Abstract
The utility model discloses sound insulation glass, in particular to vibration absorption, decoupling and sound insulation glass, which belongs to the field of noise and vibration control and is formed by sheet glass and vibration absorption and sound insulation films. Resonance phenomena amplitudes caused when sound waves transmit in the sound insulation glass are reduced by adjusting and controlling thickness density and vibration coefficients of the sheet glass. The sheet glass with different vibration coefficients can be adhered through vibration absorption and sound insulation films by utilizing characteristics of sound waves transmitting in media to enable produced vibration of conduction of the sound waves to interfere with each other. Produced vibration power energy can be absorbed by the vibration absorption and sound insulation films and converted into heat energy to conduct and diffuse. Accordingly, the sound insulation index of the sound insulation glass is greatly improved. The vibration absorption, decoupling and sound insulation glass can be widely applied to treatment fields of environment noises and traffic noises existing in daily life and has great social benefits and economic benefits.
Description
Affiliated technical field
The utility model relates to a kind of sound control glass, and especially a kind of vibration damping sound control glass of decoupling belongs to noise and vibration control field.
Technical background
When sound wave is propagated in medium, can make the object with identical vibration coefficient produce resonance, this resonance effect has weakened the iris action of object to sound wave, has played the strengthening effect that sound wave propagate is added fuel to the flames to a certain extent.Two closely adjacent mutually objects with different vibration coefficients; The vibration that under same frequency acoustic vibration, can produce different frequency; Object with different vibrational frequencies interferes with each other vibration each other because both are closely adjacent, our decoupling of being referred to as to vibrate of this interferential process.The sound control glass that the same former sheet glass density of principle thickness is identical produces resonance to certain frequency in parallel face decline to a great extent sound-damping qualities, even less than the sound-damping qualities of same thickness single-glass, our coupling that is referred to as to vibrate of this phenomenon.So we can adjust the density of original sheet glass and the order of thickness and placement when making sound control glass, come at utmost to reduce the resonance that sound wave produces between former sheet glass.The glass of different levels is because vibrative energy rank is different simultaneously, and the vibration of itself can weaken whole vibration under interfering with each other, and makes sound control glass integral body trend towards keeping a metastable state.
Summary of the invention
The purpose of the utility model is: through the vibration damping acoustic mastic sheet material of placing between former sheet glass material chosen and the former sheet glass is transformed adjustment; Make adjacent former sheet glass in the sound wave propagate process, produce the vibration of different wave length frequency, and then reach the ideal soundproof effect through the absorption of vibration damping sound insulation film and the vibration interference consumption between the former sheet glass.
The purpose of the utility model is achieved in that selects at least two former sheet glass with different vibration coefficients for use when making sound control glass described in the utility model, wherein the glass of minimum thickness selects for use density between 2.20-2.23g/cm
3Former sheet glass, the glass of maximum ga(u)ge selects for use density greater than 2.28g/cm
3Former sheet glass, the glass of all the other thickness selects for use density between 2.24-2.27g/cm
3Original sheet glass, the thickness difference between the adjacent former sheet glass should be greater than 0.5mm, density difference should be greater than 0.01g/cm
3The dimensions of required former sheet glass is cut into identical size, and so the purpose of operation is the vibration coefficient adjustment between each former sheet glass within the different range.Then former sheet glass is placed according to the big principle of the little thickness of the inboard density big thickness of little outside density in order, between adjacent former, placed the vibration damping sound insulation film of processing by the EVA material, adopt the mode of heating and pressurizing to process.
The advantage of the utility model is: reduce between resonance generation, absorbed oscillation energy, medium the several aspects of vibration interference from the vibration coefficient of adjustment glass and set about simultaneously; Acoustic vibration route of transmission in glass can be effectively controlled, thereby obtain outstanding soundproof effect.
Compare double glazing, the vibration interference phenomenon that produces when each other processing mode glued together can more effectively utilize sound wave propagate between the glass also helps the vibration that vibration damping sound insulation film absorbs sound wave.
Compare common PVB laminated glass, the vibration damping sound insulation film of EVA material has better low temperature elasticity and damping effect, and the sound-proofing properties of sound control glass is not acted upon by temperature changes, and the energy that can rapidly vibration interference be produced changes heat into and conducts.
Compare the working method of PVB doubling glass and perfusion glue, it is simple to produce the vibration damping processing units that sound control glass uses of decoupling, and yield rate is high, and is effective, cheap for manufacturing cost, low to energy degree of dependence.
Description of drawings
Fig. 1 is the schematic cross-section of a kind of embodiment of the utility model
Among the figure 1, the former sheet glass of the former sheet glass of the former sheet glass of the first layer 2, the second layer 3, the 3rd layer 4, the first layer vibration damping sound insulation film 5, second layer vibration damping sound insulation film
Embodiment:
Below in conjunction with embodiment accompanying drawing and the utility model are described further.
Visible by Fig. 1; We select the former sheet glass of three different thickness for use and the 3rd layer of former sheet glass 3 of the former sheet glass of the second layer of the former sheet glass of former the first layer that is divided into 3mm 1,4mm 2,5mm are controlled the thickness of former sheet glass when making the said sound control glass of the utility model, and wherein former sheet glass 1 density of the first layer is 2.22g/cm
3, former sheet glass 2 density of the second layer are 2.25g/cm
3, the 3rd layer of former sheet glass 3 density are 2.29g/cm
3Then these three former sheet glass are cut into identical specification, so just the vibration coefficient adjustment between three former sheet glass has been arrived within the different range.Then three sheet glass are respectively the series arrangement of 3mm, 4mm, 5mm according to thickness from the inside to the outside; Between 3mm glass and 4mm glass, place the first layer vibration damping sound insulation film 4; Place second layer vibration damping sound insulation film 5 between 4mm glass and the 5mm glass; After accomplishing above-mentioned operation, carry out the interlayer processing treatment with closing the glass that sheet accomplishes with the vacuum single stage method, the described vibration damping that disposes the afterwards sound control glass of decoupling promptly completes.
In the present embodiment, the vibration damping sound deadening sheet adopts the EVA material to process, and processing units adopts vacuum single stage method glass doubling stove, the use temperature of present embodiment be-58 ℃ to 90 ℃, through measuring, the comprehensive sound-damping qualities of present embodiment is 47dB.
