Definitions

  • the invention relates to a nonwoven or fabric-based cover sheet material for the production of sheets provided with cover sheets on both sides from liquid or liquid-containing starting components, in particular for the production of gypsum boards and polyurethane (PU) rigid foam boards and their use in a continuous board production plant.
  • a nonwoven or fabric-based cover sheet material for the production of sheets provided with cover sheets on both sides from liquid or liquid-containing starting components, in particular for the production of gypsum boards and polyurethane (PU) rigid foam boards and their use in a continuous board production plant.
  • Panels provided with cover layers on both sides are widely used as components such as roof elements and for heat and impact sound insulation as well as packaging material.
  • nonwoven or woven webs as cover sheet materials, such as nonwovens or woven fabrics made of cellulose fibers, polyester fibers and, in particular because of their non-flammability, glass fiber nonwovens or woven fabrics.
  • cover sheet materials such as nonwovens or woven fabrics made of cellulose fibers, polyester fibers and, in particular because of their non-flammability, glass fiber nonwovens or woven fabrics.
  • core material such as the polyurethane foam
  • the bond between core and cover sheet material made of paper or film was always problematic.
  • nonwoven and woven materials have not been able to establish themselves as cover layer materials because the liquid components pass through the spaces in the nonwoven or woven fabric and in turn lead to sticking to the plate tapes.
  • Such liquid or liquid-containing starting components are in particular in the production of PU hard foam, but also in the case of urea-formaldehyde foam materials in which the starting materials react chemically or set and in the manufacture of plasterboards that set hydraulically.
  • cover sheet material which does not have the disadvantages outlined above, which enables the continuous production of sheets from liquid starting components without them passing through the fleece or fabric and sticking to the sheets or webs of the sheet-making system.
  • cover layer material is said to continue in fire behavior if possible correspond to building material group B2 or B1, but if possible even to building material group A2. It should also be resistant to hot bitumen, so that the top layer is not destroyed during the commonly used bituminizing, for example a flat roof, and no blistering, ie partial separation between the top layer and rigid PU foam, occurs.
  • a cover layer material with the characterizing features of the patent claim, which is characterized in that the nonwoven or woven fabric has a coating on one side of 70 to 94% by weight of a powdery inorganic material and 5 to 30% by weight of a binder, the powdery inorganic material in the coating composition preferably even makes up 80 to 94% by weight of the total coating.
  • Percentages of 50 to 70% by weight of inorganic material are concentrations of solids as are customary in coating and coating compositions.
  • Such conventional coating compositions with a high proportion of binder and liquid are not suitable for the purpose pursued by the invention because liquid and binder penetrate through the fleece or fabric and lead to the feared adhesion to the plate tapes of the continuous plate system.
  • the considerable amounts of liquid to be removed also lead to bubbles and shrinkage during the drying process and the coating does not dry without cracks.
  • a preferred method for producing the cover sheet material is to use a coating composition with a very high solids content, preferably from 70 to 80% by weight. Surprisingly, this coating can still be applied with a doctor device. It is expediently dried with hot circulating air and results in a perfectly closed coating without bubbles, shrinkage or cracks.
  • top layer material according to the invention is that the unusually high proportion of inorganic material makes the fleece or fabric impermeable to the liquid starting material becomes an integral part, thereby maintaining the open structure of the nonwoven or woven fabric on the back and thus ensuring a good anchoring of the cover layer material with the core material of the plate during the subsequent formation or foaming.
  • the high proportion of inorganic material also has the effect that a PU rigid foam sheet provided with this top layer material is resistant to hot bitumen, for example of 180 degrees, the top layer is not destroyed and no blistering occurs between the top layer and the rigid PU foam.
  • the high proportion of inorganic material further reduces the flammability compared to previously known materials.
  • inorganic-based binders such as water glass
  • organic-based binders in particular plastic-based
  • plastic-based are suitable as binders. Since water glass as a binder makes the top layer quite brittle, blends with binders based on plastic are also recommended.
  • Inorganic binders have the advantage that they further reduce the flammability.
  • the plastic-based binders are preferably used as plastic dispersions with a solids content of 35 to 70% by weight.
  • Particularly suitable are polyvinyl chloride and polyvinylidene chloride, which have the advantage of being flame retardant, and copolymers and terpolymers of vinyl acetate with maleic acid and acrylic acid.
  • Particular preferred because of their good binder properties over the inorganic coating constituents styrene-butadiene copolymers and polymers or copolymers of acrylic acid or methacrylic acid.
