Definitions

  • the invention relates to a pressure compensation fabric, in particular press pad, for use in hydraulic Walkerpressanlagen, comprising metal filaments, both as warp and as weft threads of the press pad, and high temperature resistant elastomeric threads, the latter preferably with stabilizing core threads, wherein the elastomeric threads either as warp or as weft threads alternately with the metal threads are arranged.
  • Press pads are used in various types of press systems, such as the so-called one-day short-cycle presses for the lamination of particleboard, MDF or HDF boards with thermoset resins such as melamine, melamine-urea mixed resins or phenolic resins, but also in multi-floor high-speed presses. and low pressure presses for the production of high pressure laminate, compact and plywood boards.
  • press pads can be used in all press systems.
  • Such press pads are usually constructed in the form of a fabric, wherein the materials are resistant to high temperatures, since the operating temperatures in the press systems are partly above 200 ° C. Furthermore, they should, if possible, have a large recovery property with an intermittent pressure load and have a fast thermal conductivity.
  • Thermoset resins are very sensitive to pressure tolerances when forming surfaces on the aforementioned plate materials. Thus surface defects can arise due to unequal pressure distribution.
  • Known manner prevail in the coating systems considerable thickness tolerances, which add up from the press system, press plates and the respective pressed material.
  • the press pads therefore have the task to compensate for these thickness tolerances and to transmit the pressing pressure uniformly and over the entire surface of the material to be pressed, at the same time a rapid and uniform heat transfer of the hotplate temperature of the press plant is aimed at the pressed material.
  • the flexible upholstery fabric consists of a yarn of aromatic polyamide, which may be mixed with other gammaterials.
  • the textile fabric contains metal filaments, wherein the proportion between 0 and 70 wt.% Is to adjust the required thermal conductivity accordingly.
  • EP 0 713 762 A2 is a press pad for high and low pressure presses made of different materials.
  • a likewise known from the prior art press pad is from the EP 0 735 949 B1 known, wherein the warp threads and / or weft threads have a silicone elastomer and in the fabric metal wire in the form of full filaments or with silicone sheath are included.
  • a press pad consisting of a fabric comprising a substantial proportion of a blend elastomer prepared by crosslinking a mixture of a silicone rubber and a fluororubber or of a silicone rubber and a fluorosilicone rubber.
  • the proportion of fluororubber or fluorosilicone rubber should be at least 4% by weight, preferably 10% by weight.
  • the warp and / or weft threads contain metal threads.
  • a press pad known which is used for the production of printed circuit boards.
  • the known pad may comprise a woven fabric, a paper, a film or a sheet-like structure, which is combined as a layer with at least one further layer of a fluoroelastomer.
  • the fluoroelastomer should have a fluororubber component of the polyol curative system, a curative, a cure accelerator, and an acid acceptor.
  • Another press pad goes out of the EP 1 300 235 B1 out.
  • This is a metal mesh, consisting of core threads with stainless steel sheath and twisted copper wires with aramid core, wherein the metal fabric with a Silicone rubber coating is provided. To ensure heat transfer, the copper threads protrude from the silicone rubber surface.
  • the melamine resins are first low-viscosity fusible and flowable and then crosslink to insoluble, infusible hard, abrasion-resistant and thermally resistant plastics. This is called a so-called polycondensation, whereby water and formaldehyde is formed.
  • the resulting in the condensation reaction water and formaldehyde can not be released in vapor form, since the pressing pressure prevailing in the press, is above the vapor pressure of the water and also presses the two gas products in the film layer or in the support plate.
  • the flow time and the melt viscosity of the resin are determined essentially by the degree of condensation, the ability to react and the temperature and must be adjusted so that the vapor bubbles can migrate before the resin melt solidifies and the surface is formed. If these vapor bubbles can not diffuse sufficiently into the carrier plate, cloudy to milky surfaces develop. This haze is caused by the different refractive indices of the predominant materials.
  • the existing temperatures are relatively constant, so that the resin flow can not be influenced by temperature change, which naturally does not want to change the predetermined pressing times. Although the heat flow in all press pads is different in speed but uniform, no positive influence on the resin viscosity or the resin flow can be achieved.
  • the invention has for its object to propose a press pad, which ensures a better diffusion of the vapor bubbles and thus a transparent and closed melamine resin surface is achieved.
