Waterproof adhesive material for cement-based rigid interface

Abstract

The invention discloses a waterproof adhesive material for a cement-based rigid interface. The waterproof adhesive material is prepared from the following substances in parts by weight: 40-60 parts of cement, 30-50 parts of mineral filler, 0-5 parts of water retention agent, 0-3 parts of defoamer, 0-5 parts of efflorescence resisting agent, 0-1 part of mildew and alga preventing agent, 0-3 parts of efficient water reducing agent, 0-3 parts of re-dispersible latex powder and 20-30 parts of water. The waterproof adhesive material for the cement-based rigid interface has the advantages that the waterproof adhesive material is easily brushed on different surfaces and has a good adhesive property with base layers; and the efflorescence resisting agent is added, so that the corrosion to the base layers caused by chloride ions can be reduced, the density of the base layers is increased, and then, the chemical corrosion resistance and durability of the material are improved.

Description

technical field [0001] The invention relates to a cement-based rigid interface waterproof bonding material. It can be used for waterproofing of internal and external walls, roofs, kitchens, toilets and underground works of buildings. Background technique [0002] The application of waterproof materials in construction engineering has a long history. In order to avoid the impact of rainwater penetration and moisture on buildings in humid climates, polymers are usually directly painted on the base of the building, that is, the cement mortar plastering and leveling layer. Cement waterproof coating layer to avoid the impact of rainwater penetration and moisture on the building in humid climates. [0003] Because the mortar inside the base of the building is not firm and easy to loosen, when the polymer cement waterproof coating layer is painted on the base, the base of the building will be deformed by thermal expansion and contraction under the influence of external temperature...

AI Technical Summary

Problems solved by technology

[0003] Because the mortar inside the base of the building is not firm and easy to loosen, when the polymer cement waterproof coating layer is painted on the base, the base of the building will be deformed by thermal expansion and contraction under the influence of external temperature changes, which is not firm and easy to loosen. Loose mortar will cause displacement, resulting in the coating layer, hollowing or falling off, which will affect the safety of the building; and because the surface of the original building base is relatively rough, it is impossible to effectively apply the polymer cement waterproof coating on the base. On the surface, the amount of waterproof coating is larger and the cost is higher
