High-performance building waterproofing agent

Abstract

The invention provides a high-performance building waterproofing agent which is characterized by comprising a component A and a component B, wherein the component A comprises the following ingredientsin parts by weight: 0.5-3 parts of expanded perlite, 5-10 parts of aluminum potassium sulfate, 3-9 parts of sodium silicate, 15-20 parts of magnesium stearate and 1-3 parts of a plasticizer; the component B comprises the following ingredients in parts by weight: 8-12 parts of methylcellulose, 0.3-0.8 parts of polyurethane foam materials, 15-20 parts of coal ash and 9-13 parts of triethanolamine;the high-performance building waterproofing agent is a powder-like waterproofing agent, and the weight ratio of the component A and the component B is 6-13 to 7. The waterproofing agent has the effects of water resistance and crack resistance, and the thermal insulation property of a wall body can be improved; the waterproofing agent is convenient in use, is non-toxic and environmentally friendlyand is applicable to dry and humid environments; the raw materials of the waterproofing agent are easily obtained.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-performance building waterproofing agent. Background technique [0002] The quality of waterproof engineering is directly related to the service life of buildings and structures and the people's living and working in peace and contentment. In recent years, the incidence of roof waterproof leakage in my country's buildings is extremely high, and some buildings leaked when they were not delivered. , At present, the leakage rate of the roof during the waterproof warranty period exceeds 50%. For the leakage of housing construction, it is usually the partial failure of the external defense of the building, resulting in leakage of the waterproof layer, and the seepage must pass through the defects of the concrete to enter the interior of the building. Water seepage is very common in parts with poor impermeability due to improper ramming. Most of the conven...

Problems solved by technology

In addition, the building waterproofing agents currently on the market often only have the function of waterproofing and anti-leakage, and have a single function. The waterproofing agents applied to concrete, mortar, building materials, etc. often have the function of crack resistance, and have no effect on the thermal insulation performance of the wall.
