Definitions
- the invention relates to a press pad made of an asbestos-free material for high-pressure single-day presses or for high-pressure short-cycle presses, in each case for the production of high-pressure laminates, the press pad having a textile fabric which contains yarn made from an aromatic polyamide and metal threads.
- both decorative and technical high-pressure laminates are produced. While the pressure in high-pressure single-day presses is between approx. 850 and 1200 N / cm 2 and the pressing time is between approx. 20 and 120 minutes, the pressure in high-pressure short-cycle presses is between approx. 800 and 1000 N / cm 2 and Pressing time only about 1 to 2 minutes.
- the temperature ranges are similar and are approx. 130 ° to 160 ° for the single-day presses and approx. 130 ° to 180 ° for the short-cycle presses.
- a difference between the above types of presses is that the press pad in the one-day presses is normally moved in and out of the press together with the material to be pressed, whereas the press pad in the high-pressure short-cycle presses remains in the press itself and there between a heating plate and a press plate is arranged.
- the press pads each have the task of transferring the press pressure evenly and over the entire surface to the laminate to be produced. This essentially results in matching requirements for the press pads, namely good thermal conductivity for transferring the heat from the heating plates to the material to be pressed and good elasticity in order to return to the initial state as far as possible after the pressing pressure has been released at the end of a cycle. This is the only way to create sufficient deformability for the next pressing process.
- An essential factor for the quality of a press cushion is the ability to maintain its resetting properties even at high pressures and temperatures over long periods, ie a large number of press cycles.
- a press pad of the type described above is known for example from German utility model 90 17 587. Depending on the thermal conductivity required, this asbestos-free press pad can have a different high proportion of metal threads.
- the metal yarns can be worked into the fabric in different ways on the one hand as metal threads that wrap around the textile yarn or on the other hand as pure metal yarn or also in the form of any combination of the aforementioned options.
- warp and weft are preferred as the type of weave of the fabric, the two thread systems being able to consist of any combination of textile yarn or a textile yarn mixture, monofilament or multifilament metal yarn, textile yarn or textile yarn mixture wound with metal yarn or in turn any combination of the three types mentioned above , Due to the almost freely adjustable thermal conductivity due to the proportion of metal threads, both single-layer and multi-layer fabrics with good product properties can be achieved.
- German utility model 92 03 498 proposes that the top and / or needling a fleece onto the underside of the fabric layer of the press cushion.
- the surface, which is rough or rough due to the fabric structure of the press cushion, is smoothed by the applied fleece, so that the outer surfaces of the press cushion are completely smooth.
- the needling of the fleece onto the fabric layer takes place in such a way that the fleece is mechanically hooked to the fabric layer of the cushion using specially shaped needles or barbs.
- a disadvantage of this known press pad is that it occurs as a result of the constantly changing pressure load on the pad and as a result of temperature fluctuations, relative movements of the pad surface to the adjacent press plates or heating plates. This leads to abrasion in the form of fiber pieces of the fleece on the contact surfaces formed by the needled fleece. This abrasion inevitably gets from the space between the press plate and the heating plate into the room in which the high-pressure press is installed. In particular in the manufacture of technical high-pressure laminates, such as the printed circuit boards for the electronics industry, such contamination of the ambient air by fiber particles is intolerable, since this affects the product quality of the printed circuit boards produced.
- a press pad is also known from EP 0488 071 A2, which is also used for high pressure applications in the range between 400 and 1200 N / cm 2 and at temperatures of 160 ° to 220 ° C is suitable.
- This press pad is a multi-layer fabric with preferably 3 to 6 layers, consisting of warp and weft threads made of a heat-resistant plastic filament.
- the fabric as a whole is impregnated in a liquid bath made of a synthetic resin and a suitable solvent, the proportion by weight of the impregnating resin in the total weight of the finished cushion being in the range between 1% and 10%.
- DE-OS 23 19593 discloses a press pad for low-pressure presses in which the press pressure is approximately in the range of 350 N / cm 2 .
- This known press pad consists of a metal screen fabric, preferably of bronze threads, in which the spaces are completely filled with a silicone elastomer. This gives very good elasticity and resilience properties, which are due to the special material properties of the silicone material. Press pads of this type are also suitable for changing the format of the material to be pressed, without the dreaded “window frame effect” that is typical of conventional press pads for low-pressure presses.
