Abstract

The invention relates to a method for preparing low-temperature-resisting waterproof mortar. The method comprises the following steps: heating fatty acid magnesium, adding polyimide grains, quartz sand and kieselguhr, unfiromly stirring, and cooling, thereby obtaining modified powder; adding a cationic surfactant and glycerol, heating and mixing in a mixing machine, and cooling to room temperature, thereby obtaining a cationic prefabricated body; heating and mixing polymethyl acrylate latex powder, an anionic surfactant, epoxy resin, o-hydroxybenzoic acid phenyl ester, inorganic fibers and ethyl acetate, and cooling, thereby obtaining an anionic prefabricated body; mixing the cationic prefabricated body and the anionic prefabricated body, drying and carrying out ball milling, thereby obtaining a mixture; and mixing the mixture with water, coal ash, gypsum and cement, thereby obtaining the waterproof mortar. As the inorganic fiber and the inorganic grains are respectively modified by using anions and cations, the inorganic fiber and the inorganic grains can be easily wrapped by each other, and the cold resistance of the mortar with the inorganic fiber and the inorganic grains is improved.

Description

technical field [0001] The invention relates to a preparation method of low-temperature-resistant waterproof mortar, which belongs to the technical field of building materials. Background technique [0002] Waterproof mortar has good weather resistance, durability, impermeability, compactness, high adhesion and strong waterproof and anti-corrosion effect. It can resist the corrosion of soda ash production medium, urea, ammonium nitrate, seawater hydrochloric acid and acid-base salt. It is mixed with ordinary sand cement and special cement to make cement mortar. By mixing the cement mortar, casting or spraying, and manually applying it, a strong waterproof and anti-corrosion mortar layer is formed on the concrete and the surface. It is a rigid, tough, waterproof and anti-corrosion material. Mixing with cement and sand can modify the mortar, which can be used for the treatment of building walls and ground and the waterproof layer of underground engineering. There are thre...
