The invention has the flameproof function, and has the advantages of light weight, high strength, heat insulation, water resistance and moisture resistance, convenience for building construction and the like.

Description

technical field

[0001] The invention belongs to the technical field of new wall materials, and relates to an external thermal insulation board for an external wall made of cement and polystyrene particles as main raw materials and having a fireproof function. Background technique

[0002] The external thermal insulation board of the external wall is a building component used on the external surface of the external wall to provide thermal insulation for the building. For a long time, the thermal insulation material of the external wall insulation board has mostly used foamed plastic boards with low thermal conductivity such as polystyrene foam board (EPS) or polystyrene extruded board (XPS). Foamed plastics are flammable materials. If there is a fire in the building, the foam plastic insulation material of the external wall insulation board will be softened by high temperature, causing it to fall off. In severe cases, it will also support combustion. The poisonous gas release...

Embodiment 1

[0026] After mixing fast-hardening sulfoaluminate cement, polyphenylene particles, vitrified microbeads, sawdust, and naphthalene-based water reducer, add water and VAE emulsion to stir to form a slurry, inject it into a molding mold, and release the slurry after hardening to form Insulation layer for exterior insulation boards. After mixing the rapid-hardening sulfoaluminate cement, quartz sand and glass fiber, add water, polycarboxylate superplasticizer, and VAE emulsion to stir to form a slurry, inject it into a mold, and release the slurry after hardening to form an external wall insulation The protective layer of the board. Use cement mortar to bond the protective layer on the upper surface of the insulation layer, pressurize and shape, dry and cure, and after the cement mortar hardens, a cement polystyrene particle fireproof external wall insulation board is formed.
