Definitions

  • the invention relates to a plasterboard with coated Glass fleece layer, with at least one side of a plate core is covered with the glass fleece layer, the plate core Apply a calcium sulfate coating on the opposite side is, in the core mass forms the plate core and on the one hand penetrated into the glass fleece layer and coating compound forms the calcium sulfate coating and on the other hand has penetrated into the glass fleece layer where the coating mass is formed on the basis of a calcium sulfate and contains organic binder and in which the core mass is formed from calcium sulfate dihydrate, the calcium sulfate coating including glass fleece layer on the plate core at any point across the plate level with a right angle lifting strength measured at the plate level is and the plasterboard in the shortly after the state of manufacture is present.
  • the plasterboard is in an unprocessed condition and the A certain setting behavior can be assigned to coating compound.
  • a plasterboard of this type is essentially known (DE-OS 39 37 433). As is usual with plasterboard, this is Core mass formed on the basis of calcium sulfate dihydrate.
  • the coating composition consists of an at least partially inorganic binder set with water, under other from plaster. About setting degree or setting speed nothing is said about the mixture. Additions to the setting the setting speed of the plaster are not intended.
  • the plasterboard at issue here has the Advantage that a subsequent filling of the surface is eliminated and this surface is coated directly with emulsion paint, Wallpaper, tiles or mats can be covered.
  • the plasterboard is made by first laying a glass fleece sheet unilaterally with a set mixture from a inorganic binders, e.g.
  • Calcium sulfate hemihydrate and Water coated after partial setting and drying the coating rolled up and then with the uncoated Side with a pasty mixture that can be set a mixture based on calcium sulfate hemihydrate and water is brought into contact so that it Mixture only partially penetrates into the glass fleece while doing so after the plaster has set one with a coated Glass fleece-laminated plasterboard is created.
  • the coating composition sets quickly. No information is given on the extent of the at least partially existing binding. It is also not specified that the core composition and the coating composition have contact with one another in the glass fleece layer. If a gypsum building board of the type mentioned at the outset is to be useful in practice, then the quality of the bond from the calcium sulfate coating to the board core is important. The quality of this composite can be described by the lifting strength, which indicates the force / area with which a measuring disc adhered to the coating is pulled until the composite is destroyed. According to experiments with the known plasterboard of the type mentioned, a lifting strength of 0.1 N / mm 2 is not sufficient for the practical use of the plasterboard.
  • Delaminations or internal splitting can occur in the glass fleece layer, which is a considerable disadvantage particularly when applying heavy coatings such as heavy paper or textile wallpapers or ceramic tiles.
  • To remedy this disadvantage there is no other option than to fill the surface with a suitable filler in a thin consistency so that it penetrates deeply into the fleece, thus strengthening the surface and improving the bond to the gypsum core. This means an additional cost-intensive operation on the construction site.
  • the coating causes glass fiber abrasion on the outer surface the plasterboard prevented. If the plasterboard is cut or drilled, but then occurs on the Processing points fiberglass abrasion in a considerable Scope on.
  • a non-woven area in which the non-woven fibers are not enveloped by mass is not enveloped by mass.
  • the coating compound relatively brittle and brittle, which can sometimes already on the wound rolls of the coated Fleece shows that when processing, i.e. when drilling and Saws, glass fibers from the fleece, initially from coating material are enveloped, released. At the processing points Glass fiber abrasion therefore occurs disadvantageously.
  • the gypsum building board according to the invention solves this problem, characterized in that the calcium sulfate of the coating composition is not or almost not set and that the core composition is brought into contact with the coating composition almost continuously so that the lifting strength is at least 0.15 N / mm 2 is.
  • the coating mass is tough and strong and does not release glass fibers. Because the core mass almost in contact with the coating compound brought, there are no more non-woven fibers that are not are enveloped by mass.
  • the practically fiberglass-free The new plasterboard also makes the surface for the Suitable for ventilation ducts and cable ducts. The extent of penetration of the glass fleece layer with Core mass or the application of core mass to coating mass can by the improved lifting resistance specify at every point of the calcium sulfate coating.
  • the plasterboard according to the invention has excellent Coating properties, so that even heavy Coating materials such as Wallpaper, tiles or Mats, a firm and permanent bond with the plate come in without first filling or any other elaborate treatment of the surface would be required.
  • the bond quality is particularly increased in that the Calcium sulfate of the coating composition as a nucleating agent for the Gypsum formation of the core mass is used. This creates the Connection point between core mass and coating directional growth of a plaster layer, which extremely improves adhesion works (epitaxy).
  • the slow setting speed is within the scope of the invention usually given when the coating material is on the start of stiffening according to DIN 1168 is at least 1.5 hours and a maximum of 6 hours. Especially It is expedient and advantageous if the stiffening begins the coating mass at least 2.5 hours and / or is a maximum of 5 hours. Proven in this setting time range the invention is particularly good in practice.
  • the calcium sulfate of the gypsum board not yet processed is not or almost not set; the Degree of rehydration of the coating mass is ⁇ 5%, i.e. that a maximum of 5% of what was initially planned when switching on Calcium sulfate converted to calcium sulfate dihydrate to have. As a rule, however, the calcium sulfate is the coating material up to a maximum degree of rehydration 2% not tied.
  • each other the core mass and the coating mass in the glass fleece layer almost continuous.
  • the interface between the core mass area and the coating mass area is partially formed from nonwoven fibers, so that in this Area of contact between the core mass and coating mass cannot take place.
  • the Gypsum body of the core through the usual addition of air entraining agents and by evaporating the excess Mixing water is porous during drying. To that extent it doesn't help the degree of touch between Core mass and coating mass by proportions of one Separation area between core mass area and coating mass area specify. The extent of the touch is therefore described by its resistance to lifting.
  • the core mass is brought into contact with the coating mass in such a way that the internal strength of the system, expressed by the lifting strength, is at least 0.15 N / mm 2 at every point. It is particularly expedient and advantageous if there is an average lifting strength of at least 0.20 N / mm 2 .
  • the plate according to the invention proves particularly well in practice at this limit value of the lifting resistance.
  • the coating composition Calcium sulfate is hemihydrate and additives contains a slow setting speed of the calcium sulfate hemihydrate cause.
  • calcium sulfate hemihydrate is achieved by the additions that the coating mass of the gypsum building board not or almost is not set.
  • the calcium sulfate hemihydrate is more effective Stucco.
  • additives in the form of retarders include e.g. Citric acid and protein hydrolyzates.

