Foamed concrete building exterior wall insulation decoration integrated board

　　The invention relates to a heat insulation and decoration integrated board for a foamed concrete building external wall, which effectively solves the problems of complicated construction process, easy falling off, cracking, flammable, short life and unsafe. The method comprises the steps of: mixing Portland cement, polypropylene monofilament fiber, calcium stearate, redispersible rubber powder and sodium sulfate, adding water, triethanolamine, polycarboxylic acid and hydrogen peroxide in sequence, and molding the mold. Into the inner insulation layer; after mixing Portland cement, polypropylene monofilament fiber, lignin fiber, water-resistant rubber powder and hydroxypropyl methylcellulose, add water and polycarboxylic acid to mix, apply to the inner insulation layer On one side, it is a crack-resistant and anti-seepage putty layer; mix Portland cement, heavy calcium, quartz sand, polypropylene bundle monofilament fiber, water-resistant rubber powder and hydroxypropyl methylcellulose, add water, gather The carboxylic acid and the pigment are mixed and coated on the anti-cracking and anti-seepage putty layer to form an outer decorative layer. The invention has the advantages of light material, high strength, good heat preservation effect, low cost, safety, shape and long service life.
