Definitions

• the invention relates to the use of a double-sided adhesive tape for residue-free and damage-free removal of a glued floor covering like a carpet or an elastic flooring.
• the present invention presents a new system with which a complete reversible and residue-free fastening of flat or cut Flooring is reached. Product structure and fields of application of the novel Fixing systems for floor coverings are described.
• Double sided Self-adhesive tapes can with sufficient original adhesion poorly or with damage to the floor covering or the subsurface be replaced again. It also happens with certain recipes before that the pressure sensitive adhesive returns to its original state due to environmental influences and / or aging Loses shape and degenerates into a syrup or a brittle structure. He is no longer up to his function. After the removal of the glued floor covering remain more or less difficult to remove Adhesive residue on the surface. The underground must therefore subsequently cleaned of adhesive and adhering floor covering residues. Cleaning is often difficult, time-consuming and expensive. When removing the glued floor covering from the surface furthermore there is a risk that parts of the surface of the floor, such as Wooden parts from parquet or laminate floors can be removed. PVC or CV substrates can be discolored by solvents.
• the object of the invention is a practical and inexpensive method to be made available through the flat or cut floor coverings fixed quickly and conveniently and yet residue-free at any time can be easily removed.
• DIN 61 151 provides an overview of various types of carpets (knitted and knitted carpets, tufted carpets, woven carpets, needle fleece coverings, etc.) and the different carpet backing equipment (latex foam in different variants, synthetic backs, jute backs, polyurethane foam backs, etc.).
• substrates are:
• Carpet tapes can usually not be removed without residue. Adhesive residue need to be removed with great effort after removing the flooring will. The removal is done mechanically (e.g. spatula, sanding the Parquet) or by solvents. The former method can cause damage of the subsurface, the latter method shows health Dangers and safety risks (explosion hazard, fire hazard).
• Double-sided PSA tapes / self-adhesive systems that have a different Have adhesiveness and are therefore resumable.
• Self-adhesive tape with a gap-proof carrier (support fabric) with double-sided adhesive coating The side facing the underground has a smaller one Adhesion on as the side facing the flooring. Lies to the bottom an adhesion of less than 850 p / 25 mm. This should make it possible the floor covering together with the adhesive tape, again from the floor to solve.
• Self-adhesive tape for flooring characterized in that the absolute adhesive surface one side is larger than the adhesive surface of the other side.
• a reduction the absolute adhesive surface is e.g. through a strip-like coating achieved with adhesive.
• Another way is to partially cover the Adhesive with a non-sticky tape, which is provided with openings.
• a mesh or knitted fabric is with a pressure sensitive adhesive System impregnated.
• Adhesive nonwovens or adhesive grids that are coated with a weakly adhesive system e.g. on Basis of dispersion acrylates. Due to the relatively low liability a residue-free removal should be ensured.
• TacFast TM Carpet System US 4,822,658, US 5,191,692
• a floor covering is fixed between a self-adhesive one Hook tape and the specially equipped and reinforced floor covering back.
• the fleece equipment is part of the back of the floor covering.
• the hook straps can on the Remain underground while the worn floor coverings are simply replaced can be.
• Velcro systems can also be used to fasten flooring elements in motor vehicles (eg EP 0 594 925 B1 ).
• a carpet fixation takes place between the substrate (filler with incorporated Iron powder) and the back of the flooring by magnetic attraction.
• the back coating of the floor covering consisting of bitumen, Latex, PVC or textile backing becomes permanent as a binder / filler magnetizable material (e.g. ferrite) incorporated.
• the back of the flooring can also be equipped with a self-adhesive magnetic film.
• Assembled systems as described in DE 44 28 587, are particularly suitable for suitable for sensitive surfaces. With a shaped tip, the occurring strip forces can be significantly reduced.
• Assembled systems as described in DE 43 39 604, are particularly suitable for suitable for small, tailored floor coverings. Due to the special assembly the floor covering can be easily removed by pulling it.
• stripable systems are particularly suitable for certain floor covering fixings suitable.
• Stripable systems with acrylic top layers are characterized by a high Resistance to plasticizers. Such systems are special suitable for PVC and CV floor coverings and / or substrates.
• the layer of adhesive preferably has a low Shore hardness (Shore A 10 ⁇ 3) to easily adapt to the back structure.
• a fixation system should consist of aesthetic and safety-related Do not mark reasons (tripping hazard) under the floor covering.
• the total thickness of the strippable system should therefore be less than 1000 ⁇ m, better below 750 ⁇ m, ideally below 500 ⁇ m.
• the surface must comply with the technical rules of DIN 18365 ( The surface must be dry, firm, free of oils, waxes and release agents. Uneven surfaces must be leveled out before laying, eg by filling.
• the carpet fixing die cuts are placed on the floor at the required distance glued and manually pressed on carefully. The required distance depends from the back structure of the flooring.
• For floor coverings with a textured back (high-quality foam backing, PVC / CV coverings, high quality textile backing) can be a suitable distance between 1.00 m and 2.50 m.
• Floor coverings that do not have a solid back structure should be at a distance of between 0.5 m and 1.50 m can be glued.
• the stripable installation tape follows the contours of the room in the edge area of the floor covering glued to the surface and pressed on well. Of the The floor covering is rolled out, roughly cut and then folded back. The siliconized protective paper is removed from the tape. The floor covering is then firmly attached to the floor with a slight tension Tape pressed on. Finally, the edges are cut cleanly.
• Roll goods thickness 480 ⁇ m, width 35 mm.
• Laying with rolled goods is particularly suitable for gluing Carpets in less frequented rooms, e.g. Bedroom or guest room.
• Diecuts thickness 480 ⁇ m, 30 mm x 65 mm (width x length). At one end there is a non-sticky handle measuring 30 mm x 12 mm. The handle area is obtained by laminating 12 ⁇ m thick PET film on both sides.
• the diecut also has a shaped end (DE 44 28 587, EP 696 628), so that the adhesive surface decreases at the end of the adhesive film strip. advantages for the stripping process result as described in DE 44 28 587.
• Laying with die cuts is particularly suitable for gluing Carpets in high-traffic areas, e.g. Corridors, children's rooms or areas with chair castor load like desks.
• Example 1 The advantages mentioned in Example 1 also apply to the possible application areas of die cuts and rolls.
• Roll goods thickness 470 ⁇ m, width 28 mm.
• Die cut A thickness 555 ⁇ m, 30 mm x 65 mm (width x length). At one end there is a non-sticky handle measuring 30 mm x 12 mm. The handle area is obtained by laminating 12 ⁇ m thick PET film on both sides.
• Die cut B thickness 555 ⁇ m, 30 mm x 250 mm (width x length). At one end there is a non-sticky handle measuring 30 mm x 12 mm. The handle area is obtained by laminating 12 ⁇ m thick PET film on both sides.
• Removal of the floor covering after several months of testing was carried out as follows: The tufted flooring with textile backing was rolled up to the first row of die cuts.
• Stripable multi-layer systems are particularly suitable for gluing floor coverings suitable with textile back structure.
• a very soft adhesive layer with high adhesive strength (low elasticity and high plasticity) which is ideal for rough surface structures, such as textile carpets is suitable with an optimally stripable adhesive layer (high Elasticity and low plasticity) can be combined.
• Die cut A thickness 570 ⁇ m, 30 mm x 65 mm (width x length). At one end there is a non-sticky handle measuring 30 mm x 12 mm. The handle area is obtained by laminating 12 ⁇ m thick PET film on both sides.