  • the Limestone flour is a filler.
  • the condenser is e.g. Lignin sulfonate, a naphthalene sulfonic acid condensation product or a melamine resin.
  • the Coating composition contains a plasticizer.
  • the plasticizer is only in small quantities, e.g. maximum 5% by weight available and e.g. a polyacrylate or a styrene / butadiene.
  • the plasticizer makes the coating compound plastic and flexible, which is their ability to make the fibers permanent and firm to envelop, improved.
  • the calcium sulfate is a calcium sulfate anhydrite which is fine-grained with a grain size of ⁇ 200 ⁇ m , preferably ⁇ 63 ⁇ m and is partially capable of setting.
  • this special anhydrite can be provided as a plaster coating on the glass fleece layer.
  • This anhydrite has an advantageous ability to penetrate the fleece surface and forms an optimal bond with the binder and fleece.
  • the anhydrite preferably has a grain size average d 50 between 8 and 12 ⁇ m .
  • the coating mass when starting, regardless of added water has the following composition: At least 94% by weight calcium sulfate anhydrite, 0.01-0.8 % By weight cellulose ether, 0.01-1.0% by weight plasticizer and maximum 0.2% wetting agent.
  • the organic binder which in the present case in the Coating mass is provided, e.g. Polyacrylate or Styrene acrylate.
  • Organic binders deteriorate in the Rule the fire behavior and increase the toxicity of the resulting Smoke gases in the event of a fire.
  • Plasterboard can contain the binder proportion relatively be kept low. Particularly useful and advantageous so it is when the organic binder is less than 6% by weight of the dry coating composition.
  • the calcium sulfate that has not set or has not set, but is still reactive the coating composition thus enables a reduction the proportion of organic binder.
  • the coating composition up to 40% by weight aluminum hydroxide or boric acid admitted. This ensures that the Plasterboard meets the criteria for building material class A1 according to DIN 4102 fulfilled.
  • the abrasion resistance is determined on the basis of this to DIN 53109, "Testing of paper and cardboard: determination of abrasion using the friction wheel method "and ISO 4586-2 "Abration resistance of decorative laminated sheets.”

  • Each friction wheel comes with an additional weight loaded by 500 g.
  • the friction wheels are left during the test with the emery paper S-33 for 10 turns on the Act on the surface of the plate. After that the abrasion is through Determination of the weight difference determined.
  • plasterboard according to the invention Another advantage of the plasterboard according to the invention is that the resistance to lifting off after further surface treatment (primer, paint, wallpaper or plaster) is increased.
  • Plates of a manufacture according to the invention have an average lifting strength of 0.34 N / mm 2 after production, the minimum value from six measurements across the plate width being 0.23 N / mm 2 .
  • Part of the boards is painted with an aqueous dispersion primer, the other part is coated with a thin plaster based on gypsum.
