Description

Water-based sound-insulation modified polymer cement-based waterproof slurry and preparation method thereof
Technical Field

Background
Along with the improvement of requirements of people on the quality of building engineering and the use function of buildings, the problems of wall body waterproofing, damp interface waterproofing and basement waterproofing are more and more concerned and valued in the building industry. In the traditional waterproof concept, flexible waterproof materials such as coiled materials, sheets and coatings are often used as independent waterproof materials in engineering. The flexible waterproof materials have strong basic layer deformation capability and convenient large-area construction, but the flexible waterproof materials have higher requirements on the basic layer drying degree, generally require the water content to be below 9 percent, and are difficult to achieve for underground engineering (particularly deep basements) and poorly ventilated washrooms. And when the bathroom facade uses coiled materials or sheets, the general facing bricks are difficult to be directly bonded on the waterproof layer.
In recent years, large-scale development and application of urban underground space are realized, a large number of underground civil air defense projects are repaired and recycled, the waterproof of the occasions is based on the principle of rigid-flexible combination and multi-defense, but many manufacturers expand the application range of rigid waterproof materials (such as water-tight cement-based permeable crystallization type waterproof materials and the like) on one side and are applied to waterproof construction of the back surface and the upstream surface of the underground project. The practical application of engineering finds that the rigid waterproof material has the biggest defects of no flexibility, poor crack resistance, easy cracking when the wall has micro cracks or vibration caused by beating in decoration, and poor impermeability. The widely adopted method for blocking the capillary pores of the concrete by the waterproof agent plays a certain role in reducing the defects of the concrete and the cement mortar. However, the internal structure form of the material is not changed, so that the waterproof effect is not ideal, particularly, the waterproof effect cannot meet the requirement of building waterproofing as an independent waterproof layer, and the common waterproof slurry has no sound insulation effect.
