Definitions

  • the invention relates to a hollow chamber profile made of thermoplastic material and its use for windows and doors.
  • thermoplastic material are widely used for the production of plastic windows and plastic doors. These profiles are predominantly made by extrusion from rigid PVC (PVC-U). They usually have several hollow chambers, which are delimited from each other by inner webs.
  • plastic windows are made in white. For aesthetic reasons, however, increasingly plastic windows are used, which are colored at least on their outside or provided with a decor.
  • the DE 26 05 325 A1 proposes to limit the temperature problem in colored profiles for window and door manufacturing to use in the coextruded thin cover layer of PMMA special infrared-reflective pigments. These infrared-reflective pigments are insufficiently available in the market in terms of color, light and temperature resistance. The use of infrared-reflective pigments is also out of the DE 2 247 980 A1 known for solid colored profiles.
  • a holhuntprofil is known in which the entire outer wall is made transparent to allow Absoption of the incident light to take place on the inner wall of the profile, so that a targeted heating of the profile inside is effected.
  • profiles with a colored outer wall can not be produced.
  • Object of the present invention is to provide hollow sections available that are suitable for the production of windows and doors with colored outside, without that when exposed to sunlight, an inadmissibly high heating of the profiles occurs.
  • the invention solves this problem by a hollow chamber profile made of thermoplastic material having an outer side and an inner side and at least one adjacent to the outside of the hollow chamber, said adjacent to the outside of the hollow chamber wall of the hollow chamber made of a first thermoplastic material A and at least one other wall of the hollow chamber profile is formed from a second thermoplastic material B, and wherein the first thermoplastic material A by at least 5 K higher Vicat softening temperature than the second thermoplastic material B.
  • the term Vicat softening temperature is used in this application, it means the Vicat softening temperature measured according to DIN EN ISO 306 (B50).
  • the hollow chamber profile according to the invention in contrast to the known PMMA coextrusion process in which a relatively thin PMMA layer is coextruded with a base profile made of PVC-U and in which the supporting part of the profile outer wall made of PVC-U, in the hollow chamber profile according to the invention the supporting part of the outer wall made of the higher temperature-resistant thermoplastic material A.
  • the hollow chamber profiles according to the invention are used for producing a plastic window or a plastic door, wherein the outer walls of the hollow chamber profiles are at least partially exposed to direct sunlight when installed.
  • the invention takes into account that the sun exposure exposed outer wall of the profile can warm up considerably. However, since this outer wall consists of a material - the plastic A - which has an increased heat resistance due to its higher Vicat softening temperature, the risk of distortion of the profile is considerably reduced. Since only a relatively small proportion of the cross section consists of the plastic A, this can also consist of a higher-priced material, without the total material costs are excessively increased.
  • the invention thus synergistically combines the advantages of both materials in that only the high temperature-stressed areas - the outer wall - consist of the material with increased heat resistance and the other areas of standard material.
  • the outer wall can in particular be painted, laminated with a colored film and / or also colored through or colored in some other way.
  • the outer wall is thus not transparent, but reflects a part of the incident light, while the largest part is absorbed. It is within the invention if all outer walls of the profile according to the invention are colored.
  • an additional coextruded coating in particular of colored PMMA. The underlying wall under the colored outer layer of the higher temperature-resistant material A then heats up when exposed to sunlight, but due to its increased Vicat softening temperature this is not critical.
  • the first thermoplastic material A is preferably selected from the group consisting of acrylonitrile-butadiene-styrene copolymer (ABS), acrylonitrile-styrene-acrylic ester copolymer (ASA), post-chlorinated PVC (PVC-C), SAN, HIPS, MABS, S / B / S, PC, PMMA, mixtures of these polymers with each other and mixtures of one or more of these polymers with PVC-U, with ABS, ASA and PVC-C being particularly preferred.
  • the thermoplastic material B is preferably rigid PVC (PVC-U).
  • PVC-U has a Vicat softening temperature, measured according to DIN EN ISO 306 (B50), of about 80 ° C.
  • the Vicat softening temperature measured according to DIN EN ISO 306 (B50) is from ASA and that from ABS about 100 ° C.
  • Particularly preferred for the thermoplastic material A ABS and ASA are used.
  • the thermoplastic material A preferably has a Vicat softening temperature which is at least 15 K higher, measured in accordance with DIN EN ISO 306 (B50), than the thermoplastic material B.
  • the thermoplastic material A particularly preferably has a Vicat softening temperature of 95 to 110 ° C. while the Vicat softening temperature of the thermoplastic B is between 75 and 85 ° C.
  • the hollow chamber profile according to the invention is produced by coextrusion of the first thermoplastic material A with the thermoplastic material B.
  • the hollow chamber profile with all walls and webs - with the exception of the outer wall - of the thermoplastic material B and the outer wall separately extruded from the thermoplastic material A and then both by welding, clipping o.
  • the like Hollow chamber profile are connected.
  • thermoplastic materials The coextrusion of two thermoplastic materials is known in the art, see, for. B. Walter Michaeli, Extrusion Tools for Plastics and Rubber, 2nd ed. 1991, Chapter 6.
  • the nozzle tool must be adjusted with respect to the flow channels to the specific flow properties of the melts at the extrusion temperature.
  • the advantages of the invention are particularly useful when the hollow chamber profiles are colored dark on the outside, painted or foiled. "Dark” in the sense of this invention is a color which absorbs more than 50%, preferably more than 60% of the vertically incident sunlight, including the relevant IR range.
  • FIG. 1 an inventive frame profile with two adjacent to the outside 2 hollow chambers 5, 6 is shown.
  • the two hollow chambers 5, 6 are bounded on the outside by the outer wall 4, inwardly by the walls 7 'and 7''' and by the webs 8.
  • the in Fig. 1 hatched outer wall 4 is made of ASA with a Vicat softening temperature of 100 ° C, while the other walls 7, 7 ', 7 ", 7''' and the webs 8 made of rigid PVC with a Vicat softening temperature of 80 ° C. consist.
  • the hollow chamber profile 1 was produced by the coextrusion process.
  • the outer wall 4 is colored dark brown in the mass and in addition from the outside with a dark brown wood decor foil (in Fig. 1 not shown separately) provided. All other walls are white.
  • Fig. 2 is a section through a finished window 9 with two wing frame 10 and a post 11 shown in section.
  • Reference symbol 12 symbolically denotes the sunlight, while 13 denotes the interior of the room.
  • the shaded outer walls shown are made of the thermoplastic ASA with a Vicat softening temperature of 100 ° C, while all other walls and webs made of hard PVC.
  • the dark brown colored outer wall of the profile heats up to a temperature of up to 80 ° C. This would prove in PVC-U as an impermissible temperature load, while the invention used higher heat-resistant ASA at this temperature still has sufficient strength and modulus.
