Abstract
The utility model relates to a punching perforated plate which comprises a perforated core; a punching panel and a punching bottom plate are composited on two end surfaces of the perforated core; sound absorption paper is arranged between the panel and the perforated core; and the bottom plate and the perforated core are glued by hot melting adhesive. The punching perforated plate has simple structure and light weight, is good in sound absorbing effect as the hole of the sound absorption paper is not blocked, and is widely used in engineering fields such as ceiling boards, decoration and the like.
Description
Technical field
The utility model relates to a kind of decorative panel of constructional materials, relates in particular to a kind of punching cellular board.
Background technology
At present, raising along with rapid development of economy and people's living standard, people have proposed the requirement of acoustics to most building, not only showing has such requirement to buildings such as concert hall, grand theater, assembly halls, at speech room, classroom, singing-hall even the local-style dwelling houses of school, railway car etc. such requirement is arranged all also.In the prior art, for the requirement of satisfying acoustics normally in the framework of wooden or metal filled glass fiber cotton etc. make porous material, and then cover metal sheet or other sheet material that is provided with sound-absorption hole, thereby constitute sound absorbing layer.This structure complex procedures, cost increases, and damping material forms dust and contaminated environment easily in the work progress at the scene.Also there are some Related products to come out in recent years, but in its technical indicator: not high, unsatisfactory aspect weight, intensity, outward appearance, the sound-absorbing effect Comprehensive Assessment, as can not to satisfy people demand.
In addition, the sound absorbing paper in the sound-absorbing cellular board of the prior art is substantially all stopped up by PUR, to such an extent as to can't sound-absorbing, lost the effect of sound-absorbing.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of simple in structure, production technology is simplified, the punching cellular board that cost is low.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of punching cellular board, comprise the honeybee core, described honeybee core both ends of the surface are compounded with punching panel and punching base plate, be provided with sound absorbing paper between described panel and the described honeybee core, described base plate and honeybee core are bonding by PUR.
According to another embodiment of the present utility model, the punching cellular board comprises that further described sound absorbing paper top is filled with PUR.
According to another embodiment of the present utility model, the punching cellular board comprises that further described sound absorbing paper is a nonwoven.
According to another embodiment of the present utility model, the punching cellular board comprises that further described panel and described base plate are aluminium sheet.
The utility model has solved the defective that exists in the background technology, and the utility model is simple in structure, light weight, because the hole of sound absorbing paper is not stopped up, sound-absorbing effect is good, and is widely used in engineering fields such as suspended ceiling, decoration.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, honeybee core, 2, panel, 3, base plate, 4, sound absorbing paper.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of punching cellular board comprises honeybee core 1, and described honeybee core 1 both ends of the surface are compounded with punching panel 2 and punching base plate 3, are provided with sound absorbing paper 4 between described panel 2 and the described honeybee core 1, and described base plate 3 is bonding by PUR with honeybee core 1.For improving the sound-absorbing efficient of sound absorbing paper 4, described sound absorbing paper 4 tops are filled with PUR.And sound absorbing paper 4 is preferably nonwoven.In addition, for reducing the weight of punching cellular board, described panel 2 is an aluminium sheet with described base plate 3.
Manufacturing process of the present utility model is as follows:
The hole of punching press some on base plate 3 and panel 2 at first, this hole is according to the area needs of sound-absorbing, then sound absorbing paper 4 heating are affixed on the panel 2, then punching place of being stamped sound absorbing paper 4 on the panel 2 is clung with gummed paper, spray PUR on the panel 2 after having pasted, gummed paper is peeled off, on panel 2, put honeybee core 1, same spraying PUR on the base plate 3, base plate 3 and the panel 2 that has honeybee core 1 be compression moulding punching cellular board together.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the manual, must determine its technical scope according to the claim scope.
Claims (4)
1. a punching cellular board comprises the honeybee core, it is characterized in that: described honeybee core both ends of the surface are compounded with punching panel and punching base plate, are provided with sound absorbing paper between described panel and the described honeybee core, and described base plate and honeybee core are bonding by PUR.
