Abstract

The invention relates to a low-alkaline adhesive mortar compote vacuum heat insulation board which comprises a vacuum heat insulation board and low-alkaline adhesive 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 0.1-3 mm. The low-alkaline adhesive mortar compote vacuum heat insulation board has the advantages of overcoming a phenomenon that damage on traditional vacuum heat insulation materials occurs in the process of construction. The low-alkaline adhesive mortar compote vacuum heat insulation board is convenient to construct, good in heat insulation effect, and fireproof in class A.

Description

technical field [0001] The invention relates to an exterior wall thermal insulation composite board in the construction field, in particular to a low-alkali bonded mortar composite vacuum thermal insulation composite board and a preparation method thereof. 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] In order to overcome the defects of the prior art, the invention provides a low-alkali bonded mortar composite vacuum heat insulation board and a method for preparing the composite vacuum heat insulation board. The technical solution of the present invention is: a low-alkali bonded mortar composite vacuum heat insulation board, which ...
