Definitions

  • the invention relates to mortar with mineral binders and coating materials with organic binders, in which a textile reinforcement is embedded.
  • these are very tear-resistant glass silk fabrics that are protected against attack by the alkali of the cement by a synthetic resin or silicone coating.
  • These fabrics intended for embedding in high-quality mineral plasters or synthetic resin plasters are also non-slip, i.e. that is, the points of contact of the threads are - usually with a synthetic resin - glued, so that the fabric is given a geometrically stable structure.
  • Fabric reinforcement is common in the top coating of external insulation systems, which have gained considerable importance over the past decade to save energy.
  • a single-layer external insulation consists, for example, of insulation boards made of rigid foam, in particular polystyrene, which are glued to the outer wall of the house and which have been given an upper coating of dispersion plaster. Due to the material-related shrinkage of the rigid foam panels and the effects of temperature and weather, considerable tension occurs between the insulation panels and the plaster coating. This can lead to this external plaster shearing off the insulation boards and to the formation of cracks in the top layer, particularly where the insulation boards abut. To avoid the formation of cracks, the reinforcement is provided with alkali-protected, sliding-resistant glass silk fabrics. In warp and weft, these glass fabrics consist of untwisted yarn or threads that have only received a protective twist of, for example, less than 30 turns per meter.
  • the glass fabrics used for reinforcement themselves contribute to the cracking of the coating because they can no longer carry out the shrinkage or expansion of the plaster if they are firmly embedded in it after it has hardened.
  • Glass threads have a high tensile strength, but they have poor transverse stability and therefore break easily when they are stretched or compressed. While the warp threads, due to their linen or leno weave, can undergo the compression, especially when the plaster layer hardens, and a change in length that occurs later, this is not the case with the weft threads made of practically inelastic glass silk. Rather, they act as a rigid stiffening reinforcement that resists any changes in length. During the compression, the weft blows off the mortar, which then tears across the weft. This means that vertical laying of entire webs also leads to vertical crack formation.
  • the invention provides a remedy by providing for mortars with mineral binders and coating materials with organic binders with a textile reinforcement from a saponification and sliding resistant, wide-mesh fabric or knitted fabric that the weft thread of the fabric or knitted fabric is a twisted yarn and the fabric or knitted fabric in the longitudinal and transverse direction, an elasticity of at least 3 0/0 and in both directions has a tensile strength of at least 1200 N per 5 cm width.
  • the fabric to be used according to the invention should consist entirely or predominantly of glass and / or carbon fibers.
  • the use of highly tear-resistant organic fibers, e.g. B. from polyamides, polyesters or aramids is possible to achieve special mechanical properties and can be done by using a blended yarn or a blended fabric.
  • Glass fabrics made from twisted twine are known per se and were used for special applications, for example in filter technology. Regardless of the particular application according to the invention, however, it is very unusual to use a simple warp in such a glass fabric, i. H. an untwisted yarn as a warp thread, but a twisted thread as a weft thread.
  • a glass fabric which is particularly suitable as a textile reinforcement of mineral or synthetic resin-bound coating material is made up, for example, of a leno strand of 136 tex per thread, ie the warp yarn has a yarn count of 136 tex.
  • the individual filaments usually have a diameter of 9 or 13 ⁇ m.
  • glass threads of the same fineness are turned up from, for example, 136 tex to 150 turns by Z rotation and then at least two of these threads are turned counterclockwise with about 135 turns, ie twisted.
  • This tissue preferably has a basis weight of 100 - 600 g / m2, an elasticity in the warp and weft directions of 3 - 10, in particular 3 - 6% and a tensile strength of 5 cm in the warp direction over 1800 N and in the weft direction over 1300 N.
  • a longitudinal and transverse elastic textile reinforcement z. B. for ceiling plasters or in particular for the top coatings of the rigid foam panels in the known external insulation systems, can also be a loose knitted fabric made of glass or carbon fibers.
  • Such a knitted fabric is characterized by 20 to 25% elongation in the longitudinal direction and an elongation in the transverse direction of up to 10%.
  • the glass fiber used to manufacture the knitted fabric can be twisted, but a protective twist is usually sufficient.
  • Such a full heat protection system has the following structure, for example.
  • Deposited polystyrene rigid foam panels with a density of 15 to 30 kg / m 3 and a panel thickness of 3 to 20 cm are attached to the load-bearing wall by gluing or with dowels.
  • a full thermal insulation system with a mortar or coating material 6, which is reinforced with an embedded mesh fabric 3, is shown reduced.
  • the detail shows an enlarged view of the mesh fabric 3 with a chain as a simple leno strand 4 and a twisted weft thread 5.
  • the hardened composite mortar 6 is first scrapped onto the insulation board 2 in strips 7, then the mesh fabric 3 is placed on it and pressed in by superficial pressing embedded the composite mortar. A decorative plaster 1 can then be applied.
