Abstract

The invention relates to a foaming cement composite vacuum heat insulation plate comprising a vacuum heat insulation plate and foaming cement which covers the periphery of the vacuum heat insulation plate. The vacuum heat insulation plate 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 covers the periphery of the high strength air resistance film. The thickness of the interface mortar is 2 millimeters to 3 millimeters. The foaming cement composite vacuum heat insulation plate and a preparation method of the foaming cement composite vacuum heat insulation plate have 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 good fireproof performance is achieved.

Description

technical field [0001] The invention relates to a composite thermal insulation material for building exterior walls, in particular to a foamed cement composite vacuum thermal insulation board and a preparation method thereof. technical background [0002] At present, the fire rating of common vacuum insulation boards can reach the national standard of non-combustible or flame-retardant, and the thermal insulation effect is good. However, they are easy to be scratched during the construction process, hollowing and air leakage occur, and the utilization rate is greatly reduced. Contents of the invention [0003] The object of the present invention is to overcome the damage phenomenon of the vacuum heat insulation material during the construction process, and provide a foamed cement composite vacuum heat insulation board with convenient construction, good heat insulation effect, and A-level fire resistance. The technical solution of the present invention is: a foam cement co...
