Metal-based sound-absorbing and thermal insulation decorative panels

Abstract

The invention discloses a metal-based sound absorption and heat preservation decoration board. A composite board takes a metal base board as a base board, a plurality rows of sound absorption holes are evenly distributed on the metal base board, the four edges of the upper surface of the metal base board are provided with a frame, and the surface of the metal base board is provided with a metal protecting layer; a non-woven sound absorption board layer, a sound absorption and heat preservation material layer and an aluminum foil layer are sequentially composited in the frame arranged on the metal base board; a plurality columns of cavities are formed between the non-woven sound absorption board layer and the sound absorption and heat preservation material layer, and the sound absorption and heat preservation material layer is shaped like a flat board block structure or a continuous arc-shaped wave structure. The metal-based sound absorption and heat preservation decoration board mainly has the following advantages of being good in sound insulation, noise reduction and heat preservation effect, high in strength, stable, indeformable, scientific and compact in structure, convenient and fast to install, good in fireproof performance and dampproof performance, capable of preventing worm damage, not capable of generating harmful gas and buckling deformation, firm, durable, good in comprehensive performance, especially suitable for places where people flow is large or busier places and capable of optimizing environment to enable people in the environment to feel comfortable and achieving the better application value.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a sound-absorbing and heat-retaining decorative board with metal as the base material. Background technique [0002] In the north of our country or in busy places such as hospitals and airports where heating is required, thermal insulation decorative panels and noise reduction facilities are often laid indoors. The thermal insulation decorative panels mainly include ceiling and curtain wall panels. Ordinary ceiling and curtain wall panels often use aluminum alloy panels. Or gypsum board is used in combination with simple sound insulation materials. This combination structure has many defects: poor sound absorption and heat preservation effect; because it is not a composite material, the structure is loose; and due to weight considerations, its thickness must be relatively thin. After a long time of installation, it is prone to deformation, arching or warping. When the deformat...

Problems solved by technology

[0005] As a further explanation of the above scheme, since the metal-based sound-absorbing and heat-insulating decorative board adopts a metal-based composite board, the non-woven sound-absorbing hole plate and the sound-absorbing and heat-preserving material layer are made of lightweight materials, but have a certain strength. , overcomes the defect that the metal substrate is thin and easy to deform, and at the same time has the effect of sound absorption and heat preservation. After the sound wave is divided through the sound-absorbing hole, the sound wave is absorbed by the non-woven sound-absorbing board layer, which greatly attenuates the noise; In addition to keeping warm, it also plays a role in further strengthening the sound insulation, further attenuating the noise to a minimum
