Abstract

In bonding the surfaces of 2 components or materials by a foil, a hardenable polymethacrylate bead polymer (in example PMMA) in Me methacrylate monomer is introduced between the parts to be bonded. Polymer: monomer mixing ratio is such that the mixt. gels by dissolving the beads and can be cast, extruded or spread to form a thin layer, esp. a foil (1). This layer of foil is placed between the surfaces to be bonded and hardened. The foil is used esp. for bonding polymethacrylate parts. or for bonding a polymethacrylate pt. to a cellulose acetate-butyrate component pt. Pref. the foil is an intermediate layer for coating a cellulose acrylate-butyrate foil, esp. an optical filter- or blind foil, on one or both sides, with polymethacrylate sheets or foil. The reactive layer of foil forms a permanent bond having accurate, uniform thickness. The optical quality of the pts. to be bonded is unimpaired. The foil resists yellowing and weathering.

Description

Verfahren zum Verbinden von zwei Teilen durch eine Folie Method of connecting two parts with a foil

Die Erfindung betrifft ein Verfahren zum flächigen Verbinden von Oberflächen zweier Teile oder Stoffe miteinander durch eine Folie.The invention relates to a method for the planar joining of surfaces two parts or substances together through a film.

Es sind zweiseitig haftende Klebfolien bekannt, durch die zwei Teile flächig miteinander verbunden werden können.There are double-sided adhesive films known, through the two parts can be connected to one another over a large area.

Die Haftdauer dieser bekannten Klebfolien ist begrenzt, und ein blasenfreies Aufbringen gestaltet sich als schwierig. Bei durchsichtigen Materialien verschlechtert die Folie und deren klebende Schichten die optische Qualität.The duration of adhesion of these known adhesive films is limited and bubble-free Applying turns out to be difficult. Deteriorated with transparent materials the film and its adhesive layers improve the optical quality.

Ferner sind diese Folien meist nicht vergilbungsfest und witterungsbeständig.Furthermore, these films are usually not resistant to yellowing and weathering.

Aufgabe der Erfindung ist es, ein Verfahren der eingangs genannten Art derart zu verbessern, daß eine dauerhafte, zerstörungsfreie und optisch einwandfreie Verbindung. zwischen den Teilen oder Stoffen entsteht.The object of the invention is to provide a method of the type mentioned at the beginning Kind to improve in such a way that a permanent, non-destructive and optically flawless Link. arises between the parts or fabrics.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Perlpolymerisat eines härtbaren Polymethacrylats in monomerem härtbarem Methacryl(säuremethyl)ester in einem derartigen Mischungsverhältnis eingebracht wird, daß diese Mischung durch Anlösen der Perlen geliert und zu einer dünnen Schicht, insbesondere eine Folie gießbar, extrudierbar oder streichbar ist, und daß diese Schicht oder Folie zwischen die zu verbindenden Oberflächen gelegt und ausgehärtet wird.This object is achieved according to the invention in that a bead polymer of a curable polymethacrylate in monomeric curable methacrylic (acid methyl) ester is introduced in such a mixing ratio that this mixture by dissolving the pearls and gelled into a thin layer, especially one The film is castable, extrudable or paintable, and that this layer or film is placed between the surfaces to be connected and cured.

Durch das erfindungsgemäße Verfahren wird eine reaktionsfähige, polymerisationsfähige Verbindungsfolie exakter, einheitlicher Stärke bzw. Dicke geschaffen, die eine genaue Distanzierung-der zu verbindenden Teile und Stoffe erlaubt und die optische Qualität der zu verbindenden Teile nicht verschlechtert. Die Folie bleibt vergilbungsfest und witteru-ngsbeständig. Die Folie ist reaktionsfähig und kann Teile oder Folien aus Polymethacrylat und/ oder aus Zelluloseacetatbutyrat anlösen, so daß eine chemische Verbindung entsteht. Dabei geschieht das Anlösen nicht so stark, daß eine Beschädigung der Teile oder Stoffe entsteht. Vielmehr entsteht nach der Aushärtung der Folie eine einheitliche Folie mit den anderen Teilen, Stoffen oder Folien, so daß die Verbindung unlösbar ist.The inventive method is a reactive, polymerizable Connection film of exact, uniform strength or thickness created that an exact Distancing the parts and fabrics to be connected is allowed and the optical quality of the parts to be connected does not deteriorate. The film remains resistant to yellowing and weatherproof. The foil is reactive and can be parts or foils from polymethacrylate and / or from cellulose acetate butyrate, so that a chemical Connection is established. The loosening is not so strong that it is damaged the parts or substances are created. Rather, it arises after the film has cured a uniform film with the other parts, fabrics or films, so that the Connection is indissoluble.

Die erfindungsgemäße Verbindungsfolie ist gummiartig und von ausreichender Eigenstabilität, so daß sie leicht verarbeitbar, insbesondere schneidbar oder stanzbar ist.The connecting film according to the invention is rubber-like and of sufficient quality Intrinsic stability, so that they can be easily processed, in particular cut or punched is.

Die Eigenstabilität wird durch das Mischungsverhältnis bestimmt. Hierzu wird vorzugsweise vorgeschlagen, daß 40 bis 70 , vorzugsweise 60 Gewichtsprozente Perlpoly merisat in 40 bis 70 , #orzugsweise 40 Gewichtsprozente Methacryl.{säuremethyl) ester gemischt werden.The inherent stability is determined by the mixing ratio. For this it is preferably suggested that 40 to 70, preferably 60 percent by weight Pearl polymer in 40 to 70, # preferably 40 percent by weight methacrylic. {Acid methyl) esters can be mixed.