  • the amount of plastic dispersion used depends somewhat on the solids content, and in order to keep the energy required for drying the coating low, the solids content is as high as possible.
  • the most diverse powdery substances are suitable as inorganic material, in particular those based on minerals, such as silicates, clays, etc. Because of its easy accessibility and therefore reasonable pricing, calcium carbonate has proven to be particularly preferred.
  • aluminum hydroxide or aluminum oxide hydrate is particularly recommended as the inorganic material, with which the flammability level A2 can be achieved.
  • the inorganic material consists of a mixture of 10 to 50% by weight calcium carbonate and 90 to 50% by weight aluminum hydroxide or aluminum oxide hydrate for the coating.
  • the cover layer material and the PU rigid foam sheet covered with it become more flame-resistant, the higher the proportion of aluminum hydroxide or aluminum oxide hydrate.
  • the coating expediently also contains certain proportions of organic or mineral dyes, in order to thereby identify different grades of the plate, for example with regard to the fire behavior.
  • organic or mineral dyes in order to thereby identify different grades of the plate, for example with regard to the fire behavior.
  • coloring the cover material with soot has proven to be preferred, because even small amounts cover the entire surface.
  • the fleece or fabric used for the top layer material expediently has a basis weight between 35 and 350 g / m 2, preferably from 40 g / m 2 to 150 g / m 2, and the application weights of the coating are expediently between 150 and 450 g / m 2, these weights being in to a large extent depending on the intended use, the thickness of the core material, etc. Factors are dependent. Glass fiber fleece or woven fabric has proven particularly useful as a nonwoven and woven material, since it is not flammable. An organic-based nonwoven and woven material is expediently used. Because of its good strength, a polyester fiber fleece is preferred. When covering material for plasterboard expediently used both fleece and a mesh fabric together, because this can significantly reduce the susceptibility to breakage of the plasterboard. By using fleece and mesh together, the longitudinal and transverse strength can generally be considerably increased.
  • cover layer material is particularly preferred for the production of plates provided with cover layers on both sides in a continuous plate production system with upper and lower belt. It is of course also suitable as a lamination material for subsequent lamination, for example on polystyrene foam sheets cut out of a block of foamed polystyrene, the uncoated nonwoven or fabric side also being available here for the good bond between the cover layer material and the core material via the lamination material.
  • a coating material made of CaCO powder with a statistical mean grain size of approx. 10 ⁇ m and a polystyrene-butadiene dispersion with a solids content of 57% by weight is added to a glass fiber fleece with a weight per unit area of approx. 60 g / m2 in a knife coater 1.5 g of conventional auxiliaries such as defoamers, wetting agents and preservatives are applied, the solid matter total coating mass is approximately 75% by weight.
  • the proportions of CaCO 3 powder and plastic dispersion in the coating composition are selected so that after drying with hot circulating air in a drying tunnel, the coating is 92% by weight of inorganic material and 6.5% by weight of binder and the rest consists of auxiliaries.
  • the coating quantity is 250 g / qm dry.
  • a cellulose-based fleece which is flame-retardant and has a weight of 50 g / m2, is applied in a knife coater with a coating composition of aluminum hydroxide, calcium carbonate and a plastic dispersion of a terpolymer of vinyl acetate, maleic acid and methacrylic acid ester with a solids content of 50% by weight % and 3 g of the usual auxiliaries coated, the total solids content of the coating composition being approximately 73% by weight.
  • the proportions of aluminum hydroxide, calcium carbonate and plastic dispersion in the coating composition are selected so that after drying with hot circulating air in a drying tunnel, the coating consists of 60% by weight of aluminum hydroxide, 22% by weight of calcium carbonate and 15% by weight Binder, the rest of the auxiliary materials.
  • the amount of coating is approx. 250 g / q m atro.
  • a coating of 25 g aluminum hydroxide, 43 g calcium carbonate, 4 g titanium dioxide, 8 g of a plastic dispersion is applied to a nonwoven made of polyester fibers with a basis weight of 40 g / m2 a terpolymer of vinyl acetate, maleic acid and a methacrylic acid ester with a solids content of 57% by weight and about 1 g of common thickening, wetting and preserving agents and 23 g of water were applied in a knife coater and dried with hot circulation in a drying tunnel.
  • This top layer material is characterized by the use of titanium dioxide due to its white color and is used in the production of white panels that are used as wall cladding. The amount of coating on the dried top layer is approx. 270 g / m2 dry.
