Abstract
The invention relates to a low-alkaline adhesive mortar composite vacuum heat insulation plate. The low-alkaline adhesive mortar composite vacuum heat insulation plate comprises a vacuum heat insulation plate, and low-alkaline adhesive mortar clad on the periphery of the vacuum heat insulation plate, wherein the vacuum heat insulation plate comprises core material, a high-strength gas blocking film and interface treating mortar; the high-strength gas blocking film packs the periphery of the core material; the high-strength gas blocking film and the core material are packaged through vacuuming; the periphery of the high-strength gas blocking film is coated with the interface treating mortar; the thickness of the interface treating mortar is 0.1-3 mm. The low-alkaline adhesive mortar composite vacuum heat insulation plate has the advantages that the phenomenon that traditional vacuum heat insulation material is damaged during construction is overcome, and heat insulation plate is convenient for construction, the heat insulation effect is good, and the fireproof level is 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 ...
