Definitions
- the invention relates to the use of a film with anchoring elements for mechanically attaching a coherent layer to a substrate.
- DE 7029524 describes a device for fastening wall, ceiling, floor or other surface cladding, which consists of an intermediate support with anchoring elements and a nonwoven on which non-fibrous cladding materials are fastened, e.g. Paper, plastic films, molded plastic parts, wood and metals.
- This device has the great advantage that the bonds can be loosened easily and without residue at a certain point.
- it has the disadvantage that it is very difficult to correct the position of the connected substrates relative to one another. This applies particularly to large-area substrates.
- cladding that compensates for unevenness is not possible.
- the invention relates to the use of a film with excellent and / or embedded anchoring elements for mechanically attaching a coherent layer to a substrate, the coherent layer not being fibrous.
- the preferred embodiments can be found in the characterizing features of the subclaims.
- the invention also relates to a double-sided adhesive tape made from a film with anchoring elements on at least one side instead of an otherwise usual smooth film, a woven fabric or a nonwoven, the adhesion of the pressure-sensitive layer of the film on one side of the film being so low that it becomes can be removed non-destructively.
- Another object of the invention is a film with embedded anchoring elements.
- Another object of the invention is a Velcro tape made of elastomers, in particular thermoplastic elastomers.
- Foils are thin, flat, flexible webs made of metals, glass, ceramics and especially plastics. Their thickness is advantageously in the range from 0.04 to 2 mm. But it can also go much further if it does not depend on the flexibility and easy winding of the webs arrives. In particular, molded parts come into question here, which are already provided with anchoring elements during manufacture, for example plates or strips.
- the surface of the film is appropriate, in particular it can be round or strip-shaped with a width of 0.2 to 1,000, in particular from 1 to 500 cm, with a length of 0.05 to 5,000, in particular from 0.1 to 4,000 m.
- the film is usually predominantly full-surface, i.e. it has no or only small pores or holes. The sum of the holes makes up at most 10% of the total area.
- the shape, size and number of holes should, if possible, be such that a desired gas or vapor permeability is achieved, but as far as possible nothing of the still liquid phase penetrates during the production of the coherent layer.
- the material of the film is either metal or plastic, preferably plastic, in particular polyolefins such as polyethylene and polypropylene, polyamide, polyvinyl chloride, fluorine-containing polymers, silicone or polyurethane elastomers or articles of daily use coated with them.
- the foils and anchoring elements are made of the same material. However, they can also consist of a combination of materials.
- the formability and adhesion of the non-fibrous coherent layer must be taken into account: the adhesion should be as low as possible and the formability of the anchoring elements and / or the non-fibrous coherent layer should be so great that the anchoring elements when separating the Layers are mostly not functional or even torn off.
- the low adhesion between the film and the non-fibrous coherent layer can result from the type of materials used. However, it can also be obtained by pretreatment before application of the liquid non-fibrous layer, e.g. by spraying with water or by coating with wax or similar substances that are difficult to bond.
- the formability of the anchoring elements or the coherent non-fibrous layer can likewise result from the type of materials used or can be caused by physical measures, for example by porosity.
- the shape of the anchoring elements also plays a role. If, for example, the non-fibrous coherent layer consists of a barely deformable material such as cement or gypsum-based binder or a 2-component epoxy, the anchoring elements in the material and shape should be relatively easily deformable and elastic, e.g. made of plastics such as PE, PP , Silicone or rubber.
- One side of the film is usually smooth so that it can be easily attached to the surface with a covered layer of adhesive or with nails and screws. However, it can also contain anchoring elements on both sides, particularly if the substrate is fibrous or if the same adhesive is to be used both for attaching the film to the substrate and for attaching to the substrate.
- the number of anchoring elements depends, among other things, on the desired level of liability. It is generally in the range from 0.1 to 2,000, preferably from 1 to 500 per cm 2 .
- the film has anchoring elements on at least one side.
- Their length is at least 0.05, preferably at least 0.2 mm.
- Length rarely exceeds 10 mm.
- the anchoring elements can be embedded in the film, but they preferably protrude beyond the film plane. In the latter case, it can be typical Velcro tapes, anti-slip tapes or stubble films, e.g. around flocked
- Velcro straps can be used equally well. So are anchoring elements with
- the cross-sectional diameter of the mushroom roof should be less than 10 times the value of the
- Anchoring elements with loops are of course special unfavorable (see Fig. 2).
- the forms of the anchoring elements are favorable if they allow them to slide out of the coherent layer without being inoperative or even torn off (see FIG. 3). Shapes are particularly favorable if the angle between the pin and the hook is 90 ° or greater (see FIG. 4). However, it must be less than 180 °, otherwise there will be no hooking, unless the pin is not perpendicular to the film, but at an angle. If the pins still point in different directions, they also anchor the non-fibrous coherent layer.
