Definitions

• 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.
• 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.
• Conventional wallpaper paste and adhesives e.g. with the known wallpaper pastes and adhesives based on methyl cellulose, carboxymethyl cellulose and / or starch.
• 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.
• 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.
• 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.
• the wallpaper 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.
• 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.
• a so-called alternating base or a dispersion set is to be first apply to the adhesive on the wall to be papered.
• a so-called alternating base or a dispersion set is depending on the nature of the wall, i.e. of the substrate, applied once or twice in different dilution ratios.
• the corresponding paper wallpaper can then be stuck onto it with a customary methyl cellulose, carboxymethyl cellulose or methyl cellulose adhesive.
• wallpapers glued with starch paste cannot be peeled off, just as little with heavy wall coverings that e.g. were laid with dispersion adhesives.
• the setting of the various adhesive forces is difficult and, under certain circumstances, the surface, i.e. the wall, get hurt.
• this then requires the application of fillers before wallpapering again in order to prepare the surface accordingly for the new wallpapering.
• 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.
• 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.
• the invention consists of a waste W irrvlies to which a very thin film is layered or laminated.
• the nonwoven can consist of all the usual materials for nonwovens and can comprise all types of nonwoven.
• the nonwoven consists of polyolefins, e.g. Polymers of ethylene, propylene, butylene or mixtures thereof.
• the basis weight is in the range from 30 to 150 g / m 2 and preferably from 50 to 90 g / m 2 .
• 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.
• the film coating is 5 to 30 g / m 2 , preferably 15 to 25 g / m 2 .
• Thin silicone foils or siliconized foils can also be used as plastic foils.
• 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.
• the waste can be glued to all surfaces (walls) that occur in practice.
• Suitable adhesives are e.g. the well-known dispersion glue.
• 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.
• 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.
• 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.
• 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.
• 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.
• Example 1 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.
• waste according to the invention made of a 70 g polyolefin fleece coated with a thin polyethylene film was glued to the fleece side with an unfilled, high-quality adhesive.
• a medium-quality wallpaper paper weight approx. 140 g / m 2
• Example 2 The same wallpaper as in Example 2 was glued to the same substrate with the same wallpaper paste in the same batch ratio, but again without using the waste according to the invention.
• waste according to the invention made of a 90 g polyolefin fleece coated with a polyethylene film was glued to the fleece side with an unfilled, high-quality adhesive.
• a textile-lined PVC wallpaper (weight approx. 270 g / m 2 ) was glued with an unfilled, high-quality adhesive.
• waste according to the invention made of a 60 g polyolefin fleece coated with a polyethylene film was glued to the fleece side with an unfilled, high-quality adhesive. After 24 hours, a structure was pete glued with a special paste based on methyl cellulose in a 1:20 ratio. After another 24 hours, the wallpaper was painted with a weatherproof emulsion paint.
• Example 4 The same structural wallpaper was glued to the same surface as in Example 4 with the same special paste in the same batch ratio.
• This textured wallpaper was painted with a weatherproof emulsion paint after 24 hours.
• waste according to the invention made of a 65g polyolefin nonwoven coated with a thin polyethylene film was glued to the nonwoven side with an unfilled, high-quality adhesive.
• both medium-quality wallpaper paper weight approx. 140 g / m 2
• both wallpapers could be removed in one piece from the waste dry, sheet by sheet, without damaging the film side.
