Definitions
- the invention relates to a composite profile according to the preamble of claim 1.
- the second adhesive layer consists of PU hot melt or ethylene-vinyl acetate copolymer (EVA) or polyamide (PA). This second layer of adhesive is not yet optimal in all applications.
- a composite material is known per se from DE 195 47 720 C2.
- a base body with recovered PE / PP blend is co-extruded with a layer of pure PP.
- the free surface of the PP layer is physically pretreated and then provided with a layer of solvent-free primer and dried.
- a layer of moisture-curing PUR hot-melt adhesive is applied to the dry primer layer or a decorative film.
- the entire composite material is allowed to cool under pressure and then the hot melt adhesive is cured in 1 to 7 days with atmospheric moisture.
- a hot-melt adhesive hardened in this way would not be suitable for the purposes of the composite sealing profile according to the application and would be too complex to produce.
- a known composite profile (EP 0 320 676 A2, embodiment 3) has a 1 mm thick PVC foam layer, which is film-coated on one side with an extruder with 20 g / m2 of polyethylene. The other side of the foam is coated with a polyacrylate adhesive and covered with a siliconized protective paper.
- This assembly tape is laminated to an EPDM profile with its polyethylene film under pressure and heat. After the protective paper has been removed, the self-adhesive EPDM profile can be glued to a painted motor vehicle door frame, for example. There is a risk that the polyethylene film will become plastic again at elevated temperature and the EPDM profile will become detached from its adhesive tape. This is especially true for the composite profiles of open doors, trunk lids and sunroofs and when repainting motor vehicles.
- the invention has for its object to expand the application and application of such composite profiles.
- Such a reactive hot melt adhesive can be applied directly to one of the materials to be bonded, for example by means of an application gun, and can be joined to the other material immediately thereafter. After the applied adhesive has cooled, the adhesive connection already has a very high initial strength. The significantly higher final strength (adhesion, heat and cold resistance) is achieved in a few days, depending on the type of adhesive. According to claim 2, quite thin second adhesive layers are sufficient for a firm adhesive connection.
- primer layers are always used when dealing with relatively low-energy surfaces to be bonded. In these cases, too, the primer layers can achieve a very strong adhesive bond.
- the carrier layer consisting of foam is used in particular to compensate for unevenness, such as sheet metal doubles, dents or welding spots, in the body of a motor vehicle or to lay the composite profile around relatively narrow radii of the body.
- Sealing profiles according to claim 8 are used e.g. in body construction for sealing doors, trunk and lights, in building construction for door and window seals and as seals for control cabinets.
- the design of the counter surface according to claim 10 can, if necessary, simplify and improve the adhesion of the sealing profile to the carrier layer. ser.
- the counter surface can be prepared, for example, by mechanical roughening or by corona discharge or by means of a firing shoe (oxidation of the counter surface) or by plasma treatment.
- 1 to 4 each schematically the layer structure of different embodiments of a composite profile made of an adhesive tape and a sealing profile.
- FIG. 1 shows a composite profile 1 made of an adhesive tape 2 and a sealing profile 3 made of EPDM.
- the adhesive tape 2 has a carrier layer 4 made of a foam, e.g. a PU foam on.
- An acrylate adhesive which is covered by a liner 7, is applied to a first surface 5 of the carrier layer 4 as a first adhesive layer 6.
- the liner 7 is pulled off the first adhesive layer 6 and the composite profile 1 with the first adhesive layer 6 is pressed onto the counter surface of the body.
- a second surface 8 of the carrier layer opposite the first surface 5 is glued to a counter surface 9 of the sealing profile 3 by a second adhesive layer 10.
- the second adhesive layer 10 is a cross-linked reactive hot melt adhesive of comparatively high temperature resistance.
- a first primer layer 11 is arranged between the carrier layer 4 and the second adhesive layer 10. In this way, the bond between the carrier layer 4 and the second adhesive layer 10 can be improved if necessary.
- a second primer layer 12 is arranged between the second adhesive layer 10 and the counter surface 9 of the sealing profile 3. In this case, the bond between the second adhesive layer 10 and the sealing profile 3 can be improved if necessary.
- the exemplary embodiment according to FIG. 4 is provided with the first primer layer 11 between the carrier layer 4 and the second adhesive layer 10 and with the second primer layer 12 between the second adhesive layer 10 and the sealing profile 3. This also makes it possible to achieve the desired adhesive connection in the composite profile 1 if required in any practical application.
