Definitions

  • the invention relates to a fuel tank accessory, a fuel tank, in particular, a motor vehicle fuel tank, and to a method for producing a fuel tank accessory.
  • EP 1 108 653 A2 discloses a fuel tank with a container region composed of HDPE and an accessory composed of an immiscible blend of fuel-resistant plastic such as polyamide, HDPE, and a compatibilizer.
  • U.S. 2003/0124281 A1 also discloses an accessory. It has an injection-molded connection nipple made of a glass-filled polyamide that is attached to a coextruded film composed of a polyamide, a functionalized polyethylene, and a polyethylene of higher density. The element thus created is welded onto a single-layer or multilayer tank composed primarily of HDPE. This approach allows only a fluid- or vapor-conducting system with a joining zone composed of a coextruded multilayer laminate to be produced.
  • DE 195 35 413 C1 discloses a component that is composed of a tubular thermoplastic body that features a stepped annular body on one end and a retaining ridge on the opposite end. Opposite the inner diameter of the body, a circular ring with a projection is molded on, offset by the wall thickness of the body. In the stepped annular body, an intermediate layer is incorporated as an adhesion promoter. Below that, enclosing the ring with the projection, an annular body element is molded on. The annular body element, the intermediate layer, and the circular ring of the tubular body, in addition to the mechanical connection that is effected by the circular projection, are joined together by means of heat.
  • the plastic of the annular body element is cross-linked such that a chemical bond is created between the plastics of both parts by means of bridging the interface between the parts.
  • the tubular body is divided into an inner tubular body and an outer tubular body.
  • WO 2008/113821 A1 which the invention uses as a starting point as the closest prior art, discloses a fuel tank accessory that features a first region that is composed of a first plastic, and a second region, whereby the second region features a mixture of the first plastic and a second plastic, whereby the first and second regions are integrally bonded to one another. Due to the second region being composed of the mixture, an integral connection of the fuel tank accessory with an outer wall of the fuel tank is made possible, whereby the outer wall is composed of the second plastic.
  • the disadvantage here in particular is the technical time and effort required to produce such a fuel tank accessory, as this features two different regions composed of different plastics or plastics mixtures, which must be integrally bonded to one another before integral bonding with the fuel tank is possible.
  • the object of the invention is to create an improved fuel tank accessory and the method for its production, as well as a fuel tank system.
  • Embodiments of the invention have the particular advantage that the fuel tank accessory is cost-effective to produce and can be attached to a fuel tank in an operationally reliable manner.
  • fuel tank accessory here is understood to mean all components that are suitable for installation on a fuel tank, in particular spouts, valves, in particular tank venting valves, closing elements, or similar.
  • the first plastic is a fuel-resistant plastic.
  • fuel-resistant plastic refers to a plastic that does not swell, or swells only slightly, and that manifests little to no permeability to fuel or oil when it is exposed to fuel or oil over an extended period of time.
  • fuel-resistant plastic here means one that complies with the Lev II and PZEV standards with regard to emissions.
  • the first, fuel-resistant plastic can be, for example, polyamide (PA), in particular PA 12, or polyoxymethylene (POM).
  • PA polyamide
  • POM polyoxymethylene
  • the first plastic can also be another fuel-resistant thermoplastic or a fuel-resistant mixture of compatible plastics.
  • the second plastic is a non-fuel-resistant plastic.
  • non-fuel-resistant plastic is a plastic that swells or otherwise changes significantly in its dimensions or mechanical characteristics if it comes into contact with fuel for an extended period of time, and/or a plastic that is permeable to fuel or oil.
  • a second, non-fuel-resistant plastic can be polyethylene (PE) or polypropylene (PP).
  • the second plastic can also be another non-fuel-resistant thermoplastic or a mixture of compatible plastics that are not fuel-resistant.
  • the first and second plastics are inherently not miscible.
  • the mixture therefore contains a compatibilizer to make the first and second plastics miscible.
  • Embodiments of the invention are particularly advantageous in that they reduce the costs of a fuel tank accessory.
  • the first fuel-resistant plastic is significantly more expensive than the second, non-fuel-resistant plastic.
  • the first and second plastics are not miscible with one another and therefore normally no integral, impermeable bond can be produced between the two plastics, according to the prior art in general, such a fuel tank accessory consists mainly or entirely of the first plastic, which is correspondingly expensive.
  • those regions of the fuel tank accessory that are exposed to fuel during normal operation, that is, after the accessory is installed on a fuel tank and the fuel tank is filled with fuel, are produced from the first plastic; whereas one or more other regions that normally are not exposed to fuel, or not directly exposed, are produced from the mixture that features only a certain proportion of the first plastic, in order to enable the integral bonding with the first parts.
