Rigid-flexible composite waterproof plugging emulsion for underground facilities

Abstract

The invention belongs to the technical field of waterproof and leakage-plugging construction and relates to a rigid-flexible composite waterproof and leakage-plugging emulsion for underground facilities. The emulsion includes two components comprising a compound adhesive waterproof emulsion and a dry powder compound sand material with a weight ratio being 1:1. Components of the compound adhesive waterproof emulsion include, by weight, 40-60% of a polyethylene resin liquid, 20-40% of a vinyl acetate-ethene copolymerization emulsion, 2-4% of a methyl cellulose liquid, 3-5% of a water-soluble organosilicon, 11-14% of a polyvinyl alcohol rubber powder liquid and 0.01-0.03% of an antifoaming agent. Components of the dry powder compound sand material include, by weight, 30-40% of Portland cement, 35-40% of quartz sand, 4-6% of a dispersible rubber powder, 3-5% of a polyvinyl alcohol dry rubber powder, 0.5-2% of propyl cellulose, 5-7% of a capillary crystalline active master batch, 4-6% of fly ash and 4-7% of dry lime. The emulsion is novel and scientific in formula, reasonable in component proportion, mature in preparation technology, good in adhesive property, strong in rigidity and hardness, good in waterproof performance and environment-friendly to use.

Description

Technical field:

[0001] The invention belongs to the technical field of waterproof plugging construction, and relates to a rigid-flexible composite waterproof plugging emulsion with high density and high strength, which is used for repairing and plugging various underground projects such as tunnels, basements, sewers, mines and dams. Leakage, in order to achieve a good waterproof seal plugging. Background technique:

[0002] In simple terms, waterproof plugging is the indoor and outdoor waterproofing construction of buildings and the repairing construction of indoor and outdoor leakage areas. Specifically, it is used professionally for water leakage in houses, tunnels, dams, medium leakage in pipeline containers, and damage and leakage of underground well pipes. Plugging tools and materials are used for repairing and filling to stop leakage. Waterproof plugging is mainly used for waterproofing of tunnels, subways, underground garages, underground engineering, ditches, ponds,...
