Problems solved by technology

In this way, neither rigid waterproofing nor flexible waterproofing can be combined with the base of the building as a unified whole.
Therefore, it is easy to appear delamination, cracking, aging, falling off, etc., which seriously affects the quality and effect of waterproofing, and cannot really play a waterproof and anti-corrosion performance on buildings, thereby reducing the service life of buildings.

Abstract

The invention relates to a preparation method of a building composite waterproof material, and belongs to the technical field of building materials. According to the method, a styrene-acrylic emulsionis added to form the building composite waterproof material. The styrene-acrylic emulsion is an acrylate copolymer emulsion modified by styrene. The styrene is adopted to completely or partially replace methyl methacrylate in the emulsion, and styrene chain segments are introduced, so that the water resistance, the alkali resistance, the pollution resistance and the pulverization resistance of acoating film are improved, the durability of the material can be improved when the styrene is applied to the building waterproof material, and the bonding strength of the styrene to a building base material is high.

Description

technical field [0001] The invention relates to a preparation method of a building composite waterproof material, which belongs to the technical field of building materials. Background technique [0002] Building materials refer to the general term for various materials used in the field of construction and civil engineering, referred to as "building materials". Building materials in a narrow sense refer to materials used in civil engineering, such as steel, wood, glass, cement, paint, etc. Cement, steel and wood are usually called the three major materials of general construction engineering. Building materials in a broad sense also include materials used in construction equipment, such as wires and water pipes. "Building materials" in the discipline of architecture refers to the discipline that studies the physical and chemical properties of different building materials. [0003] Waterproof material is the enclosure structure of the building to prevent the penetration of...
