By puigging (B layers and the C of the multilaminar polyethylene acetal film prepared in the embodiment 1~3 and comparative example 1~5
Layer) in plasticizer loading, laminar structure, each layer of thickness and integral thickness be shown in table 1 below.
Experimental example：The evaluation of sound-proofing and resistance to penetrability
Prepare the folder engaged by the multilaminar polyethylene acetal film prepared in the embodiment 1~3 and comparative example 1~5
After layer glass, the sound-proofing of the laminated glass and resistance to penetrability are determined using following methods, and its result is shown in table 1
In.
The measure of sound-proofing
By 300mm × 25mm 2.1T glass and the plural layers of embodiment 1~3 and comparative example 1~5 with 2.1T glass-
The laminar structure of plural layers -2.1T glass on laminating machine is heated and pressurizeed with 130 DEG C of temperature 15 minutes and carried out
Engage and be prepared for test piece, and aging (aging) 1 hour in 0 DEG C, 20 DEG C or 30 DEG C of constant temperature chamber.
Applied using the vibration machine for damping test to the test piece and vibrated, and the vibration characteristics obtained is used
Mechanical impedance amplifier is amplified, and then utilizes Fast Fourier Transform (FFT) (FFT, fast Fourier transform) frequency spectrum
Analyzer is analyzed the rumble spectrum obtained and draws chart.Calculated according to the obtained chart and using 1dB methods
Loss factor near 2,000~4,000Hz frequencies.Loss factor is higher, and sound insulation value is more excellent, in general acoustic film
There is 0.35 loss factor at 20 DEG C.
The measure of resistance to penetrability
Laminated glass resistance to of the present utility model engaged by Polyvinyl acetal film is have rated according to KS L 2007 to pass through
Wearing property.Specifically, 300mm × 300mm 2.1T glass and the plural layers of embodiment 1~3 and comparative example 1~5, system are utilized
Standby laminar structure is the laminated glass of 2.1T glass-plural layers -2.1T glass, and is tentatively engaged with vacuum, so as to enter
Row degassing and edge sealing (edge sealing).Afterwards, formally connect at 150 DEG C using autoclave (autoclave)
Close 2 hours, so as to be prepared for engaging test piece.Afterwards, 2.26kg steel ball is dropped in the engagement test piece, so as to determine examination
Piece by through height (MBH).Now, when test piece by through height be less than 4m when, labeled as unqualified (fail), work as test piece
By through height be more than 4m when, labeled as qualified (pass).
The measure of impact resistance
According to KS L 2007:Whether 2008 to have rated the glass engaged by Polyvinyl acetal film jagged, it is specific and
Speech, using 300mm × 300mm 2.1T glass and the plural layers of embodiment 1~3 and comparative example 1~5, with 2.1T glass-more
The laminar structure of layer film -2.1T glass on laminating machine is heated and pressurizeed with 150 DEG C of temperature 15 minutes and connect
Close, so as to be prepared for test piece.Afterwards, the steel ball for the 227g that 4 hours are preserved at subzero 20 DEG C is highly dropped into engagement from 9m
In test piece, then the steel ball is preserved 4 hours at 40 DEG C again.Afterwards, the steel ball is made from the height away from engagement test piece 19m
Land on degree, when broken by the test piece impacted and the amount for the glass that glass disperses or dropped from thin slice occurs is 15g
During the above, labeled as unqualified (fail), when by the test piece impacted do not have it is broken or occur glass disperse and from thin slice
On the amount of glass that drops when being less than 15g, labeled as qualified (pass).
[table 1]
As shown in table 1, when the plasticizer loading of B layers and C layers differs more than 2 weight %, in 0~30 DEG C of wide temperature
In the range of excellent sound insulation value is shown relative to the plural layers of comparative example, and also show good resistance to penetrability.
Especially, the comparative example 4 that the plural layers for the embodiment 1~3 that the thickness of A layers is more than 0.06mm are 0.05mm with the thickness of A layers
Compare, such as resistance to penetrability physical property is undiminished simultaneously, also shows excellent sound insulation value.In addition, using A layers as
The plural layers of the embodiment 1~3 on the top layer of plural layers show excellent resistance to penetrability compared with comparative example 3.Further
Ground, in the case of the adjacent comparative example 5 of B layers and C layers, B layers is clipped in compared with the embodiment 1 between C layers with A layers, in low temperature
It is poor with the sound insulation value under high temperature.This is considered as because of caused by plasticizer movement between B layers and C layers.
