Definitions

  • the invention is based on a wiper blade for a windshield wiper, in particular for a windshield wiper of a motor vehicle, according to the type defined in the preamble of claim 1 and a method for producing a wiper blade according to the type defined in the preamble of claim 7.
  • a wiper blade of the type mentioned in the introduction is known from practice and comprises a squeegee which is formed with a squeegee lip.
  • the squeegee or the squeegee lip consists of a rubber material that is made, for example, on the basis of natural rubber.
  • Squeegees or squeegee lips of known wiper blades have the disadvantage that when they are pressed onto a glass in a conventional windshield they have a relatively high dry friction coefficient ⁇ t r 'a and the like.
  • the wiper blade according to the invention for a windshield wiper in particular for a windshield wiper of a motor vehicle, with the features according to the preamble of claim 1, in which the wiper rubber lip is partially made of polyethylene, has the advantage that the use of polyethylene as a material for the wiper rubber lip low dry friction values ⁇ tx can be achieved ..
  • the squeegee lip can either be coated with polyethylene and / or contain polyethylene in volume.
  • the polyethylene is PE-UHMW.
  • PE-UHMW ie polyethylene with an ultra-high molecular weight, is particularly suitable for coating squeegee lips, since it already has a low dry friction coefficient as a solid material.
  • a solid material sample made of PE-UHMW with a contact length of 8 mm and a load of 0.128 N on a rotating glass shaft that moves at 0.1 m / s has a dry friction coefficient ⁇ t r of 0.21.
  • PE-UHMW bonds firmly to the rubber material by diffusion. If the PE-UHMW is applied to the rubber material as a powder, it sinters during vulcanization. PE-UHMW, in particular, adheres to a rubber material in such a way that the polyethylene-rubber composite tears in the composite from a certain load.
  • the polyethylene of the wiper blade according to the invention can be PE-HD, ie high-density polyethylene, or also PE-X, ie cross-linked polyethylene.
  • PE-X is melted onto a rubber material in the manufacture of the wiper blade according to the invention and thermally crosslinked during vulcanization.
  • the invention also relates to a method for producing a wiper blade for a windshield wiper, which comprises a squeegee with a squeegee lip. In this method, the squeegee lip is made by vulcanizing a rubber material together with polyethylene.
  • the rubber material can be made on the basis of natural rubber. However, it is also conceivable to use synthetic rubber materials as the base material for the squeegee lip.
  • the vulcanization takes place under the conditions customary for vulcanizing a rubber.
  • the polyethylene is preferably in powder form as the starting material, specifically with a grain size of approximately 0.1 to 30 ⁇ m.
  • the rubber material is coated with polyethylene before vulcanization.
  • the vulcanization of the molded part coated with polyethylene can then be carried out in a molding tool.
  • the vulcanized workpiece made of the rubber material and the polyethylene is easy to demold.
  • the coating of the rubber material with polyethylene before the vulcanization can take place in such a way that the molded rubber material is coated with a dispersion containing polyethylene particles or that the rubber material is dusted with polyethylene powder.
  • a conventional electrostatic powder coating process is particularly suitable for applying a polyethylene powder.
  • the unvulcanized rubber material is advantageously dusted over its entire surface with PE powder. However, partial coverage is possible.
  • the polyethylene can also be applied to the rubber material using a fluidized bed.
  • the rubber material is extruded hot and sticky from an extruder head.
  • the rubber material then passes through an opening into a low-concentration fluidized bed made of very fine PE-UHMW powder with a grain size between 0.1 ⁇ m and 15 ⁇ m, then leaves the fluidized bed through an opening and is then blown with clean purge air. This removes the polyethylene particles that do not adhere to the rubber material.
  • the purge air can also be used to operate the fluidized bed.
  • 'unvulcanized rubber material is pressed in a hot press with stainless steel tool, for example, at a temperature of 180 ° C and a pressure of 70 bar for a period of 10 seconds in shape, then removed and cooled with water. After drying, the partially vulcanized molded rubber part is thinly dusted on both sides with PE-UHMW powder. Then the dusted molding is at a pressure of 70 bar, a temperature of 180 ° C for a period of 5 minutes in one vulcanized to the rubber mold corresponding mold.
  • the rubber material and the polyethylene can also be connected to one another by a coextrusion process.
  • a polyethylene melt, polyethylene film, polyethylene monofilament or polyethylene cord is fed in at least in the area of the squeegee lip of the squeegee. Then the rubber material and the polyethylene attached to it are vulcanized together.
  • the wiper rubber with the wiper rubber lip by an injection molding process.
  • a film, a monofilament or a cord made of polyethylene is introduced into an injection molding prior to injection molding, or else the injection mold is coated with a dispersion or a powder made of polyethylene.
  • the squeegee lip is expediently produced from a mixture which comprises the rubber material and the polyethylene.
  • the mixture contains between 1% and 50% polyethylene powder, in particular PE-UHMW powder.
  • Figure 1 is a schematic representation of a wiper blade in cross section
  • FIG. 2 is a cross-sectional view of a second embodiment of a wiper blade
  • Figure 3 shows a third embodiment of a wiper blade in cross section
  • Figure 4 shows a fourth embodiment of a wiper blade.
  • FIG. 1 shows a wiper blade which consists of a wiper lip 2 made of rubber material, which has a wiper edge 5, a head part 3 made of rubber material, which is only partially shown here, and a so-called folding web 4 made of rubber material, which is arranged between the head part 3 and the wiper lip 2 is.
  • the wiper lip 2, the head part 3 and the folding web 4 are provided with a surface which is formed from a polyethylene layer 1 which, for the sake of clarity, is compared to the wiper lip 2, the head part 3 and the transfer bridge 4 is shown enlarged.
  • the polyethylene layer 1 consists of PE-UHMW, ie of ultra-high molecular weight polyethylene.
  • the wiper blade according to FIG. 1 is produced in such a way that first partially vulcanized rubber material is pressed in an extruder by means of a tool in the form of a wiper blade, then dusted with PE-UHMW powder and then vulcanized.
  • the vulcanization conditions correspond to the usual vulcanization conditions.
  • the material properties of the wiper rubber lip are such that, in a measurement in which the wiper blade 1 is in contact with a rotating glass plate and wiping speeds and pressure conditions are present as in a motor vehicle, dry friction values ⁇ tr between 0.32 and 0.48 can be achieved.
  • the exemplary embodiment of a wiper blade shown in FIG. 2 essentially comprises the same components as the wiper blade according to FIG. 1. However, the wiper blade according to FIG. 2 differs from that according to FIG. 1 by a so-called wiper edge 5, which is free of polyethylene.
  • the embodiment of a wiper blade shown in Figure 3 also includes essentially the same components as the embodiment of Figure 1, but differs from the latter in that the. the wiper lip 2 formed wiping edge 5, the folding bridge 4 and the head part 3 are free of polyethylene and the Wiper lip 2 is coated only in its lateral areas adjacent to the wiping edge 5, ie is only partially coated with polyethylene.
  • FIG. 4 shows a wiper blade which essentially comprises a head part 3 made of rubber material, only partially shown, a folding web 4 made of rubber material adjoining the head part 3 and a wiper lip 6 with a wiper edge 5.
  • the wiper lip 6 consists of rubber material, in which polyethylene in the form of PE-UHMW is embedded.
  • the wiper lip 6 is made from a starting material that contains about 40% polyethylene.
  • the squeegee is an extrusion.
  • the squeegee can also be produced in a known manner by an extrusion process or by compression molding.
