Description

Technical Field

[0001] The utility model relates to the technical field of composite thermal insulation boards, in particular to a vacuum thermal insulation board built-in composite thermal insulation board. Background Art

[0002] Vacuum insulation panel is a new type of vacuum thermal insulation material, which is composed of a filling core material and a vacuum protective surface layer. It effectively avoids heat transfer caused by air convection, so the thermal conductivity can be greatly reduced to 0.002-0.005w / mk, which is about 1 / 10 of the thermal conductivity of traditional thermal insulation materials.

[0003] Applying vacuum insulation panels to the construction of building exterior walls can significantly reduce the thickness of the insulation layer and improve the thermal insulation effect. However, the existing application of vacuum insulation panels in the construction field is all done by external bonding, that is, the vacuum insulation panels are bonded on-site to the outside of the original insulation layer. During on-site construction, high-altitude operations to bond rectangular vacuum insulation panels piece by piece have problems such as complicated processes, high project costs, long construction periods, and high safety risk factors. At the same time, during the on-site bonding process, the vacuum protective surface of the vacuum insulation panel may be bumped or scratched, and accidental air leakage will significantly reduce the thermal insulation effect of the vacuum insulation panel.
