Description
Technical field
The utility model is related to a kind of PVB intermediate coats, among more particularly to a kind of function composite PVB containing damping characteristic
Film.
Background technology
Polyvinyl butyral（PVB）It is the condensation product of polyvinyl alcohol and butyraldehyde, PVB most important application fields at home
It is as intermediate coat and in laminated glass.PVB intermediate coats are squeezed by polyvinyl butyral resin through plasticizer plasticizing
A kind of high molecular material of type, not only appearance is semitransparent thin film for it, and free from admixture, surfacing, have certain roughness and
Good flexibility has unorganic glass good cohesive force, has the spies such as transparent, heat-resisting, cold-resistant, moisture-proof, mechanical strength height
Property, it is the optimum adhesion material that interlayer, safety glass are manufactured on our times.
The PVB intermediate coats of existing laminated glass-use are difficult to cope with flourishing traffic and densely populated caused noise is stranded
It disturbs, can not meet sound isolation requirement.Since noise is that vibration generates, glass is radiated by noise sound wave, and glass, which can generate, to shake
It is dynamic.If the vibration that glass cannot be inhibited to be generated by the radiation of sound wave, vibration can generate noise again.Based on the above situation, I
Department develops a kind of PVB intermediate coats with damping characteristic, to reduce the vibration of glass, and then reduces noise.
Utility model content
The purpose of this utility model is to provide a kind of function composite PVB intermediate coats containing damping characteristic, among this PVB
Film has the function of damping characteristic, to solve the problems, such as that glass sound insulation value is poor in the prior art.
The above-mentioned technical purpose of the utility model technical scheme is that：It is a kind of containing damping characteristic
Function composite PVB intermediate coats, including PVB upper stratas and PVB lower floors, the PVB upper stratas, PVB lower floors mutually glue with laminated glass
The side of knot is both provided with rough surface, and the glass layer of reticular structure, institute are provided between the PVB upper stratas and PVB lower floors
It states and is both provided with damping glue-line between PVB upper stratas, PVB lower floors and glass layer.
The utility model is further arranged to：The thickness that the glass layer is is 0.10-0.25mm, and glass fibre
The mesh aperture of layer is 0.8mm.
The utility model is further arranged to：The thickness of the PVB upper stratas and PVB lower floors is 0.30-0.35mm.
The utility model is further arranged to：The thickness of the damping glue-line is preferably 0.08mm.
The utility model is further arranged to：The rough surface is preferably corrugated surface, per pass ripple and neighboring track ripple
Between the angle that is formed be 90 degree.
In conclusion the utility model has the advantages that：
1st, by being provided with the glass layer of reticular structure between PVB upper stratas and PVB lower floors, due to glass fibre in itself
Elasticity and interfibrous compression and friction, with certain damping and elasticity, the radiation of extraneous sound wave can be inhaled
It receives, there is stronger sound-absorbing effect, it can utmostly sound energy consumption；
2nd, by being both provided with damping glue-line between PVB upper stratas, PVB lower floors and glass layer, due to damping glue-line tool
Flexible performance, according to damping harmony reflecting effect, damping glue-line has the effect of stronger isolation low frequency noise；
3rd, rough surface is both provided with by PVB upper stratas, PVB lower floors and the bonding side of laminated glass, sound wave with
Energy can cancel out each other when the rough surface of uneven shape is reflected, and so as to weaken the reflection of sound wave, make an uproar to avoid secondary
Sound pollution.
Description of the drawings
Fig. 1 is the longitudinal sectional view of embodiment.
Reference numeral：1st, PVB upper stratas；2nd, PVB lower floors；3rd, rough surface；4th, glass layer；5th, glue-line is damped.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model by Patent Law.
As shown in Figure 1, a kind of function composite PVB intermediate coats containing damping characteristic, including PVB upper stratas 1 and PVB lower floors
2.PVB upper stratas 1, PVB lower floors 2 and the bonding side of laminated glass are both provided with rough surface 3, and rough surface 3 is by frosted
Reason causes rough surface, and there is the PVB upper stratas 1 of certain roughness, PVB lower floors 2 can increase the contact surface between laminated glass
Product, and then increase its cohesive force.The glass layer 4 of reticular structure is provided between PVB upper stratas 1 and PVB lower floors 2, due to it
The presence of glass layer 4 and between PVB upper stratas 1 and PVB lower floors 2, can improve the integral strength of PVB intermediate coats.If folder
When layer glass occurs broken, due to the effect of the glass layer 4 of reticular structure, being scattered everywhere for glass fragment can be avoided to cause
The generation of injures and deaths.Simultaneously as the elastic and interfibrous compression and friction of glass fibre in itself, have certain damping and bullet
Property, the radiation of extraneous sound wave can be absorbed, there is stronger sound-absorbing effect, it also can utmostly sound energy consumption.
Damping glue-line 5 is both provided between PVB upper stratas 1, PVB lower floors 2 and glass layer 4, glue-line 5 is damped by setting
The fastness that glass layer 4 is bonded with PVB upper stratas 1, PVB lower floors 2 can be increased.Simultaneously as damping glue-line 5 has elasticity
Can, according to damping harmony reflecting effect, damping glue-line 5 has the effect of stronger isolation low frequency noise, comprehensive glass layer 4
And the cooperation of damping glue-line 5, it can reach the effect of the most of noise of the utility model isolation.
Due to using PVB intermediate coats laminated glass reflection it is stronger, sound wave enter in the cavity of laminated glass be also easy to produce it is mixed
It rings, quadratic noise to be caused to pollute.It is now placed in PVB upper stratas 1, the rough surface 3 of PVB lower floors 2 towards the side of laminated glass exists
When encountering sound wave, sound wave energy when the rough surface 3 with uneven shape is reflected can cancel out each other, so as to decrease sound
The reflection of wave is polluted to avoid quadratic noise.
The thickness that glass layer 4 in the present embodiment is is 0.10-0.25mm, and the mesh aperture of glass layer 4
For 0.8mm.
The thickness on PVB upper stratas 1 and PVB lower floors 2 in the present embodiment is 0.30-0.35mm.
The thickness of damping glue-line 5 in the present embodiment is preferably 0.08mm.
The preferably corrugated surface of rough surface 3 in the present embodiment, the folder formed between per pass ripple and neighboring track ripple
Angle is 90 degree.
