Description

Die Erfindung betrifft eine spezielle Makulatur mit einer dehäsiv eingestellten Oberfläche, die sich für das Aufbringen und Kleben für Tapeten bzw. Wandbeläge aller Art eignet und von der die Tapeten bzw. Wandbeläge leicht zu entfernen sind.The invention relates to a special waste with a dehesively adjusted surface, which is suitable for applying and gluing for wallpapers or wall coverings of all kinds and from which the wallpapers or wall coverings are easy to remove.

Tapeten und Wandbeläge werden im allgemeinen auf Wänden unter Verwendung üblicher Tapetenkleister und Klebstoffe befestigt, z.B. mit den bekannten Tapetenkleistern und -klebstoffen auf Basis Methylcellulose, Carboxymethylcellulose und/oder Stärke. Eine Reihe von Problemen wirft die spätere Entfernung von Tapeten auf, wenn neue Tapeten aufgebracht werden sollen. Dazu ist es nötig, die alten Tapeten und Wandbeläge zu entfernen. Diese Entfernung ist im allgemeinen schwierig und zeitraubend. Üblicherweise wird die Oberfläche der Tapete mit Wasser und/oder einem Tapetenablöser durchweicht, um die Tapete und den Tapetenkleister oder Tapetenklebstoff zu quellen. Anschließend kann dann von der Wand entfernt werden. Besonders problematisch wird die Sache bei wasserfesten Tapeten und Wandbelägen oder solchen, die an ihrer Oberfläche eine wasserfeste Schicht tragen. Dazu muß die wasserfeste Schicht z.B. mit einer Stachelwalze zunächst zerstört werden.Wallpapers and wall coverings are generally attached to walls using conventional wallpaper paste and adhesives, e.g. with the known wallpaper pastes and adhesives based on methyl cellulose, carboxymethyl cellulose and / or starch. There are a number of problems with the later removal of wallpapers when new wallpapers are to be applied. To do this, it is necessary to remove the old wallpaper and wall coverings. This removal is generally difficult and time consuming. Usually, the surface of the wallpaper is soaked with water and / or a wallpaper stripper in order to swell the wallpaper and the wallpaper paste or wallpaper adhesive. You can then remove it from the wall. Things become particularly problematic with waterproof wallpapers and wall coverings or those that have a waterproof layer on their surface. To do this, the waterproof layer must e.g. be destroyed with a spiked roller first.

Zum Auswechseln bzw. Entfernen von Tapeten, Papieren und den verschiedensten Wandbelägen, die hauptsächlich aus Weich-Polyvinylchlorid, Polyvinylchloridschaum undFor replacing or removing wallpaper, papers and a wide variety of wall coverings, which mainly consist of soft polyvinyl chloride, polyvinyl chloride foam and

Polystyrol bestehen, werden im allgemeinen die folgenden Techniken angewandt:

  • a) Die Tapete oder der Wandbelag wird auf eine spaltbare Makulatur geklebt. Im einzelnen wird zunächst auf die Wand der Spezialkleber oder -kleister aufgebracht, und in das offene Kleisterbett die spaltbare Makulatur eingelegt. Diese Makulatur dient dann für die nachfolgende Verlegung von Tapeten bzw. Wandbelägen unter Verwendung üblicher Tapetenkleister bzw. Wandbelagklebstoffe.
Polystyrene, the following techniques are generally used:
  • a) The wallpaper or wall covering is glued onto a splittable waste. In detail, the S is first made to the wall or pezialkleber -kleister applied, and inserted the cleavable paper waste in the open paste bed. This waste is then used for the subsequent laying of wallpaper or wall coverings using conventional wallpaper paste or wall covering adhesives.

Beim Entfernen der Tapete wird die Makulatur gespalten, so daß sich zwar die auf die spaltbare Makulatur geklebten Tapeten oder Wandbeläge entfernen lassen, aber dieser Vorgang nur einmal möglich ist und vor Aufbringen der neuen Tapete es nötig ist, eine neue spaltbare Makulatur aufzubringen und ggfls. den verbliebenen Rest der ersten spaltbaren Makulatur zu entfernen. Dies ist natürlich unwirtschaftlich, zeitraubend und kostspielig.When the wallpaper is removed, the waste is split so that the wallpaper or wall coverings glued to the split waste can be removed, but this process is only possible once and before the new wallpaper is applied it is necessary to apply a new split waste and if necessary. remove the rest of the first fissile waste. Of course, this is uneconomical, time-consuming and expensive.