- the anchoring elements or their pins can also form an angle of less than 90 ° to the film, preferably an angle of less than 45 °. Which angle is the most favorable depends, among other things, on the deformability of the coherent layer.
- the ends of the anchoring elements are not pin-shaped but rather thickened (heads), angled or bent (hooks) or flattened (mushroom shape).
- 1a, 1b and 1c schematically show the change in the cross-sectional shape of an easily deformable anchoring element (1), a) during the first coating with the coherent layer, b) during its detachment in the hardened state and c) before the second coating.
- the mushroom head is deformed when detached.

Abstract
The invention relates to the use of a film with anchoring elements for a mechanic fixation. The projecting and/or embedded anchoring elements on at least one face of a film are used to mechanically fasten a coherent non-fibrous layer in order to establish a connection that can be easily and specifically detached. If an adhesive is used for the coherent non-fibrous layer, its adhesion to the film should be as small as possible. The coherent non-fibrous layer is produced by curing a more or less liquid layer.
Description
„Verwendung einer Folie mit Verankerungselementen zur mechanischen Befestigung""Use of a film with anchoring elements for mechanical fastening"
Die Erfindung betrifft die Verwendung einer Folie mit Verankerungselementen zur mechanischen Befestigung einer kohärenten Schicht mit einem Untergrund.The invention relates to the use of a film with anchoring elements for mechanically attaching a coherent layer to a substrate.
Eine derartige Verwendung ist bekannt. So wird in der DE 7029524 eine Vorrichtung zum Befestigen von Wand-, Decken-, Boden- oder anderen Oberflächenverkleidungen beschrieben, die aus einem Zwischenträger mit Verankerungselementen sowie aus einem Nonwoven besteht, auf dem nichtfaserige Verkleidungsmaterialien befestigt werden, z.B. Papier, Kunststoff- Folien, Kunststoff-Formteile, Holz und Metalle. Diese Vorrichtung hat den großen Vorteil, daß die Bindungen leicht und rückstandsfrei an einer bestimmten Stelle gelöst werden können. Sie hat jedoch den Nachteil, daß eine Korrektur der Position der verbundenen Substrate zueinander nur sehr schwer möglich ist. Das gilt insbesondere bei großflächigen Substraten. Außerdem ist eine Verkleidung nicht möglich, die Unebenheiten ausgleicht.Such use is known. DE 7029524 describes a device for fastening wall, ceiling, floor or other surface cladding, which consists of an intermediate support with anchoring elements and a nonwoven on which non-fibrous cladding materials are fastened, e.g. Paper, plastic films, molded plastic parts, wood and metals. This device has the great advantage that the bonds can be loosened easily and without residue at a certain point. However, it has the disadvantage that it is very difficult to correct the position of the connected substrates relative to one another. This applies particularly to large-area substrates. In addition, cladding that compensates for unevenness is not possible.
Daraus ergibt sich die Aufgabe, eine leicht lösbare Bindung von zwei Substraten zu finden, die diese Nachteile nicht hat und darüber hinaus einen Verbund ermöglicht, der den üblichen Zugscherbelastungen standhält, aber dennoch eine leichte und praktisch rückstandsfreie Trennung ermöglicht. Darüber hinaus sollte auch eine Wiederverwertung nach der Trennung möglich sein.This gives rise to the task of finding an easily detachable bond between two substrates which does not have these disadvantages and, moreover, enables a bond which withstands the usual tensile shear stresses, but nevertheless enables easy and practically residue-free separation. In addition, recycling should also be possible after separation.
Die erfindungsgemäße Lösung dieser Aufgabe ist den Patentansprüchen zu entnehmen. Sie besteht im wesentlichen darin, daß zur mechanischen Verankerung mit den Verankerungselementen einer Folie keine faserige Schicht verwendet wird.
