Problems solved by technology

The plugging material has the advantages of long mixing time, suitable for large-volume construction, and good volume stability. However, it is inconvenient for emergency construction, and the construction effect is not ideal when blocking open water.
[0005] In summary, the prior art still lacks an inorganic waterproof plugging material that can overcome the influence of temperature and quickly plug leaks.

Embodiment 1

[0045] (1) Accurately weigh 64kg of low-alkalinity sulfoaluminate cement with a strength of 43Mpa, 25.3kg of quartz sand with a mesh number of 1000, 10kg of composite early-strength agent, 0.5kg of latex powder, 0.2kg of cellulose, and 10kg of composite early-strength agent 4kg of Li in 2 CO 3 , 3kg of Al 2 (SO 4 ) 3 and 3kg of CaO;

[0046] (2) Add each component in the stirring tank, turn on the mixer, the stirring speed is 800 rpm, and stir for 3 minutes;

[0047] (5) Take a sample to test the coagulation time. If the coagulation time is less than 30s, the finished product can be obtained if the test is qualified.

Abstract

The invention discloses a quick-hardening inorganic waterproof plugging material, which is prepared from the following components in percentage by weight: 50-70% of an inorganic cementing material, 30-40% of a filler, 3-12% of a composite early strength agent, 0.3-0.8% of latex powder and 0.1-0.3% of cellulose. By adopting the composite early strength agent, the influence of air temperature on thesetting time can be effectively reduced, open water below 5m can be blocked, the waterproof and leaking stoppage effects are good, hardening can be realized within 30 seconds, the rapid leaking stoppage effect is achieved, high strength can be achieved within one hour, and the emergency construction requirement is met.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fast-hardening inorganic waterproof plugging material. Background technique [0002] The state of the base layer before the construction of the waterproof coating will directly affect the effect of the waterproof construction. The base layer is loose, cracked, sanded, and the water absorption rate is too high, which will cause the waterproof coating to bulge, crack, pinhole, peeling, etc. These phenomena will greatly reduce the performance of the waterproof coating. The overall waterproof effect. Inorganic waterproof plugging material is made of inorganic cementitious materials, sand, stone, and polymer additives. It has excellent properties such as short setting time, high early strength, continuous increase in later strength, and strong impermeability. It is suitable for most construction projects. Emergency waterproof and plugging treatment. [0003] CN107555917A disclose...