b) Das Trockenabziehen von Tapeten kann dadurch bewirkt werden, daß man die Tapetenrückseite mit einer dehäsiven Beschichtung versieht oder aber auch die Wand mit einer dehäsiven Imprägnierung versieht. Anschließend wird mit einem üblichen Kleister verklebt. .Allerdings sollte der Klebstoff in geeigneter Weise auf die dehäsive Ausrüstung abgestellt sein. Es ist auch bekannt, restlos trockenabreibbare Tapeten dadurch herzustellen, daß sie eine Zwischenschicht zwischen der Tapete und der Kleister- oder Klebschicht , mit der sie an den Untergrund bzw. die Wand befestigt sind, aufweisen. Die GB-PS 1 184 563 beschreibt eine trockenabziehbare Tapete, die aus einem nicht gewobenen faserförmigen flächigen Material besteht, das auf der der Wand zugekehrten Seite zunächst eine harz-oder wachsartige spaltbare Beschichtung und darauf eine wasseraktivierbare Klebstoffschicht aufweist. Nach Aktivierung der Klebschicht durch Wasser wird die Tapete an die Wand gebunden, ist jedoch später abziehbar, ohne daß man sie vorher mit Wasser und/oder einem Tapetenablösmittel einweichen muß. Auch hier liegt der Nachteil in einer genauen Abstimmung der Bindekräfte der einzelnen Schichten sowie darin, daß sich beim Abziehen Schädigungen des Untergrundes kaum vermeiden lassen.b) The dry peeling of wallpaper can be effected by providing the back of the wallpaper with a dehesive coating or by providing the wall with a dehesive impregnation. Then it is glued with a conventional paste. However, the adhesive should be placed on the adhesive equipment in a suitable manner. It is also known to produce completely dry-abradable wallpapers by having an intermediate layer between the wallpaper and the paste or adhesive layer with which they are attached to the substrate or the wall. GB-PS 1 184 563 describes one dry-strippable wallpaper, which consists of a non-woven fibrous sheet-like material which on the side facing the wall initially has a resin-like or wax-like cleavable coating and then a water-activatable adhesive layer. After the adhesive layer has been activated by water, the wallpaper is bound to the wall, but can be removed later without having to soak it beforehand with water and / or a wallpaper release agent. Here, too, the disadvantage lies in the precise coordination of the binding forces of the individual layers and in the fact that damage to the substrate can hardly be avoided when peeling off.

c) Eine weitere Möglichkeit ist, auf die-zu tapezierende Wand zunächst einen sog. Wechselgrund oder eine abhäsiv eingestellte Dispersion aufzubringen. Beispielsweise wird ein solcher Wechselgrund je nach Beschaffenheit der Wand, d.h. des Untergrundes, ein- bis zweimal in verschiedenen Verdünnungsverhältnissen aufgetragen. Nach einer Trockenzeit von mehreren Stunden, üblicherweise über Nacht, kann dann darauf mit einem üblichen Methylcellulose-, Carboxymethylcellulose-oder Methylcellulose-Spezialkleber die entsprechende Papiertapete geklebt werden. Mit Stärkekleister verklebte Tapeten lassen sich dagegen nicht abziehen, ebensowenig bei schweren Wandbelägen, die z.B. mit Dispersionsklebern verlegt wurden. Auch hier ist die Einstellung der verschiedenen Klebekräfte schwierig und unter Umständen kann beim Abziehen der Untergrund, d.h. die Wand, verletzt werden. Dies erfordert dann jedoch vor dem erneuten Tapezieren die Aufbringung von Spachtelmassen, um den Untergrund entsprechend für das erneute Tapezieren vorzubereiten.c) Another option is to first apply a so-called alternating base or a dispersion set to the adhesive on the wall to be papered. For example, such a change reason is depending on the nature of the wall, i.e. of the substrate, applied once or twice in different dilution ratios. After a drying time of several hours, usually overnight, the corresponding paper wallpaper can then be stuck onto it with a customary methyl cellulose, carboxymethyl cellulose or methyl cellulose adhesive. On the other hand, wallpapers glued with starch paste cannot be peeled off, just as little with heavy wall coverings that e.g. were laid with dispersion adhesives. Here, too, the setting of the various adhesive forces is difficult and, under certain circumstances, the surface, i.e. the wall, get hurt. However, this then requires the application of fillers before wallpapering again in order to prepare the surface accordingly for the new wallpapering.

