Description
Technical field
The invention belongs to Building Decoration Material field more particularly to a kind of indoor decoration plate and its processing technologys.
Background technique
Now, with the continuous acceleration of urbanization, ambient noise problem influences people's lives, work increasingly severely
Make and learn, same air pollution, water pollution become one of social three big public hazards together for it.In order to effectively separate noise,
Common settling mode is using acoustic material.Existing acoustic material is generally cement concrete, glass plate etc., these sound insulations
The soundproof effect of material is not fine, therefore common solution is the thickness for increasing acoustic material.It is asked caused by this way
Topic is that acoustic material quality is overweight, and cost is excessively high, and installation process is inconvenient.
The patent of invention of 104861413 B of Authorization Notice No. CN discloses a kind of decoration interior sound insulation material, the sound insulation material
Material is made from the following raw materials in parts by weight: thermoplastic phenol resin 42-56, expanded vermiculite 20-25, polystyrene foam plastics 4-
6, silane coupling agent 2-3, nano carbon black 1-1.5, polymethyl methacrylate 8-10, antioxidant 0.1-0.2, foaming agent 0.1-
0.2, magnesite 0.2-0.3, solid content be 10-15% silicon dioxide gel 2-3,100-200 mesh montmorillonite 20-24, contain admittedly
Amount is aqueous polyurethane emulsion 10-12, the collagenous fibres 10-20 of 8-10%；Waste wool felt 20-30；Auxiliary agent 2-5.It is prepared
Expanded vermiculite-polyurethane multiple emulsion coating thermoplastic phenolic resin nonwoven acoustic insulator quality of materials is light, and thickness is small, soundproof effect
It is very good, it has good market prospects.The acoustic material has adhered to the advantages of conventional polypropylene non-woven material, and its mechanics
Performance is improved, and has excellent weatherable, and for a long time using indeformable, and the polyurethane multiple emulsion prepared is in fibre
After dimension table bread covers solidification, the material of doping improves fibre web intensity, and damping is reinforced, and effect of vibration and noise reduction is obvious, but
It is that the acoustic material only has good obstruction effect to the sound wave of high frequency, cannot achieve the efficient absorption of wide-band noise.
Summary of the invention
The present invention in order to solve the problems, such as decorating board to wide-band noise efficient absorption, provide a kind of indoor decoration plate and its
Processing technology.
In order to achieve the above object, base case of the invention provides a kind of indoor decoration plate, thermoplastic styrene resin
40-55 parts, 20-25 parts of expanded graphite, 2-3 parts of silane coupling agent, 18-30 parts of nitrile rubber, aqueous polyurethane emulsion 10-12,

The expanded graphite is after grinding graphite flake through 150-250 times of shape of 800-1000 DEG C of high-temperature roasting enlarged volume
At particulate matter.
The principle of this base case is: nitrile rubber is the atactic polymer as made from butadiene and acrylonitrile polymerization,
Itrile group containing polarized on molecule has the excellent properties such as heat-proof aging, can use for a long time in 120 DEG C of air；In addition, fourth
Nitrile rubber is also used as sound-absorbing material, is since nitrile rubber has viscoplasticity, when sound wave applies a week to nitrile rubber
When phase property external force, due to the relaxation of nitrile rubber strand, strain is caused to lag behind the hysteresis effect of stress, generate energy
Loss, and then the sound wave under different frequency is reduced；Expanded graphite can moment volume expansion 150 in heated reach at 1000 DEG C
~300 times, porous and be bent so that intumesced graphite structure is loose, expanded surface area, surface can improve, by expanded graphite
Being added in nitrile rubber can be used as bubble filler, and the velocity of sound in material can be made to be remarkably decreased, and attenuation constant obviously increases,
Improve the low frequency absorption performance of nitrile rubber, increases sound absorption frequency range；Fabric is a kind of fusiform cell, and inside has long and narrow
Cell, by fabric and nitrile rubber sample carry out layer and, sound wave is converted by interface layer and butyronitrile rubber
Multiple reflections between absorption inside glue and nitrile rubber fabric improve the consume of sound wave, and can prepare preferably reduces noise
Material.
The beneficial effect of this base case is: 1, nitrile rubber has viscoplasticity, and sound wave applies the period to nitrile rubber
Property external force when, the relaxation of nitrile rubber strand can cause the strain of sound wave to lag behind the hysteresis effect of stress, generate energy
Amount loss, and then the sound wave under different frequency is reduced；2, by being 150-250 times of volume expansion by expanded graphite high-temperature roasting
Graphite particle object be clipped in nitrile rubber, since the graphite of expansion is a kind of porous bubble filler of short texture, so that making an uproar
When sound passes through the decorating board of nitrile rubber material, the velocity of sound in decorating board declines, so that nitrile rubber has low frequency absorption performance,
The frequency absorption range to noise is widened；3, by expanded graphite layer middle layer and fabric, the middle ghost of fabric
Chamber enables to noise sound wave multiple reflections in nitrile rubber, improves the consume of sound wave, enables nitrile rubber fabric right
Wide-band noise efficient absorption.
