Abstract

The invention provides a bentonite anti-seep jointing material which mainly comprises adhesive, swelling agent, buckling modifier, adjuvant and thinning agent, the contents of the constituents are adhesive 20-45 wt%, plumping agent 25-50%, buckling modifier 0.5-2%, adjuvant 0.5-20%, thinning agent 5-15%.

Description

technical field [0001] The invention belongs to civil engineering construction materials, and relates to waterproof materials, in particular to bentonite anti-leakage caulking materials. Background technique [0002] Bentonite has a high degree of water tightness and self-repairing and restoration functions, and is theoretically the closest to a perfect waterproof material. Therefore, it has been widely used in various civil engineering projects, not only for underground diaphragm wall construction, caissons, caissons, pipe jacking, pile jacking, underground waterproofing, concrete plasticizing additives, but also for tunnel protection, sewage treatment And wire ground cover soil and so on. The most significant increase in recent years is mainly soil sealing, underground diaphragm wall construction and waterproof mortar. Bentonite can effectively adsorb pollutants, and can be used as soil filler for anti-seepage of waste landfills, pools, ditches, reservoirs and canals. I...