d) Bei speziellen Wandbelägen ist es auch möglich, die Verlegung unter Verwendung spezieller geeigneter wässriger Klebstoffe, die teilweise in Form von Dispersionen vorliegen, direkt auf die Wand vorzunehmen (Versois-Technik). Dies hat jedoch den Nachteil, daß beim Abreißen der Tapete Kleber- oder Kleisterreste in unregelmäßiger Form an der Wand verbleiben und auch Putzbestandteile aus der Wand mit der Tapete abgezogen bzw. herausgerissen werden.d) With special wall coverings, it is also possible to lay them directly on the wall using special, suitable aqueous adhesives, some of which are in the form of dispersions (Versois technique). However, this has the disadvantage that when the wallpaper is torn off, adhesive or paste residues remain in an irregular shape on the wall and also plaster components are pulled off or torn out of the wall with the wallpaper.

Dem Fachmann ist bekannt, daß verschiedene Untergründe, d.h. verschiedene Wandbeschaffenheiten verschiedene verlegetechnische Anforderungen an Wandbeläge und speziell an die Wandbelagklebstoffe stellen.It is known to those skilled in the art that various substrates, i.e. Different wall textures have different laying requirements for wall coverings and especially for wall covering adhesives.

Die Erfindung stellt sich die Aufgabe, eine Makulatur zu schaffen, bei der die oben erwähnten Nachteile des Standes der Technik nicht mehr auftreten und die auf alle in der Praxis anfallende Untergründe geklebt werden kann, auf die mit allen üblichen Tapetenkleistertypen Wandbelagstoffe einschl. solcher auf Dispersionsbasis and aller Tapetensorten sowie auch schwerer Wandbeläge aufgebracht werden können und von der sich die Tapete oder der Wandbelag wiederholt auf einfache Weise abziehen läßt, ohne zu Schädigungen des Untergrundes, d.h. der Wand und/oder der Makulatur zu führen, so daß die Makulatur ohne aufwendige Vorbereitung des Untergrundes für zu erneuernde Tapezierungen eingesetzt werden kann.The object of the invention is to create paper waste in which the above-mentioned disadvantages of the prior art no longer occur and which can be glued to all substrates which occur in practice, onto which wall covering materials, including those based on dispersion, are used with all conventional types of wallpaper paste can be applied to all types of wallpaper as well as heavy wall coverings and from which the wallpaper or wall covering can be pulled off repeatedly in a simple manner without causing damage to the substrate, ie of the wall and / or the waste, so that the waste can be used for wallpapering to be renewed without time-consuming preparation of the substrate.

Gelöst wird die Aufgabe durch die erfindungsgemäß einzusetzende Makulatur, die aus einem Vlies besteht, auf das eine Kunststoff-Folie laminiert ist.The object is achieved by the waste to be used according to the invention, which consists of a nonwoven on which a plastic film is laminated.

Insbesondere besteht die erfindungsgemäße Makulatur aus einem Wirrvlies, auf das eine sehr dünne Folie geschichtet oder laminiert ist.Specifically, the invention consists of a waste W irrvlies to which a very thin film is layered or laminated.

Das Vlies kann aus allen üblichen Materialien für Vliese bestehen und kann alle Vliesarten umfassen. Beispielsweise besteht das Vlies aus Polyolefinen, z.B. Polymeren des Ethylens, Propylens, Butylens oder deren Gemischen.The nonwoven can consist of all the usual materials for nonwovens and can comprise all types of nonwoven. For example, the nonwoven consists of polyolefins, e.g. Polymers of ethylene, propylene, butylene or mixtures thereof.

Das Flächengewicht liegt im Bereich von 30 bis 150 g/m2 und vorzugsweise von 50 bis 90 g/m2.The basis weight is in the range from 30 to 150 g / m 2 and preferably from 50 to 90 g / m 2 .

Die dünne Kunststoffolie besteht aus einem Kunststoff mit einer niedrig-energetischen Oberfläche.Beispiele sind Polyolefine wie Polyethylen, Polypropylen oder -Polyisobutylen, und zwar vorzugsweise die' Homopolymeren dieser Olefine. Bevorzugt wird eine sehr dünne Polyethylenfolie.,The thin plastic film consists of a plastic with a low-energy surface. Examples are polyolefins such as polyethylene, polypropylene or polyisobutylene, and preferably the 'homopolymers of these olefins. A very thin polyethylene film is preferred.

