Definitions
- the invention relates to an adhesive fastener part, in particular for foaming upholstery parts of vehicle seats during their manufacture, with adhesive elements on one side for connecting to corresponding adhesive elements of another adhesive fastener part to form an adhesive fastener and with a connecting means on the other side of the adhesive fastener part for establishing a connection with the respective foam material.
- Such adhesive fastener parts are known from EP 0 61 2 485, the adhesive fastener part being inserted into a foaming mold in such a way that the connecting means in the form of loop elements on the back of the adhesive fastener part come into contact with the respective foam material to produce a firm connection therewith.
- the opposite front of the fastener part has the adhesive elements in the form of connecting hooks, adhesive heads or the like. on, which are protected against the ingress of foam material, for example by this, as described in the European Script, from an uncrosslinked thermoplastic are completely surrounded.
- the adhesive elements are exposed and can later be connected to adhesive elements of another adhesive fastener part, for example in the form of a loop band, to form a conventional adhesive fastener.
- upholstery cover materials can be attached to foamed upholstery parts of a motor vehicle seat or passenger seat, or rotating components, for example in the form of grinding wheels, can be connected to tool holders on conventional grinding machines and devices.
- the foam material mentioned can be extremely thin and have viscosities that are in the range of water or below. It has now been shown that when using loop and loop material as a connecting means or when using adhesive fleece or the like. the loops, which are open per se, are not completely penetrated by the foam material, but rather form a kind of barrier for this, which prevents the penetration of the foam material.
- void points then occur at the transition points between the loop material and the foam, that is to say gaseous hollow inclusions which counteract a firm connection between the adhesive closure part and the foam material. Due to the reduced strength of the connection between the adhesive fastener part and the foam material in this way, the connection is loosened, in particular under long-term stresses, and the adhesive fastener part tears out of the foam material, which overall can render the entire component unusable, for example in the form of a vehicle seat or a grinding wheel holder.
- the invention has for its object to further improve an adhesive fastener part of the type mentioned in such a way that a secure and high-strength connection between the adhesive fastener part and the foam material used in each case can be achieved.
- a corresponding object is achieved by an adhesive closure part with the features of claim 1.
- the connecting means consists of an adhesive primer applied to the other side of the fastener part, a kind of primer layer is formed on the fastener part, which forms a high-strength connection with the respective foam material and thus a secure, difficult to solve connection between the fastener part and the later foam body guaranteed.
- the adhesive fastener part in question is formed from a polyamide material, resorcinol, polyurethane and post-crosslinkable polymers are used as the adhesive base. If the fastener or the arrest is formed from polyolefin, are preferably used as an adhesive or primer polyurethane or polymers that are re-crosslinkable.
- the adhesive closure part can be releasably inserted into the metallic foam mold and is positioned within the mold by magnetic forces in the inserted position. In this way, the insertion of the tape-like fastener part in foam molds can be achieved particularly cost-effectively.
- the adhesive fastener part is explained in more detail below with the aid of various exemplary embodiments and associated manufacturing processes. In principle, they show the
- the presented fastener part is used in particular for foaming upholstery parts of vehicle seats (not shown) during their manufacture.
- the band-like adhesive fastener part which, however, can also form flat geometries, has adhesive elements 10 on one side for connection to corresponding adhesive elements of another adhesive fastener part (not shown) to form a conventional adhesive fastener.
- the adhesive fastener part shown in FIGS. 1 to 3 is produced using a conventional method, as is shown for example by DE 1 96 46 318.1.
- a connecting means 12 is provided for establishing a connection with the respective foam material.
- the connecting means 12 consists of an applied primer, ie a so-called primer layer.
- Adhesive primer is the name for adhesion-promoting media for painting or coating. They are extremely thin and therefore sprayable and brushable. This results in very thin layers (0.005 to 0.008 mm). Their adhesion-promoting effect is based on the chemical reaction of their components with one another and with the respective surfaces, for example made of metal or plastic, which is why the term "reaction primer” is also used. Adhesive primers usually result in a glazing layer. Primers are generally used to denote primer coatings with an adhesion-promoting effect. They are sometimes referred to as reaction primers and are assigned to the primers.
- the adhesive fastener part itself is made of a polyamide or a polyolefin material.
- Polyamide is the collective name for high-molecular compounds that consist of building blocks (amides) linked by peptide bonds.
- Conventional polyamides such as PA6 or PA66 can be used as the polyamide material.
- nylon is also used synonymously with polyamide as a generic name (original trademark of Du Pont for PA66).
- R mostly hydrogen and R 2 hydrogen, a straight-chain or branched saturated aliphatic or a cycloaliphatic group.
