Definitions
- the invention relates to a method for producing a Gleitbeiags from a yarn made of a chemically bonded to a polyfluorohydrocarbon yarn and a auspatitbaren resin matrix. Background of the invention
- sliding linings are used for example in pivot bearings, Axialiager, spherical plain bearings and the like.
- Gieitbelag the reduction of friction of two parts moving against each other as bearing parts.
- sliding linings have a tribologically active, friction-reducing component, for example in the form of polyfluorohydrocarbons, for example polytetrafluoroethylene (PTFE). Since such polyfluorohydrocarbons are generally less resistant mechanically, they are embedded in matrices such as resins and other hydrocarbons.
- PTFE polytetrafluoroethylene
- WO 99/61527 A1 proposes chemically bonding the perfluoroalkylsubstances to the polyamides by means of gamma rays to form functional groups such as, for example, carboxylic acid radicals grafted there way. This preparation results in comparatively amorphous powders of substrates which soften with resins be implemented a sliding coating.
- a strength of the sliding bearing is still limited by the amorphous properties of the substrate.
- the object of the invention is therefore to propose an advantageously developed method for producing a sliding coating, with which an improvement in the mechanical properties of the sliding coating can be achieved.
- the activated polyhydrocarbon is treated in a reactive extruder reacted chemically with the plastic component to form a granulate-like substrate
- the granular substrate can be finely ground. Shares of the plastic matrix can be polymerized together pol. The polymerization may occur during heating during or after spinning of the substrate.
- a plastic matrix can Pofy "amides (PA), Poiyimide (PI), copolymers such as polyamide (PA! Mixtures thereof are used for these or.
- a liquid pyrrolidine can be used as the solvent. Single or awhole fi laments can be made by a wet spinning process or by a matrix spinning process. The substrate may be spun with a carrier component into filaments such as bicomponent fibers.
- the bicomponent fiber can be heated to temperatures above a melting point of the polyfluorohydrocarbon after their preparation and thereby the carrier component is thermally decomposed.
- a yarn is produced from the filaments.
- a textile body is produced from the yarn.
- This textile body may be a wound body wound from the yarn or an endless thread of the yarn, a woven fabric, a laid nest, a fleece, a wale, a compact of the yarn or the like. From such precursors, after further textile processing, the final textile body can be produced by, for example, arranging a fabric made of the yarn into a three-dimensional shape.
- the problem is solved by chemically on a Polyamid- or Poiyamldimid matrix coupled Polyfluorkohlen asstaff as PTFE is processed into a yarn, which is then processed by means of pressing and / or winding technology to the Gieitbelag.
- the yarn can be woven into a fabric, which can be used in a row in one layer as a sliding fabric or wound in multiple layers.
- the fabric can be formed exclusively from the yarn.
- fibers of other yarn types can be processed with the yarn.
- the yarn is associated with embedding in a matrix of per se known resin, for example, epoxy resin, silicone resin, or the like as textiles.
- a matrix of per se known resin for example, epoxy resin, silicone resin, or the like as textiles.
- Wickeiisme, a solid Gieitbelag such as sliding bearing ring or a plain bearing bush. Due to the properties of this composite, it may be possible to dispense with the use of a backing layer such as a backing layer.
- the COOH groups form condensation reactions with amide groups and other functional groups and can therefore form a chemical linkage with other polymers.
- the activated and reactive PTFE can therefore chemically react with polyamides, polyamide-imides, and the like, for example, in a reactive extrusion. Reactive extrusion under shear of the activated PTFE is generally necessary to overcome steric hinderances of the carboxylic acid groups and therefore allow a chemical reaction with the plastic matrix ⁇ PA, PAI and the like). Oas activated PTFE and the plastic matrix are mixed and extruded at temperatures greater than 3 ° C.
- the degree of bonding between PTFE and the plastic matrix is adjusted by the operating conditions such that chemical coupling occurs at least at a few locations, for example, to add PTFE granules or comparable aggregates of PTFE polymers to larger dressings in the plastic material fix and secure the morphology of the resulting substrate.
- the resulting granules substrate is preferably finely ground after extrusion. In this case, a conversion into very small particle sizes can take place.
- a dispersion in solvents for example N-methyl-pyrrolidone (NMP), N-ethyl-pyrolidone (NEP) or the like and mixtures thereof.
- NMP N-methyl-pyrrolidone
- NEP N-ethyl-pyrolidone
- a polymerization such as autopolymerization of the plastic matrix can take place.
- the production of filaments for the proposed yarn from this substrate is carried out, for example, by melt spinning. Wet spinning a dispersion of the substrate and matrix spinning.
- Melt spinning refers to the production of filaments from the molten substrate. Subsequently, the melt is pressed through one or more dies and wound on a winder.
- Wet spinning means the production of filaments from solutions or dispersions of the substrate, the latter being injected into a precipitation bath with a further solvent (mixture).
- the polymer precipitates and one or more filaments can be wound up as yarn after several further processing steps.
- the wet-spinning process is used on substrates that are either non-meltable, very sensitive to temperature or that can only be processed in special solvent systems.
- matrix spinning is meant a process in which, due to a possibly high melt viscosity, the substrate is not suitable for the melt spinning process and because of its resistance to solvents it is not suitable for the wet spinning process.
- an aqueous dispersion of the substrate is mixed with a viscose gum or the like, for example in ratios of from 3: 1 to 24: 1, based on the masses of substrate and viscose, and through spinnerets pressed into an acid spinning bath ⁇ spun out). Strictly speaking, in this step no filaments of substrate but Viskosegame produced in a wet spinning process.
- the viscose serves as a matrix for the substrate ⁇ bicomponent filament ⁇ embedded in the viscose yarn.
- these viscose filaments have only a low tensile strength and not the desired chemical properties of the pure substrate. Therefore, on the one hand in a further processing step by heating these filaments to temperatures above the melting point of the substrate, for example the PTFE content.
- the substrate for example, the PTFE contained therein sintered, on the other decomposed thereby the matrix of viscose, whereby a substrate yarn - the actual yarn - is formed with a small proportion of decomposition products of viscose.
