Abstract
The invention provides a compounding process of a sound-absorption honeycomb plate. The compounding process comprises the following steps of (1) hanging an adhesive on an enough large glass platform; (2) uniformly coating the adhesive on a back plate; (3) dipping a honeycomb core in the adhesive coated on the glass platform, putting a surface of the honeycomb core without the adhesive in the back plate, covering nonwoven fabric on one surface with the adhesive to manufacture a half of a composite plate blank, and combining the half of the composite plate blank with a punched panel; (4) putting the manufactured composite plate blank of the step (3) into a vacuum device while keeping the punched surface upwards, and laminating the composite plate blank into a composite plate under the certain pressure. According to the composite plate manufactured by the compounding process disclosed by the invention, holes punched in the composite plate are communicated and absorb sound, alternative penetration of sound wave is formed in the holes of the honeycomb core, and finally residual sound is eliminated, so that the sound absorption effect of the composite plate is better.
Description
Technical field
The present invention relates to decorate sound-absorbing material, more specifically, relate to honeycomb sound-absorbing composite plate and combination process thereof.
Background technology
In construction and decoration, as classroom, assembly hall, cinema or some amusement and recreation places, in interior decoration, in order to reduce room noise, generally when building finishing, just at interior metope or ceiling sound absorbing layer is installed.Cellular board is the sheet material of a kind of lightweight, high rigidity, is used as the sound absorbing layer material widely.The production technology of the honeycomb punching abatvoix on the market all is in the nonwoven cloth proofing now, client's needs have so just visually been satisfied, but there is drawback in this production technology, will the hole on the cellular board be shut etc. after the glue curing, the sound-absorbing effect of abatvoix is had a greatly reduced quality like this, and sound-absorbing effect is relatively poor.
Summary of the invention
At above-mentioned defective of the prior art, the invention provides a kind of honeycomb sound-absorbing composite plate and combination process thereof.
Technical scheme of the present invention: honeycomb abatvoix combination process may further comprise the steps:
(1) glue is hung over one enough on the big glass platform; (2) the backboard uniform gluing; (3) be stained with the glue that is coated on the glass platform with honeycomb core, do not have the honeycomb core face of viscose glue to be put into the backboard the inside, the one side of viscose glue covers nonwoven, makes half of composite plate blanks, and the panel sets with hole punch lumps together then; (4) the two halves composite plate blanks that makes in the step (3) is put into vacuum plant, punch side upwards under certain pressure, is pressed into composite plate with described composite plate blanks.
Preferably, described glue is polyurethane glue.
Preferably, the specification of described nonwoven is 40 grammes per square metres.
Preferably, described honeycomb core material is aluminium, PC plastics or fiberglass.
Preferably, described backboard is aluminium sheet.
Preferably, the pressure described in the step (4) be-0.075～-0.06MPa.
Preferably, it comprises the upper, middle and lower-ranking structure, and described middle level structure is honeycomb core plate, and the upper and lower layer of described honeycomb core plate is respectively aluminium sheet.
Preferably, be provided with nonwoven between described honeycomb core plate and the described aluminium sheet.The present invention adopts nonwoven, and not only bond effect is good, and glue can not block the hole, guarantees that the hole of honeycomb core plate communicates.
Preferably, the hole on the described honeycomb core plate all communicates.Hole on the honeycomb core plate of the present invention all communicates, and these holes can be fallen acoustic absorption, reaches the good sound absorption effect.
The technology of honeycomb abatvoix provided by the invention is to be stained with glue with honeycomb core, and nonwoven is placed in the sheet forming that the honeycomb core that will be stained with glue again is placed on the nonwoven, and so not only bond effect is good, and glue can not block the hole; The hole of the composite plate that is combined into this technology all communicates, and acoustic absorption is fallen in these holes, and the hole of honeycomb core forms sound wave interts, and the lingering sound that finally disappears is so the sound-absorbing effect of this plate is better.
