Abstract

The invention relates to a modified cement polyphenyl granule composite vacuum insulated panel. The modified cement polyphenyl granule composite vacuum insulated panel is characterized by comprising a vacuum heat insulation panel and modified cement polyphenyl granule thermal mortar which covers the periphery of the vacuum heat insulation panel. The vacuum heat insulation panel comprises core materials, high strength air resistance film and interface mortar. The high strength air resistance film covers the periphery of the core materials and is encapsulated between core materials through vacuumpumping. A layer of interface mortar is coated on the periphery of the high strength air resistance film. The thickness of the interface mortar is 2 millimeters to 3 millimeters. The modified cement polyphenyl granule composite vacuum insulated panel has the advantages that problem of damage and air leakage of the vacuum heat insulation plate in a work process is solved, construction and installation are convenient to achieve, heat retaining property, water resisting property, durability and freezing resistance are good, flame class is non-ignitable or fire-retardant and fireproof performance is good.

Description

technical field [0001] The invention relates to an external wall thermal insulation composite board in the construction field, in particular to a modified cement polystyrene particle composite vacuum heat insulation board and a preparation method thereof. Background technique [0002] At present, the common thermal insulation materials on the market include silicate thermal insulation materials, ceramic thermal insulation materials, rubber powder polystyrene particles, foamed cement boards, polystyrene thermal insulation boards, and Class A inorganic fireproof thermal insulation mortars. The above-mentioned organic thermal insulation material has good thermal insulation performance, but its flammability and fireproof performance are poor; the inorganic thermal insulation material has good fireproof performance, but its thermal insulation effect is not ideal. This limits the application of these insulation materials in the construction field. Contents of the invention [0...
