Definitions
- the invention relates to a diffusion-open underlay membrane for lamination by adhesive to one Insulating body, in particular for the formation of an insulating board for Aufsparrendämmung, with a particular as Spunbonded carrier and a permanently attached, waterproof but water vapor permeable membrane, according to the preamble of claim 2 and a Process for their preparation according to claim 1.
- Such vapor-open underlays are in State of the art by means of liquid, for example.
- Water-dilutable Gluing in the casting order on the insulating body laminated see DE-A 43 22 745, DE-U-295 08 123, DE-A-860 13670 or DE-A-36 15 109
- Disadvantage of this method is a necessary Interim storage before packaging for the purpose the ventilation of the water or solvent components.
- One Another disadvantage is the self-adhesive changing diffusion values.
- the edge-protruding Strip of the underlay which at laid insulation boards in Matterlapptlage occur to the adjacent insulation board, by means of adhesive tape or other adhesives are connected there.
- the invention is based on the object, a diffusion-open Further develop underlay membrane such that on the one hand, the production of an insulating board, in particular for a Aufsparrendämmplatte, and also the laying such a manufactured insulating board is simplified.
- the adhesive applied to the Unterspannbahn Hot melt adhesive in the form of a hot melt nonwoven is.
- the application of the Hot melt adhesive can be used in one production separate process step done. customarily be the carrier forming spunbonded and the waterproof but water vapor permeable membrane each unwound from a supply roll and in a special laminating machine, for example a flat bed laminating machine, connected with each other. Immediately after This lamination is done with the coating Hot glue.
- the hot glue can be meltblown Hot melt nonwoven be applied, this by Inflate directly to the bottom of the vapor-permeable Underlay can be made.
- a web structure consisting of a membrane made of polyethylene, which is coated on one side with a UV-stabilized polypropylene spunbonded nonwoven and on the other hand the inflated hot melt adhesive layer, which is formed in the form of a nonwoven.
- a insulation mat that made a Dämmharm in particular made of hard foam can on its roof outside surface be laminated with a vapor-open underlay membrane.
- the lamination the underlayment on the insulation board only by temperature and possibly additional pressure, e.g. by means of an infrared radiator and a pinch roller. But they are also suitable in particular flatbed laminating systems.
- Advantageous is when the finished insulation board over the Edge extending strip which with a hot glue laminated roofing membrane is formed. This overlap strip can then by heat application connected to the lamination of an adjacent insulation board become.
- the illustrated underlayment consists of a spunbonded fabric lying on its outwardly facing side.
- This spunbonded web can be a 80 g / m 2 polypropylene spunbonded web.
- This spunbonded nonwoven 2 is fixedly connected to a membrane 3, which may have a basis weight of 32 g / m 2 and consists of a polyethylene film, which is waterproof but permeable to water vapor.
- a membrane 3 which may have a basis weight of 32 g / m 2 and consists of a polyethylene film, which is waterproof but permeable to water vapor.
- polypropylene for example in the form of a melt-blown nonwoven.
- the melt-blown nonwoven is waterproofed by applying heat and the resulting entanglement. The resulting pores ensure that this film is permeable to water vapor.
- the membrane 3 is provided with an adhesive layer 4 in the manufacture of the underlayment.
- This is a heat activatable adhesive.
- This layer 4 is formed by a melt-blown hot-melt adhesive web which is inflated directly onto the underside of the vapor-permeable underlay web.
- polymers for forming such a hot-melt adhesive film 4 are suitable materials such as EVA, PUR, PA and PP.
- the weight per unit area of this hot-melt adhesive is preferably between 5 and 20 g / m 2 .
- the insulating body 5 is preferably made a hard plastic made of polystyrene or polyurethane. Also, this plastic body can be pre-assembled become. He has in particular an edge profiling, around a rebated with a neighboring plate Train fugue.
- the roof underlay is on the Insulating body 5 laminated in such a way that a side strip 6 over the fold to the adjacent insulation board. This side strip 6 can also by heat application, eg. By means of a hot air blower, on the roof underlay 1 of an adjacent lying Insulating board to be glued.
- the ereuerlelie insulation board is preferably in used for rafter insulation, it becomes instantaneous applied externally to the formwork. On the outside facing underlayment 1 is then the counter battens and the battens on which the roof tiles be applied.
