Definitions

  • the invention relates to a fully weldable floor covering for wet rooms and exterior surfaces.
  • the floor covering reliably seals the covered base area from external influences and thus eliminates the need for additional insulation work.
  • More or less thick bitumen layers are also used as a primer, onto which thick foam boards, e.g. made of polystyrene.
  • thick foam boards e.g. made of polystyrene.
  • Wear-resistant thin floor coverings e.g. not laid out of rubber easily. It is known that rubber is water- and weather-resistant, but in parallel with this desired inert behavior there is the property of repelling glue, so that rubber plates show little adhesion to conventional primers. The adhesion achieved is generally not sufficient to securely hold a wear layer. In addition, such laying must take place in wet and outdoor areas, where the choice of the latter is very limited due to the risk of hydrolysis of the adhesives. The laying is therefore very complex and expensive.
  • a conventional rubber covering is e.g. in CH-A-424186.
  • the three-layer rubber sheets are suitable for damp and outdoor spaces and are also resistant to abrasion, but they require careful preparation and insulation of the substrate, which is usually made of bitumen or concrete. Despite the usual precautionary measures, water damage is to be expected, especially when lying outside for long periods and when there are major temperature fluctuations.
  • the object of the invention is now to develop a combined sealing and walking surface which is absolutely reliable against moisture, which, for reasons of space, may only have a smaller thickness and which is mechanically resistant, i.e. wear-resistant.
  • the walking surface should be made of rubber.
  • An economical process for laying such a covering is still sought.
  • the invention uses a continuous water- and weather-resistant covering made of multilayer synthetic or thermally or source-welded foils. It is a multi-layer elastomeric material, the sheets of which are tightly welded together at their overlapping edges. After installation, post-vulcanization usually takes place due to weather conditions. Without the use of conventional adhesives, a walk-on rubber covering is also applied to this continuous primer from the film material mentioned, also by swelling.
  • This covering is made of synthetic rubber and contains a vulcanization accelerator, which, however, is preferably on the upper, i.e. the walking side is located. The lower side of the walking surface facing the primer is free of vulcanization accelerators.
  • the floor covering like the primer, vulcanizes after laying so that a particularly firm and resistant bond occurs. All layers, i.e. Both the primer and the walking surface are connected and solidified by vulcanization.
  • the synthetic rubber sheets or sheets provided as walking coverings are produced by vulcanization in a vulcanizing machine or in a press.
  • the vulcanization skin of the upper layer also represents the wear-resistant walking layer. It has already been mentioned that such rubber coverings are usually applied to leveled screeds with adhesives. To do this, the surface must be very even and there are major problems with the adhesive. With the floor covering according to the invention, on the other hand, it is possible to apply the rubber plates directly on the primer without adhesive. Regardless of temperature influences, there is always tight, robust insulation. Depending on the requirements, a usable rubber covering can be selected, which is firmly connected to the appropriate primer by swelling.
  • the multi-layer film material for the primer is laid over the entire surface, e.g. brought to the construction site in roll form and glued directly to the leveled screed.
  • the walking surface is then applied by source welding.
  • the floor covering according to the invention is absolutely waterproof, there is no need to use adhesives as a foreign layer and thus the risk of hydrolysis due to the action of water, which is always present with conventional coverings.
  • the overall height is very low and is only determined by the thickness of the primer and the walking surface. There is a firm bond between the floor covering and the primer. This connection is waterproof. It is created by the merging of surface parts of the primer and the walking surface.
  • the covering is made entirely of synthetic rubber and therefore has sufficient elasticity that can compensate for movements of the surface.
  • the layer of the multilayered elastomeric material provided as a primer for the walking covering is constructed such that a vulcanizable inner layer consisting of one or more foils containing vulcanization accelerators is initially provided.
  • This inner layer is separated by at least two, i.e. provide an upper and a lower cover layer made of vulcanization accelerator-free but also vulcanizable materials.
  • These layers are firmly bonded together, e.g. in a press or a vulcanizing machine.
  • the mixtures are expediently adjusted so that the outer layers not provided with vulcanization accelerators are included in the accelerator portion of the inner layer and are therefore chemically bonded to the inner layer.
  • the multilayer structure constructed in this way can also be used at higher temperatures, e.g. resistant at 80 to 100 ° C. A separation of the layers is therefore not to be feared even under extreme stress.
