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.

Embodiment Construction

[0027] Below in conjunction with embodiment, the present invention will be further described:

[0028] The osmotic crystalline concrete waterproofing agent of the present invention is made of the following components by weight: 15-25 parts of sodium silicate, 3-6 parts of sodium methyl silicate, 1-5 parts of sodium alginate 4-8 parts of gelatin, 1-5 parts of dodecyl ethoxy sulfobetaine, 1-3 parts of sodium carbonate, 1-4 parts of sodium citrate, 1-4 parts of triethanolamine, 2 parts of potassium aluminum sulfate ~10 parts, calcium sulfate 2~6 parts, polyacrylamide 1~3 parts, calcium lignosulfonate 1~6 parts, carboxymethyl cellulose 3~6 parts, calcium hydroxide 2~5 parts, boric acid 1~ 3 parts, 60-90 parts of water. In specific implementation, it can be directly applied to the base surface to be waterproofed by spraying or brushing, and repeated brushing to a certain thickness, and curing for 3 days or more is enough.

[0029] Table 1 shows the weight ratio of each component ...

Abstract

The invention discloses a permeable crystallization type concrete waterproofing agent, which is prepared from the following components by weight: 15-25 parts of sodium silicate, 3-6 parts of sodium methyl silicate, 1-5 parts of sodium alginate, 4-8 parts of gelatin, 1-5 parts of dodecyl ethoxy sulphobetaine, 1-3 parts of sodium carbonate, 1-4 parts of sodium citrate, 1-4 parts of triethanolamine, 2-10 parts of aluminum potassium sulfate, 2-6 parts of calcium sulfate, 1-3 parts of polyacrylamide, 1-6 parts of calcium lignosulphonate, 3-6 parts of carboxymethylcellulose, 2-5 parts of calcium hydroxide, 1-3 parts of boric acid, and 60-90 parts of water. The waterproofing agent disclosed by the invention has the advantages of good waterproof performance, durability and self-healing property, and low cost, and can be applied to waterproofing of roofing, basements, toilets and the like.

Description

technical field [0001] The invention relates to a 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 perspective of macrostructure, concrete is compose...
