AI Technical Summary

Problems solved by technology

Some products solidify quickly but have poor adhesion, and their application is limited to water blocking; some products have high organic content and good adhesion, but the solidification time is long, and they must be used in a dry and ventilated place. It is used as a water blocking material and cannot be used in underground projects without ventilation due to the long construction period

Abstract

A water-proof leakage-blocking agent is prepared from water-hardening cement, polymer emulsoid powder, engineering cellulose, disperser, defoaming agent, bulking agent, water-reducing agent, and reinforcing filler through proportionally mixing and grinding. Its advantages are high effect and strength, integration of water proofing, leakage blocking and adhering, and not cracking.

Description

technical field [0001] The invention relates to an inorganic waterproofing agent for building, in particular to a single-component waterproofing and plugging agent which is formed by mixing hydraulic cement base material and other inorganic and organic substances. Background technique [0002] At present, the hydraulically rigid gelled waterproof materials produced at home and abroad are all based on cement and mixed with inorganic or organic additives. Some products solidify quickly but have poor adhesion, and their application is limited to water blocking; some products have high organic content and good adhesion, but the solidification time is long, and they must be used in a dry and ventilated place. It is used as a water blocking material and cannot be used in underground projects without ventilation due to the long construction period. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a single-c...
