Flexible compound waterproof and leakage-plugging emulsion used for wall surface and roof

Abstract

The invention belongs to the technical field of waterproof and leakage-plugging supplies and relates to a flexible compound waterproof and leakage-plugging emulsion used for wall surfaces and roofs. 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, 30-34% of a polyethylene resin liquid, 45-50% of a vinyl acetate-ethene copolymerization emulsion, 4-6% of a methyl cellulose liquid, 3-5% of a water-soluble organosilicon, 11.98-15% of a polyvinyl alcohol rubber powder liquid and 0.01-0.03% of an antifoaming agent. Components of the dry powder compound sand material includes, by weight, 30-40% of portland cement, 30-35% 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 10-15% of dry lime. The emulsion is novel and scientific in formula, reasonable in component proportion, mature in preparation technology, good in bonding property, excellent in flexibility, good in waterproof performance and environment-friendly to use.

Description

Technical field: [0001] The invention belongs to the technical field of waterproof plugging products, and relates to a flexible composite waterproof plugging emulsion for walls and roofs, which is used for waterproof plugging of roofs, facade wall concrete and other projects. 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 in concrete houses, roofs, tunnels, subways, underground engineering, ditches, pond cracks, and uncompacted and empty parts of concrete. Waterproof treatment, using a variety of processes including high-pressure grouting ...

AI Technical Summary

Problems solved by technology

However, we know that various underground projects such as sewers, ditches, tunnels, and basements are quite different from above-ground projects such as houses, walls, and roofs. There are some differences, but there is no leak-stopping agent specially used in underground engineering or above-ground engineering in the prior art, so it is sought to design a composite plugging waterproof emulsion with good toughness and softness, which is specially used for repairing, Filling underground projects and walls, roofs, deformation joints, cracks, and seepage and leakage projects that are not compacted due to vibration
