Problems solved by technology

However, this technology also has obvious disadvantages: (1) The method of grouting is helpless for the infiltration of the concrete surface caused by the inaccurate vibration of concrete, because no obvious cracks can be found during the grouting process, so the passage of grouting cannot be formed; (2) For cracks after grouting, if the cracks continue to expand due to factors such as foundation settlement, it may cause the second leakage

Abstract

The invention relates to the technical field of plugging agents, in particular to a plugging agent special for a building roof crack. The plugging agent comprises, by weight, the raw materials of 30-50 parts of silicone rubber, 20-30 parts of calcium sulphoaluminate, 10-20 parts of sepiolite, 5-10 parts of Teflon, 8-16 parts of sodium tripolyphosphate, 8-18 parts of titanium dioxide, 5-10 parts of wollastonite and 10-20 parts of curing agent. The plugging agent special for the building roof crack can both be used on the upstream face and the downstream face, impermeability pressure is high, cementation power is high, anti-cracking effect is good, the plugging agent and a base body are combined into a whole, ultraviolet resistance and aging resistance are achieved, waterproof performance is obvious, and waterproof performance, permeability resistance and quick plugging are achieved.

Description

technical field [0001] The invention relates to the technical field of leak-stopping agents, in particular to a special leak-stopping agent for building roof cracks. 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%. [0003] 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 ...
