Abstract

The invention relates to a high-strength PU compound A-level fireproof heat-insulating pate and a preparation method thereof and belongs to the field of polyurethane foam. The high-strength PU compound A-level fireproof heat-insulating pate comprises concrete glass fiber veneering layers and an anti-flaming polyurethane interlayer heat-insulating layer, wherein the upper and lower surfaces of the anti-flaming polyurethane interlayer heat-insulating layer are both provided with the concrete glass fiber veneering layers; the high-strength PU compound A-level fireproof heat-insulating pate is composed of double-sided concrete glass fiber veneering materials and the polyurethane interlayer heat-insulating layer; the adopted concrete glass fiber veneering materials are high-strength A-level incombustible materials; an interlayer polyurethane heat-insulating plate can meet B2-level or higher waterproof demand and is on-site foamed and prepared by using high-functionality combined polyether polyol and isocyanate; high-speed effective compound is realized on a continuous panel production line; the panel has higher strength; the flame retardant property wholly reaches A-level incombustible standard; the veneering materials are firmly bound to the heat-insulating interlayer, so that the service life is long; and the whole compression strength is high.

Description

technical field [0001] The invention relates to a high-strength PU composite A-grade fireproof insulation board and a preparation method thereof, belonging to the field of polyurethane foam. technical background [0002] In recent years, with the implementation of my country's building energy-saving and thermal insulation policies, rigid polyurethane materials with good thermal insulation and use effects have been widely used in the field of energy-saving thermal insulation. Polyurethane composite panels are more and more used in building exterior walls, roof insulation and refrigeration equipment because of their construction is basically not affected by the environment and climate, and they are convenient for modular installation. They are especially suitable for old house renovation projects. Because the untreated polyurethane composite material is particularly easy to burn, it brings many safety hazards to the construction process and use process. Once a fire breaks out...
