Definitions

  • This invention relates to specular silver mirrors More particularly, it relates to a durable corrosion and ultraviolet-resistant silver mirror for use in solar reflectors Background Art
  • Insufficient weather protection and ultraviolet degradation are problems, which are encountered when using solar reflectors made of a flexible specular silver mirror When used outdoors, these mirrors must be durable and ultraviolet light (UN) resistant in order to retain their dimensional stability, aesthetic appearance, and specular-reflectance in the visible, ultraviolet, and near infra-red wavelengths Specular-reflectance is provided in a flexible silver mirror through a silvered composite lamina, having a thin layer of silver vapor-deposited on the surface of a flexible polyester substrate.
  • Silver is the preferred metal because its reflectivity is substantially higher than that of other metals, such as aluminum
  • the p ⁇ or art has focused on the application of advanced adhesives and protective films, layered over the polyester substrate and silver layer, to protect the mirrors from abrasion, weathe ⁇ ng, and ultraviolet degradation.
  • the peak transmission of this light is at 320 nm, and sunlight contains ultraviolet light at this wavelength.
  • the transmission of ultraviolet light through the silver layer degrades the underlying polyester substrate causing bubbles in the adhesives, commonly used to adhere the substrate to a rigid support. This degradation and bubbling reduces the aesthetic and specular functional properties of the solar mirror.
  • Corrosion inhibitors and UN absorbers incorporated into the adhesives or protective film coatings overlaying a polyester and silver mirror substrate, have been used to retain these functional properties.
  • corrosion inhibitors do reduce corrosion, they frequently impart an unacceptable color to the mirror, over time, and do not block the ultraviolet light.
  • ultraviolet light absorbers are incorporated into a protective polymer overlay, the rate of polyester support degradation is lessened, but silver corrosion is aggravated.
  • attempts have been made to isolate the corrosion inhibitor and ultraviolet absorber elements from the mirror's reactive components in order to eliminate these undesirable effects.
  • a corrosion resistant silver mirror wherein a corrosion inhibitor, and an ultraviolet absorber are each incorporated into separate thin overlays of an acrylate inter-polymer paint.
  • the specular reflective mirrors are formed by vapor-depositing silver over a polyester support film. Ultraviolet degradation of the polyester support, and consequent bubbling of the underlying adhesive, is reduced by incorporating UV absorbers in a second polymer coating that is applied over a first polymer coating, which incorporates a corrosion inhibitor. The first polymer coating is applied directly over the silver reflective surface.
  • the polymeric substrate a coextruded biaxially oriented polyester foil, comprises: (1) a polyethylene terephthalate lamina containing conventional slip agents to facilitate winding; and (2) a polyethylene terephthalate lamina containing no slip agent, which results in an optically-smooth exposed surface.
  • the silver specular reflective layer overlies the smooth surface, of the coextruded film, and is bonded thereto.
  • Layered over the silver is a first acrylate or methacrylate inter-polymer coating, having a 0.5 to 2.5% glycol dimercaptoacetate dispersant, which serves as a coupling agent, primer, and corrosion inhibitor. This coating weighs 1-4 g/ ⁇ r.
  • a second acrylate coating Overlying the first acrylate coating, is a second acrylate coating containing an ultraviolet absorber effective throughout the 300-400 nanometer range
  • the weight of the second coating is 4-8 g/m 2
  • Inclusion of the corrosion inhibitor and the UV absorber into separate layers is designed to keep the UV absorber out-of-contact with the silver, and to avoid any corroding effect
  • On the opposite side of the coextruded polyester support is a uniform coating, weighing about 10-15 g/m 2 , of a tacky and pressure-sensitive adhesive (95-5 isooctyl acrylate. acrylamide copolymer)
  • a conventional release liner such as a sihcone- coated polyester film, may be used to protect the adhesive p ⁇ or to use
  • the disclosure of U.S Pat. No 4,645,714 is incorporated by reference as though fully set forth herein.
  • Hutchinson discloses the use of corrosion inhibitors and ultraviolet absorbers in an adhesive, which is used to bond an abrasion and moisture resistant fluorocarbon protective coating over a polyester and silver mirror substrate.
  • the relevant embodiment, therein, desc ⁇ bes a corrosion and ultraviolet light resistant flexible reflective film, where the respective inhibitors and absorbers are incorporated into separate coatings of an adhesive.
  • a thin layer of silver is vapor-deposited on a flexible polyester support sheet, producing the specular silver surface
  • the adhesive is used to bond a fluorocarbon film, having an abrasion and weather resistant function, to the surface of the silver
  • the adhesive is applied in two separate layers
  • the first adhesive layer is adjacent to the silver deposit and contains a corrosion inhibitor
  • the second adhesive layer contains a UV absorber and overlays the first adhesive layer for use in bonding the fluorocarbon protective film to the silver surface
  • the use of adhesives to bond the fluorocarbon film to the silver surface is a required element, of this construction, because fluorocarbon films do not bond to metal surfaces
  • this construction is not without its deficiencies when used, over time, as a solar mirror Under ultraviolet light, the application of advanced adhesives (those incorporating UV absorbers and corrosion inhibitors) directly onto a silver substrate has resulted in degradation of the silver/adhesive interface When silver is adhered directly to acrylic films tunnel and delam ation failures have also occurred Moreover, fluorocarbon
