Hier setzt nun die vorliegende Erfindung ein. Sie hierzu zum Beispiel Vieweg/Müller, Kunststoffbesteht

sind, wobei Schichten aus amorphen Polyamiden zur darum, weil ein nachträgliches Lackieren der zwi-Erzielung

und unter Verwendung von weichmacherhaltigem freie Durchsicht nicht gewährleistet.
Polyvinylbutyral als Bindemittel diese Polyamid- Ein weiterer Vorteil der vorliegenden ErfindungThis is where the present invention comes in. For example, Vieweg / Müller, Kunststoff consists in a process for the production of through-60 manual "Polyamide", Volume VI, 1966, p. 425, but visible security laminate that, like composite, could be used from it with regard to the present invention, security or composite armored glass no conclusion can be drawn. This is especially true, with layers of amorphous polyamides for the reason that a subsequent painting of the intermediate achievement of a visually flawless surface see plane-parallel plates pressed polyamide individually pressed between plane-parallel plates 65 layers an absolutely refractive and deflecting and using plasticizer-free transparency not guaranteed.
Polyvinyl butyral as a binder this polyamide- Another advantage of the present invention

lieben Durchlaufveriahren erfolgen kann. Die Überzugsmaterialien, die in Form von härtenden Lacklösungen vorliegen, werden z. B. über eine Lackiervorrichtung auf die endlose Rohfolie aufgetragen und härten dann in einem nachgeschalteten Trockenkanal S aus.love continuous procedures can be done. The coating materials, which are in the form of hardening paint solutions, are z. B. applied via a painting device to the endless raw film and then harden in a downstream drying tunnel S.
Die Lacküberzüge haben auch die Aufgabe, eine Feuchtigkeitsdiffusion durch die amorphen Polyamide zu den weichgemachten Polyvinylbutyralschichten zu verhindern. Es ist bekannt, daß die Haftfestigkeit dieser Polyvinylbutyralschichten zu Silikatglas mit steigendem Feuchtigkeitsgehalt abnimmt. Dasselbe trifft für die Haftfestigkeit zu den amorphen Polyamiden zu. Aus diesem Grund ist ein Feuchtigkeitsgehalt in der Haftschicht von 0,05 bis 0,5% vorteil- haft, der über eine lange Lebensdauer der Verbundscheiben erhalten bleiben muß.The lacquer coatings also have the task of diffusing moisture through the amorphous polyamides to prevent plasticized polyvinyl butyral layers. It is known that the adhesive strength these polyvinyl butyral layers to silica glass decrease with increasing moisture content. The same thing applies to the adhesive strength to the amorphous polyamides. For this reason, a moisture content of 0.05 to 0.5% in the adhesive layer is advantageous. adhesive, which must be maintained over a long service life of the composite panes.
Im übrigen ist es zweckmäßig, auch die Seitenflächen der fertigen Verbundkörper zu lackieren, wobei es naturgemäß z. B. auf eine besondere Kratz- ao festigkeit des Lacküberzuges nicht unbedingt ankommt.In addition, it is useful to paint the side surfaces of the finished composite body as well, whereby it naturally z. B. a special scratch resistance of the paint coating is not necessarily important.
Ein Lackfilm, hergestellt aus 48 Gewichtsteilen »5 eines hydroxylgruppenhaltigen Polyesters aus Trimethylolpropan und Phthalsäureanhydrid (etwa 8% OH) und 52 Gewichtsteilen Hexamethylendiisocyanat — Biuret (etwa 22°/oNCO) wurde in einem Lösungsmittelgemisch aus Äthylglycolacetat, Methyläthylketon und Cyclohexanon auf die extrudierte Rohfolie eines amorphen Polyamids aufgetragen und 20 Minuten bei 120° C gehärtet Anschließend wurde die lackierte Folie zwischen planparallelen Platten abgepreßt. Es entstand eine optisch einwandfreie Folie, für den vorgesehenen Zweck. Derselbe Lack ist auch zur Abdichtung der Verbundglaskantea (Stirnflächen) geeignet. Er verhindert damit das Eindringen von Feuchtigkeit in das seitlich frei liegende weichgemachte Polyvinylbutyral. Solche eindringende 4» Feuchtigkeit kann zu Ablösungserscheinungen führen, die durch verminderte Haftung der Polyvinylbutyralfolie hervorgerufen werden.A paint film made from 48 parts by weight »5 of a hydroxyl-containing polyester made from trimethylolpropane and phthalic anhydride (approx 8% OH) and 52 parts by weight of hexamethylene diisocyanate - biuret (about 22% NCO) was in one Solvent mixture of ethyl glycol acetate, methyl ethyl ketone and cyclohexanone on the extruded Raw film of an amorphous polyamide was applied and cured at 120 ° C. for 20 minutes the coated film pressed between plane-parallel plates. The result was a visually flawless one Slide, for its intended purpose. The same varnish is also used to seal the laminated glass cantea (End faces) suitable. It prevents moisture from penetrating into the exposed side plasticized polyvinyl butyral. Such penetrating 4 » Moisture can lead to peeling phenomena, which are caused by reduced adhesion of the polyvinyl butyral film.

