Definitions

  • the present invention relates to a bitumen sheet composed of a carrier insert and bitumen or polymer bitumen, which is provided with a covering layer made of a light and thin nonwoven.
  • Bitumen membranes made from a carrier insert and bitumen or polymer bitumen as adhesive or welding membrane are e.g. widely used to seal roofs and other structures. They consist of a carrier insert, e.g. impregnated with bitumen and mostly coated on both sides.
  • the top of the bitumen membrane is sprinkled with talc, sand, slate or similar materials or provided with a film.
  • the underside is provided with a release medium to ensure that the rolls can be unwound properly.
  • Talcum or sand are also frequently used here.
  • these separation media have the disadvantage that they can affect the firm connection of the web to the roof when laying the bitumen sheet after the welding process. This can lead to blistering and ultimately to leaks.
  • bitumen sheets with a cover film on one or both sides, preferably on the underside, in order to be able to better wind them up into rolls or to pull them off the rolls again.
  • the cover sheet like the particle scattering, is intended to prevent the layers of the rolled-up bitumen membrane from sticking together.
  • a serious disadvantage of these bitumen sheets provided with covering foils is that the fastening of the sheet on the surface to be covered is made more difficult and its adhesion to the base can also be deteriorated.
  • Bitumen sheets are either glued to the underlay using hot bitumen or solvent-containing cold-glue bitumen, or welded on using a flame.
  • the covering foil can be removed before welding, or melted away by contact with the hot flame.
  • this increases the time and effort required to lay the train.
  • bitumen sheets using the bitumen adhesive process is much faster than using the welding process. Occasionally, therefore, an attempt has been made to lay a welding sheet laminated on the underside with hot adhesive bitumen. Due to the thin adhesive bitumen layer, the film is often not melted or only incompletely. The film then prevents complete adhesion and acts as a separating layer.
  • bitumen sheets can be glued with cold or hot glue bitumen, but the direct adhesion between top layer bitumen and adhesive bitumen remains limited to the film-free holes on the back of the sheet.
  • bitumen sheets which are provided on one side with a mat of up to 30 mm thick made of elastic non-woven wires, threads or fibers.
  • This mat has a solids volume of approx. 2% and serves as an air-containing spacer between the bitumen membrane and the Document.
  • air space formed in this way relative movements between the bitumen sheet and the base are to be compensated and gas exchange processes are to be made possible.
  • An essential moment when using this known bitumen sheet is that the air volume enclosed in the mat must be preserved when the sheet is applied. There are therefore also considerable fastening problems here. For example, it is not recommended to glue the entire surface of this membrane to the base, as this would negate the intended effects.
  • bitumen sheets which are provided on one or both sides with a thin covering layer made of a nonwoven fabric, are surprisingly wound into firm rolls without the risk of layer bonding and, according to all known laying methods using bitumen, quickly, without complications and permanently can attach the pad.
  • the present invention thus relates to a bituminized roofing and waterproofing membrane with a covering layer made of a nonwoven fabric, which is characterized in that a covering nonwoven fabric with a basis weight of 10 to 80 g / m2, preferably 10 to 40 g / m2, on one or both sides of the bituminized sheet. m2, in particular 10 to 20 g / m2 is laminated.
  • the covering nonwoven is preferably applied on one side, namely on the underside of the bitumen sheet facing the base, while the top of the sheet is usually sprinkled with mineral material.
  • the cover nonwoven can also be used advantageously to cover the overlap edges.
  • Both non-woven and continuous fibers are suitable as cover nonwoven, the latter being preferred.
  • Fiber-forming polymers or polycondensates are used as the material for the production of the cover nonwovens.
  • Polymers such as. B. polyethylene, polypropylene or polycondensates such as polyamide and especially polyester.
  • the fleece covering of the bitumen sheets according to the invention brings a combination of advantages which have an effect both in the storage and in the subsequent laying of the bitumen sheets.
  • the bitumen membrane according to the invention can not only be protected against layer adhesion during storage, but it can also be optimally adapted to the planned type of installation.
  • the melting point of the fleece-forming fiber material is of particular importance here.
  • bitumen membrane is to be laid using the welding process, ie with an open flame, then it is advisable to use a covering nonwoven with a relatively low melting point. It is therefore expedient to choose a fleece from a raw material for covering welding webs, the melting point of which is equal to or slightly lower, preferably somewhat lower than that of the carrier fleece of the bitumen web.
  • a very cheap combination of this type is e.g. B. the use of a carrier fleece made of polyethylene terephthalate and a cover fleece made of polybutylene terephthalate. Preference is also given to nonwovens which have a high area coverage with a relatively low basis weight.
  • such a cover fleece is calendered before use, which can be carried out in particular as part of the consolidation, since calendered nonwovens have a less hairy surface than e.g. B. needled.
  • Nonwovens made with smooth calenders solidify, show a particularly high area coverage and are therefore preferred.
  • Even fine titers increase the area coverage of the cover fleece and are therefore preferred.
  • B a bitumen modified with atactic polypropylene (APP).
  • the very heat-resistant plastic bitumen is not melted sufficiently by the adhesive bitumen, which is approx. 200 ° C, during laying to liquefy the surface of the plastic bitumen sheet and to enable an intimate connection of the two types of bitumen.
  • nonwoven with a basis weight in the middle part of the above range of 10 - 80 g / m2, d. H. preferably with a basis weight of 30 - 60 g / m2.
  • nonwoven material that does not melt too low because the fleece is in contact with should not melt away the hot adhesive bitumen, but must act as an adhesion promoter between adhesive and polymer bitumen.
  • the melting point of the covering nonwoven should therefore be in the range from above to somewhat below the melting point of the carrier insert.
  • a fleece for this purpose with a large specific surface area, such as the non-calendered non-woven fleece which is consolidated by needles.
  • Needled nonwovens made from a raw material that has approximately the same melting point as the carrier fleece are therefore particularly preferred for coating polymer bitumen webs that are to be laid using the bitumen adhesive process.
  • a cost-effective way to meet this requirement is to use the same raw material for the non-woven backing of the bitumen membrane and for the covering fleece. It is advantageous for. B. the use of the same polymer material, e.g. B. of polyethylene terephthalate for both nonwovens.
  • bitumen sheets according to the invention are those which combine several preferred or favorable features.
  • the figure shows a section through an embodiment of the bituminized roofing and waterproofing membrane according to the invention composed of a bitumen-soaked carrier insert (1) with upper and lower bitumen coatings (2) and a light covering fleece (3) laminated on one side with a high area coverage.
  • a bitumen sheet according to the invention in which at least one surface (side) is laminated with a covering fleece, can be produced by bringing together the freshly produced, warm and therefore still sticky bitumen sheet and a suitable covering fleece, if necessary with brief pressure.
  • the covering fleece allows a perfect laying both after the welding as well as the different bitumen-based adhesive processes without having a separating effect in the processed state.
  • the covering fleece applied according to the invention melts; during spot welding, it only melts at the welding points, the remaining surface of the covering fleece then still acts as additional reinforcement.
  • the cover fleece also acts as additional reinforcement when laying according to the bitumen adhesive process and thus improves the mechanical and technical properties of the entire waterproofing structure. It is a particular advantage that the adhesive bitumen soaks the covering fleece slightly and that a perfect full-surface bond between the bitumen sheet and the base is made possible.