- Polyolefins with great technical importance in the field of fasteners are, for example, polyethylenes, polypropylenes, polybutenes, which are sometimes also misleadingly called polybutylenes or polybutenes, and polyisobutenes and poly (4-methyl-1-pentene) e.
- Polymers of the higher a-olefins e.g. However, polyd-hexene), poly (l -octene) or polyd -octadecene) have found only very limited technical application in this field.
- the polyolefins also include copolymers of different olefins, e.g. that of ethylene with propylene.
- Fig.1 relates to an adhesive fastener part made of polyamide material.
- the adhesive primer used here as a primer layer later forms a firm bond with the foam during its production by means of pressure and / or heat via hydrogen bonding and with the involvement of Van der Waals forces. Adhesive forces also act. This refers to the adhesive effect between a solid interface and a second phase, which can either consist of individual particles, molecules, droplets or powders or of a continuous liquid or solid film. Adhesion can be controlled by electrostatic forces, by van-cle '-' ⁇ aals forces (these belong to the intermolecular forces) or even be caused by real chemical bonding (e.g. in the case of chemisorption).
- the primer consists of resorcinol and / or one of its derivatives, which can be applied, for example, from alcoholic solutions.
- Resorcinol or (1, 3-dihydroxybenzene, 1, 3-benzenediol) forms large, colorless, sweet-tasting needles and has a melting point between 109-1 1 1 ° and a boiling point of 280 °.
- Resorcinol is slightly soluble in water, alcohol, for example in the form of ethanol, ether and glycerol, in chloroform and carbon disulphide. In the present case, it serves as an adhesion promoter for the polyamide material.
- An applicator roller 14 which removes the resorcinol from a bath 1 6 onto the underside of the band-shaped adhesive closure part, serves as the application device for the resorcinol.
- 70 g of resorcinol are used in 930 g of ethanol, the adhesive fastener tape being guided along the roller 14 at 12 m per minute.
- a drying channel 1 8 there are approx. 70 ° C for the drying process.
- polyurethane or a polyurethane composition is used as the adhesive base, the adhesive fastener again being formed from a polyamide material.
- Polyurethanes are the general term for polymers (polyadducts) with groupings of the type which are accessible by polyaddition from dihydric and higher alcohols and isocyanates
- polyurethanes are manufactured as prepolymers with terminal isocyanate groups that are used when exposed to moisture from the environment Harden chain extension and crosslink if necessary. Such prepolymers can also be chain-extended with diamines, giving rise to polyurethanes which contain urea groups. NCO-terminated prepolymers play an important role in the production of polyurethane dispersions.
- polyurethane can have very different mechanical properties, which can also be found as more or less hard elastomers in fiber form or as polyether or polyester urethane rubber as thermosetting casting resins (also glass fiber reinforced) and especially as foam plastics can be used.
- the polyurethane material is applied to the underside of the adhesive fastener part with the adhesive elements 10 via an application nozzle 20.
- a polyurethane coating process therefore takes place, the drying process now again taking place in the drying duct 18 at 100 ° C. and the transport speed being 6 meters per minute.
- ferromagnetics is the name for such magnetic materials that show ferromagnetism, the magnetization occurring under the influence of an external magnetic field.
- a substance is ferromagnetic only at temperatures below the Curie temperature, with elements such as iron, cobalt, nickel and alloys of these components (Heusler alloys) usually being added to the ferromagnetics today.
- the embodiment according to FIG. 3 relates to an adhesive primer made of polymers which are produced by post-crosslinking, for example by irradiation by means of UV lamp 22, of curable resins, such as epoxy compounds. Hardening via ionizing rays is also called lacquer hardening designated. Epoxy resins in particular can be used well as curable resins. In the case of lacquer hardening, adhesive primers or primers applied in the liquid state are hardened to form stable surface layers. Polymerizable coating systems can be cured with ultraviolet radiation or other ionizing radiation. For UV crosslinking via UV lamps 22, mercury vapor lamps are usually used as light sources, which are also suitable, inter alia, for acrylic and certain polyester paints. Varnish curing using electron beams (ESH, EBC) can polymerize varnishes containing monomers into hard, resistant films. The polymerization takes place in fractions of a second.
- ESH electron beams
- the epoxy resin composition used is 873 g of the material sold under the brand name Uvacure 1 534, 97 g of tripropylene glycol and 30 g of FX-51 2.
- the application is carried out via a doctor device 24 and the belt speed is 8 m / min for the fastener part.
- the ultraviolet lamp 22 generates 1 20 watts per cm.
- the respective fastener part is made of a polyolefin active ingredient, it can be coated in accordance with the method according to FIGS. 2 and 3. In this respect, the statements made above also apply to a polyolefin closure.