Auf eine Polyamidrohfolie wurde ein Lackfilm aus 70 Gewichtsteilen eines polyfunktionellen, hydroxylgruppenhaltigen Acrylathatzes und 30 Gewichtsteflen eines teilverätherten Melaminhaizes unter Verwendung eines Lösungsmittelgemisches aus Butvlacetat und Xylol aufgetragen. Nach Aushärtung bei 135° C während 30 Minuten und anschließendem Abpressen entstand eine optisch einwandfreie Folie.A lacquer film composed of 70 parts by weight of a polyfunctional, hydroxyl-containing acrylate and 30 parts by weight was applied to a raw polyamide film of a partially etherified melamine hair using a solvent mixture of butyl acetate and xylene applied. After curing at 135 ° C An optically perfect film was produced over 30 minutes, followed by pressing.
Die Haftfestigkeit wurde mit Hflfe der Gitterschnitt-Methode nach DIN 53 151 geprüft. Den Lacküberzügen gemäß Beispiel 1 und 2 konnte der Kennwert 1 zugeordnet werden. Beim Biegen der lackierten Polyamidfolie entstanden keine Risse und Abblätterungen.The adhesive strength was tested using the cross-cut method according to DIN 53 151. The The characteristic value 1 could be assigned to paint coatings according to Examples 1 and 2. When bending the lacquered polyamide film did not cause any cracks or flaking.
Die Wasserfestigkeit von gemäß der Erfindung hergestellten Verbundsicherheits- und Verbundpanzergläsern wurde nach dem bei Verbundglas üblichen Kochtest geprüft Hierbei wird nach DIN 52 304 Verbundglas 2 Stunden lang in kochendem Wasser gehalten, um festzustellen, inwieweit sich Blasen im Verbundglas bilden. Verbünde mit den genannten Polyamiden wurden ohne die schützenden Überzüge schon nach 20 Minuten milchig trübe und nach 2 Stunden vollkommen undurchsichtig. Durch die allseitig aufgebrachten Lacküberzüge nach Beispiel 1 uud 2 blieben hingegen die Proben nach diesem Kochtest klar durchsichtig.The water resistance of laminated safety glass and laminated armored glass produced according to the invention was determined by the standard for laminated glass Boiling test tested According to DIN 52 304, laminated glass is immersed in boiling water for 2 hours to see how much bubbles form in the laminated glass. Associations with the named Polyamides became milky and cloudy after just 20 minutes without the protective coatings 2 hours completely opaque. Due to the lacquer coatings applied on all sides according to Example 1 uud 2, however, the samples remained clear after this boiling test.
Die Kratzfestigkeit wurde nach der »Schaufelrad-Sand-Methode« und anschließender Messung der Tiübung nach DIN 53 490 bestimmt. Bei dieser Methode wirft ein rotierendes Schaufelrad periodisch Strahlsand (Korngröße 200 Mikron, Hauptanteil 60 bis 120 Mikron) gegen das zu prüfende Muster. Nach 6stündiger Einwirkung wird von den exponierten Platten im Vergleich zum unbehandelten Muster die Trübung ermitteltThe scratch resistance was determined using the “paddle wheel sand method” and subsequent measurement of the Ti exercise determined according to DIN 53 490. In this method, a rotating paddle wheel throws periodically Blasting sand (grain size 200 microns, main proportion 60 to 120 microns) against the sample to be tested. To 6 hours of exposure are the exposed panels compared to the untreated sample Turbidity determined