Erfindungsgemäß wird ein flüssiger Stoff direkt auf die Folie mit den Verankerungselementen aufgetragen und dort verfestigt. Zwischen der Folie mit den Verankerungselementen und dem verfestigten flüssigen Stoff sollte eine möglichst geringe Adhäsion auftreten. Der Zusammenhalt sollte weitgehend durch die mechanische Verankerung des verfestigten flüssigen Stoffes bewirkt werden. Außerdem soll ein Abreißen der Verankerungselemente bei der Trennung des verfestigten flüssigen Stoffes von der Folie mit den Verankerungselementen weitgehend durch geeignete Auswahl a) an verformbaren Materialien und b) an gleitfähigen Formen der Verankerungselemente vermieden werden. Die Verankerungselemente sollen möglichst unverändert die Trennung überstehen (s. Fig. 1).The solution to this problem according to the invention can be found in the patent claims. It consists essentially in the fact that no fibrous layer is used for mechanical anchoring with the anchoring elements of a film. According to the invention, a liquid substance is applied directly to the film with the anchoring elements and solidified there. The lowest possible adhesion should occur between the film with the anchoring elements and the solidified liquid substance. The cohesion should largely be brought about by the mechanical anchoring of the solidified liquid substance. In addition, tearing off of the anchoring elements when separating the solidified liquid substance from the film with the anchoring elements is to be largely avoided by suitable selection of a) deformable materials and b) slidable forms of the anchoring elements. The anchoring elements should survive the separation as unchanged as possible (see FIG. 1).
Gegenstand der Erfindung ist die Verwendung einer Folie mit hervorragenden und/oder eingebetteten Verankerungselementen zur mechanischen Befestigung einer kohärenten Schicht auf mit einem Untergrund, wobei die kohärente Schicht nicht faserig ist. Die bevorzugten Ausführungsformen sind dem kennzeichnenden Merkmalen der Unteransprüche zu entnehmen.The invention relates to the use of a film with excellent and / or embedded anchoring elements for mechanically attaching a coherent layer to a substrate, the coherent layer not being fibrous. The preferred embodiments can be found in the characterizing features of the subclaims.
Gegenstand der Erfindung ist auch ein doppelseitiges Klebeband aus einer Folie mit Verankerungselementen auf mindestens einer Seite anstelle einer sonst üblichen glatten Folie, eines Gewebes oder eines Vlieses, wobei die Adhäsion der haftklebrigen Schicht der Folie auf einer Seite der Folie so niedrig ist, daß sie sich zerstörungsfrei abziehen läßt.The invention also relates to a double-sided adhesive tape made from a film with anchoring elements on at least one side instead of an otherwise usual smooth film, a woven fabric or a nonwoven, the adhesion of the pressure-sensitive layer of the film on one side of the film being so low that it becomes can be removed non-destructively.
Ein weiterer Gegenstand der Erfindung ist eine Folie mit eingebetteten Verankerungselementen.Another object of the invention is a film with embedded anchoring elements.
Ein weiterer Gegenstand der Erfindung ist ein Klettband aus Elastomeren, insbesondere thermoplastischen Elastomeren.Another object of the invention is a Velcro tape made of elastomers, in particular thermoplastic elastomers.
Unter Folien werden dünne, flächige, flexible Bahnen aus Metallen, Glas, Keramik und vor allem aus Kunststoffen verstanden. Ihre Dicke liegt zweckmäßigerweise im Bereich von 0,04 bis 2 mm. Sie kann aber auch darüber deutlich hinausgehen, wenn es auf die Flexibilität und leichte Aufwickelbarkeit der Bahnen nicht
ankommt. Insbesondere kommen hier Formteile in Frage, die bereits bei der Herstellung mit Verankerungselementen versehen werden, z.B. Platten oder Leisten.Foils are thin, flat, flexible webs made of metals, glass, ceramics and especially plastics. Their thickness is advantageously in the range from 0.04 to 2 mm. But it can also go much further if it does not depend on the flexibility and easy winding of the webs arrives. In particular, molded parts come into question here, which are already provided with anchoring elements during manufacture, for example plates or strips.
Die Fläche der Folie ist zweckentsprechend, insbesondere kann sie rund oder streifenförmig sein mit einer Breite von 0,2 bis 1 000, insbesondere von 1 bis 500 cm bei einer Länge von 0,05 bis 5 000, insbesondere von 0,1 bis 4 000 m. Die Folie ist in der Regel überwiegend vollflächig, d.h. sie weist keine oder nur kleine Poren oder Löcher auf. Die Summe der Löcher macht höchstens 10 % der Gesamtfläche aus. Form, Größe und Anzahl der Löcher sollten möglichst so sein, daß eine gewünschte Gas- bzw. Dampf-Durchlässigkeit erzielt wird, jedoch bei der Herstellung der kohärenten Schicht möglichst nichts von der noch flüssigen Phase durchdringt.The surface of the film is appropriate, in particular it can be round or strip-shaped with a width of 0.2 to 1,000, in particular from 1 to 500 cm, with a length of 0.05 to 5,000, in particular from 0.1 to 4,000 m. The film is usually predominantly full-surface, i.e. it has no or only small pores or holes. The sum of the holes makes up at most 10% of the total area. The shape, size and number of holes should, if possible, be such that a desired gas or vapor permeability is achieved, but as far as possible nothing of the still liquid phase penetrates during the production of the coherent layer.