Die Folienbeschichtung beträgt 5 bis 30 g/m2, vorzugsweise 15 bis 25 g/m2.The film coating is 5 to 30 g / m 2 , preferably 15 to 25 g / m 2 .

Als Kunststoffolien können auch dünne Silikonfolien oder silikonisierte Folien verwendet werden.Thin silicone foils or siliconized foils can also be used as plastic foils.

Die für die erfindungsgemäße Makulatur verwendeten Vliese werden auf übliche Weise hergestellt. Die für die erfindungsgemäße Makulatur hergestellten dünnen Kunststoffolien werden ebenfalls auf übliche bekannte . Weise hergestellt.The nonwovens used for the waste according to the invention are produced in the usual way. The thin plastic films produced for the waste according to the invention are also known in the usual way. Manufactured way.

Mit der erfindungsgemäßen Makulatur werden eine Reihe von Verbesserungen und Vorteile erzielt. Die Makulatur kann auf alle in der Praxis anfallenden Untergründe (Wände) geklebt werden. Als Klebstoff eignen sich dafür z.B. die bekannten Dispersionskleber.A number of improvements and advantages are achieved with the waste according to the invention. The waste can be glued to all surfaces (walls) that occur in practice. Suitable adhesives are e.g. the well-known dispersion glue.

Auf die erfindungsgemäße Makulatur können sowohl die üblichen Tapetenpapiere als auch die üblichen schweren Wandbeläge, die beispielsweise aus Weichpolyvinylchlorid, Polyvinylchloridschaum oder Polystyrol bestehen, verlegt werden. Bei Papiertapeten kann dies mit den üblichen Kleistern auf Basis von Methylcellulose, Carboxymethylcellulose und/oder Stärke erfolgen. Schwere Wandbeläge können mit den üblichen Dispersionsklebern aufgeklebt werden.Both the usual wallpaper papers and the usual heavy wall coverings, which consist, for example, of soft polyvinyl chloride, polyvinyl chloride foam or polystyrene, can be laid on the waste according to the invention. In the case of paper wallpapers, this can be done with the usual pastes based on methyl cellulose, carboxymethyl cellulose and / or starch. Heavy wall coverings can be glued on with the usual dispersion adhesives.

Obwohl die so aufgebrachten Tapeten bzw. Wandbeläge nach der Wandtrocknung eine feste Haftung auf der erfindungsgemäßen Makulatur aufweisen, können ohne Zerstörung der Makulatur mindestens drei Tapetenwechsel durch einfaches Entfernen der alten Tapeten vorgenommen werden, ohne daß man ein Vorspachteln der Oberfläche vornehmen müsste. Diese wiederholt mögliche Abziehbarkeit der Wandbeläge und Tapeten ist von erheblichem Vorteil.Although the wallpapers or wall coverings applied in this way have a firm adhesion to the waste according to the invention after wall drying, at least three wallpaper changes can be carried out by simply removing the old wallpapers without destroying the waste, without having to pre-fill the surface. This possibility of repeatedly removing the wall coverings and wallpaper is of considerable advantage.

Die für die erfindungsgemäße Makulatur verwendeten Polyolefinvliese haben im allgemeinen die folgenden Eigenschaften in den angegebenen Bereichen:

  • Die Polyolefinvliese sind entweder ungenadelt oder weisen eine Perforation/Nadelung auf, die Werte bis zu 350 000 Einstichen/m2 erreichen kann. Die Vliese sollen ein mittleres Gewicht von ca 30 bis 150 g/m2, eine Materialstärke von 0,10 bis 0,4 mm haben, sowie bezüglich der Vliesspaltung zwischen 10 und 60 N/10cm liegen.
The polyolefin nonwovens used for the waste according to the invention generally have the following properties in the ranges specified:
  • The polyolefin nonwovens are either not needled or have perforation / needling that can reach values of up to 350,000 punctures / m 2 . The nonwovens should have an average weight of approx. 30 to 150 g / m 2 , a material thickness of 0.10 to 0.4 mm, and should be between 10 and 60 N / 10cm with regard to the splitting of the nonwovens.

