Definitions

  • Such a roof construction frequently includes the use of a metal, concrete or wooden underdeck or substrate upon which a mineral board is bonded, followed by three or four layers of felt and finally the asphalt or tar.
  • the tar is applied at approximately 400°F., in order to keep it fluid, which causes damage to the more energy efficient insulating boards such as styrofoam, and urethane board stock. Melting of these high energy efficient layers not only decreases the efficiency but causes channels for moisture which may produce severe roof damage and possible leakage.
  • This method includes steps of applying a layer of an adhesive to a substrate, the adhesive comprising a heated mixture of a polyurethane adhesive and an isocyanate curing catalyst admixed in a proportion to permit curing the adhesive at a temperature less than 140 °F., positioning insulation board on the substrata prior to curing the adhesive and curing said adhesive.
  • the insulation board is positioned on the adhesive after from one to about ten minutes after the adhesive layer is applied to the substrate.
  • the adhesive and the catalyst are admixed at a substantially equal viscosity to permit total and quick mixing. Simply, the adhesive and the catalyst are heated separately to control their viscosities, whereby at the mixing stage, the viscosities are essentially equal.
  • a gas producing agent in the adhesive to cause cellular formation of the adhesive upon curing.
  • a gas producing agent in the adhesive to cause cellular formation of the adhesive upon curing.
  • One preferred method is to include a quantity of fluorocarbon added to the mixture during the admixing step.
  • Another method which is preferred is to include a quantity of water admixed with the adhesive and catalyst for reaction therewith to form carbon dioxide.
  • a proportion of the mixture comprises approximately 50 to 70 parts by weight of the polyurethane and 30 to 50 parts by weight of the catalyst. Most preferred is a proportion of about 6O parts by weight of the polyurethane for every 40 parts by weight of the catalyst.
  • polyurethane adhesive of the present invention is initially sprayed onto the metal, wood or cement substrate to cover the surface of the substrate.
  • Polyurethane adhesives are very fluid at the temperatures used herein and therefore flatten to conform to the surface to which it is applied.
  • any insulation board can then be applied immediately upon application of the adhesive.
  • a second layer of adhesive on the top of the insulation board can be applied to bond the next layer, which can. be insulation board, particle board or felt.
  • a layer of the adhesive can be applied to bond the next layer, which can be insulation board, particle board or felt.
  • a layer of the adhesive can be piaced on the insulation material to bind it to the next layer to be added. Because the adhesive will adhere to the insulation board being applied during a period of from about one to about ten minutes or even more, one person can spray a large area and then apply the insulation board over this entire area.
  • a foamable polyurethane adhesive resin has been found to be acceptable.
  • a preferred adhesive is polyurethane adhesive 821WB, manufactured by Witco Chemical Company, New Castle, Delaware. This is a hydroxy terminated polyether resin.
  • any of the isocvanate catalysts may be employed but particularly preferred is isocyanate catalyst 821WA, also manufactured by Witco Chemical Company.
  • the two components, the adhesive and the catalyst are maintained in separate tanks.
  • a positive displacement pump the two components are transferred to a heater, then through a heated hose to a mixing spray gun which mixes, disburses, and gasifies the components to produce a cellular adhesive.
  • the presence of water in the mixture of adhesive and catalyst will cause the formation of carbon dioxide during the cure, to produce a cellular adhesive.
  • a fluorocarbon may be added during the admixing step to produce Lhe cellular product.
  • a preferred means of distributing the adhesive is the use of a spray gun.
  • the spray guns have a plurality of conduit elements to receive the catalyst and the adhesive and carry the same to a mixing chamber for intimately mixing the same and also forming the mixture into a gaseous state for spraying.
  • CMF ing spray gun provides airless atomization of the product.
  • This gun is manufactured by the Gusmer Corporation, Old Ridge, New Jersey, and is a preferred means for spraying the catalyst and adhesive mixture.
  • the urethane adhesive and the isocyanate catalyst were combined in various ratios ranging from about 50 parts to 70 parts by weight of the polyurethane and from about 30 parts to about 50 parts by weight of the isocyanate catalyst. All of these formulations performed adequately in bonding various insulation boards to substrates. Particularly preferred the formulations were in the proportion of polyurethane is about 60 parts by weight for every 40 parts by weight of catalyst.

Abstract

Procede et produit obtenu par ce procede de liaison d'une plaque isolante sur un substrat. Le procede consiste a appliquer par atomisation une couche d'un adhesif (qui peut etre mousse par de l'eau ou un fluorocarbure) sur un substrat, positionner la plaque isolante sur le substrat dans la position desiree avant la polymerisation de l'adhesif, et polymeriser l'adhesif. L'adhesif consiste en un melange chauffe d'un adhesif de polyuretane et d'un catalyseur de polymerisation d'isocyanate qui sont melanges avec des viscosites sensiblement identiques en une proportion permettant la polymerisation de l'adhesif a une temperature inferieure a 140 F. La plaque isolante est positionnee sur l'adhesif pendant un temps compris entre une et dix minutes environ apres atomisation de la couche adhesive sur la surface du substrat.
