Definitions

  • the invention initially relates to an embossed wallpaper with a single carrier layer, from the front of which protrusions protrude.
  • the backing layer consists either of a layer (simplex paper) or of top and bottom paper (duplex paper), which are articulated together.
  • Such wallpapers are still difficult to attach because only the webs lying between the forms can be provided with an adhesive layer with which the wallpaper can then be attached to a wall.
  • some of these wallpapers are made of plastic (PVC).
  • PVC plastic
  • such wallpapers form hydrochloric acid in the event of a fire, which can lead to health damage, so they must not be burned as waste, but must be disposed of in landfills.
  • the PVC wallpaper in the living area can release residual monomers that are absorbed by the human body with harmful effects.
  • the object of the invention is to design an embossed wallpaper of the type mentioned at the outset in such a way that it is relatively light in structure, and the characteristics are retained even when wallpapering, nevertheless inexpensive production of the wallpaper should be possible.
  • the back of the backing layer should have a good affinity for wallpaper paste and the backing layer should later be smoothly removable from a wall without remnants of the embossed wallpaper remaining on the wall.
  • the shape stability is maintained when the embossed wallpaper is soaked during installation, so that such wallpapers are easier to install.
  • the smooth back enables the embossed wallpaper to be laid safely. Thereby. that the cavities are now filled, the density of the wallpaper paper or a mineral fiber fleece serving as a carrier can be reduced.
  • the elastic filling compound also ensures that embossed wallpaper webs can be rolled up without a so-called corrugated cardboard effect occurring.
  • the special design of the binding forces means that if the embossed wallpaper is to be removed, the embossed wallpaper can be pulled off the wall as a unit without any residues remaining on the wall.
  • the filler contains binding agents. through which an intimate connection is established during curing within the filling compound and between the carrier layer and the filling compound, in order to ensure secure cohesion of the embossed wallpaper even when torn off a wall.
  • the binding agents are constructed as hydrophobic agents. This ensures that there is an intimate connection between the backing and the filler before the curing process, while less moisture can penetrate into the filler and the backing after the wallpaper paste has hardened and applied, so that the binding forces between the embossed wallpaper and the wall to be wallpapered are reduced. It is particularly favorable here if the binding agents contain waxes and / or stearates.
  • the filling compound advantageously extends as a continuous layer on the back. This ensures in a simple manner. that a smooth back of the embossed wallpaper is achieved. It is also advisable to design the filling compound as a small-pore, in particular mechanical, foam. since it is further possible to reduce the specific weight of the embossed wallpaper, the elasticity of the filling compound is also increased.
  • the filling compound is composed of a binder and a filler, so as to meet the different conditions that are placed on the filling compound.
  • the binder securely attaches the filling compound to the embossed wallpaper, while the filler itself enables inexpensive production.
  • the binder is the same as the binding agent or at least partially contains it.
  • the proportion of the filler is advantageously greater than the proportion of the binder, it being shown that in a favorable embodiment the proportion of the fillers is approximately 60 percent and the proportion of the binder is 40 percent.
  • the filler consists of an environmentally friendly material, in particular kaolin, gypsum, talc, wood flour, chalk.
  • an environmentally friendly material in particular kaolin, gypsum, talc, wood flour, chalk.
  • the binder is also advantageously made from an environmentally friendly material, in particular from acrylic latex, natural rubber, natural resin, tree resin, rosin, beeswax, casein, copal resin and, or starch.
  • the filling material arranged in the cavity is provided with capillaries so as to be able to increase the breathability of the wallpaper, while at the same time ensuring that any moisture that may occur on the walls equipped with the wallpaper is safely drained away and does not soften the Wallpaper leads.
  • the invention also relates to a method for producing a carrier wallpaper with a single carrier layer, from the front of which protrusions protrude, in which the carrier layer softens, is provided with protrusions and is then dried.
  • the production was relatively complex, since the wallpapers easily deformed during the manufacture of the embossments in the carrier layer.
  • the task is. to produce cheaply the embossed wallpaper according to the invention.
  • the expressions should certainly be able to be produced without the expressions partially regressing.