  • the inner layer containing the vulcanization accelerator By means of a suitable composition or equipment of at least one of the layers connected to one another, expediently the inner layer containing the vulcanization accelerator, the multilayer structure is able to, e.g. after vulcanization on an outer surface, due to weather influences.
  • the properties are essentially determined by the elastic, vulcanizable inner layer containing the vulcanization accelerator.
  • the multilayer structure is also elastic and shows no cold flow.
  • the usage properties are improved to a very considerable extent, particularly in the case of "working" buildings and on uneven surfaces.
  • Post-vulcanization has a particularly favorable effect on the sensitive seams. This results in absolute tightness even under the most unfavorable conditions.
  • a wear-resistant synthetic rubber floor covering is applied without adhesive to the multi-layer primer thus constructed.
  • SBR styrene butadiene rubber
  • other wear-resistant types of rubber e.g. NBR (nitrile butadiene rubber), CR (chlorine rubber), EPDM (ethylene propylene terpolymer) or the like.
  • the walking surface consists of multi-layer panels or sheets of this material.
  • the layer of the walking surface facing the primer is free of vulcanization accelerators, while the walking surface contains a vulcanization accelerator.
  • the plates can e.g. contain a walking surface made of SBR and a lower layer made of EPDM rubber.
  • the vulcanizable SBR and the non-vulcanizable EPDM layer form a homogeneous connection with one another and despite the transition of accelerators from the SBR layer into the EpDM layer, the latter can still be source-welded.
  • the sealing layer is created with the sealing membrane provided as a primer, which is also source welded from membrane to membrane. This layer expediently contains a lamination made of nonwoven material or another textile material or of glass fibers.
  • the substrate can consist of stone, cement, wood, plastic, bitumen or the like.
  • the floor covering is attached to the primer by swelling with suitable solvents, suitably based on perchlorethylene.
  • suitable solvents suitably based on perchlorethylene.
  • the sealing membrane provided as a primer can be used at normal temperatures, e.g. up to 25 ° C, can be stored indefinitely.
  • the material is also resistant to short-term higher temperatures, such as those that can occur during transport.
  • the properties are not changed, i.e. the covering remains weldable.
  • the primer consists of several interconnected layers of EPDM material, the inner layer or the inner layers made of EPDM material and the outer layers made of a vulcanizable blend of EPM (ethylene-propylene copolymer) and EPDM material can exist.
  • the priming with the panels or sheets of the floor covering attached by swelling has proven itself in which the covering sheets are first arranged in an overlapping manner next to one another and the overlapping areas then with the solvent or swelling agent or a mixture of these substances, which can optionally contain a vulcanization accelerator , are provided.
  • the webs of the covering are then welded to form a dense, mechanically and thermally resistant skin. Then the walking surface is also applied by swelling. This results in a minimal effort for the publisher.
  • the following example shows a weldable floor covering constructed according to the invention.
  • Sheets of the composition described above are laid overlapping on the correspondingly prepared leveled screed, wherein a layer of non-woven material, which is connected to the sheet material by lamination, can be applied between the screed and the sheet.
  • the covering is connected to the screed using hot bitumen, cold bitumen adhesive or other waterproof adhesives.
  • the overlapping edges of the webs are source welded using a solvent based on perchlorethylene.
  • a walking surface in the form of a plate or sheet is then welded on as a wear-resistant layer using the same solvents.
  • the covering or the plates can be provided with pastilles or other elevations.
  • the layer based on SBR rubber or NBR, CR, EPDM or the like is drawn to a thickness of 2 to 5 mm with the aid of a calender.
  • the second layer based on the EPDM-based recipe above is also drawn with a calender to a thickness of 1 to 3 mm. Both layers are placed on top of each other so that the EPDM layer comes down. Both layers are pressed in a multi-stage press at 170 ° C for 8 to 9 minutes. The pressure is 140-200 bar.
  • the vulcanizable SBR and the non-vulcanizable EPDM layer are homogeneously connected to each other and despite the transition of accelerators from the SBR layer to the EPDM layer, it is still weldable.
  • the multilayer structure is hot-demolded from the press.
  • the floor covering is easily weld-welded to the sealing membrane provided as a primer using a solvent based on perchlorethylene. This source welding takes place at the construction site. The result is a wear-resistant, extremely robust, sealing floor covering that can also withstand heavy loads in the outside area.
