Said highly effective flame-retardant polyurethane foam layer is formed by polyurethane and fire retardant directly foaming bonding on inorganic plate, and highly effective flame-retardant polyurethane foam layer constitutes the composite polyurethane froth bed with inorganic plate.
The thickness of said highly effective flame-retardant polyurethane foam layer is 35mm~40mm, and its coefficient of thermal conductivity is 0.017 (W/mK)~0.020 (W/mK), and density is: 40kg/m 3~50kg/m 3
The coefficient of thermal conductivity of said highly effective flame-retardant polyurethane foam layer is 0.017W/m.k~0.020W/m.k, and density is 40Kg/m 3~50Kg/m 3
Said inorganic plate is cement or marble.
The thickness of said inorganic plate layer is 2.5~3mm.
Said composite polyurethane froth bed is fixed on basic unit's body of wall through crab-bolt.
Said bottom plastering mortar layer and surface layer plastering mortar layer gross thickness are 3mm~5mm, and the centre accompanies alkali-resistant glass fibre grid layer of cloth.
The material of said finish coat is a polymer mortar.
The utility model is applied to the heat-insulation system of external wall with polyurethane foam board, adopts the composite polyurethane foam, on the inorganic plate face; The expansion type flame retardant and the direct foaming of polyurethane of no halogen family element are formed; Its high insulating effect, good flame resistance, convenient and practical.This fire retardant prescription is seen patent No. CN200510012018.4.
Between plastering mortar layer and finish coat, be added with the alkali resistant glass fibre open weave cloth layer, make finish coat be not easy cracking, increase pulling force each other.
The advantage of the utility model is: provide a kind of employing to contain the heat-insulation system that external wall insulation that efficient flame-retarding agent processes is processed; It has many outstanding advantages; Like high-efficiency fireproof, fire resistance height, good heat insulating, life-span length, halogen-free flameproof, safety and environmental protection etc., can not pollute environment.
