Embodiment 1

[0030] An inorganic thermal insulation mortar composite vacuum thermal insulation board comprises a vacuum thermal insulation panel and inorganic thermal insulation mortar covering its periphery.

[0031] The vacuum heat insulation board includes a core material, a high-strength gas-barrier film and interface mortar. The high-strength gas-barrier film is wrapped around the periphery of the core material, and is sealed with the core material by vacuum pumping. A layer of interface mortar is coated on the periphery of the high-strength gas barrier film, and the thickness of the interface mortar is 0.1-3 mm.

[0032] The core material is composed of ultrafine silica powder 40-90wt%, filler 0-45wt%, inorganic core material 0-20wt%, fiber 1-18wt%, getter 0-3wt%, vacuum stability Agent 0-3wt%.

[0033] The ultrafine silica powder is a mixture composed of one or more of silica fume, silica fume, volcanic ash, microsilica powder, perlite powder, and silica powder mixed in any proport...

Abstract

The invention relates to an inorganic thermal mortar composite vacuum heat insulation board which comprises a vacuum heat insulation board and inorganic thermal mortar which is coated on the periphery of the vacuum heat insulation board. The vacuum heat insulation board consists of core materials, a high-strength gas-blocking membrane and interface mortar, the high-strength gas-blocking membrane is coated on the periphery of the core materials and packed with the core materials in a vacuumizing mode, a layer of the interface mortar is coated on the periphery of the high-strength gas-blocking membrane, and the thickness of the interface mortar is 2-3 mm. The inorganic thermal mortar composite vacuum heat insulation board has the advantages of solving the problem that the vacuum heat insulation board is damaged and leaks air in the process of construction, being convenient to construct and install, and having good heat preservation performance, waterproof performance, durability and anti-freezing performance. A burning grade is non-inflammable or difficult to inflame, and fireproof performance is good.

Description

technical field [0001] The invention relates to an exterior wall thermal insulation composite board in the field of construction, specifically an inorganic thermal insulation mortar composite vacuum thermal insulation board. Background technique [0002] At present, although the fire rating of common vacuum insulation boards can meet the national standard for non-combustibility or flame retardancy, the 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 prevention. [0004] The technical solution of the present invention is: an inor...
