Vacuum ion plating zirconium nitride copper decorative sheet

Abstract

The invention relates to a vacuum ion plating zirconium nitride copper decorative sheet. An external wall panel is connected with a base wall body through a keel. The external wall panel is formed bya surface decorative sheet layer cladding, a middle waterproof glass wool layer, and a dampproof aluminum foil veneer. Compared with the prior art, the decorative sheet is advantaged by good heat-insulating property, good decorative effect, low cost, and the decorative sheet is safe and durable.

Description

Technical field [0001] The invention relates to a wall decorative insulation board, in particular to a vacuum ion plating zirconium nitride copper decorative board. Background technique [0002] At present, the external wall insulation technology is divided into two types: plastering (wet method) and dry hanging (dry method) according to the construction method. The former has many construction procedures and is complicated. The insulation layer usually adopts B-grade flammable materials such as EPS and XPS. Poor, there are safety risks, [0003] Moreover, ordinary insulation boards are not waterproof, and the latter has high construction costs, and the weight of the overall structure increases the construction burden. [0004] Factory-made sound-absorbing panels solve the disadvantages of fabric soft packs. In addition to the wooden square frame, the resin-cured frame also solves the problem of the straightness and shape of the fabric sound-absorbing panel, but the wooden square is...

Problems solved by technology

However, the problem that gypsum is afraid of water and easy to absorb moisture has not been solved. Moreover, the strength of gypsum is not high, and it is easy to be damaged during transportation and installation, causing the material of the internal sound-absorbing layer to float. Grinding plaster requires a lot of manpower and material resources

[0006] The sound-absorbing performance of the sound-absorbing panel is within a certain range, and will vary with the size of the cavity behind the sound-absorbing panel. The larger the cavity, the better the sound-absorbing effect. No matter what kind of frame the current fabric sound-absorbing panel is made of, in order to ensure The flatness of the final surface layer must be leveled with a layer of gypsum board or plywood on the back of the sound-absorbing board as the base plate, and then glued with spray glue or gun nails, which consumes materials, labor and increases the wall. At the same time, the sound-absorbing function of the sound-absorbing panel will also be weakened with the disappearance of the cavity; if the cavity problem is solved by drilling holes on the substrate, it will consume a lot of manpower; at the same time, a large amount of glue spraying will destroy the environmental protection inside the building performance

[0007] In addition to the above shortcomings, no matter what method is used to make or install sound-absorbing panels, the biggest disadvantage is that the installed sound-absorbing panels cannot be freely replaced, disassembled, washed and recycled.

Once the surface fabric of the sound-absorbing panel is dirty or faded due to dust or time, the wall of the sound-absorbing panel can only be completely replaced, which not only increases the maintenance cost of the owner, but also destroys the replaced fabric sound-absorbing panel. secondary construction waste
