Abstract
The utility model discloses a honeycomb composite sound-absorbing board with a honeycomb core layer covered with a sound-absorbing short fiber, and belongs to the field of building materials. The honeycomb composite sound-absorbing board comprises a honeycomb core and panels fixed on the two sides of the honeycomb core, wherein the inner walls of honeycomb holes of the honeycomb core are provided with fibrous feathers. Due to the fibrous feathers on the inner walls of the honeycomb holes, the vibration of sound wave causes frictions between fibers to convert sound energy into heat energy, so that the sound-absorbing effect is greatly improved. Furthermore, the honeycomb core is made of porous aramid paper, so that the honeycomb composite sound-absorbing board has the advantages of high strength and light weight.
Description
Technical field
The utility model belongs to building materials field, is specifically related to the honeycomb composite sound-absorbing plate of a kind of honeycomb sandwich layer with the sound-absorbing short fiber.
Background technology
Sound-absorbing sheet material is classified as follows by its design feature in the prior art:
1. sound-absorbing wedge: the sound-absorbing wedge is a kind of special sound absorption construction material that is used for strong sound absorption, adopts the cutting of porosity (or fibroid) forming materials, is made into taper or wedgelike sound absorber, and is strong indeformable.The sound-absorbing wedge is applicable to the air blast environment, and is mainly to liking the high-quality sound attenuation room, more effective to the absorption of low frequency, can eliminate standing wave, reaches the requirement of stopping echo, and low cut-off frequency sound absorption coefficient is greater than 0.99.V-type, the W type sound-absorbing wedge of processing with polyester compared with common wedge absorber has characteristics such as the little price of the volume of taking is more reasonable.
2. diffuser abatvoix (three-dimensional diffused abatvoix): the diffuser abatvoix is except all functions with plane abatvoix; Can also carry out the conduction of different angles to sound wave through its three-dimensional surface, eliminate the blind area of sound wave in diffusion process, improve tonequality; The balance sound equipment; The skiving stress weakens high pitch, and bass is compensated.Open form is like three-dimensional triangle or columniform groove in the medium density fibreboard front, and the structure sound absorption material of circular hole is opened at the back side, and facing sprays paint (can select color by customer requirement), and the back of the body pastes fireproof acoustic cloth.Be mainly used in TV station, cinema, opera house, concert hall, conference centre, sports palace, tone chamber, household, market, hotel, Karaoke, pub, dining room etc.
3. aluminium honeycomb perforation abatvoix: the structural texture of aluminium honeycomb perforation abatvoix is perforated panel and perforation backboard, relies on the direct bonding aluminium honeycomb sandwich construction that becomes of high-quality bonding adhesive and aluminium honeycomb core, sticks one deck sound-absorbing cloth between honeycomb core and panel and backboard.Because the honeycomb core in the honeycomb aluminium sheet is separated into numerous closed cells; Stoped air to flow; Sound wave is hindered, improved sound absorption coefficient (can reach more than 0.9), improved sheet material self intensity simultaneously; It is bigger that the size of monolithic sheet material can be accomplished, further strengthened design freedom.Can design according to room acoustics, carry out different perforated percentage designs, the sound-absorption coefficient in certain scope inner control combining structure had both reached design effect, can rationally control cost again.Through control punch aperture, pitch-row; And can change perforated percentage according to client's instructions for use, < 30%, specifications such as ∮ 2.0, ∮ 2.5, ∮ 3.0 are generally selected in the aperture for use to the maximum puncture rate; The backboard perforation requires identical with panel, and sound-absorbing cloth adopts the sound absorption materials such as nonwoven of high-quality.
4. wooden perforation abatvoix: the hole gypsum plank has the cylindrical orifice that runs through the gypsum plank front and back, pastes back of the body cover material material with gas permeability and the sound absorption material that can absorb incident acoustic energy etc. at the gypsum plank back side and organizes a performance and form.Sound absorbing mechanism is the hole that material internal has small in a large number connection, and sound wave can go deep into material internal along these holes, with material generation rubbing action acoustic energy is converted into heat energy.The sound absorption characteristics of porous absorption material are that the sound absorption coefficient that increases along with frequency increases gradually, this means that low frequency absorbs and do not have high frequency absorption good.
Summary of the invention
It is good that the purpose of the utility model provides a kind of sound-absorbing effect, and intensity is high, the honeycomb composite sound-absorbing plate of light weight.
The technical scheme of the utility model is: a kind of honeycomb sandwich layer is covered with the honeycomb composite sound-absorbing plate of sound-absorbing short fiber, comprises honeycomb core and is fixed on the panel of honeycomb core both sides, and it is characterized in that: the honeycomb hole inwall of said honeycomb core has fibre fluff.
Further, said fibre fluff is vertical with the honeycomb hole inwall.
Further, said honeycomb core is processed by the aramid fiber paper with porous.
The utility model compared with prior art has following advantage:
1, because the honeycomb hole inwall has fibre fluff, the vibration of sound wave makes between the fiber and rubbing action to take place acoustic energy is converted into heat energy, and sound-absorbing effect is improved greatly.
2, because honeycomb core is processed by the aramid fiber paper with porous, has the advantage of intensity height, light weight.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical profile structural representation of Fig. 1.
Reference numeral is respectively among the figure: 1 honeycomb core, 2 panels, 3 fibre fluffs.
The specific embodiment
The following exemplary embodiment of the present invention that is limited claim and equivalent thereof to help complete understanding with reference to the description of accompanying drawing is provided.Below describe and comprise various specific detail, but that these only are considered to is exemplary to help understanding.Therefore, those of ordinary skill in the art will recognize, under situation about not departing from the scope of the present invention with spirit, can make various changes and modification to embodiment described here.In addition, for clear and succinct, the description of having omitted known function and structure.
Embodiment 1
A kind of honeycomb sandwich layer is covered with the honeycomb composite sound-absorbing plate of sound-absorbing short fiber, comprises honeycomb core 1 and is fixed on the panel 2 of honeycomb core 1 both sides, inhales at the honeycomb hole inwall of honeycomb core 1 and covers bonding short fibre fluff 3.Fibre fluff 3 is vertical with the honeycomb hole inwall.Said honeycomb core 1 is processed by the aramid fiber paper with porous.
Because the honeycomb hole inwall has fibre fluff 3, the vibration of sound wave makes and rubbing action takes place between the fiber acoustic energy is converted into heat energy, and sound-absorbing effect is improved greatly.And, has the advantage of intensity height, light weight because honeycomb core 1 is processed by the aramid fiber paper with porous.
