Contrast row two
With embodiment one, its difference is, in described laminated glass, PVB film includes a kind of PVB puigging, and this
PVB puigging is PVB puigging prepared by polyvinyl butyral resin.
Laminated glass embodiment one, two, three, four, five and comparative example one, comparative example two obtained uses the most general
Laboratory measurement, the sound transmission loss data recording laminated glass are as shown in table 1.
The sound transmission loss of each laminated glass of table 1
The sound transmission loss of embodiment one, two, three is more or less the same as can be seen from Table 1, and the sound transmission loss of embodiment four, five is more than
Embodiment one, two, three, this is owing in the PVB film of embodiment four, five, the puigging number of plies is big, improve laminated glass every
Volume.But the puigging number of plies is many, equipment investment is big, and manufacturing cost is high, and Comparatively speaking, 3 layers of puigging cost are controlled, can obtain again
To the PVB laminated glass that soundproof effect is good.Comparative example one and comparative example one, the sound transmission loss of embodiment one is more than comparative example
One, this is owing to adding nano silicon at polystyrene film, improve the sound insulation of laminated glass to a certain extent
Effect.Comparative example one and comparative example two, it appeared that the sound transmission loss of embodiment one compares the sound transmission loss of comparative example two nearly
Improve 20 db, this is owing to arranging at least two PVB puigging in PVB film, and includes a kind of by cross-linking PVB tree
Crosslinkable PVB puigging prepared by fat, by cross-linking the combination of the level different from the combination of non-crosslinked level or the degree of cross linking
It is greatly improved than the simple PVB film damping capacity using a kind of puigging.
Laminated glass embodiment one, two, three, four, five and comparative example one, comparative example two obtained uses GB9656-03
The laminated glass shock resistance experimental technique of regulation is tested, it is stipulated that the glass fragment peeled off from the negative after test is less than 15
Gram, the fragment of glass is the fewest, and the shock resistance of glass is the best.Test condition is: flakes weight during test under the conditions of-20 DEG C
Amount meansigma methods and 40 DEG C under the conditions of test time flakes weight meansigma methods, be highly set to 9 meters when-20 DEG C, when 40 DEG C
Highly it is set to 10 meters.
Table 2 each laminated glass thermal shock experimental result
From Table 2, it can be seen that the chip mass of comparative example two is much larger than by embodiment one, two, three, four, five and contrast
Example one, this is owing to introducing crosslinkable PVB puigging in laminated glass, considerably increasing the mechanical performance of laminated glass,
Impact strength is greatly enhanced, and the crosslinkable PVB the biggest intensity of the puigging number of plies is the highest, from embodiment four, five it can be seen that
There is not fragment in the laminated glass of seven layers of pvb film.
Laminated glass embodiment one, two, three, four, five and comparative example one, two obtained uses thermal shock test chamber to enter
Row thermal shock is tested, and circulates 1000 times, and range of temperature is 20-40 DEG C/min, and test result is as shown in table 3:
Table 3 each laminated glass thermal shock experimental result
From table 3 it is observed that embodiment one, two, three, four, five and comparative example two PVB glue after thermal shock is tested
Sheet is without coming off, and comparative example one is after testing through thermal shock, and PVB film comes off.This be due to PVB film the coefficient of expansion and
The coefficient of expansion of glass substrate is different, when ambient temperature acute variation, causes PVB film and glass substrate shrinkage degree
Inconsistent, gap occurs, even comes off.When arranging elastic cord breaker between PVB film and glass substrate, can well solve
This problem.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