Das Material der Folie ist entweder Metall oder Kunststoff, vorzugsweise Kunststoff, insbesondere Polyolefine wie Polyethylen und Polypropylen, Polyamid, Polyvinylchlorid, fluorhaltige Polymerisate, Silikon oder Polyurethan-Elastomere oder damit beschichtete Gebrauchsgegenstände. Insbesondere sind die Folien und Verankerungselemente aus dem gleichen Material. Sie können jedoch auch aus einer Materialkombination bestehen.The material of the film is either metal or plastic, preferably plastic, in particular polyolefins such as polyethylene and polypropylene, polyamide, polyvinyl chloride, fluorine-containing polymers, silicone or polyurethane elastomers or articles of daily use coated with them. In particular, the foils and anchoring elements are made of the same material. However, they can also consist of a combination of materials.
Derartige Folien sind in großer Anzahl bekannt. Bei der Auswahl in konkretem Fall ist vor allem die Formbarkeit und die Adhäsion der nichtfaserigen kohärenten Schicht zu berücksichtigen: Die Adhäsion sollte möglichst niedrig sein und die Formbarkeit der Verankerungselemente und/oder der nichtfaserigen kohärenten Schicht sollte so groß sein, daß die Verankerungselemente beim Trennen der Schichten überwiegend nicht funktionsunfähig oder gar abgerissen werden.Such films are known in large numbers. When choosing in a specific case, the formability and adhesion of the non-fibrous coherent layer must be taken into account: the adhesion should be as low as possible and the formability of the anchoring elements and / or the non-fibrous coherent layer should be so great that the anchoring elements when separating the Layers are mostly not functional or even torn off.
Die geringe Adhäsion zwischen Folie und nichtfaseriger kohärenter Schicht kann sich aus der Art der verwendeten Materialien ergeben. Sie kann aber auch durch eine Vorbehandlung vor Auftrag der flüssigen nichtfaserigen Schicht erhalten werden, z.B. durch Besprühen mit Wasser oder durch Beschichten mit Wachs oder ähnlichen schwer zu verklebenden Stoffen.The low adhesion between the film and the non-fibrous coherent layer can result from the type of materials used. However, it can also be obtained by pretreatment before application of the liquid non-fibrous layer, e.g. by spraying with water or by coating with wax or similar substances that are difficult to bond.
Die Formbarkeit der Verankerungselemente bzw. der kohärenten nichtfaserigen Schicht kann sich ebenfalls aus der Art der verwendeten Materialien ergeben oder durch physikalische Maßnahmen bedingt sein, z.B. durch Porosität.
Natürlich spielt auch die Form der Verankerungselemente eine Rolle. Besteht z.B. die nichtfaserige kohärente Schicht aus einem kaum verformbaren Material wie z.B. zement- oder gipsbasierten Bindemittel oder einem 2-K-Epoxid, dann sollten die Verankerungselemente im Material und in der Form relativ leicht verformbar und elastisch sein, z.B. aus Kunststoffen wie PE, PP, Silikon oder Gummi bestehen.The formability of the anchoring elements or the coherent non-fibrous layer can likewise result from the type of materials used or can be caused by physical measures, for example by porosity. Of course, the shape of the anchoring elements also plays a role. If, for example, the non-fibrous coherent layer consists of a barely deformable material such as cement or gypsum-based binder or a 2-component epoxy, the anchoring elements in the material and shape should be relatively easily deformable and elastic, e.g. made of plastics such as PE, PP , Silicone or rubber.
Eine Seite der Folie ist in der Regel glatt, so daß sie gegebenenfalls mit einer abgedeckten Klebstoffschicht oder mit Nägeln und Schrauben leicht auf dem Untergrund zu befestigen ist. Sie kann aber auch Verankerungselemente auf beiden Seiten enthalten, insbesondere dann, wenn der Untergrund faserig ist oder wenn der gleiche Klebstoff sowohl zum Befestigen der Folie auf dem Untergrund als auch zum Befestigen auf dem Substrat verwendet werden soll.One side of the film is usually smooth so that it can be easily attached to the surface with a covered layer of adhesive or with nails and screws. However, it can also contain anchoring elements on both sides, particularly if the substrate is fibrous or if the same adhesive is to be used both for attaching the film to the substrate and for attaching to the substrate.
Die Anzahl der Verankerungselemente hängt u.a. von der gewünschten Höhe der Haftung ab. Sie liegt im allgemeinen im Bereich von 0,1 bis 2 000, vorzugsweise von 1 bis 500 pro cm2.The number of anchoring elements depends, among other things, on the desired level of liability. It is generally in the range from 0.1 to 2,000, preferably from 1 to 500 per cm 2 .