  • firm cohesion between the carrier layer and the filling compound should be ensured.
  • a filling compound in particular a foam-like filling compound which has just been foamed up shortly before, is poured into the cavities immediately after the forms have been formed, and the drying process then takes place.
  • the filling compound ensures that the characteristics are retained even when the embossed wallpaper is processed further. This also results in a safe filling of the cavities, since the cavities are filled to the brim with the filling compound by brushing into the wet carrier layer and slight shrinking of the carrier layer during the drying process.
  • the carrier layer is first dried and then the filler is applied to the back and then completely dried.
  • the filler is applied to the back and then completely dried.
  • the carrier layer it is possible to make the carrier layer relatively light in weight, since the forms obtain a certain stability as a result of the drying, and can thus absorb the filling compound without deformation. It is particularly cheap.
  • the filler compound sets in order to securely connect the filler compound to the carrier layer.
  • the embossed wallpaper 10 is constructed from a single carrier layer 11, which consists of either duplex or simplex paper. On its front there are features 12 which form cavities 13 on the back.
  • cavities are filled with a filling compound 14 in such a way that either a layer of the filling compound extends over the entire rear side of the carrier layer 11, or else. that the webs 15 provided between the features 12 can still be seen on the back of the carrier layer.
  • the imprint wallpaper consists of either embossed paper or an embossed mineral nonwoven.
  • the filling compound is made up of a binder and a filler, each consisting of environmentally friendly substances.
  • the binder is made of natural rubber. It can also be natural resin. Tree resin, rosin, beeswax, casein, copal resin or starch can be used, mixtures of these substances can also be put together as binders.
  • the binder is provided with hydrophobic binding agents in order to ensure an intimate connection between the carrier layer and the filling compound as long as the binder has not yet hardened. While later, when wallpapering with the embossed wallpaper, the binding forces between the embossed wallpaper and the wall to be wallpapered, due to the lower absorption of the water-soluble wallpaper paste. are smaller than between the filling compound and the carrier layer.
  • Kaolin, gypsum, talc, wood flour, chalk are provided as fillers. Various mixtures of these substances can also be used here.
  • the filler in the filler is used in a higher proportion than the binder.
  • a proportion of 60% filler and 40% binder is preferably used for the filling compound.
  • the filling compound is introduced into the cavities 13 as a natural mechanical foam. This measure creates capillaries in the filling compound, through which the natural breathability of the paper embossed wallpaper is maintained.
  • a carrier layer 11 made of simplex paper is guided between two guide rollers 17 to a soaking device 18 and from there is guided via guide rollers 19 to the actual steel embossing rollers 20.
  • the wallpaper web is passed via a first drying stage 21 to a station 22, in which the foam-like filling compound from a container 23 is fed into the cavities 13 on the back via an applicator 24.
  • a further drying stage 25 is provided behind the station 22. In this drying stage, the filling compound located in the cavities is also set, so that after the drying stage the embossed wallpaper can be packed and shipped.
  • the embossed wallpaper 16 is produced from a carrier layer 11 consisting of top and bottom paper.
  • the top and bottom paper is put together in a soaking and laminating station. Then, via a soaking section 27, in which the carrier layer is arranged in folds, to the paper embossing roller 28 and the steel embossing roller 29.
  • An applicator 24 is provided directly behind the roller 29 for applying the filling compound to the back of the carrier layer.
  • the carrier layer provided with the filling compound then passes into a first drying stage 21. After this stage, if desired, a second application device 24 is provided in order to apply a supplementary layer of the filling compound to the carrier layer. Finally, the final drying takes place in the second drying stage 25.
  • the filling compound also sets in the carrier layer.
  • the illustrated embodiment is only one example of realizing the invention. This is not limited to this. Rather, various changes and applications are still possible.
  • the filling compound can also be made of synthetic materials, and the carrier layer itself could also be made of plastic. It should also be mentioned that the carrier layer and the embossing can be introduced into the cavities directly after the stampings have been produced. only then does the drying and possibly also vulcanization of the filling compound, including the wallpaper, take place.
