Definitions

  • the present invention relates to a plastic sheet which prevents or at least substantially reduces water vapor diffusion, a method for producing this plastic sheet and its use.
  • the high vapor diffusion resistance is generated by polyethylene, aluminum, bitumen or a wax layer.
  • Vapor barriers based on blown polyethylene films have the disadvantage of a high expansion coefficient. This results in large thermal movements, which lead to various problems.
  • the lamination of a polyester mesh fabric between two polyethylene films did not lead to the final solution to the problems.
  • Aluminum vapor barriers regardless of whether they are pure aluminum foils, composite foils with plastic coating or laminates with kraft paper, have the disadvantage that connections and closings in penetrations and on the roof edge are difficult to carry out due to the minimal elasticity.
  • the products are opaque and have a smooth, relatively slippery surface. Ecological considerations regarding composite materials of aluminum with other substances are also appropriate, since recycling is hardly possible.
  • Vapor barriers and vapor barriers based on bitumen have similar disadvantages as aluminum vapor barriers. Here, too, connections and terminations are generally difficult to implement. There are also reservations about ecological safety.
  • This new plastic sheet should also be combined as desired and connected by gluing or welding with a plastic sealing sheet, as described for example in European Patent No. 0 428 851 B1, or with a porous plastic sheet based on polyolefins, as described for example in a simultaneously filed and a priority date (April 19, 1994) Swiss patent application entitled "Plastic Railway" is defined.
  • This plastic sheet should preferably also be translucent.
  • This plastic web should be built on the basis of inexpensive raw materials and should be able to be manufactured using inexpensive processes.
  • This new plastic sheet should also be able to be fixed to plate-shaped materials which serve for thermal insulation and / or sound insulation and / or fire protection.
  • the raw materials should be selected such that the plastic sheet produced therefrom can be recycled, in particular together with the above-mentioned plastic sealing sheet and the above-mentioned porous plastic sheet.
  • This new plastic sheet should preferably be based on polyolefins and in particular should have a smaller expansion coefficient than conventional blown polyolefin films.
  • the plastic sheets according to the invention fulfill the above objectives.
  • the plastic webs according to the invention have, among other things, the enormously important advantage that they have an expansion coefficient that is at least about 50% smaller than conventional blown polyolefin films.
  • the plastic sheets according to the invention can have a non-slip surface.
  • the plastic sheets according to the invention contain no halogens, no polyvinyl chloride, no bitumen, no heavy metals, such as lead and cadmium, and no metallic aluminum.
  • the web is recyclable. Disposal by incineration or landfill is harmless.
  • the plastic sheets according to the invention are ecologically harmless.
  • the plastic sheet according to the invention is preferably translucent (translucent).
  • the plastic web according to the invention can be processed in various ways.
  • the plastic webs according to the invention can be connected to one another with suitable adhesive tapes or adhesive compositions, for example made of polyisobutylene. But you can also use Hot air or hot wedge devices are welded to one another mechanically or by hand.
  • the manufacturing method according to the invention makes it possible to produce a product with excellent properties from cheap raw materials. This results in a good price / performance ratio.
  • the manufacturing method according to the invention enables the application of hot melt adhesives to the plastic web in the simplest way.
  • the lamination of the web, e.g. elements are machine-prefabricated on thermal insulation boards, which already contain several functional layers and can be installed very efficiently.
  • the plastic sheets according to the invention are preferably used as vapor barriers or vapor barriers.
  • FIG. 1 through 8 show sections through typical roof structures in which plastic sheets according to the invention are used.
  • plastic sheets according to the invention are used as individual layers.
  • the plastic webs according to the invention are fixed to a plate-shaped material (composite elements).
  • the procedure for producing a 0.55 mm thick plastic sheet coated on one side was as follows: The linear low density polyethylene powder "Coathylene" R LL 1161 from Plast-Labor SA in CH-1630 Bulle / Switzerland was sprinkled onto a glass fleece running at a speed of 0.49 m / min with a basis weight of 50 g / m2 .
  • the order quantity was 460 g / m2.
  • the product thus obtained was heated in a 0.6 m long oven by means of infrared radiation from above to a temperature of a maximum of 192 ° C.
  • This temperature was measured on the product surface using a temperature sensor.
  • the product thus obtained was passed under pressure through a calender with two water-cooled steel rollers.
  • This product was passed around a chill roll and wound up.
  • the plastic sheet produced in this way had the following properties: exam standard value Permeability to water vapor ASTM E 398-83 (38 ° C, 90%) 0.19 g / m2 24 h tensile strenght DIN 53455 13.1 N / mm2 Elongation at break DIN 53455 145%.