Die Vliesspaltung wurde wie folgt ermittelt:

  • Auf einen Streifen einer ca 6 mm dicken Asbestzementplatte von 120 x 400 mm wurde das Polyolefinvlies mit einem hochprozentigen, ungefüllten Dispersionskleber geklebt. Die so verklebte Probe wird an ihrem nicht geklebten Ende durch eine Zugkraft, die in einem Abzugswinkel von 90° angreift, so lange beansprucht, bis die Klebschicht reißt und die Probe vom Untergrund
getrennt ist, bzw. eine Spaltung eintritt. Die dazu erforderliche Kraft wird durch eine geeignete Meßvorrichtung ermittelt.Fleece cleavage was determined as follows:
  • The polyolefin fleece was glued to a strip of an approximately 6 mm thick asbestos cement plate of 120 x 400 mm with a high-percentage, unfilled dispersion adhesive. The sample that is bonded in this way is subjected to a tensile force at its non-bonded end, which acts at a pull-off angle of 90 °, until the adhesive layer breaks and the sample from the substrate
is separated, or a split occurs. The force required for this is determined by a suitable measuring device.

Die Erfindung wird anhand der folgenden Beispiele und Vergleichsbeispiele weiter erläutert. Als Polyolefinvlies wurde ein Vlies mit folgenden Eigenschaften in den Beispielen eingesetzt:

  • a) Polyolefinvlies ohne Nadelung
  • b) Perforation/Nadelung ca 250 000 Einstiche/m2 mittleres Gewicht ca 60 - 80 g/m2 Materialstärke ca 0,18 bis 0,23 mm Festigkeit des Vlieses (Vliesspaltung) ca 20 - 30 N/10 cm.
The invention is further illustrated by the following examples and comparative examples. A nonwoven with the following properties was used as the polyolefin nonwoven in the examples:
  • a) Polyolefin fleece without needling
  • b) Perforation / needling approx. 250,000 punctures / m 2 average weight approx. 60 - 80 g / m 2 material thickness approx. 0.18 to 0.23 mm strength of the fleece (fleece splitting) approx. 20 - 30 N / 10 cm.

Beispiel 1example 1

Auf einem grundierten Kalkfilz-Putz wurde eine erfindungsgemäße Makulatur aus einem mit einer dünnen Polyethylenfolie beschichteten Polyolefinvlies auf der Vliesseite mit einem ungefüllten, hochwertigen Kleb- stoff geklebt. Nach 24 Stunden wurde ein Wandbelag aus PVCschaum (Materialgewicht ca 700 g/m2, Dicke ca 2 - 2,5 mm) mit einem gefüllten hochwertigen Dispersionsklebstoff auf die Polyethylenfolienseite der erfindungsgemäßen Makulatur.verklebt.On a primed Kalkfilz plaster according to the invention a waste of a coated with a thin polyolefin nonwoven polyethylene film was on the nonwoven side with an unfilled, high quality adhesives - bonded fabric. After 24 hours, a wall covering made of PVC foam (material weight approx. 700 g / m 2 , thickness approx. 2-2.5 mm) was glued to the polyethylene film side of the waste according to the invention with a filled high-quality dispersion adhesive.

Festigkeitsprüfungen nach 8 Tagen zeigten, daß sich der Wandbelag ohne weiteres in einem Stück von der erfindungsgemäßen Makulatur abziehen ließ, wobei bei der Entfernung der gesamte Klebstoff an der Belagrückseite haftete und die Polyethylenfolienoberfläche frei von Klebstoff war.Strength tests after 8 days showed that the wall covering could easily be removed in one piece from the waste according to the invention, the entire adhesive adhering to the back of the covering during removal and the polyethylene film surface being free of adhesive.

Dieser Vorgang wurde nach 2maliger Wiederholung angestellt, ohne daß der Abzugeffekt beeinträchtigt oder die Makulatur beschädigt worden wäre.This process was started after repeated repetition without the withdrawal effect being impaired or the waste being damaged.

Vergleichsbeispiel 1Comparative Example 1

Auf den gleichen Untergrund wie in Beispiel 1 wurde der gleiche Wandbelag wie in Beispiel 1 mit dem gleichen Klebstoff aber ohne Einsatz der erfindungsgemäßen Makulatur verklebt.The same wall covering as in Example 1 was bonded to the same substrate as in Example 1 with the same adhesive but without the waste according to the invention.

Festigkeitsprüfungen nach 8 Tagen zeigten, daß der Wandbelag beim Entfernen zum Teil zerstört wurde und zum Teil mit der oberen Putzschicht des Untergrundes abgezogen wurde.Strength tests after 8 days showed that the wall covering was partly destroyed when removed and partly removed with the upper plaster layer of the substrate.
