Abstract
The utility model belongs to the technical field of aluminum processing, and in particular relates to a mute aluminum plate which is formed by compositing two layers of aluminum plates of special thickness through continuous composite hot pressing. An upper layer is a face layer aluminum plate, a lower layer is a bottom layer aluminum plate, the thickness of a face layer aluminum place is 0.1-1mm, the thickness of a bottom layer aluminum plate is 0.1-3mm, and an adhesion agent layer is arranged between the face layer aluminum plate and the bottom layer aluminum plate. The mute aluminum plate removes a flammable polyethylene middle layer, does not contain organic matters, and is high in fire protection grade. Most of reflection waves produced by the two layers of aluminum plates can be offset, so that the mute aluminum plate is good in mute effect and is suitable for popularization and application.
Description
Technical field:
The utility model relates generally to a kind of aluminium sheet, particularly relates to a kind of quiet aluminium sheet, is applied to the industries such as architectural decoration, belongs to the aluminium sheet manufacture field.
Background technology:
Be the Aluminiumplastic composite panel that plastic-aluminum combined plate technique is made near technology of the present utility model at present, Aluminiumplastic composite panel is by two-layer aluminium sheet and middle polyethylene sandwich layer are composited through continuous hot-press up and down.
The characteristics of aluminium-plastic panel: the aluminium-plastic panel gross thickness is 3～5mm, and two-layer aluminium sheet is the aluminium sheet of same thickness up and down, and aluminium plate thickness is usually thinner, and between 0.1mm and 0.5mm, the centre is the polyethylene sandwich layer.Surface aluminium sheet baking vanish adopts roller coating technology, normally fluorocarbon baking varnish and enamel polyester paint.Obtain with the same appearance effect of pure roller coat aluminium sheet under, other has quiet effect.
But its domestic aluminium-plastic panel that adopts has several shortcomings:
(1), fire-protection rating is poor, present technology can only reach the B1 level basically, in the situation that naked light occurs, aluminium-plastic panel can burn and produce the melting drip phenomenon, fire suppression is possible hardly.The reason that produces this shortcoming is that the polyethylene sandwich layer itself has high heating value, and burning-point only has degree more than 300, in case run into naked light meeting self-burning and combustion-supporting, polyethylene also can fly with naked light when melting drippage everywhere simultaneously, be equivalent to sowing kindling material, therefore use the exterior building of aluminium-plastic panel even catch fire from top, the last intensity of a fire also can spread to whole building and whole exterior wall is burnt, so also remedy to fire-fighting and bring huge difficulty, this point that the fire fact of China and foreign countries' aluminium-plastic panel building is verified.
(2), the baking vanish quality of roller coat compares with the large factory in kind and the world that there is a big difference, mostly present domestic roller coating production line is low side thin plate production line, some function advanced persons' baking vanish can't be made, and because domestic price war is very violent, so the technical level of domestic production line is in low side all the time.
Summary of the invention:
Goal of the invention:
The utility model has proposed a kind of quiet aluminium sheet for the variety of issue that exists in the above-mentioned prior art, has effectively overcome the problem of the aspects such as above-mentioned fire-protection rating baking vanish low and roller coat is of poor quality.
Technical scheme:
The utility model is realized by following scheme:
A kind of quiet aluminium sheet comprises surface layer aluminium sheet and bottom aluminium sheet, and the upper strata is the surface layer aluminium sheet, and lower floor is the bottom aluminium sheet, and the thickness of surface layer aluminium sheet is 0.1～1mm, and the thickness of bottom aluminium sheet is 0.1～3mm, is adhesive layer between surface layer aluminium sheet and the end aluminium sheet.
Advantage and effect:
The utility model proposes a kind of quiet aluminium sheet, have following advantage:
(1), the difference of the utility model and prior art is to have cancelled polyethylene middle layer, compound two-layer special thickness pure aluminum plate only, solved like this problem of fire-protection rating, by the different arrangement of thickness between each layer aluminium sheet, utilize the effect of cancelling each other between each layer aluminium sheet acoustic reflection to reach mute function simultaneously.
(2), the continuous hot-press hybrid system that adopts of this product also has very strong improvement than the hot pressing hybrid system that aluminium-plastic panel adopts, the compound ability of the up-down rollers system of this production line is strong, the aluminium plate thickness scope that can adapt to is large, between 0.1～3mm.
Description of drawings:
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1, surface layer aluminium sheet; 2, bottom aluminium sheet; 3, adhesive layer.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
The utility model provides a kind of quiet aluminium sheet, as shown in fig. 1: be the quiet aluminium sheet of bilayer, adopt continuous hot-press hybrid system production line to produce, it is characterized in that: this quiet aluminium sheet is comprised of the aluminium sheet of two-layer special thickness, namely the aluminium sheet by two-layer special thickness becomes through continuous compound hot pressing complex group, the upper strata is surface layer aluminium sheet 1, and lower floor is bottom aluminium sheet 2; Described special thickness refers to: the thickness of surface layer aluminium sheet 1 is between 0.1～1mm, and the thickness of bottom aluminium sheet 2 is between 0.1～3mm; Be adhesive layer 3 between surface layer aluminium sheet 1 and the bottom aluminium sheet 2, surface layer aluminium sheet 1 and bottom aluminium sheet 2 are bonded together by cementing agent.
The high-end aluminum deck that surface layer aluminium sheet 1 adopts from external import, thickness is between 0.1～1mm, the bottom aluminium sheet is domestic aluminium sheet, thickness is between 0.1～3mm, with this two-layer aluminium sheet through the continuous compound thermal pressing production line production board that is composited, this plate possesses mute function, and this panel is because used the high-end aluminum deck of external import, so when possessing mute function, also have various high-end baking vanish performances, this plate is because be that two-layer aluminium sheet forms simultaneously, cancelled inflammable polyethylene middle layer, do not contained organic matter, so this plate fire-protection rating is the A1 level.
This quiet aluminium sheet that the utility model provides, it is the quiet aluminium sheet joint product of a kind of bilayer, be used for various building and the structure internal and external ornaments that ambient sound is had relatively high expectations, surface layer aluminium sheet 1 is the Decorative Aluminium Plate with various difference in functionalitys, the intermediate layer is adhesive layer 3, and bottom aluminium sheet 2 is ordinary aluminum plates.The thickness of surface layer aluminium sheet 1 and bottom aluminium sheet 2 is determined through special consideration, when being transmitted on every layer of aluminium sheet, sound wave all can produce new back wave, this product is by the thickness of calculative determination surface layer aluminium sheet 1 and bottom aluminium sheet 2, the major part so that the back wave that this two-layer aluminium sheet produces can be cancelled each other, thus reach quiet effect.
