Embodiment Construction

[0016] Below according to example the present invention is further described:

[0017] Such as figure 1 with figure 2 As shown, a high-strength and long-life vacuum insulation panel includes a core material 1, a high-performance barrier film 2 and a plastic protective layer 3, the high-performance barrier film 2 is coated on the outer surface of the core material 1, and the plastic protective layer 3 coated on the outer surface of the high performance barrier film 2.

[0018] The core material 1 can generally adopt perlite, turpentine, obsidian, white carbon black, pearlite, or diatomite with a particle size of 50-2000 mesh, and the core material 1 adopts perlite with a particle size of 50-1500 mesh , pitch rock, obsidian, white carbon black, pearlite, diatomaceous earth or wollastonite.

[0019] Its main component is silicon dioxide containing 50-90%, the rest is Al 2 o 3 , Fe 2 o 3 , CaO, MgO, K 2 O, Na 2 O, or P 2 o 5 of inorganic impurities.

[0020] Such as ...

Abstract

The invention relates to a vacuum insulation plate with high strength and long service life, which comprises a core material, a high-performance separation film and a plastic protection layer, wherein the high-performance separation film is coated on the outer surface of the core material, the plastic protection layer is coated on the outer surface of the high-performance separation film, the core material mainly comprises the following components of silicon dioxide and oxide inorganic impurities; the high-performance separation film sequentially comprises a polyethylene layer, an aluminum foil layer, a polyethylene glycol terephthalate layer and a nylon layer; and the plastic protection layer comprises phenolic resin or epoxy resin or urea resin or furan resin and other thermosetting resins and liquid nitrile rubber. The vacuum insulation plate provided by the invention has the characteristics of difficulty in bearing physical and chemical damages, insensitivity of powder to vacuum degree, longer service life, difficulty in rebound deformation, and higher mechanical strength.

Description

technical field [0001] The invention relates to a building board, in particular to a high-strength and long-life vacuum insulation board. 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...
