Abstract
The invention discloses a method for producing sound absorbing plates. An iron wire net is placed into a die to be pressed into the shape of wave, the iron wire net is powered on so that the iron wire net carries positive electricity, mixed material manufactured from epoxy resin powder with negative electricity and bast fiber with the length of 0.5-1 cm is sprayed to the iron wire net in an electrostatic powder spraying mode so that the iron wire net is wrapped in a layer of fluffy bast fiber, the iron wire net is fixed in the middle of a plate, and not only is the plate beautiful but also the plate has very good sound absorbing effect.
Description
Technical field
The present invention relates to sheet material manufacturing technology field, relate in particular to a kind of production method of sound-absorbing sheet material.
Background technology
Abatvoix is mainly used in that cinema, concert hall, museum, exhibition hall, library, hearing room, gallery, auction hall, sports palace, Conference Hall, multi function hall, hotel lobby, hospital, market, school, qin room, conference room, studio, recording room, karaoke chamber, bar, industrial premises, machine room, family's noise reduction etc. are had relatively high expectations to acoustic enviroment and the place of top grade decoration.
In prior art, the only metal sheet with mesh just of sound-absorbing metal plate, and directly expose in interior decoration, not only easily corrode dust stratification, and sound-absorbing effect is not good.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of sheet production method of good sound absorption function.
For solving the problems of the technologies described above, production method of the present invention comprises the steps:
Wire gauze is put into mould and be pressed into wavyly, the distance between described wavy wire gauze adjacent peaks and trough is 1.5-2cm, and adjacent two peak-to-peak distances of ripple are 3-4cm, and wire gauze width of mesh is 1-2mm
2,
To wire gauze energising, make wire gauze positively charged, voltage is 24V,
Adopt electrostatic powder spraying mode to spray to wire gauze the mixed material that bast fiber that electronegative epoxy powder and length are 0.4-0.6cm is made, described epoxy powder granular size is 50-100 μ m, the weight proportion of described epoxy powder and bast fiber is 9:5
Wire gauze after spray mixed material is put into after the mould suitable with shape, carried out hot pressing under the temperature condition of 70-90 ℃, form sound-absorbing slab, while starting hot pressing, to wire lath power-off, hot pressing time is 0.5 hour,
Coating adhesive on sound-absorbing slab trough separately,
Sound-absorbing slab is placed on plank, and bonding agent is fixed on sound-absorbing slab on the first plank, and described the first plank area is greater than sound-absorbing slab, and four edges expose,
Four edge butt plates are fixed with bonding agent respectively in four edges at plank, and the thickness of edge butt plate is identical with the distance between described sound-absorbing slab adjacent peaks and trough,
Coating adhesive on sound-absorbing slab crest separately and on four edge butt plates,
The second plank is covered on sound-absorbing slab, and fixing, and four edges of described the second plank just in time cover four edge butt plates.
Preferably, the thickness of described the first plank and the second plank is 3mm.
Preferably, described bonding agent is modified epoxy glue.
The invention has the beneficial effects as follows: the production method of abatvoix of the present invention, by the mixed material that spray epoxy powder and bast fiber are made on wavy wire gauze, make to wrap up on wire gauze the bast fiber that one deck is fluffy, above-mentioned wire gauze is fixed in the middle of sheet material, both attractive in appearance, reach again extraordinary sound-absorbing effect.
The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being realized object and effect, be explained in detail below in conjunction with embodiment.
The production method of sound-absorbing sheet material of the present invention comprises the following steps:
Wire gauze is put into mould and be pressed into wavyly, the distance between described wavy wire gauze adjacent peaks and trough is 1.5-2cm, and adjacent two peak-to-peak distances of ripple are 3-4cm, and wire gauze width of mesh is 1-2mm
2,
To wire gauze energising, make wire gauze positively charged, voltage is 24V,
Adopt electrostatic powder spraying mode to spray to wire gauze the mixed material that bast fiber that electronegative epoxy powder and length are 0.4-0.6cm is made, described epoxy powder granular size is 50-100 μ m, the weight proportion of described epoxy powder and bast fiber is 9:5
Wire gauze after spray mixed material is put into after the mould suitable with shape, carried out hot pressing under the temperature condition of 70-90 ℃, form sound-absorbing slab, while starting hot pressing, to wire lath power-off, hot pressing time is 0.5 hour,
Coating adhesive on sound-absorbing slab trough separately, described bonding agent is modified epoxy glue.Adopt this fixed form, can make wire lath under the effect of sound wave, slightly shake, improve sound-absorbing effect.
Sound-absorbing slab is placed on plank, and bonding agent is fixed on sound-absorbing slab on the first plank, and described the first plank area is greater than sound-absorbing slab, and four edges expose,
Four edge butt plates are fixed with bonding agent respectively in four edges at plank, and the thickness of edge butt plate is identical with the distance between described sound-absorbing slab adjacent peaks and trough,
Coating adhesive on sound-absorbing slab crest separately and on four edge butt plates, described bonding agent is modified epoxy glue.
The second plank is covered on sound-absorbing slab, and fixing, and four edges of described the second plank just in time cover four edge butt plates.
The thickness of described the first plank and the second plank is 3mm.
The production method of abatvoix of the present invention, by the mixed material that spray epoxy powder and bast fiber are made on wavy wire gauze, make to wrap up on wire gauze the bast fiber that one deck is fluffy, above-mentioned wire gauze is fixed in the middle of sheet material, both attractive in appearance, reached again extraordinary sound-absorbing effect, and cost is low.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
