Definitions

  • the invention relates to a method for the production and recycling of operating resources, which are used, for example, when painting or coating vehicle parts to hold, cover, transport or fasten them or for assembly.
  • a defined paint application is to be ensured by a predetermined position of the part with respect to a paint application device.
  • paint denotes all customary coloring and coating agents which are applied by means of spraying, dipping, brushing, knife coating or the like coating techniques. be worn.
  • the term “painting” is accordingly to be understood generally.
  • An essential point of the invention is that, unlike in the conventional way, metal for the production of the operating resources is used, but that materials are used that are recyclable in an ecologically and economically simple manner in the lacquered state and can be recycled without time-consuming pre-treatment or post-treatment.
  • the equipment according to the invention is first produced using the injection molding process and ground in a coated state after each use, the resulting powder being able to be used again directly for the production of the equipment, starting a new cycle.
  • a certain amount of original raw material is added to the injection molding process in the recycling operation. This can be particularly advantageous if the quality of the recycling product contaminated with lacquer is no longer satisfactory.
  • the functionality of the equipment can be maintained with the advantages mentioned.
  • the amount of original raw material added has been in the range from 3% by weight to
  • 30% by weight preferably in the range from 5% by weight to 20% by weight and particularly preferably in the range from 8% by weight to 15% by weight, has proven successful.
  • a slight addition in the range of about 10% by weight of the original raw material is sufficient, which guarantees repeated use of the recycling product without sacrificing the mechanical and heat-stable properties, in particular also for injection molding.
  • a temperature-resistant plastic with a continuous use temperature in the range from-150 ° C. to 280 ° C., preferably above 170 ° C. is used as the original raw material.
  • Plastics with such a long-term use temperature have good properties for injection molding production processes, since on the one hand thermoplastic deformability and on the other hand mechanical stability in the cooling state is guaranteed. This delays the aging process of the plastics.
  • the original raw material is selected as one or more of the following substances: polysulfone, poly (aryl ether) ketone, poly (ether sulfone), ABS (acrylonitrile / butadiene / styrene), polyamides or similar thermoplastics (see also plastics compendium, bird Specialist book, 4th edition 1996 by Dr. A. Franck, ISBN 3-8023-1589-8).
  • plastics are suitable for the method according to the invention, which with fibers, such as. B. glass or carbon fibers or reinforced with Kevlar, or the like reinforcing materials.
  • a fiber-reinforced plastic is therefore preferably used as the original raw material.
  • Glass fiber-reinforced polyamide has proven to be the best plastic in terms of procurement costs, recyclability, injection moldability (optimal flow behavior) and mechanical properties, especially at high temperatures, such as those found in stoving ovens for paints.
  • the operating material or the original raw material is reinforced with a filler with a filler weight fraction of 0.1% by weight to 40% by weight.
  • a filler weight fraction 0.1% by weight to 40% by weight.
  • a further advantage of the method or of a method product according to the invention is that a lacquer adhesion to the glass fiber reinforced polyamide is more impact-resistant and stable in comparison to metal, and thus the flaking off
  • Lacquer is less, which reduces the risk of contamination of a freshly coated surface.
  • This property of the optimized coating adhesion to plastics such as fiber-reinforced plastics in general and glass fiber reinforced polyamide, in particular, has proved particularly advantageous manner with the use of the process product as a vehicle part, in particular as a vehicle body and / or to ⁇ cessories in part because they are often high are exposed to mechanical stress.
  • the method is also suitable for the manufacture or mounting of furniture, products in road traffic, for example also for signs, manhole covers and other commodities; also in the household.
  • the process product is also particularly suitable, for example, for front flaps, tailgates, fenders or side walls.
  • the plastic parts manufactured and painted according to the invention can be practically 100% recycled for a further injection molding process.
  • the use of the process product as a production aid for example as a masking agent during a painting process or as a holding, fastening or transport means, is proposed.
  • the method according to the invention thus represents an ecological concept which makes mechanical, thermal or chemical stripping unnecessary, because the equipment according to the invention can be fed to the injection molding again after being ground or pulverized. This process can be repeated almost any number of times, with small amounts of original raw material being added if necessary in order to maintain optimized properties of the injection molding material.
  • the use of the equipment according to the invention is superior, even from an economic point of view, to the mostly expensive equipment made of metal that has been used up to now.
  • the user for example the household appliance or vehicle manufacturer
  • the user is not burdened with the provision and disposal of the operating resources, since this task is performed by suppliers who have injection molding technology.
  • the core activity of these companies is the grinding of bulk goods and the use of the recycled product for the production of operating resources. Since such equipment is used in many branches of industry, a rational and cost-effective production Position of the equipment guaranteed by these suppliers.

Abstract

La présente invention concerne un procédé destiné à la réalisation et au recyclage de moyens techniques qui sont utilisés pour le laquage ou le revêtement de pièces de véhicules pour permettre leur maintien, recouvrement, transport ou fixation, ou pour le montage du véhicule. Les moyens sont produit par un processus de moulage par injection, broyés après utilisation à l'état laqués, puis à nouveau utilisés en tant que matière première sous la forme de poudre dans le processus de moulage par injection pour produire des moyens techniques.
