Abstract

The invention discloses a preparation method of a waterproof material. The preparation method comprises the following steps: preparation of a material A: mixing citric acid, beryllium tartrate, tartaric acid, maleic acid, ammonium formate and calcium metaaluminate, drying, sieving, roasting and grinding to obtain the material A; preparation of a material B: mixing calcium carbonate, sodium carbonate, sodium silicate, sodium stearate, alumina, sodium citrate pentahydrate, sodium metatitantate, sodium phosphate hydrate, calcium formate and calcium metaaluminate, drying, sieving, roasting and grinding to obtain the material B; preparation of a material C: mixing kaolinite, sodium carbonate powder and a hydrochloric acid solution, successively carrying out first heating treatment and secondaryheating treatment, and grinding to obtain the material C; mixing the material A, the material B and the material C, roasting and carrying out secondary tempering treatment to obtain a building core material; mixing Portland cement, the building core material, sodium silicate and water so as to obtain the waterproof material. Many deficiencies in performance of traditional waterproof materials aresolved.

Description

Technical field [0001] The invention relates to the field of composite materials, in particular to a method for preparing waterproof materials. Background technique [0002] Waterproof material is the building envelope structure to prevent the penetration of rain, snow and ground water; to prevent the moisture, steam and other harmful gases and liquids in the air from corroding; the partition structure to prevent the seepage of water supply and drainage. These anti-seepage, leakage and erosion materials are collectively referred to. For example, the invention with the patent number CN201610041861.3 discloses an elastic cement-based permeable crystalline waterproof coating, which effectively solves the problem of easy cracking of the existing cement-based permeable crystalline waterproof coating, low impermeability pressure of the material, low compressive strength, and the base layer The problem of difficult adhesion and poor waterproof effect. The waterproof coating consists of...
