process thereof, after the concrete surface anti-carbonization coating is applied, a polymer-cement hydration product intertransmission network structure is formed on the concrete surface, and chemical and mechanical combined cohesive force and adhesive force are generated; a high-strength, tough and durable elastic coating film protection layer which is firmly combined with the concrete surface is formed on the concrete surface, so that the erosion of harmful media such as carbon dioxide, sulfide, acid rain and chloride ions in the environment on the concrete structure can be effectively prevented; the advantages that inorganic materials are easy to obtain, good in durability (the service life is generally longer than that of silane and epoxy similar products), environment-friendly and low in price (the cost is generally only higher than that of the silane and epoxy similar products) are reserved, and the advantage of high flexibility of high polymer materials is exerted.
本发明涉及一种混凝土表面防碳化涂料，包括底漆、中层漆和面漆，所述底漆包括聚羧酸类超塑化剂1‑6份。该混凝土表面防碳化涂料及其制作工艺，混凝土防碳化涂料涂施后，在混凝土表面形成聚合物——水泥水化产物的互传网络结构，产生化学与机械结合的内聚力与附着力，在混凝土表面形成一层与其牢固结合的高强坚韧耐久的弹性涂膜保护层，可有效阻止环境中二氧化碳、硫化物、酸雨、氯离子等有害介质对混凝土结构的侵蚀，并且既保留了无机材料易得、耐久性好(通常比硅烷和环氧类同类产品寿命长年)、环境友好，价格便宜(通常只有硅烷和环氧类同类产品造价的)的优点，又发挥了高分子材料高柔韧性的优势。
