Definitions

  • the invention relates to a flat, textile fiberglass material, which is characterized in that the front side forming the visible side and the back are provided with a specific coating of polyurethane.
  • Flat, textile fiberglass material that can be used as a wall or ceiling covering is known in the art. Due to the excellent range of properties find such flat textile fiberglass materials as semi-finished textile and textile finished products extensive application. For example, materials made of glass fibers are waterproof, hygienic, easy to clean and are available in many interesting structures to choose from.
  • the excellent properties of the flat, textile glass fiber materials known in the prior art are essentially determined by the glass fiber material itself, whereby a high tensile strength can be achieved and cracks can be bridged. Another advantage of the glass fiber materials is the fact that they are fire resistant and ensure easy and uncomplicated handling.
  • Textile glass fiber materials also show good abrasion resistance and can be produced by a surface coating in the form of brushing, for example by means of emulsion paint, in a variety of optical design. Therefore, flat, textile glass fiber materials in the form of wallpaper, especially for highly stressed areas, such as entrance areas, staircases, corridors, sanitary areas, hospitals, medical practices, department stores, lounges, etc., are particularly suitable.
  • the GB-A-1 184 563 a pre-glued nonwoven wallcovering made of glass fibers with two different coatings on both surfaces and a starch adhesive.
  • Coated glass fiber materials are furthermore known from GB 2054407A, WO 00/41584 and FR 2287337.
  • vinyl wallpapers are only half as strong in tensile strength as fiberglass wallpapers and that outgassing of additives and plasticizers must be expected.
  • a further object of the present invention is to provide a corresponding production method for such a textile highly stressable flat fiberglass material.
  • the visible side forming a front side and the back side of a flat, textile glass fiber material have a coating which contains and / or consists of polyurethane (PU).
  • PU polyurethane
  • the dry mass of PU in g / m 2 on the visible side coating has a smaller dry mass than the backside coating.
  • the dry mass for the visible side coating are between 10 to 40 g / m 2 and for the backside coating, again based on the dry mass, of 20 to 50 g / m 2 , wherein, as already stated above, it is essential that the dry matter in the visible side coating is smaller than in the backside coating.
  • the coating on the visible and rear side is a coating which contains PU / starch and / or consists thereof.
  • a PU / starch coating is applied to the visible and rear side, wherein then, based on the dry mass on the visible side, a ratio of starch to PU of 0.5- 1.5: 1.8-5, preferably 1: 3.5 and on the back a ratio of 0.5-1.5: 3-7, preferably 1: 5.5, in each case based on the dry mass, is maintained ,
  • a starch / PU coating is applied on the visible and the reverse side
  • this is achieved by using a selected starch / PU formulation.
  • a recipe consisting of a starch solution, i. from an aqueous starch solution, as well as from a PU solution / emulsion, wherein additionally thickener and crosslinker for polyurethane can be added.
  • Essential in the invention is always that ultimately results on the viewing and on the back of a PU coating with the specified characteristics.
  • the type of the flat, textile glass fiber material according to the invention comprises all materials known in the prior art and is not subject to any restrictions here.
  • the flat, textile glass fiber material comprises glass fiber fabric, glass fiber nonwoven fabric, glass fiber knitted fabric and glass fiber knit fabric.
  • the flat textile fiberglass material of the present invention is a woven product, i. a glass fiber fabric.
  • a glass fiber fabric can be made on a variety of devices as known in the art. For example, gripper looms or air-jet looms can be mentioned here.
  • the textile fiberglass material is preferably R glass, M glass, ECR glass, D glass, AR glass, but preferably E and C glass.
  • other fibers such as polyester, Kevlar or carbon fibers, to be present in addition to the glass fibers. The selection of the corresponding additional fibers depends on the application.
  • the textile glass fiber fabric in the weft and in the warp is formed from glass filament materials in the form of glass silk, glass staple fibers, textured glass silk and / or glass wands.
  • the invention further relates to a method for producing a flat, textile fiberglass material as described above.
  • the procedure is such that the visible side coating is applied, then dried, and after drying the visible side coating, a backside coating is applied.
  • the production method according to the invention thus takes place in a stepped process.
  • the coating material i. the polyurethane or the polyurethane / starch formulation through which roller system can penetrate into the open spaces between the intersections of the warp and weft threads.
  • a standard glass fiber fabric was used.
  • Such a standard glass fiber fabric consists of warp and weft with variable fineness, which can be composed of different types of glass and different glass yarns, as well as a base coat.
  • glass types in particular C and E glass can be mentioned in addition to all currently known types of glass.
  • glass yarns are glass staple fibers, textured glass silk, glass rovings and glass silk in question.
  • the fabric may be treated with different weaving techniques, e.g. Jacquard weaving technique, and with different types of weave, e.g. Canvas or twill weave. Through the weaving techniques, the use of different yarn counts and the different types of weave different patterns can be created.
  • the primer coating is like in the DE 10 2007 009 619 A1 described together.
  • the uncoated glass fabric has basis weights between 50 and 400 g / m 2 .

  • the end product weights resulting from uncoated glass fabric and base coating are between 100 and 500 g / m 2 .
  • a visible side coating is performed using a rotary screen printing method.
  • a perforated metal cylinder 1 with holes of a certain number and size can be used, this metal cylinder 1 having a doctor blade 2 and a doctor blade holder 3.
  • the glass fabric 4 to be coated is now, as can be seen in FIG. 1, guided vertically past the metal cylinder 1.
  • the perforated metal cylinder 1 with holes of a certain number and size and the doctor blade 2 or the doctor blade holder 3, which is also referred to as a template, is filled with the coating material 6.
  • the coating material 6 is designed in its physical properties, in particular in its viscosity, so that it can be pressed through the holes of the perforated metal cylinder 1.
  • the coating applied by the method described above is designated 5.
  • the metal cylinder 1 rotates in the same direction as the tissue is guided.
  • a coating formulation a formulation which consists of a starch solution, water, thickener, starch crosslinking agent, polyurethane and, if necessary, crosslinking agent for polyurethane.
  • the coating material to be applied is adjusted in its viscosity so that a problem-free application to the glass fabric. 4 is guaranteed.
  • the formulation for the visible side coating is adjusted so that ultimately a dry matter, determined in g / m 2 of starch to PU, from 0.5 to 1.5: 1.8 to 5 results.
  • a dry matter to starch ratio of 1: 3.4 resulted.
  • a drying which is preferably carried out in the form of a stepped drying.

  • the coating material 7 is then applied by the roller 8 to the fabric 4, ie in this case to the back.
  • FIG. 2 is the already coated visible side not shown.
  • Suitable formulations for the backside coating must be selected so that, based on the dry mass in g / m 2 , a ratio of starch to PU of 0.5 to 1.5: 3 to 7 can be maintained. In the embodiment as described above, a formulation has been chosen which has resulted in a coating having a ratio of 1: 5.5 for starch to PU.

  • the experimental setup was as follows. On a vertical wall were the samples to be examined, i. the fiberglass fabric, arranged. About this glass fiber fabric, a plastic wheel, as it is commonly used in hospital beds, stripped horizontally. The plastic wheel, which was attached to a movable test arm, was unrolled over the surface of the glass fiber fabric to be examined using a contact pressure, measured with a spring balance of about 11 kg. It was carried out 35 cycles per minute. It has been shown that during the tests, a surface temperature of about 35 ° C is formed.
