Definitions
- the invention relates to a press pad for use in single or multi-day heating presses, consisting of a fabric.
- Such press pads can be used in various types of high and Low pressure presses, e.g. Short cycle and stack presses for the lamination of chipboard with melamine etc., high pressure presses for the production of high pressure laminates or other presses can be used for many other areas of application.
- Typical for such press pads is that they are constructed in the form of a fabric made of materials exists or contains materials that are suitable for use at high temperatures up to above 200 ° C are suitable and both the largest possible resilience at a intermittent pressure load and have the greatest possible thermal conductivity.
- the press pads Since both the components of the aforementioned presses themselves and the material to be pressed more or have smaller tolerances, the press pads have the task of these tolerances balance and transfer the pressure evenly and over the entire surface of the material to be pressed and to ensure an even and full-surface heat transfer.
- a press cushion of the type described in the introduction is, for example, from DE 90 17 587 U1 known.
- This is a flexible press cushion fabric made from a yarn aromatic polyamide, which may be mixed with other yarn materials.
- the Textile fabric should, based on the total weight of the press cushion, metal threads in one Contain between 0 and 70 wt .-% to reduce the thermal conductivity set the required value.
- the prior art also includes the press pad known from EP 0 735 949 B1, in which the warp threads and / or the weft threads have a silicone elastomer which in the Fabrics, for example, in the form of solid threads or in the form of silicone-coated Metal wire can be included.
- Hotplate temperatures in the press systems are those to be placed on the press pads Requirements have grown steadily in the recent past.
- a disadvantage of previous press pad is i.a. to see that their chemical resistance, For example, compared to hydraulic oil, which in the event of oil leakage from the hydraulic presses Upholstery fabric can penetrate, is not sufficiently large. So is the chemical in particular Resistance of silicone elastomers or polyamides to hot oils, petrol, aliphatic and aromatic olefins and chlorinated hydrocarbons as well as acids bad or not given at all.
- the invention has for its object to propose a press pad with which the today's requirements for technically innovative applications can be met.
- Fluoroelastomers are characterized by excellent heat resistance, which is about 250 ° C and the press pad according to the invention therefore also for use shortest cycle times with correspondingly high heating plate temperatures are ideal.
- the chemical resistance of fluoroelastomers is also very good. They are for example against hot oils, petrol, aliphatic and aromatic olefins, Fluorocarbons and acids absolutely resistant.
- Fluoroelastomers due to their high elasticity even at high continuous temperatures of over 250 ° C. With the press pad according to the invention can therefore also be the hardest Operating conditions achieve much longer service lives than with the known ones Upholstery types is the case.
- the basic molecule of a (pure) silicone rubber has the following structure:
- R stands for an organo group.
- the above structural formula can be represented by the following empirical formula: - [R 2 SiO] n
- silicone rubber From such a silicone rubber, the use of press pads to the state of the Technology counts, is created by crosslinking silicone elastomer. Instead of silicone elastomer the term (silicone) rubber or (silicone) vulcanizate is also common.
- the silicone fluoroelastomer proposed according to the invention differs from the aforementioned silicone rubber or elastomer in that organo groups in the base molecule of the silicone rubber are partially replaced by tri-fluoroalkyl groups. If, for example, a tri-fluoromethyl group is present as the tri-fluoroalkyl group, the silicone fluoroelastomer has the following structural formula:
- Silicone fluoroelastomers are not only different from conventional silicone elastomers by a completely different production method, but also by considerably Different chemical and physical properties:
- Silicone fluoroelastomers are characterized by excellent heat resistance, which goes beyond 250 ° C and the press pad according to the invention therefore also for use predestined for the shortest cycle times with correspondingly high heating plate temperatures.
- the chemical resistance of silicone fluoroelastomers is very good. They are for example against hot oils, petrol, aliphatic and aromatic olefins, Fluorocarbons and acids largely resistant.
- Silicone fluoroelastomers due to their high elasticity even at high continuous temperatures of over 250 ° C.
- the silicone fluoroelastomers used according to the invention are distinguished due to their higher elasticity and better recovery properties. With the press pad according to the invention can therefore also be the hardest Operating conditions achieve much longer service lives than with the known ones Upholstery types is the case.