Zumindest auf einer Seite weist die Folie Verankerungselemente auf.The film has anchoring elements on at least one side.
Ihre Länge beträgt mindestens 0,05, vorzugsweise mindestens 0,2 mm. IhreTheir length is at least 0.05, preferably at least 0.2 mm. Your
Länge übersteigt nur in seltenen Fällen 10 mm.Length rarely exceeds 10 mm.
Die Verankerungselemente können in die Folie eingebettet sein, vorzugsweise ragen sie jedoch über die Folienebene hinaus. Im letzten Fall kann es sich um typische Klettbänder, Antirutschbänder oder Stoppelfolien, wie z.B. um beflockteThe anchoring elements can be embedded in the film, but they preferably protrude beyond the film plane. In the latter case, it can be typical Velcro tapes, anti-slip tapes or stubble films, e.g. around flocked
Folien handeln.Trade slides.
Es sind jedoch nicht alle Formen an Verankerungselementen von üblichenHowever, not all forms of anchoring elements are common
Klettbändern gleich gut brauchbar. So sind Verankerungselemente mitVelcro straps can be used equally well. So are anchoring elements with
Hinterschneidungen (spitzer Winkel zwischen Stift und Haken) oder mit schlaufenförmigen Spiralen bzw. geschlossenen Schlaufen ungünstig. Das gleiche gilt für Verankerungselemente mit einer so intensiven Verankerung, daß sie beimUndercuts (acute angle between pin and hook) or with loop-shaped spirals or closed loops are unfavorable. The same applies to anchoring elements with such an intensive anchoring that they
Trennen zerrissen werden. So sollte bei einem pilzförmigen Verankerungselement der Querschnitts-Durchmesser des Pilzdaches kleiner als der 10fache Wert desTo be torn apart. In the case of a mushroom-shaped anchoring element, the cross-sectional diameter of the mushroom roof should be less than 10 times the value of the
Pilzschaftes sein. Natürlich sind Verankerungselemente mit Schlaufen besonders
ungünstig (s. Fig. 2). Günstig sind die Formen der Verankerungselemente, wenn sie ein Herausgleiten aus der kohärenten Schicht ermöglichen, ohne dabei funktionsunfähig oder gar abgerissen zu werden (s. Fig. 3). Besonders günstig sind Formen, wenn der Winkel zwischen dem Stift und dem Haken 90 ° oder größer ist (s. Fig. 4). Er muß jedoch kleiner als 180 ° sein, da sonst keine Verhakung auftritt, es sei denn, der Stift steht nicht senkrecht auf der Folie, sondern schräg. Wenn die Stifte dann noch in unterschiedliche Richtungen zeigen, bewirken sie ebenfalls eine Verankerung der nichtfaserigen kohärenten Schicht. Im Gegensatz zu üblichen Klettbändern können die Verankerungselemente bzw. deren Stifte auch einen Winkel von weniger als 90 ° zur Folie bilden, vorzugsweise einen Winkel von weniger als 45 °. Welcher Winkel am günstigsten ist, hängt unter anderem von der Verformbarkeit der kohärenten Schicht ab.Be mushroom shank. Anchoring elements with loops are of course special unfavorable (see Fig. 2). The forms of the anchoring elements are favorable if they allow them to slide out of the coherent layer without being inoperative or even torn off (see FIG. 3). Shapes are particularly favorable if the angle between the pin and the hook is 90 ° or greater (see FIG. 4). However, it must be less than 180 °, otherwise there will be no hooking, unless the pin is not perpendicular to the film, but at an angle. If the pins still point in different directions, they also anchor the non-fibrous coherent layer. In contrast to conventional Velcro strips, the anchoring elements or their pins can also form an angle of less than 90 ° to the film, preferably an angle of less than 45 °. Which angle is the most favorable depends, among other things, on the deformability of the coherent layer.
In der Regel sind die Enden der Verankerungselemente nicht stiftförmig, sondern verdickt (Köpfe), abgewinkelt oder abgebogen (Haken) oder abgeplattet (Pilzform). Die Fig. 1a, 1b und 1c zeigen schematisch die Änderung der Querschnittsform eines leicht verformbaren Verankerungselementes (1), a) während der ersten Beschichtung mit der kohärenten Schicht, b) während ihrer Ablösung im ausgehärteten Zustand und c) vor der zweiten Beschichtung. Der Pilzkopf wird beim Ablösen verformt. Die Rückstellung ist möglicherweise nicht 100 %ig (vgl. 1c) mit 1a) ).As a rule, the ends of the anchoring elements are not pin-shaped but rather thickened (heads), angled or bent (hooks) or flattened (mushroom shape). 1a, 1b and 1c schematically show the change in the cross-sectional shape of an easily deformable anchoring element (1), a) during the first coating with the coherent layer, b) during its detachment in the hardened state and c) before the second coating. The mushroom head is deformed when detached. The provision may not be 100% (cf. 1c) with 1a)).