- thermal conductivity properties of this cushion can be adjusted using metallic additives in the silicone elastomer. For high pressure applications, this is comparatively expensive and also specifically very heavy upholstery.
- the invention is based on the object of proposing a press cushion for use in high-pressure presses which are suitable for operation under clean room conditions and which is distinguished by a large resilience and good resilience properties.
- this object is achieved according to the invention in that the tissue is superficial at least on one side is provided with a coating of a heat-resistant and pressure-resistant polymer material, which covers the entire surface of the fabric in the form of a continuous layer.
- the formation of fiber abrasion from the press pad is significantly reduced, especially if the side of the press pad provided with the coating in the form of a continuous layer faces the press plate, which due to its comparatively rough surface tends to produce a much greater abrasion than the heating plate, which is smoother in comparison. Since the coating of the press pad according to the invention is only applied superficially, the fabric structure underneath with the air inclusions is fully preserved, so that the suspension properties of such a pad are very good.
- the continuous coating applied superficially according to the invention differs from the resin impregnation known from EP 0488 071 A2, which extends as a result of an impregnation on the entire fabric surface, that is to say the surface of all the threads.
- the coating according to the invention also differs significantly in its effect from the filling of the interstices of the bronze fabric known from DE-OS 23 19 593 by means of a silicone elastomer, since in the case of this known press pad no air pockets are present within the finished press pad.
- the press pad according to the invention is preferably provided on both sides with a continuous polymer coating, as a result of which the air pockets in the textile fabric located therebetween support the cushioning effect in the manner of a gas spring due to the gas tightness of the two continuous layers.
- the polymer material be a polytetrafluoro compound, such as. B. PFA, FEP, ETFE, PCTFE, PVDF or ECTFE.
- a polyetherimide can also be used as the polymer material.
- the polymer material is an elastomer material, a silicone elastomer or a fluoroelastomer or a silicone-fluoro elastomer appearing to be particularly suitable.
- the latter two materials are characterized by their excellent resistance to oils or other chemicals with a very good cushioning effect.
- the elastomer material is made from a mixture of a silicone rubber and a silicone-fluorine rubber. With the aid of such blend elastomers, the costs can be reduced, for example compared to pure silicone-fluoroelastomers, without having to accept a significant loss in material properties in comparison to a pure silicone-fluoroelastomer.
- the textile fabric should preferably contain solid metal threads which are easy to incorporate in terms of weaving technology.
- the proportion of metal threads in the total weight of the press cushion should be between 1% and 70%, preferably between 10% and 70%.
- the coating contains thermally conductive fillers, so that in cases where a high thermal conductivity of the press cushion is required, this can also be achieved without a very high proportion of metal thread in the textile fabric.
- the invention is explained in more detail below using an exemplary embodiment of a press pad, which is shown in the drawing.
- the drawing figure shows a cross section through a press pad coated on both sides with a silicone-fluorine elastomer.
- a press pad 1 for use in a high-pressure press has a textile fabric 2, which consists of warp threads 3 and weft threads 4, each of which is a multifilament yarn made from an aromatic polyamide.
- the warp threads 3 are wrapped by a brass thread 5.
- the thermal conductivity of the fabric 2 can be adjusted with the aid of the frequency of wrapping and the thickness of the metal threads 5.
- the fabric 2 is provided on both sides with a coating 6 and 7 made of heat-resistant and pressure-resistant silicone-fluorine elastomer.
- the coatings 6 and 7 completely cover the fabric 2 in the form of a closed layer. Air pockets 8 remain within the multifilament yarns that form the warp threads 3 and the weft threads 4, as well as in gap areas between the threads, which have an advantageous effect on the cushioning property of the press cushion 1.
- the coatings 6 and 7 can contain heat-conducting fillers, for example in the form of metal powder.
- the press pad 1 described is particularly suitable for use in high-pressure presses which are to be used under clean room conditions, since even with strongly changing pressure loads and temperature fluctuations and resulting relative movements between the press pad 1 and the heating plate or the press plate, there is no abrasion of fibers from the tissue 2 is to be feared.