- Fluoroelastomer as well as a silicone fluoroelastomer to use with different proportions to each other.
- the two types of elastomer mentioned above are well compatible with each other and can complement each other in their properties.
- a substantial proportion in the sense of the invention is a content of Fluoroelastomer and / or silicone fluoroelastomer on the total weight of the press pad of at least 10%, preferably more than 20%.
- a so-called blend elastomer before a mixture of a (conventional) silicone rubber and a fluororubber and / or a silicone fluororubber is produced.
- the proportion of the fluororubber and / or the silicone fluororubber the "blend rubber” should preferably be more than 5% by weight, more preferably more than 10% by weight.
- a substantial proportion of a blend elastomer is in the sense of the invention Proportion of at least 10% by weight, preferably more than 20% by weight, based on the Total weight of the press pad to understand.
- warp and / or Weft threads have a substantial proportion of one of the aforementioned silicone elastomers. All warp and / or weft threads can be used with the respective elastomer be provided or only part of the warp and / or weft threads.
- Elastomers are molded materials that are in the range of their Use temperature that is both below and above room temperature can behave rubber-elastic. Low stresses leave a relatively large deformation to, i.e. the elastic modulus of elastomers is relatively low. Will the tension canceled, the elastomers return to their original state. The Elongation at break in the tensile test is several 100%.
- the molecules of elastomers are cross-linked.
- This degree of crosslinking is both at temperatures below 0 ° C and at very high high temperatures, i.e. up to the decomposition temperature, which is above 250 ° C can exist.
- the tensile set of elastomers is very small and lies typically around 2%.
- Elastomers are made by cross-linking (vulcanization) rubber Crosslinking agents produced. You can neither by exposure to heat nor by moderate pressure can be permanently deformed. Either serves as the starting material Natural rubber, which is a pure hydrocarbon compound, or synthetic rubbers made by polymerization, polycondensation or polyaddition getting produced. The raw material is therefore called rubber, whereas the finished one cross-linked product called vulcanizate, rubber or elastomer.
- thermoplastics are linear or more or less branched uncrosslinked polymers.
- Thermoplastics are above the Service temperature can be repeatedly formed and processed in a molten state.
- the Molecular chains are connected to each other by secondary valence forces that occur during heating or plastification and thus processing, for example in the form injection molding, extrusion, blow molding, thermoforming, etc.
- Thermoplastics not during processing due to excessive thermal stress be chemically damaged, i.e. undergo strong molecular degradation, they can current knowledge can be reprocessed several times without an essential one Loss of material properties occurs.
- thermoplastics The tensile set of thermoplastics is greater than 50% and above it Operating temperature range, they have a flow temperature range that is practical Use must be avoided if possible.
- the possible elongations at break are essential less than with elastomers.
- the elastic modulus is greater than that of elastomers, so that thermoplastics have hardly elastic properties such as elastomers exhibit.
- thermoplastic polymers with a fluorine content Polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene (ETF), perfluoroalkoxy copolymer (PFA), polytrifluoroethylene (PCTFE), ethylene chlorotrifluoroethylene (ECTFE), polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF), tetrafluoroethylene / hexafluoropropylene copolymer (FEP) known.

- EDF ethylene tetrafluoroethylene
- PFA perfluoroalkoxy copolymer
- PCTFE polytrifluoroethylene
- ECTFE ethylene chlorotrifluoroethylene
- PVDF polyvinyl fluoride
- FEP tetrafluoroethylene / hexafluoropropylene copolymer
- thermoplastic compounds differ fundamentally from those of elastomers (or rubbers).
- warp and / or weft threads have a metal content.
- This metal part can on the one hand in the form of metal powder in an elastomer material, for example in the Silicone fluoroelastomer or the blend elastomer can be introduced or in the form of Metal threads can be contained in the warp and / or weft threads.
- the weaving processing is considerably simplified if the elastomer material containing thread also a thread core with a much larger Has modulus of elasticity.
- the thread core consists of metal, in particular from a plurality of individual filaments, usually as strands be designated.
- the thread core usefully consists of copper braid or Brass braid or (precious) steel braid.