Die Fig. 2a) bis 2f) zeigen die schematischen Querschnitte der Formen von Verankerungselementen, die auch bei einer leichten Verformbarkeit der nicht- faserigen kohärenten Schicht für eine schonende Ablösung ungünstig sind. Sie haben nämlich Hinterschneidungen (siehe 2a) und 2b) ) oder gar Schlaufen (2c), 2d) und 2e) ). Die Form 2f) ist wegen der Größenverhältnisse von Pilzkopf und Pilzschaft ungünstig.2a) to 2f) show the schematic cross sections of the shapes of anchoring elements, which are unfavorable for gentle detachment even when the non-fibrous coherent layer is easily deformable. They have undercuts (see 2a) and 2b)) or even loops (2c), 2d) and 2e)). Form 2f) is unfavorable because of the size relationship between the mushroom head and the mushroom shaft.
Die Fig. 3a), b), c), d) und e) zeigen schematisch einen Querschnitt durch die Formen von leicht verformbaren Verankerungselementen, die für eine schonende Ablösung günstig sind.
Die Fig. 4 zeigt schematisch einen Querschnitt durch eine Form eines Verankerungselementes aus einem schwer verformbaren Material, und zwar a) während der Beschichtung und b) während der Ablösung.3a), b), c), d) and e) schematically show a cross section through the shapes of easily deformable anchoring elements, which are favorable for a gentle detachment. 4 schematically shows a cross section through a shape of an anchoring element made of a material which is difficult to deform, namely a) during the coating and b) during the detachment.
Die Fig. 5 zeigt einen schematischen Querschnitt durch die Folie (2)mit einem eingebetteten Verankerungselement, und zwar a) nur ein eingebettetes Verankerungselement und b) eine Kombination von eingebettetem und hervorragendem Verankerungselement.FIG. 5 shows a schematic cross section through the film (2) with an embedded anchoring element, namely a) only an embedded anchoring element and b) a combination of an embedded and excellent anchoring element.
Bei einer nicht oder kaum verformbaren nichtfaserigen kohärenten Schicht bestehen die Verankerungselemente vorzugsweise aus einem Material, das in dünner Schicht von 0,05 bis 10 mm nicht oder nur wenig verformbar ist.In the case of a non-fibrous, coherent layer which can hardly be deformed, the anchoring elements preferably consist of a material which is not or only slightly deformable in a thin layer of 0.05 to 10 mm.
Der erfindungsgemäß hergestellte Verbund hält Zugbelastungen stand, die im Bereich des für die jeweilige Anwendung Bekannten liegen, ist jedoch bei Schälung um mindestens den Faktor 2, bevorzugt um den Faktor > 5 schwächer im Vergleich zu Schälwerten auf üblichen Substraten ohne die Folie mit den Verhakungselementen. Zur Trennung des Verbundes ist daher ein nur relativ geringer Kraftaufwand notwendig. Die Trennung erfolgt gezielt auf der Folie, wobei Verankerungselemente überwiegend funktionstüchtig erhalten bleiben und für eine erneute Belegung zur Verfügung stehen.The composite produced according to the invention withstands tensile loads which are in the range of what is known for the respective application, but is weaker by peeling by at least a factor of 2, preferably by a factor of> 5, compared to peel values on conventional substrates without the film with the interlocking elements. Only a relatively small amount of force is therefore required to separate the bond. The separation takes place in a targeted manner on the film, with anchoring elements mostly remaining functional and being available for a new assignment.
Weitere Vorteile der erf-ndungsgemäßen Befestigung sind:Further advantages of the fastening according to the invention are:
- Korrigierbarkeit des Verbundes, solange die nichtfaserige Schicht noch nicht fest ist,Correctability of the composite as long as the non-fibrous layer is not yet solid,
- weitgehend rückstandsfreie Trennung und- Largely residue-free separation and
- Spaltüberbrückung in beliebiger Höhe.- Gap bridging at any height.
- Ein Ausgleich von Unebenheiten des Untergrundes ist durch die unterschiedliche Dicke der nichtfaserigen Schicht leicht möglich.- Compensation for unevenness in the substrate is easily possible due to the different thickness of the non-fibrous layer.
