A building wall insulation composite board and its preparation method

The present invention relates to a wall insulation composite plate with a rigid polyurethane foam and a preparation method, and the insulation materials are energy-saving method for preparing building technology. One kind of a rigid polyurethane foam composite wall insulation panel comprising an inner core coated on the outer periphery of the inner core and the protective layer affixed to the upper and lower surfaces of the protective layer overlying the interface layer, the inner core of the vacuum insulation insulation board. One kind of a polyurethane foam wall insulation method for manufacturing a composite panel, comprising the steps of: a web interface Preparation: The polymer cement with a good flame-retardant coating produced on a substrate web interface; Second, the protective layer, and wall insulation made of polyurethane foam with a composite panel. This thermal insulating composite panel having very excellent thermal insulation, waterproof, heat insulating properties, can satisfy the requirements of the building 65% energy saving, high bond strength, convenient operation, after the wall has greatly increased the overall fire wall insulation system performance, can be widely used in the building walls, facades and roof insulation, insulation, waterproofing system.
