Problems solved by technology

However, domestic osmotic crystalline waterproof materials are mainly configured by importing osmotic crystalline masterbatches, such as Chinese patent numbers CN102786275B, CN101362867A, CN101654351A, etc. Therefore, the production cost of waterproof materials is relatively high, which limits its application in concrete waterproofing projects.

Abstract

The invention discloses an inorganic silicon-organic silicon composite infiltration crystalline type concrete waterproofer which is prepared from, by weight, 10-18 parts of sodium silicate, 3-8 parts of methanesiliconic acid sodium salt, 2-7 parts of sodium alga acid, 8-10 parts of gelatin, 1-4 parts of dodecyl ethoxy sulfo betaine, 2-4 parts of sodium carbonate, 1-4 parts of sodium citrate, 2-5 parts of triethanolamine, 2-9 parts of aluminium potassium sulfate, 3-6 parts of calcium sulfate, 1-3 parts of sodium polyacrylate, 1-5 parts of calcium lignosulphonate, 1-3 parts of carboxymethylcellulose, 2-5 parts of calcium chloride, 1-3 parts of boric acid and 60-90 parts of water. The inorganic silicon-organic silicon composite infiltration crystalline type concrete waterproofer has good waterproof performance, endurance quality and self healing performance, is low in cost and can be applied to watertightness of roofs, basements, toilets and the like.

Description

technical field [0001] The invention relates to an inorganic silicon-organic silicon composite permeable crystalline concrete waterproofing agent, which belongs to the technical field of concrete building waterproofing materials. Background technique [0002] Concrete is a multi-phase composite brittle material, its tensile strength is relatively low (about 1 / 20-1 / 10 of the compressive strength), and the ultimate tensile strain is relatively small (only 0.02%-0.03%). When it is in the process of hydration and hardening, due to drying shrinkage, chemical shrinkage, carbonation shrinkage and other reasons, the internal tensile stress caused by volume shrinkage and deformation is greater than its own tensile strength, cracking will occur in concrete, which can not only destroy its The impermeability of the structure will also affect its durability, the stability of steel bars and the safety of the building. In addition, concrete is also a heterogeneous material. From the persp...
