Definitions

  • the present invention relates to an improved screening body and a method for preparing the same.
  • the screening body for a screening arrangement has improved properties in terms of ea. weather resistance, UV resistance and lamination properties.
  • Screening bodies are traditionally used for screening an aperture of a building structure, most often the light-admitting aperture of windows, but also of doors and other building openings. They are either installed to extend substantially vertically in a building façade, in an obliquely positioned roof window installed in an inclined roof surface, or as a horizontally extending cover for openings in a horizontal surface. When not screening the aperture, the screening body is normally rolled up on a roller bar accommodated in a top element of a screening arrangement.
  • the screening bodies can be used to block access to the aperture, to prevent light accessing the aperture and or/to help to moderate the temperature within a building.
  • conventional screening bodies have a layered structure in which metal strips are bonded to a fabric web.
  • One such system and a method of producing a metal foil - textile combination, particularly for use in roller shutters, is disclosed in EP1048817 .
  • the shutter slats are affixed to the web of the fabric using an adhesive.
  • the document discloses that to manufacture a roller shutter, adhesive is applied at the contact surface of the metal profile or the woven fabric.
  • the article is then shaped into a semi-finished product.
  • the semi-finished units are later assembled, with the metal profiles and the woven fabric pressed against each other at their contact surfaces.
  • the adhesive is activated and set by heating and cooling under pressure.
  • screening devices may be exposed to high and low temperature extremes.
  • High temperature exposure and moisture exposure can cause accelerated degradation of the screening device as it promotes processes such as hydrolysis and oxidation within the components.
  • Low temperature exposure can cause moisture trapped within the screening device to freeze.
  • the expansion encountered as the water freezes can add stresses to the construction and can result in failure of parts of the screening device, particularly around adhesive interfaces.
  • moisture can also lead to further problems with screening devices.
  • water can cause hydrolysis of polymeric components as a result of the interaction of water molecules with the polymers thereby resulting in a breakdown of the molecular chains.
  • UV radiation can also affect the screening devices, particularly as a result of polymer breakdown. UV radiation can stimulate the oxidation process which in turn can create free radicals which can cause breakdown of the polymer chains.
  • air pollution and salt in the air particularly in coastal environments, can increase rates of corrosion of the metallic components of screening devices.
  • a screening body for a screening arrangement including a top element defining a longitudinal direction, said screening body comprising a plurality of slats and a fabric layer having a top surface and a bottom surface, each slat extending in a longitudinal direction between two end edges and having first and second side edges parallel to the longitudinal direction, the screening body being adapted to be wound up in and rolled out from said top element in a direction perpendicular to said longitudinal direction to a screening position in which the screening body defines a general screening plane; in which each of the slats is composed of at least one metal strip connected to the fabric layer, the screening body being characterised in that the at least one metal strip is coated on at least the side facing the fabric layer and that an adhesive layer binds the metal strip to the fabric layer.
  • the combination of the coating on the at least one metal strip and an adhesive composition used to bind the metal strip to the fabric layer results in a screening body that has improved properties.
  • the metal is both protected from the adhesive and also primed to form a stronger bond with fabric through the adhesive.
  • the at least first metal strip is arranged to contact the top surface of the fabric layer and a second metal strip is arranged to contact the bottom surface of the fabric layer.
  • the screening body may have greater rigidity and strength.
  • the at least one first metal strip comprises aluminium.
  • the at least one metal strip may comprise an alloy having an Al content in an amount of at least 90 wt% or more preferably at least 93 wt%, most preferred at least 95 wt%.
  • the coating of the at least one metal strip on at least the side facing the fabric layer may comprise epoxy, polyethylene, polyester, polyurethane, acrylic or melamine.
  • the coating is not thermoplastic and preferably the coating is epoxy based. It has been observed that using coatings comprising epoxy groups gives rise to screening bodies with good adhesion properties to the aluminium and strong resistance to delamination, preferably the epoxy coating has aromatic groups.
  • the metal strip comprises additional layers such as primers etc.
  • the coating is a layer of the metal strip that faces the fabric layer.
  • the metal strips may have further coatings such as paint.
  • the adhesive composition may comprise thermoplastic polyurethane or polyethylene terephthalate. More preferably, the adhesive composition comprises an aliphatic thermoplastic polyurethane, even more preferred an aliphatic polyether polyurethane.
  • the adhesives are resistant to degradation, offer strong adhesion and are capable of percolating through the fabric.
  • the adhesive layer may be applied to only one side of the fabric.
  • the adhesive is applied to the bottom surface of the fabric layer facing the inside of a building when in use. Thereby the end product will have an improved appearance.
  • the adhesive composition may additionally comprise and/or possess a UV stabiliser.
  • the adhesive layer may be applied to the top surface of the fabric layer facing the exterior side of a building when in use. This embodiment is particularly preferred when the fabric layer is not UV stable, the adhesive layer comprising or being an UV stabilizer offers protection from UV light.
  • the adhesive layer is only applied to one side of the fabric layer, the adhesion of one and/or two of the at least one coated metal strips is sufficient since the adhesive percolates through the fabric.
  • the fabric layer may comprise any material known in the art, preferably the fabric layer is made of acrylic, polyester, polyamide, glass fiber or a glass fiber reinforced fabric, most preferred the fabric layer is acrylic.
  • the fabric layer is in a further preferred embodiment woven.
  • the fabric can be impregnated with and oil and/or water repellant such as fluorocarbon systems known in the art.
  • the porosity of the woven fabric is in the range of 50 to 500 mm, preferably 100 to 200, even more preferred 130 - 135, such as 133 when measured according to the Schmerber test in accordance to ISO 811. It is currently believed that the porosity or density of the fabric is important for improved adhesion. In some embodiments the fabric has a porosity that allows light through whilst the adhesive layer provides the darkening effect.
  • the fabric layer comprises acrylic or polyester
  • the at least one first metal strip comprises aluminium in an amount of at least 90 wt%
  • the adhesive composition comprises a thermoplastic polyurethane and the coating comprises epoxy.
  • the fabric layer is heated prior to being provided in step i. or that an adhesive composition is applied to the fabric under heating and is preferably allowed to cool down before being provided in step i. i.e. before another adhesive layer is applied to adhere the metal strip to the fabric layer.
  • an adhesive composition is applied to the fabric under heating and is preferably allowed to cool down before being provided in step i. i.e. before another adhesive layer is applied to adhere the metal strip to the fabric layer.

In further embodiments the adhesive is provided by extrusion, of e.g. a granulate, and said extruded adhesive is brought into contact with the fabric layer in step ii. The extrusion is preferably an integrated part of the method.
  • step iii. and vii. takes place at the same temperature, preferably in the same heating unit.
