Definitions

  • the present invention pertains to the field of sheets or films especially solar control films and solar control window shades made from such films which are susceptible to burning. More particularly, the present invention pertains to flame retardant films or sheets such as solar control films and solar control window shades made from such films which have desirable flame retardant characteristics without sacrificing the optical clarity and visible light transmission characteristics which are desired in this field of technology. The present invention also pertains to the field of compositions which can be used to form flame retardant adhesive layers and flame retardant optical layers in sheets or films especially solar control film structures and solar control window shades made from such film structures.
  • Polymeric materials are combustible and will easily burn when subjected to sufficient heat, e.g. , flame, in an oxidizing environment.

  • Solar control window shades are typically made from flexible transparent film or sheet material which includes one or more layers of optical coatings which are designed to block or reflect certain portions of the electromagnetic spectrum.
  • solar control window shades are typically designed to block or reflect infrared and/or ultraviolet light and reduce the amount of visible light which passes therethrough while maintaining some degree of visible light transmittance. It is particularly desirable in many applications to provide a solar control window shade which has the desired the blocking and/or reflecting characteristics while maintaining good optical clarity and visible light transmittance.
  • the combustibility of such window shades have become of great concern recently since such window shades are typically used indoors where they can become a fire hazard. In this regard some countries have set flame retardant criteria for such solar control window shades and the like.
  • Solar control window shades are generally made from a flexible transparent film structure which includes one or more layers of polyethylene terephthalate (PET). Generally an adhesive is used to bond together the PET films which are used to make the solar control window shade. In addition, the solar control window shade will also include one or more layers of coatings which are formulated and applied to provide the desired light blocking and/or reflecting characteristics.
  • PET polyethylene terephthalate

  • an organic solvent solution which can be used to form the optical coatings in the solar control film structure.
  • the organic solution which is used to produce the flame retardant optical coating contains organic solvent in which are dissolved compounds which, upon curing, form a flame retardant aery late coating.

  • the adhesive layer and optical coating layer used in the present invention does not adversely effect the transmission of visible light through the film structure nor does it hinder the optical clarity of the film structure such as by the development of haze.
  • visible light means light in the wavelength range of 400 to 750 nanometers.
  • optical clarit refers to film materials with low haze, e.g. , generally less than 25 % haze, more preferably less than 20% haze. Haze in an otherwise potentially optically clear polymeric material typically has the effect of scattering of visible light passing through polymeric materials. Thus, scattered visible light is a useful surrogate measurement for haze. For instance, a film characterized by 25 % haze will exhibit scatter of 25 % of the transmitted visible light In an optically clear polymeric film or composite of polymeric films, optical clarity is further manifest by the ability to distinguish shapes viewed through such films.
