Abstract

The utility model relates to a decorative sound absorbing board, which comprises a base board. The outer surface of the base board is wrapped with a thin metal layer which is connected with the base board into integration. The middle parts of the two ends of the base board are provided with concave slots and the metal layer is distributed with a plurality of fine holes. The outer surface of the base board is wrapped with the thin metal layer and thus when the service life is long and the decorative sound absorbing board is adhered to dust, the dust can be cleaned. The rugged part of the decorative sound absorbing board caused by the long-time use can be wrapped in the metal layer. In addition, the holes arranged on the metal layer can not only be convenient for the sound absorbing board to absorb the sound and insulate the heat but also can be designed into various patterns with beauty to play an excellent decorative effect.

Description

Decoration acoustic absorption

Technical field

The utility model relates to a kind of decoration acoustic absorption, is meant a kind of decoration acoustic absorption with metal composite especially.

Background technology

Acoustical board is the new decorative material for building that integrates multiple functions such as light weight, sound-absorbing, fire prevention, heat insulation, decoration, and it is harmless, pollution-free, the green building material of favorable environment.Have these advantages just because of acoustical board, along with the develop rapidly of Building Trade in China, acoustical board progressively becomes a kind of general, popular ornament materials by former height, middle class, and its consumption increases year by year, and kind is renovation constantly also.

The weight of acoustical board is lighter, does not in use have sense of heaviness, gives people's safety, relieved sensation, the deadweight that can alleviate building, and also the primary raw material of acoustical board can be mineral wool, glass wool, rock wool etc., the fusing point height, and nonflammable, have higher fireproof performance.

At present, the decorative panel with acoustically effective has become a kind of general environmental friendly indoor ornament materials, and existing decoration acoustic absorption generally is that the external surface with substrate directly exposes, service time is long, some shortcomings will occur, occurs uneven as external surface, durability is relatively poor, yielding, also have, especially in the north, often blowing is strike-off, house the inside dust is more, will enclose one deck grieshoch on the clean acoustical board of former raw white and flavescence, blackening, influences attractive in appearance.

CN96228672.9 discloses the cotton acoustical board of a kind of resistance to deformation rock (ore deposit), comprises substrate 1, and substrate 1 back side is embedded with the fastening with it rigidity reinforcing rib that joins 2 reinforcing rib tops and is provided with overlay 3.Compare with general acoustical board commonly used; it has structurally had certain improvement; but; still have certain shortcoming; rigidity reinforcing rib 2 can not shield to the external surface of the substrate 1 of whole acoustical board; service time one is long, and the rough phenomenon that the external surface of acoustical board occurs can't be covered up.

How just can design a kind of decoration acoustic absorption, it had both kept original sound absorption, characteristics such as heat insulation, also have the intensity that increases acoustical board, prevent outer surface of substrate deformation, beautify the acoustical board external surface, the product of characteristics such as sweeping convenient for cleaning, a new problem is provided for the building materials researcher.The utility model designer has expected increasing by a thin metal layer at the external surface of decoration acoustic absorption through long term studies finally, so neither influences original characteristics, can also realize the characteristics that increase newly.

Summary of the invention

The purpose of this utility model is to provide a kind of decoration acoustic absorption, refer in particular to a kind of decoration acoustic absorption with metal composite, it can effectively prevent the decoration acoustic absorption panel yielding, easy to change, etc. the shortcoming of aspect, simultaneously, the fixing effect of reinforcement is played on the surface of whole acoustical board, prolonged the application life of decoration acoustic absorption.

For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of decoration acoustic absorption, comprise a substrate, and be coated with a thin metal layer at the external surface of described substrate, described metal level and substrate fuse.

Metal layer thickness and substrate thickness than between 1/10th and a thirtieth for good, selected substrate can be wherein a kind of such as mineral wool, glass wool, rock wool, selected metal level is the forming metal plate, can be aluminium alloy material, steel sheet, aluminium sheet or copper coin.

Described metal level can be directly to be bonded on the substrate, and the bonding agent that is adopted can be epoxy resin or white glue with vinyl.

Described metal level also can be to be plugged between substrate, and the grafting of metal level for convenience can have groove at the middle part at the two ends of described substrate, inserts in the groove both ends of metal level fixing then.Dark for convenience inserting can also further also have groove at the middle part, other both sides of substrate.

In order to make decoration acoustic absorption increase the effect that absorbs sound, prevents the metal level dewfall, can on metal level, be provided with several tiny holes, described hole can be the even or uneven surface that is distributed in metal level.

In order to increase the aesthetic feeling of decorative panel external surface, can be as required can be circle, pentagon, hexagon, pentalpha, oval wherein a kind of with the shape in hole.

For the powder in small, broken bits that prevents the mineral wool board in the decorative panel falls down, increase the effect of sound absorption simultaneously again, further between substrate and metal sheet, be provided with an extra play, described extra play can be mulberry paper or glass felt.

The use the beneficial effects of the utility model are: owing to coated a thin metal layer at the external surface of described substrate, long when service time, when being stained with dust on the decoration acoustic absorption, can putting on the skin and wipe away totally; Can avoid decoration acoustic absorption to use long and the generation uneven phenomenon that causes; Be located at the hole on the metal level, not only be convenient to acoustical board sound-absorbing, heat insulation, and can be designed to various patterns, create an aesthetic feeling plays decorative effect preferably; Between substrate and metal level, increase by an extra play, can prevent that not only the fine-powder of substrate from falling down, and increase the acoustically effective of acoustical board.