  • the present invention departs from this basic approach in that not merely a single region that is required for the integral bond with the fuel tank is produced from the mixture of the first and second plastics, but preferably the entire fuel tank accessory is produced from the mixture of the first and second plastics, such as through a 1-component injection molding process, an extrusion process or another molding process.
  • the fuel tank accessory can be produced through a 1-component plastic injection molding process, in which the plasticized mixture, consisting of the first and second plastics and the compatibilizer, is injected into a mold.
  • the fuel tank accessory nevertheless surprisingly achieves sufficient fuel-resistance, due to the first plastic present in the mixture. This makes it possible, on the one hand, for the invention to reduce the production-oriented expense of manufacturing the fuel tank accessory, as the quantity of material of the first plastic is economized due to being partially replaced by the second plastic, and on the other hand for the invention to, surprisingly, still achieve sufficient fuel resistance, even in long-term operation.
  • embodiments of the invention also have mechanical advantages:
  • the compatibilizer is a copolymer of the first and second plastics.
  • the use of such a compatibilizer has the particular advantage that there is no need for a further raw material beyond the first and second plastics to be brought into the mix.
  • Such a third material could namely be problematic in terms of its permeability and long-term durability.
  • the polymer is a “graft copolymer.”
  • graft copolymer means a copolymer that is produced as follows: to manufacture the graft copolymer, one of the first and second plastics is grafted such that the grafted plastic can then form covalent bonds with the other of the two plastics.
  • the grafting of the plastic is effected, for example, with a reactive moiety such as a maleic anhydride or an acetic acid moiety.
  • the copolymer then works similarly to an emulsifier in the mixture of the first and second plastics.
  • the copolymer is produced with the aid of an additional compatibilizer, which is added to a mixture of the first and second plastics in solid or liquid form, and which is at least partially consumed during the copolymerization.
  • the additional compatibilizer thereby reacts with the first as well as the second plastic.
  • the additional compatibilizer contains reactive isocyanate groups and/or oligomers with epoxy groups and/or (maleic acid) anhydride groups or oxazoline groups.
  • the proportion of the first plastic in the mixture is less than the proportion of the second plastic.
  • the portion of the first plastic can be a maximum of 35 wt. %, in particular between 20 and 30 wt. %.
  • the fuel tank accessory is designed at least in one first region for an integral bond with a second area, whereby the second region is located on an outer wall of the fuel tank.
  • the second region consists of the second plastic so that due to the presence of the second plastic in the mixture, the integral bond can be realized.
  • first and second regions are directly connected to one another.
  • the first region is enhanced such that it is fuel-resistant and simultaneously attachable. This attachment is an integral bond.
  • non-fuel-resistant plastic substantially reduces the cost of producing the fuel tank accessory. The higher the portion of non-fuel-resistant plastic is, the more cost-effective becomes the mixture used and therefore also the fuel tank accessory.
  • the mixture can contain at least
  • Approx. here means, for example, a range of +/ ⁇ 5% of the respective value given.
  • the first plastic can be a polyamide and the second plastic a polyethylene.
  • PA6, PA66, PA11, PA12, PA6-T i.e., the entire polyamide palette
  • the entire polyethylene palette can be used.
  • the compatibilizer can be a copolymer of the first and second plastics.
  • the copolymer can be a reactively produced copolymer.
  • the copolymer can also feature an additional compatibilizer.
  • the additives can be stamped metal filters, flame retardants, impact resistance modifiers, static inhibitors, conductivity additives, and similar.
  • the filler materials can be glass fibers, glass beads, mineral compounds, or similar.
  • the copolymer annular element can be located on the tubular body element at a distance from the tube outlet of the tubular body element. This will keep the fuel away from the welded joint.
  • An inner diameter of the tubular body element can be larger than a diameter of the opening of the container.
  • the tubular body element can feature at least one circular connecting rib.
  • the fuel tank accessory can perform a function as, for example, a spout, tank venting valve, closing element or similar.
  • a layer can be applied at least partially to at least one surface element of the copolymer-flange body, that is, to the second component.
  • This layer further strengthens the positive adhesive qualities.
  • the layer can therefore be applied to the complete surface element or only at certain points. Even a selectively applied layer ensures good adhesive qualities.
  • This layer can be approx. 0.001 ⁇ m to 100 ⁇ m thick.
  • the layer can be implemented, for example, by plasma coating, such as that known, for example, from DE 102 23 865 A1.
  • the plasma coating can be effected on a joining surface of the copolymer-flange body with a chemically active layer, whereby the layer can contain, for example, low-molecular-weight polymer fragments.
