Abstract

The invention discloses a method for preparing concrete waterproof material, and the preparation method comprises: mixing cesium stearate, cesium chloride, sodium citrate, calcium carbonate, sodium carbonate, sodium silicate, beryllium carbonate, sodium hydrogen carbonate, calcium metaaluminate and calcium chloride, drying, sieving, roasting and grinding to obtain material A; mixing D-malic acid,L-malic acid, cesium tartrate, tartaric acid, sodium malate and calcium metaaluminate, drying, sieving, roasting and grinding to obtain material B; mixing gedanite, cesium carbonate and hydrochloric acid solution, performing heating treatment, and grinding to obtain material C; mixing the material A, the material B and the material C, roasting and carrying out secondary tempering treatment to obtain a crystalline composite material; mixing the silicate cement, the crystalline composite material, the sodium silicate, the quartz sand and the water to obtain a concrete waterproof material. The concrete waterproof material solves the problems that the traditional concrete waterproof material has insufficient impermeability and compressive strength, and bad waterproof effect.

Description

technical field [0001] The invention relates to the preparation of waterproof materials, in particular to a preparation method of concrete waterproof materials. Background technique [0002] The waterproof material is the building envelope to prevent the penetration of rainwater, snow water and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air; the separation structure to prevent the seepage of water supply and drainage. These materials that prevent penetration, leakage and erosion are collectively referred to. For example, the Chinese invention with the patent number CN2017103788000 provides a graphene self-crystallization waterproof active masterbatch and its preparation method. Based on the total mass, the mass percentage of each component is: including 1-15wt% of graphene, 55-75wt% of calcium compensator, 5-20wt% of penetrating crystallization agent, and 2-10wt% of chelating agent. First add graphene into water, ultra...
