Cement-based capillary crystalline building waterproof material and preparation method thereof

Abstract

The invention relates to the technical field of waterproof material processing, and discloses a cement-based capillary crystalline building waterproof material. The building waterproof material is characterized by comprising the following raw materials in parts by weight: 100 parts of sulphoaluminate cement, 7-15 parts of a capillary crystalline active master batch, 65-100 parts of quartz sand, 3-6 parts of aluminum potassium sulfate, 1-10 parts of calcium carbonate, 10-15 parts of talcum powder, 0.1-0.2 parts of cellulose, 6-12 parts of rubber powder, 0.55-1.2 parts of a water reducing agent,4.2-6.2 parts of other additives and 110 parts of tap water. According to the cement-based capillary crystalline building waterproof material and the preparation method thereof, the deep crystallinewaterproof material has anti-seepage, anti-corrosion, anti-freezing, anti-cracking, anti-alkali and anti-aging properties, the product is non-toxic, tasteless and non-radioactive, has a very good protection effect on concrete and is excellent in cost performance and safe to people and livestock, the problem that the conventional pure cement type waterproof material is easy to crack and poor in impermeability and waterproof effects is solved, the material has certain high and low temperature resistance, and the early strength of the material is improved.

Description

Technical field [0001] The invention relates to the technical field of waterproof material processing, in particular to a cement-based permeable crystalline building waterproof material and a preparation method. Background technique [0002] With the rapid economic development, the declining land resources, and the continuous improvement of living conditions, the high-rise and high-quality buildings are an inevitable trend; on the other hand, subway and tunnel projects are increasing, and many second-tier cities have also built subways. Therefore, the quality of building waterproof materials plays a vital role in the quality of these construction projects. It is related to the use value, use conditions and sanitary conditions of the building, and affects people's production activities, work and life quality . [0003] Building waterproof materials are divided into rigid waterproofing and flexible waterproofing according to the principle and appearance. Rigid waterproofing mainly ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cement-based permeable crystalline building waterproof material and a preparation method, which has the advantage of strong crack resistance, and solves the problem of high brittleness of the waterproof material, and flexible waterproof materials are used for flexible waterproofing. The durability of this kind of flexible waterproof is poor, and it is easy to peel off from the base surface to produce two layers of skin.