Die nichtfaserige kohärente Schicht wird auf der Folie mit den Verankerungselementen erzeugt, indem ein verfestigbarer Stoff als Schicht in der gewünschten Dicke - vorzugsweise dicker als der Höhe der hervorragenden
Verankerungselementen auch im abgebundenen Zustand entspricht - flüssig aufgetragen wird. Im Falle der eingebetteten Verankerungselemente muß er so flüssig sein, daß er zumindest teilweise in die Hohlräume eindringt. Im Falle der hervorragenden Verankerungselemente kann er pastös bzw. knetbar sein, z.B. eine Spachtelmasse oder Knetmasse.The non-fibrous coherent layer is produced on the film with the anchoring elements by using a solidifiable material as a layer in the desired thickness - preferably thicker than the height of the outstanding one Anchoring elements even when set - corresponds to liquid application. In the case of the embedded anchoring elements, it must be so fluid that it at least partially penetrates into the cavities. In the case of the excellent anchoring elements, it can be pasty or kneadable, for example a filler or kneading compound.
Als pastös wird ein Viskositätsbereich von 20 000 bis 1 000 000 mPas gemessen nach Brookfield bei der Anwendungstemperatur im Bereich von -100 bis 300, vorzugsweise von -30 bis 200 °C angesehen. Auch dickflüssige Massen sind brauchbare, insbesondere bei horizontaler Anwendung. Dann liegt die Viskosität im Bereich von 2 000 bis 20 000 mPas. Auch Massen mit Viskositäten von mehr als 1 000 000 mPas können brauchbar sein, wenn sie sich in die Verankerungselemente einarbeiten lassen, z.B. durch Einkneten.A viscosity range from 20,000 to 1,000,000 mPas measured according to Brookfield at the application temperature in the range from -100 to 300, preferably from -30 to 200 ° C., is regarded as pasty. Viscous masses are also useful, especially for horizontal applications. Then the viscosity is in the range of 2,000 to 20,000 mPas. Masses with viscosities of more than 1,000,000 mPas can also be useful if they can be incorporated into the anchoring elements, e.g. by kneading.
Selbstverständlich ist bei der Beschichtung der Folie mit den Verankerungselementen darauf zu achten, daß diese nicht zerstört werden, sei es durch mechanische Kräfte oder durch Aufschmelzen, wenn z.B. erhitzte Massen wie Schmelzklebstoffe aufgetragen werden.When coating the film with the anchoring elements, it is of course important to ensure that they are not destroyed, either by mechanical forces or by melting, e.g. heated materials such as hot melt adhesives can be applied.
Die zunächst flüssige nichtfaserige Schicht bindet ab und wird fest, wobei eine so hohe Kohäsion auftritt, daß die nichtfaserige Schicht von der Folie trotz der Verankerungselemente zerstörungsfrei und überwiegend rückstandsfrei abgezogen werden kann. Diese feste, zusammenhänge Schicht ist in der Regel kompakt, kann aber auch porig sein.The initially liquid non-fibrous layer sets and becomes solid, with such high cohesion that the non-fibrous layer can be removed from the film in spite of the anchoring elements in a non-destructive and largely residue-free manner. This solid, coherent layer is usually compact, but can also be porous.
Es werden die üblichen anorganischen und organischen Bindemittel verwendet, z.B. hydraulische Bindemittel (z. B. Zement), Kalkmörtel, Gips, Wasserglas, Polymerdispersionen, Polymer-Schmelzen, Polymerlösungen, reaktive ein- oder zweikomponentige Systeme auf Kunststoffbasis mit den auch sonst üblichen Zusätzen. Konkrete nichtfaserige abbindende Schichten sind Putze, Lacke, Farben, Straßenmarkierungen, PU-Schäume, Dichtungsmassen. Bevorzugt sind Klebstoffe jeglicher Art, mit denen die Substrate bzw. Elemente auch ohne Folien befestigt werden können.
Die kohärente nichtfaserige Schicht ist im ausgehärteten Zustand gegenüber der Folie mit den Verankerungselementen nicht oder nur geringfügig adhäsiv. Die Adhäsion beträgt höchstens 100, bevorzugt höchstens 50 % des Wertes für die mechanische Verankerung. Entscheidend ist, daß beim späteren Abziehen der Schicht ihre innere Festigkeit höher als die Summe der Haftfestigkeit und der mechanischen Verankerung ist.The usual inorganic and organic binders are used, e.g. hydraulic binders (e.g. cement), lime mortar, gypsum, water glass, polymer dispersions, polymer melts, polymer solutions, reactive one- or two-component systems based on plastics with the usual additives. Specific non-fibrous setting layers are plasters, varnishes, paints, road markings, PU foams, sealing compounds. Adhesives of any kind are preferred, with which the substrates or elements can also be attached without films. In the hardened state, the coherent non-fibrous layer is not or only slightly adhesive to the film with the anchoring elements. The adhesion is at most 100, preferably at most 50% of the value for the mechanical anchoring. It is crucial that when the layer is subsequently pulled off, its internal strength is higher than the sum of the adhesive strength and the mechanical anchoring.
