Embodiment Construction

[0019] Below according to example the present invention is further described:

[0020] like figure 1 and figure 2 As shown, a vacuum insulation panel suitable for the construction field includes a core material 1, a high-performance barrier film 2 and an inorganic protective layer 3, the high-performance barrier film 2 is coated on the outer surface of the core material 1, and the inorganic protective layer 3 coated on the outer surface of the high performance barrier film 2.

[0021] The core material 1 can generally adopt perlite, turpentine, obsidian, pearlite, or diatomite with a particle size of 50-2000, and the core material 1 adopts perlite, turpentine, Obsidian, pearlite, diatomaceous earth or wollastonite.

[0022] Its main component is silicon dioxide containing 50-90%, and the rest is inorganic impurities of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, or P2O5.

[0023] like figure 2 As shown, the high-performance barrier film 2 is successively composed of polyethylene...

Abstract

The invention relates to a vacuum insulation panel suitable for the field of building. The vacuum insulation board comprises a core material, a high performance barrier film and an inorganic protective layer. The high performance barrier film is coated on an external surface of the core material; the inorganic protective layer is coated on an external surface of the high performance barrier film. The core material includes main components of silica and oxide inorganic impurities; the high performance barrier film includes a polyethylene layer, a polyethylene glycol terephthalate layer, a nylon layer and an aluminium foil layer from inside to outside; and the inorganic protective layer includes silicic acid, mineral filler and inorganic pigment. The vacuum insulation panel of the invention has characteristics of resistance to physical and chemical destroy, insensitive powder to vacuum degree, long service life, hard rebound deformation, better flame resistance and more suitability for building insulation and energy saving.

Description

technical field [0001] The present invention relates to building panels, in particular to a vacuum insulation panel. Background technique [0002] Vacuum Insulation Panel (VIP panel for short) is one of the vacuum insulation materials. It is composed of filling core material and vacuum protection surface layer. It can effectively avoid the heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, less than 0.004w / m.k. It has the characteristics of environmental protection and high efficiency and energy saving. It is currently the world's most Advanced high-efficiency insulation materials. Vacuum insulation panels are heat-insulating and environmentally friendly materials with excellent heat-insulating performance, and there is no pollution in the process of manufacture, use and post-use treatment. It meets the revolutionary requirements for the future development of CFC thermal insulation products. Compared with other materials, with its ...