Die Folie kann vorteilhaft zur Verbindung von Teilen aus Polymethacrylat verwendet werden, da sie dann nach dem Erhärten in diese übergeht.The film can advantageously be used to connect parts made of polymethacrylate should be used, as it then merges into this after hardening.

Besonders vorteilhaft ist es auch, wenn die Folie zur Verbindung von einem Teil aus Polymethacrylat und einem zweiten Teil aus Celluloseacetatbutyrat verwendet wird.It is also particularly advantageous if the film is used to connect a part made of polymethacrylate and a second part made of cellulose acetate butyrate is used.

In diesem Fall ist die Folie besonders vorteilhaft zum Schutz und zur Verstärkung von Filterfolien einsetzbar.In this case, the film is particularly advantageous for protection and Can be used to reinforce filter foils.

Dabei kann die Folie eine Zwischenlage sein zur ein-oder zweiseitigen Beschichtung von einer Celluloseacetatbutyratfolie, insbesondere einer Filterfolie wie einer Jalousiefolie durch Polymethacrylatplatte(n) oder -folie(n).The film can be an intermediate layer on one or two sides Coating of a cellulose acetate butyrate film, in particular a filter film like a blind foil through polymethacrylate plate (s) or foil (s).

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung in Schnitt dargestellt und werden im folgenden näher beschrieben. Es zeigen: Fig. 1 eine Verbindungsfolie zwischen einer zu schützenden zweiten Folie und einer Abdeckplatte und Fig. 2 eine zu schützende zweite Folie zwischen zwei Verbindungsfolien und daran auf beiden Seiten anliegende Abdeckplatten.Two exemplary embodiments of the invention are shown in section in the drawing and are described in more detail below. They show: FIG. 1 a connecting film between a second film to be protected and a cover plate and FIG. 2 a second film to be protected between two connecting films and on both of them Cover plates close to the sides.

Zur Schaffung der Verbindungs- oder Klebe folie 1 wird perlförmiges Polymethacrylat (Polymethacrylsäuremethylester) in monomeren Methacrylsäuremethylester in einem Mischungsverhältnis von 7 zu 3 bis 3 zu 7, vorzugsweise 6 zu 4 eingerührt. Diese Mischung geliert und wird zu einer dünnen Schicht, insbesondere einer Folie, gegossen oder aber durch einen Rakel gestrichen. Nachdem eine gummiartig elastische Folie oder Schicht von ca. 0,5 mm Stn entstanden ist, wird diese auf das zu schützende Objekt, in diesem Fall auf eine optische Filterfolie 2 aus Celluloseacetatbutyrat von ca. 0,7 mm Dicke gelegt.To create the connection or adhesive film 1 is bead-shaped Polymethacrylate (polymethacrylic acid methyl ester) in monomeric methacrylic acid methyl ester stirred in in a mixing ratio of 7 to 3 to 3 to 7, preferably 6 to 4. This mixture gels and becomes a thin layer, especially a film, poured or painted with a squeegee. Having a rubbery elastic Foil or layer of approx. 0.5 mm stn has been created, this is applied to the area to be protected Object, in this case on an optical filter film 2 made of cellulose acetate butyrate 0.7 mm thick.

Danach wird auf die Verbindungsfolie 1 eine Abdeckplatte 3 aus Polymethacrylsäuremethylester von ca. 2 bis 3 mm Stärke gelegt.A cover plate 3 made of methyl polymethacrylate is then placed on the connecting film 1 about 2 to 3 mm thick.

Die Verbindungsfolie 1 löst die Oberseite der Folie 2 und die Unterseite der Abdeckplatte begrenzt an, wobei der Grad des Anlösens durch den Anteil des Monomeren an der Verbindungsfolie 1 gewählt werden kann. Durch Energiezufuhr, insbesondere durch Erwärmung, polymerisiert dann die Verbindungsfolie 1, deren Monomer Härter und Initiatoren enthält. Besonders vorteilhaft ist es, wenn die Verbindungsfolie 1 bzw. die dünne Schicht durch UV-Strahlung ausgehärtet wird, da dann ein schädliches Erwärmen der anderen Schichten vermieden werden kann. Hierzu weist die Folie oder Schicht einen Fotokatalysator auf. Alternativ können aber auch andere energiereiche Strahlungen verwendet werden.The connecting foil 1 releases the top of the foil 2 and the underside the cover plate is limited, the degree of dissolution by the proportion of the monomer can be selected on the connecting film 1. By supplying energy, in particular by heating, the connecting film 1, the monomer of which is hardener, then polymerizes and initiators. It is particularly advantageous if the connecting film 1 or the thin layer is cured by UV radiation, since then a harmful Heating the other layers can be avoided. For this purpose, the film or Layer on a photocatalyst. Alternatively, however, other high-energy Radiations are used.

Das in Fig. 2 gezeigte Ausführungsbeispiel unterscheidet sich von dem in Fig 1 gezeigten nur dadurch, daß die zu schützende zweite Folie 2 an der Unterseite auch durch eine Abdeckplatte 3a geschützt ist, wobei wiederum zwischen 3a und 2 eine Verbindungsfolie la einliegt.The embodiment shown in Fig. 2 differs from that shown in Fig. 1 only in that the second film to be protected 2 on the Underside is also protected by a cover plate 3a, again between 3a and 2 a connecting film la is inserted.

Die Folie 1 oder Schicht kann auch vor der Verbindung eingefärbt werden, so daß die Folie oder Schicht die zusätzliche. Funktion erhält, den Teilen oder Stoffen eine Färbung zu geben. Dies ist z.B. ein besonders einfaches und preiswertes Verfahren, farbige Filterfolien zu erhalten.The film 1 or layer can also be colored before the connection, so that the foil or layer is the extra. Function, parts or To give fabrics a color. This is e.g. a particularly simple and inexpensive one Method of obtaining colored filter films.
