Preparation method of concrete self-repairing anti-crack corrosion-resistant rust-resistant waterproof material
The invention relates to the technical field of concrete waterproofing, and particularly discloses a preparation method of a concrete self-repairing anti-crack anti-corrosion anti-rust waterproof material, which comprises the following steps: S1, uniformly mixing calcium salt, ferric salt, aluminum salt and a hybrid solution to prepare a precursor solution; the hybrid liquid is prepared by adopting a method comprising the following steps: 1) uniformly mixing alkyl quaternary ammonium salt, phenethyl alcohol and deionized water to prepare an intermediate liquid; (2) adding carbomer into the intermediate solution in batches, and stirring until the intermediate solution is viscous; s2, adding water, silicate, silica sol, triethanolamine, fly ash, 2, 7-diaminofluorene, tetrabutyl phosphorus hydroxide, 1-hydroxyethylidene-1, 1-diphosphonic acid, L-cysteine and a dispersing agent into a stirring kettle in parts by weight, and uniformly mixing to obtain slurry; and S3, slowly adding the precursor solution into the slurry, and stirring for 1-2 hours. The concrete self-repairing anti-crack corrosion-resistant rust-resistant waterproof material has good self-repairing, waterproof and corrosion medium permeation hindering effects.
本申请涉及混凝土防水技术领域，具体公开了一种混凝土自修复抗裂防腐阻锈防水材料的制备方法，包括如下步骤：S1：取钙盐、铁盐、铝盐、杂化液混合均匀制得前驱液；所述杂化液采用包括如下步骤的方法制得：1）将烷基季铵盐、苯乙醇、去离子水混合均匀制得中间液；2）向中间液中分次加入卡波姆，搅拌至粘稠状即得；S2：按重量份计，取水、硅酸盐、硅溶胶、三乙醇胺、粉煤灰、2,7‑二氨基芴、四丁基氢氧化磷、羟基乙叉二膦酸、L‑半胱氨酸、分散剂加入搅拌釜内混合均匀制得料浆；S3：将前驱液缓慢加入料浆内，搅拌1‑2h后即可。本申请的混凝土自修复抗裂防腐阻锈防水材料具有较好自修复、防水、阻碍腐蚀介质渗透的效果。