  • the copolymer-flange body can consist of approx. 10 to 85 wt. % of polyamide and approx. 85 to 10 wt. % of polyethylene as well as approx. 5 wt. % additives.
  • an identical proportion of polyamide to polyethylene is possible. How the proportions are divided up depends on the particular conditions of application. But it is also possible that the flange body can consist of layers having different mixture ratios.
  • a polyethylene flange body can consist of approx. 95 wt. % polyethylene and approx. 5 wt. % additives. These common additives can be stabilizers, lubricants, dyes, metal filters, metallic pigments, stamped metal filters, flame retardants, impact-resistance modifiers, static inhibitors, conductivity additives, and the like.
  • the inner diameter of the flange body can be greater than a diameter of the opening of the tank. This allows the connection area to be at least partially removed from the area of influence of the fuel and its vapors and thus counteract the swelling forces.
  • a first tubular body element can terminate in a connection unit at the end facing away from the tank.
  • the component can be used as a spout.
  • a second tubular body element can be closed with a cover element at the end facing away from the tank.
  • a cover element can be used as a closure element for non-required openings of the tank.
  • At least one connecting tubular element can be located below the cover element of the second tubular body element. This provides a housing for a tank venting valve into which a valve element can be inserted.
  • connection unit and/or the connecting tubular element can terminate in at least one circular connecting rib. This allows a hose to be connected.
  • the invention in another aspect, relates to a fuel tank, in particular a motor vehicle fuel tank such as a fuel tank for a passenger car.
  • the fuel tank has an opening and an outer wall that can consist of the second plastics material.
  • the fuel tank accessory is guided, for example, partially through the opening in the fuel tank and in its first region is integrally bonded with the outer wall of the fuel tank, for example, in that a joining surface of the first region is welded to the outer wall.
  • the welding of one or more fuel tank accessories according to the invention results in a fuel tank system.
  • the invention in another aspect relates to a method for producing a fuel tank accessory.
  • a joining surface of the first region is pretreated in order to increase the reactivity of the joining surface.
  • This can take place through a plasma treatment of the joining surface, for example with the aid of a plasma tip, such as that known from EP 0 986 939 B1.
  • the plasma treatment causes not only an increase in reactivity but also an improvement in compatibility, specifically by removing passivating layers that can adhere to the joining surface.
  • pre-treatment of the joining surface can be effected through plasma coating, flame treatment, chemical etching or a mechanical pre-treatment. The increased reactivity due to such a pre-treatment of the joining surface is particularly advantageous for the realization of the integral bond between the first and second components.
  • the integral bond is generated through two-component or multi-component plastic injection molding.
  • the second component is initially created by injecting the mixture into a mold.
  • the mold is then opened in order to pre-treat a joining surface of the second component, for example, with a plasma treatment or a plasma coating.
  • the first component is produced and integrally bonded to the second component by injecting the first plastic into the mold.
  • Embodiments of the invention are particularly advantageous because the formation and joining together of the first and second components, that is, for example a tubular body element and a flange body, can be effected in a particularly cost-effective manner.
  • At least one surface element, specifically a joining surface, of the flange body can be coated with a plasma, after which the flange body with the plasma-treated surface element is connected in a fluid-tight manner with the annular body element.
  • the coating saves material while simultaneously increasing adhesion.
  • the layer can be created in two different ways:
  • a gas in a gas atmosphere can trigger a discharge, which extracts ions from the flange body, atomizes them and accelerates them a short distance; said ions can be focused as a jet onto the surface element.
  • the discharge can be triggered as gas from air or components of the air, or from a noble gas or a noble gas and its compositions.
  • the noble gas can be helium, neon, argon, krypton, xenon, radon and mixtures and/or compositions thereof.
  • gas can contain components that react in an open state with the surface element of the flange body and can form a second layer.
  • components of an organic type can react in air as gas.
  • components of an inorganic type can also react in air as gas.
  • a surface element of a flange body or the surface elements of a number of flange bodies can be treated. Because the treatment can take place in the open, that is, not in a vacuum, the costs are reduced on a lasting basis.
  • a body can first be formed from a thermoplastic material that can be at least partially coated with a polyamide body.
  • the high-cost material is applied to a cost-effective material in order to use predominantly its positive qualities.
  • thermoplastic material body can be formed from polyester, polyacetate, polyolefin, fluorothermoplastic, polyphenylene sulfide, or a less expensive polyamide that is less resistant to fuel.
  • the flange body can be welded with the tank. Whether spouts or a blank flange or a tank venting valve, all of these components can be tightly welded to the container in the same manner, over the openings at different places. This reduces costs for the final assembly.
