Superstrong deeply capillary crystalline waterproof material

Abstract

The invention discloses a superstrong deeply capillary crystalline waterproof material and belongs to the technical field of waterproof materials. The superstrong deeply capillary crystalline waterproof material comprises the following components in percentage by weight: 42-50% of silicate cement, 1-5% of sodium methyl naphthalene sulphonate condensate, 7-10% of siloxane, 6-10% of calcium hydroxide, 10-15% of bentonite, 28-40% of quartz sand and 6-12% of aluminium potassium sulphate dodecahydrate. A preparation method of the superstrong deeply capillary crystalline waterproof material comprises the following steps: adding siloxane into bentonite, uniformly stirring, and then drying slurry; grinding the dried slurry into powder of 150-220 meshes generally in a ball grinding mill, then adding surface active dispersing agents, namely sodium methyl naphthalene sulphonate condensate and quartz sand, stirring for forming aggregates, and finally adding silicate cement, sodium silicate, aluminium potassium sulphate dodecahydrate and calcium hydroxide, so that the superstrong deeply capillary crystalline waterproof material finished product is obtained. The superstrong deeply capillary crystalline waterproof material can maintain respiratory action of a building, unique acicular crystals are generated and can fill and block cracks and holes of concrete, water seepage is prevented, waterproof effect is permanent, and no toxicity or pollution is produced.

Description

technical field [0001] The invention relates to a super deep penetration crystalline waterproof material, in particular to a super deep penetration crystalline waterproof material for underground buildings. Background technique [0002] At present, there are many waterproof materials on the market, which can be divided into two categories: flexible and rigid waterproof. Years of practice have proved that flexible waterproof materials such as coiled materials and coatings. Although it has the characteristics of being soft and attached to the surface of the building, it has poor adhesion to the wet concrete base. The main body of concrete is deformed and cracked. When loose, the flexible waterproof material loses its effect, and even becomes garbage that pollutes the groundwater and soil environment. The use of flexible waterproof materials in buildings with underground saline-alkali soil and coastal water quality not only rots quickly but does not have the effect of waterpr...

Problems solved by technology

[0003] In construction engineering, many buildings have waterproof and anti-seepage requirements. However, the anti-seepage and waterproof performance of ordinary concrete cement is poor, and water can penetrate through the micropores of concrete cement. Therefore, in general construction, the facing surface of ordinary concrete or Waterproof membranes, coatings and other materials are used on the back surface to isolate the water source. This construction process is more complicated, and the waterproof effect cannot be guaranteed; there is also a rigid inner waterproof structure, but its crack resistance is poor, and all voids and holes in the porous structure cannot be completely eliminated. For the healing of cracks, the waterproof effect is not good and the waterproof cost is high; there are also cement-based permeable crystalline waterproof coatings, which can not only ensure waterproof performance, but also reduce waterproof costs. However, most of them are mixed with water in use. Painted on the surface of concrete, it is difficult to fill the existing cracks on the concrete surface