Die kohärente nichtfaserige Schicht ist vorzugsweise ein Klebstoff bzw. enthält für Klebstoffe typische Bindemittel, d.h. er verbindet den Untergrund mit einer Deckschicht.The coherent non-fibrous layer is preferably an adhesive or contains binders typical of adhesives, i.e. it connects the subsurface with a top layer.
Bei der Deckschicht bzw. dem Susbstrat handelte es sich in der Regel um eine Schutz- oder Dekorschicht, z.B. um Wand-, Decken- und Bodenbeläge für Gebäude oder Fahrzeuge, z.B. Tapeten, Parkett, Laminate, Isolierplatten, Schutzfolien, Fliesen, Bodenplatten, Marmorplatten, Steinzeug, Dachplatten, Teppiche, Bilder, Regale, Glasscheiben, Ziegel, Abdeckungen, Verkleidungen usw..The cover layer or the substrate was usually a protective or decorative layer, e.g. around wall, ceiling and floor coverings for buildings or vehicles, e.g. Wallpaper, parquet, laminates, insulating panels, protective films, tiles, floor panels, marble panels, stoneware, roof panels, carpets, pictures, shelves, glass panes, bricks, covers, claddings, etc.
Bei dem Untergrund handelt es sich um Mauerwerk, Putze, Beton, Estriche, Spachtelmassen, Metall-, Holz- und Kunststoffoberflächen, Fliesen, Glas.The substrate is masonry, plaster, concrete, screed, filler, metal, wood and plastic surfaces, tiles, glass.
Die Folie dichtet den Untergrund entsprechend ihrer Dicke und ihrer Material-Art wie üblich ab. Die Durchlässigkeit für Luft, Wasserdampf und andere Gase kann aber durch eine gewisse Porosität verbessert werden.The film seals the substrate according to its thickness and type of material as usual. The permeability to air, water vapor and other gases can be improved by a certain porosity.
Aufgrund dieser Vorteile eignet sich die Erfindung für viele Anwendungen. Einige seien in den folgenden Figuren beispielhaft genannt:Because of these advantages, the invention is suitable for many applications. Some are mentioned in the following figures as examples:

Dieser Verbund ist typisch für viele Anwendungen, bei denen die abgebundene nichtfaserige kohärente Schicht genügt, z.B. Putz, evtl. ergänzt durch einen Anstrich.This composite is typical of many applications where the set non-fibrous coherent layer is sufficient, e.g. Plaster, possibly supplemented with a coat of paint.
Fig. 9 zeigt einen schematischen Querschnitt durch einen abgewinkelten erfindungsgemäßen Verbund aus a) einer Fugendichtungsmasse als kohärenter Schicht (4), b) einer Folie (2) mit Verhakungselementen (1), c) einer Klebstoffschicht (4) und d) dem Untergrund (6).9 shows a schematic cross section through an angled composite according to the invention comprising a) a joint sealing compound as a coherent layer (4), b) a film (2) with interlocking elements (1), c) an adhesive layer (4) and d) the substrate ( 6).
Dieser Verbund eignet sich insbesondere zum Abdichten von Fugen zwischen der Wand und der Badewanne, da er auf Dauer sehr gut abdichtet und die Fugendichtungsmasse leicht ausgewechselt werden kann, wenn sie unansehnlich geworden ist.
Fig. 10 zeigt einen schematischen Querschnitt durch einen erfindungsgemäßen Verbund mit relativ vielen Schichten, nämlich a) Belag (2) mit Verhakungselementen (2), b) Klebstoff (4), c) Folie (2) beidseitig mit Verhakungselementen (1), d) Klebstoff (4) sowie e) Untergrund (6) mit Verhakungselementen (1).This composite is particularly suitable for sealing joints between the wall and the bathtub, as it seals very well in the long term and the joint sealant can be easily replaced if it has become unsightly. Fig. 10 shows a schematic cross section through a composite according to the invention with relatively many layers, namely a) covering (2) with interlocking elements (2), b) adhesive (4), c) film (2) on both sides with interlocking elements (1), d ) Adhesive (4) and e) substrate (6) with interlocking elements (1).
Ein derartiger Verbund ist z.B. dann zweckmäßig, wenn die Folie mit Verhakungselementen mit einem einzigen Klebstoff einerseits mit dem Untergrund und andererseits mit einem Belag verbunden werden soll.
Such a composite is useful, for example, if the film with interlocking elements is to be connected with the substrate on the one hand with a single adhesive and on the other hand with a covering.