  • the liquid resin phase should be extended.
  • the object is achieved in that the thickness is determined in the non-compressed state of the press pad of the elastomeric threads and thus the contact points of the press pad with parts of the Edelpressstrom at moderate pressure build-up are first formed by the elastomeric threads, wherein the elastomeric threads are compressible such that at further Pressure increase up to the total pressure, further contact points are formed by the metal threads.
  • Advantage of the press pad according to the invention is a controlled heat flow in the manner of a pressure-dependent heat flow.
  • the heat flow takes place during this time essentially only by the elastomeric threads, since the metal threads are not yet in contact with the heating plate and the press plate. Since the viscosity or the degree of crosslinking of the resin is temperature-dependent, the liquid resin phase is extended until the metal threads of the press pad come into contact with the heat-conveying hot plate and the press plate by the increasing pressing pressure.
  • the press pad according to the invention thus allows a time-delayed increase in the prevailing at the surface of the press pad temperature to provide more time for flow of the resin over an extension of the "low-temperature phase".
  • the press pad according to the invention has metal threads both as warp threads and as weft threads, whereby the press pad is very dimensionally stable.
  • the high-temperature resistant elastomer threads are arranged either as warp threads or as weft threads alternately with the metal threads.
  • Either an elastomer thread and a metal thread can be arranged alternately, or in each case one elastomer thread and two or three metal threads, or vice versa, wherein the invention should not be limited to the aforementioned variants.
  • the diameter of the elastomer threads is at least twice, preferably three times, the diameter of the metal threads.
  • the ratio of the diameters of the elastomeric filaments to that of the metal filaments increases, the length of the liquid resin phase increases, and thus the period during which the vapors can diffuse into the paper web during the pressing operation.
  • too large diameters of the elastomer threads counteract the need for short pressing times.
  • the elastomer threads are advantageous for the elastomer threads to consist of high temperature resistant elastomers such as silicone rubber, fluorosilicone rubber, fluororubber, or a copolymer of the aforementioned rubbers.
  • the stabilizing core threads can consist of single filaments, and it is again advantageous if they are high-temperature resistant core threads, such as polyaramids such as Kevlar or Nomex filaments.
  • the elastomeric threads are provided with metallic core threads either of monofilaments or of stranded metal threads such as copper strands, brass strands, (noble) steel strands, etc.
  • the elastomer threads in the elastomer sheath may contain thermally conductive substances, such as metal powder.
  • Elastomers according to DIN 7724 are polymeric materials which behave entropy-elastically (rubber-elastic) in the service temperature range. Elastomers, also referred to as rubber (excluding hard rubber) or vulcanizates in German usage, are formed by crosslinking of rubbers by crosslinking in the majority of cases or by cross-linking copolymerization of low molecular weight starting materials. Elastomers can not be significantly deformed by heat or moderate pressure. In general, their tensile set remains below 2%.
  • FIG. 1 shows a metallic strand of individual stranded brass threads 2, this metal thread 1 being processed both as a warp thread and as a weft thread of a pressure compensation fabric 6.
  • FIG. 2 shows an elastomer thread 3 which consists of a core thread 4 and an elastomer sheath 5, for example of a copolymer fluorosilicone / silicone rubber.
  • the core thread 4 consists of stranded copper threads.
  • the elastomer thread 3 is processed as a weft thread of the pressure compensation fabric 6.
  • the upwardly cranked elastomeric threads 3 in the weft or the cranked metal threads 1 can be seen in the weft and in the warp of the press cushion fabric.
  • the elastomer threads 3 have a significantly larger diameter than the metal threads 1, wherein the diameter of the elastomer threads 3 is advantageously at least twice as large as that of the metal threads. 1
  • FIG. 4 shows a section through the press cushion according to the invention according to FIG. 3, which is arranged in a press installation between a heating plate 7 and a press plate 8.
  • the contact points of the press pad are initially formed at moderate pressure build-up only by the elastomeric threads 3.
  • the metal filaments 1 all, even at their extreme points ("wave crests") at a distance from the plane formed by the extreme points ("peaks") of the elastomeric filaments 3, whereby the thermal conductivity is initially lower. Only with further pressure increase up to the total pressure additional contact points 9 are formed by the stranded brass threads 2, so that then a faster heat flow is produced.
