Abstract
The utility model discloses a sound absorption composite board. The sound absorption composite board comprises a gypsum board layer which is arranged on the upper layer and a sound absorption layer which is arranged on the lower layer. The sound absorption composite board is characterized in that the sound absorption layer is provided with a sound absorption base board. The sound absorption base board is connected with the sound absorption layer in a sticky mode. Sound absorption holes are formed in the sound absorption base board and arranged in a staggered mode. Due to the fact that the sound absorption holes are formed in the sound absorption base board and arranged in a staggered mode, most sound is absorbed by the sound absorption holes, the sound absorption base board is a centrifuge glass wool board or a polyester fiber board, the sound absorption holes are arranged in a triangle shape, and the sound absorption effect is more obvious.
Description
Technical field
The utility model relates to architectural decoration material field, and it is good to relate in particular to a kind of sound-absorbing effect, is suitable for the sound-absorbing composite board that indoor decoration is used.
Background technology
In recent years, along with the propelling of urban-rural integration, farm building is also more and more.When selecting building and ornament materials, will reasonably select according to different needs.People like looking in the environment of clamour a quiet again.So when selecting constructional materials, especially in the selection of composite plate, usually require sound-absorbing effect preferably, so sound-absorbing composite board more and more is subject to people's favor.In theory, general object all has sound-absorbing effect, but we are average absorption, in infinitely-great space, puts the sheet material that an infinitely-great material surpasses 30dB between sound source and the measured point and just is called sound-absorbing sheet material.Sound-absorbing sheet material is generally high density material.Sound is a kind of wavy energy, needs medium to propagate.Sound is when the same Propagation, and Media density is larger, and spread speed is faster.It is exactly to stride medium to propagate that the another kind of sound is propagated.Namely from a kind of medium, the critical contact face that passes two media enters another kind of medium, and at this moment, the transmission essence of acoustic energy is the transmission of Oscillation Amplitude.When striding the medium propagation, the density of two media differs larger, and the loss of acoustic energy is larger.And in the practical application, air is activity space under the human normality, is generally the very high material of density so differ larger material with atmospheric density.Density is higher, and sound-absorbing effect is better.The sheet material that such material is made is called sound-absorbing sheet material.The sound of the not all frequency of abatvoix sheet material can both intercept, and object has natural reonant frequency, and near the sound of object resonance frequency, the sound-absorbing effect of sound-absorbing sheet material significantly reduces.Sound-absorbing sheet material has the difference every airborne sound and chatter.Airborne sound sound-absorbing sheet material, what namely intercept is the sheet material of the sound propagated in air.What chatter sound-absorbing sheet material namely intercepted is at stiffening member, such as sheet material and the system of the sound propagated in the steel concrete monolithic house.Having in the market some sound-absorbing sheet materials that rubber layer, damping material or deadening felt etc. are installed between two boards makes, adopt this method, in short-term, can improve to a certain extent sound-absorbing effect, but its sound-absorbing effect can reduce gradually along with the time.Because the material such as rubber can be slowly aging in air, cause its gradually hardening and lose elasticity, the caoutchouc elasticity forfeiture will cause the sound-absorbing effect variation.So such sound-absorbing sheet material can not guarantee long-time excellent sound-absorbing effect.
Publication number is CN 201495683U, comprises gypsum plank for the Chinese patent literature of 2010.06.02 discloses a kind of sound-absorbing composite board in open day, and it is characterized in that: be stained with the damping sound insulation felt at described gypsum plank face, the opposite side of this damping sound insulation felt is sound-absorbing cloth.On this patent documentation damping sound insulation felt sound-absorbing cloth is set directly, the volume limited that sound-absorbing cloth and damping sound insulation felt absorb can not fundamentally play good sound-absorbing effect.
The utility model content
The utility model is intended to provide a kind of sound-absorbing effect good sound-absorbing composite board for the poor defective of above-mentioned prior art sound-absorbing effect.The utility model can effectively absorb noise by the sound-absorbing backing plate is set, and has the good characteristics of sound-absorbing effect.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
Sound-absorbing composite board comprises the gypsum flaggy of lower floor and the sound absorbing layer on upper strata, it is characterized in that: be provided with the sound-absorbing backing plate on the described sound absorbing layer, the sound-absorbing backing plate is bonding the connection with sound absorbing layer, has sound-absorption hole on the described sound-absorbing backing plate, described sound-absorption hole interlaced arrangement.
Described sound-absorption hole shape triangular in shape.
Described sound-absorbing backing plate is centrifugally glass-wool plate or polyester fiber board.
The thickness of described sound-absorbing backing plate is 10-15mm.
Centrifugally glass-wool described in the utility model is that the glass that will be in molten condition carries out the filamentary material that fibrillatable spraying thermosetting resin is made with centrifugal winding-up, have the advantages such as fire-retardant, nontoxic, corrosion-resistant, that unit weight is little, coefficient of thermal conductivity is low, chemical stability is strong, hydroscopicity is low, hydrophobicity is good, especially a kind of good damping material.
Polyester fiber described in the utility model is that the polyester that formed by organic dibasic acid and dihydroxylic alcohols polycondensation is through the synthetic fibers of spinning gained.
During use, sound passes on the sound-absorbing backing plate of the superiors, owing to have sound-absorption hole on the sound-absorbing backing plate, and sound-absorption hole interlaced arrangement, most sound will be absorbed by sound-absorption hole, the sound-absorbing backing plate is centrifugally glass-wool plate or polyester fiber board, and sound-absorption hole arranges shape triangular in shape in addition, and sound-absorbing effect is particularly evident.Pass the sound-absorbing backing plate of the superiors when sound after, pass on the sound absorbing layer, sound absorbing layer can absorb sound again again, has excellent sound-absorbing effect.
The beneficial effects of the utility model are mainly manifested in the following aspects:
One, have sound-absorption hole owing on the sound-absorbing backing plate, and the sound-absorption hole interlaced arrangement, most sound will be absorbed by sound-absorption hole, and the sound-absorbing backing plate is centrifugally glass-wool plate or polyester fiber board, and sound-absorption hole arranges shape triangular in shape in addition, and sound-absorbing effect is particularly evident.
Two, after sound passes the sound-absorbing backing plate of the superiors, pass on the sound absorbing layer, sound absorbing layer can absorb sound again again, has excellent sound-absorbing effect.
Three, the thickness of sound-absorbing backing plate is set to 10-15mm, when saving cost, also can play good sound-absorbing effect.
