Definitions
- the invention is based on a system comprising at least one extruded or injection-molded part of a molding composition containing a polymer material, wherein the molding composition contains at least one filler for reinforcement. Furthermore, the invention relates to a method for producing such a system and the use of such a system.
- Extrusion processes are generally used to produce systems comprising at least one extruded or injection-molded part.
- extruders are used for the production of endless profiles.
- polymer material is melted and shaped under pressure by a tool into an extruded profile.
- pultrusion process it is also common to use so-called pultrusion process.
- the shaping of the extruded profile is assisted by a corresponding tool in that the extruded profile is pulled through the tool on the side facing away from the plasticizing device, for example the extruder.
- Extruded profiles of polymer materials are used, for example, as supports, cable ducts, reinforcing plates, door or window posts, door height friezes, window sills, raceways, door stops, sash windows, frames, wall and ceiling panels, furniture as well as door and window frames.
- profiles used to make doors and windows are made of polyvinylchloride.
- the profiles are generally hollow chamber profiles, each comprising at least one stiffening chamber for receiving a stiffening profile.
- a reinforcing profile for example, steel profiles or aluminum profiles or profiles made of fiber-reinforced plastic are used. From DE-A 197 36 393 it is known, for example, to insert the steel or aluminum stiffening profile or the stiffening profile made of fiber-reinforced plastic into the stiffening chamber of the plastic profile.
- steel or aluminum profiles has the disadvantage that they have a different thermal expansion coefficient than the one used Polymer material.
- Another disadvantage is that the reinforcement profiles must be inserted accurately into the plastic profile to fulfill their function.
- the extrusion of fiber-reinforced thermoplastics without a draw-off device is known, for example, from EP-B 0 820 848.
- a composite material which contains a maximum of 15% by volume of fibers is shaped into an extruded profile by a standard extruder.
- a suitable polymer a crystalline polymer of low melt viscosity is mentioned.
- the small proportion of up to 15% by volume of fibers is generally insufficient to adequately reinforce profiles such as those used in doors or windows.
- a profile strip in particular for the production of frames for windows or doors, is also known from DE-A 32 02 918.
- a core profile is made of a glass fiber reinforced polyvinyl chloride. This contains up to 50 wt .-% glass fibers.
- the core profile is connected to a sheath made of a plastic which is compatible with polyvinyl chloride and exceeds the impact resistance of the core profile.
- a lubricant additive substantially increased compared to non-reinforced PVC is required.
- the object of the present invention is to provide a system comprising at least one extruded or injection-molded part made of a polymer material which meets the mechanical strength requirements for components used for reinforcement.

- the fibers usually have a length of 0.1 to 0.4 mm.
- it preferably also contains at least one highly branched or hyperbranched polycarbonate, at least one highly branched or hyperbranched polyester or mixtures thereof.
- FIG. 4 shows a system designed according to the invention with a hollow profile in which a molded part is accommodated, in a first embodiment.
- An inventively designed system 1 comprises a hollow profile 3.
- the hollow profile is formed in the form of a rectangular profile.
- the hollow profile 3 shown here which is rectangular in shape, the hollow profile 3 but can also assume any other shape.
- the hollow profile 3 it is possible for the hollow profile 3 to assume a circular cross section, an elliptical cross section, a triangular cross section or else a cross section in the form of a polygon with any number of corners.
- the edge lengths can each be the same length or different lengths.
- the hollow profile 3 comprises in the embodiment shown here a cavity in which an extruded or injection-molded part 5 is received.
- the extruded or injection-molded part 5 is enclosed flush on all sides by the hollow profile 3. In this way, the extruded or injection-molded part 5 is fixed in the hollow section 3.
- extruded or injection-molded part 5 for fixing the extruded or injection-molded part 5 in the hollow profile 3, this may e.g. welded, glued or connected in any other, known to those skilled in the art with the hollow section 3. It is also possible, e.g. to use an extruded or injection-molded part 5 in the hollow section 3 and between the hollow section 3 and the extruded or injection-molded part 5 cavities formed with a polymeric material, preferably a polymer foam to fill.
- a hollow profile 3 with a cavity which is filled by an extruded or injection-molded part 5 it is also possible to use a hollow profile 3 with a plurality of cavities. Also, the cavities next to the square shape shown here take any other shape. Furthermore, it is e.g. also possible that e.g. Ridges protrude into the cavity. When the extruded or injection-molded part 5 rests with all sides on the walls 7 of the hollow profile 3 surrounding the cavity, the cross section of the extruded or injection-molded part 5 corresponds to the cross-section of the cavity.
- the cavity pockets are formed into which the extruded or injection-molded part 5 is inserted.
- the extruded or injection-molded part 5 is preferably enclosed at its front sides by the pockets.
- the production of the system 1 can be done for example by a co-extrusion process.
- the hollow section 3 and the extruded molding 5 are produced in one operation by the coextrusion process.
- the hollow profile 3 by an extrusion process to manufacture and insert the extruded or injection molded molding 5 from the molding compound containing at least one filler in the cavity of the hollow section 3.
- the molded part 5 is generally produced by an extrusion process or injection molding process.
- FIG. 5 shows an alternative embodiment of a system 1 designed according to the invention.
- the system 1 shown in FIG. 5 likewise comprises a rectangular hollow profile 3.
- the rectangular hollow section 3 comprises a cavity 9 into which two extruded or injection-molded parts 5 are inserted.
- the extruded or injection-molded parts 5 rest on the walls 7 of the cavity 9 with three sides.
- the attachment of the extruded or injection-molded parts takes place, for example. non-positive or positive fit.
- the extruded or injection-molded parts can e.g. welded into the cavity 9, glued, screwed or secured in any other way.
- the embodiment shown in Figure 5 is prepared by a co-extrusion process. The coextrusion process is particularly preferred if any dimensional inaccuracies that would occur would make it difficult to insert the injection-molded or extruded molded part 5.
- the hollow profile 3, as shown in Figures 4 and 5, is preferably made of polyvinyl chloride.
- the material for the extruded or injection-molded parts 5 is particularly preferably a thermoplastic polyester containing glass fibers as a filler.
- the molding compound preferably also contains highly branched or hyperbranched polycarbonates or highly branched or hyperbranched polyesters in the form of nanoparticles.
- the reinforced with the mold parts 5 hollow sections 3 can be used in any applications.
- they are suitable for the production of frames for solar collectors, panels, screens, windows or doors, for the production of wall or ceiling panels, for the stiffening of wall panels, for the production of furniture, for example shelves, chairs or tables, for the production of scaffolding, supporting frames, such as those used in mining, for the production of cladding for cable ducts or cable ducts, for the production of roof beams, for example for motor vehicles, and for the production of cross beams for roof structures.
