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. The thermal insulation layer of the cement polystyrene particle fire-proof external wall insulation board...
