Abstract
The present invention relates to comprise the film laminates with damping capacity of the sublayer being made up of polyvinyl alcohol contracting (different) aldehyde of plasticizer-containing.Specifically, the present invention relates to a kind of film laminates, become with C-shaped with layer A, B of at least one Pioloform, polyvinyl acetal by each at least one plasticizer self-contained of at least three, two of which outer layer A and C comprises the identical or different Pioloform, polyvinyl acetal of at least one PVA-based ratio with 18.5 to 23 weight %, at least one inner layer B comprises the Pioloform, polyvinyl acetal of the PVA-based ratio with 12 to 18 weight %, and at least one of layer A, B or C comprises at least one polyvinyl alcohol contracting (different) aldehyde.This film laminates may be used for manufacturing for automobile, aircraft, boats and ships, architectural glazings, the glass film layered product/glass composite of facade parts, or is used for manufacturing photovoltaic module.
Description
Technical field
The present invention relates to one be such as suitable as in composite safe glass (Verbundsicherheitsgl ser)
The film laminates in intermediate layer, described film laminates is by least three polyvinyl alcohol based on plasticizer-containing contracting (just) aldehyde
The layer of (Polyvinyl (n) acetal) and/or polyvinyl alcohol contracting (different) aldehyde (Polyvinyl (iso) acetal) is formed and to sound
The damping capacity that sound has had.
The present invention relates to the film laminates in a kind of intermediate layer being such as suitable as in composite safe glass, described film is laminated
Body is formed by the layer of at least three polyvinyl alcohol based on plasticizer-containing contracting (just) aldehyde and/or polyvinyl alcohol contracting (different) aldehyde and is had
Excellent penetration performance (Penetrationseigenschaft).
Prior art
Composite safe glass is generally made up of the intermediate coat of two glass plates and connection glass plate.Mainly make as membrane material
With the polyvinyl butyral resin (PVB) of plasticizer-containing, it can react acquisition by making polyvinyl alcohol and hutanal.
The feature become more and more important of compound window glass is its sound insulation value, and it can be adjusted by corresponding interlayer film
Joint.
To this end, the commonly used intermediate coat with 2 to 5 sublayers, the most each sublayer has difference in terms of its mechanical strength,
And realize sound insulation from there through mechanical decoupled conjunction.
Can such as by PVA-based in the plasticizer loading of described film or the Pioloform, polyvinyl acetal of use or
The ratio of polyvinyl acetate ester group, sets the different mechanical strengths of the film of Pioloform, polyvinyl acetal based on plasticizer-containing.
Generally, the mechanical strength of PVB film can be passed through in its plasticizer loading, or the Pioloform, polyvinyl acetal by use
Polyvinyl alcohol group or the ratio of polyvinyl acetate ester group regulated.
Such as, therefore US 5,340,654 or WO 2006/102049 describes multilayer system, and wherein ground floor comprises and has
The polyvinyl butyral resin of high residue acetate content, the second layer comprises the polyvinyl alcohol contracting fourth with low-residual acetate content
Aldehyde.
Similarly, WO 2008/137367 describes multilayer system, the sublayer being wherein made up of polyvinyl butyral resin
(Teilschicht) different in terms of polyvinyl alcohol content.
Due to different residual acetate content and/or different polyvinyl alcohol group ratios, each sublayer has different
Plasticizer loading, and therefore there is different mechanical strengths.It is achieved in mechanical decoupled conjunction and the sound insulation therefore improved.
Known multilayer film is based on the polyvinyl butyral resin that can obtain by making polyvinyl alcohol and hutanal react.Use
There is polyvinyl alcohol contracting (just) butyraldehyde of different polyvinyl alcohol or polyvinyl acetate contents, it is thus achieved that the different plasticizer of each layer
Content.The mechanical performance so causing each layer is different, and these differences are the biggest, and the sound insulation of layered product is the best.Excellent sound insulation is usual
Cause the mechanical performance of difference.Additionally, each layer is incompatible, there's almost no mechanical adhesion the most betwixt, and may be each other
Relatively slide.Incompatible each layer no longer can be mixed with each other, and therefore these film laminates can only be recycled in technique with differing from.
Therefore the purpose of the present invention is the film laminates manufacturing and having sound insulation value, due to gathering the plasticizer-containing used
Vinyl acetal is selected, and described film has high plasticizer compatbility and therefore shows excellent sound insulation.
Have now unexpectedly been found that the film laminates comprising at least one layer based on polyvinyl alcohol contracting (different) aldehyde has excellent
Plasticizer compatbility and owing to different mechanical strengths has excellent damping capacity.

Table 2 shows the physical data about film.Its display is compared with the comparative example with the PVA content that may compare, originally
The film of invention has preferably damping at 20 DEG C.The PVA content of the Pioloform, polyvinyl acetal used is certainly for the damping capacity of film
Qualitatively.Compared with the film with low PVA content, based on identical MW content, there is the film of high PVA content to fixed temperature
Poor damping is generally shown under (being 20 DEG C in this case).But in embodiment 3 and 4, contain even having high PVA
Amount, the film of the present invention still shows good damping capacity at 20 DEG C.This point is the plasticizer phase due to inventive film
Capacitive improve, damping maximum can towards lower temperature elapse the fact.Higher plasticizer absorption generally means that the machine of film
Tool performance, such as tearing strength are impaired.But, it has now been found that compared with the comparative example 1 and 2 with similar PVA content, implement
The film of the present invention in example 1 and 2 has even preferably tearing strength.
