Definitions

  • Rigid polymeric foam insulation laminates have been used for many years by the construction industry. Uses include commercial roof insulation boards utilized under asphaltic built-up roof (BUR) membranes as well as under various single ply membranes such as EPDM rubber, PVC, modified bitumen membranes and the like . Other uses include residential insulation, as sheathing under siding, and as roof insulation under asphalt shingles and concrete tiles .
  • BUR asphaltic built-up roof
  • Such insulation often takes the form of a core polymeric foamed thermoset material such as polyurethane, polyisocyanurate, polyurethane modified polyisocyanurate (often referred to as polyiso) or phenolic resin, applied between two facing sheets .
  • a core polymeric foamed thermoset material such as polyurethane, polyisocyanurate, polyurethane modified polyisocyanurate (often referred to as polyiso) or phenolic resin
  • insulation boards are generally manufactured on production lines where a liquid core chemical mixture is poured over a bottom facer, foaming up to contact a top facer in a constrained rise laminator.
  • the reaction of the chemical mixture causing foaming is generally exothermic, as curing via polymerization and crosslinking occurs in the laminator .
  • the curing exotherm lasts well into the time the resulting rigid boards are cut, stacked and warehoused. The exotherm can continue for as long as 4 days and the mixture can reach temperatures as high as 325°F.
  • Desirable properties for the facers include flexibility, high tensile and tear strength and resistance to thermal degradation. Facer porosity should be low and the thickness of the facer coating should be sufficient to prevent bleed-through of the liquid chemicals prior to foaming. Additionally, facers should exhibit good adhesion to the core foam insulation and be inert to the effects of extraneous chemicals which may be present in the mixture, especially blowing agents that also behave as solvents . Blowing agents currently in use include chlorofluorocarbons like HCFC-141b and R-22 as well as hydrocarbons such as n-pentane, cyclo-pentane and iso-pentane .
  • the facer should provide mechanical stability as well as water and weather resistance since, upon installation, they may be exposed to persistent rain, high humidity, ultraviolet light and excessive heat. Additionally, the facers must be puncture and scuff resistant to survive being nailed and walked on. Withstanding temperatures up to 500°F, as encountered in hot asphalt applications , as well as resistance to the deleterious effects of adhesive solvents used in single ply roofing membrane applications while strongly bonding to the adhesives themselves are also important facer properties .
  • facer materials have included asphalt saturated cellulosic felts, fiberglass mats, asphalt emulsion coated fiberglass mats , aluminum foil/Kraft/foil, glass fiber modified cellulosic felts, glass mats onto which polymeric films have been extruded, and glass mats coated with polymeric latex/inorganic binder coatings.
  • asphalt- containing products are not compatible with PVC single ply roofing membranes.
  • Fiberglass mats are subject to excessive bleed-through of foamable core chemicals. Aluminum facers and foils reflect heat into the foam during processing which leads to disruption of cell structure, delamination and warping.
  • glass mats coated with polymer latex/inorganic binder mixtures have been found to be brittle; conversely, glass fiber modified cellulosic felts are susceptible to moisture absorption aggravating board warping in damp or wet environments .
  • U.S. Patent No. 5,001,005 describes a facing sheet composed of glass fibers and a non-asphaltic binder .
  • the facer contains 60-90% glass fibers, which high fiber content does not provide sufficient binder to close the sheet's pores or to provide desired sheet strength.
  • U.S. Patent No. 5,112,678 discloses a facer prepared by applying to a fiberglass mat a flowable polymer latex and an inorganic binder coating.
  • Another object is to provide a facer which exhibits superior adhesion to polyiso foam of an insulation board core material .
  • the non-asphaltic, non-cellulosic facer of the present invention comprises a dry, preformed fibrous mat substrate on which is coated a pre-frothed or pre-foamed composition containing a natural or synthetic thixotropic latex polymer, a surfactant and an inorganic mineral filler .
  • the composition may optionally contain up to about 15 wt.% of extraneous additives, which include a flame retardant, dye, thickener, porosity reducing agent, thermal and/or UV stabilizers and the like, to provide a foamed facer product having, on a dry weight basis, less than 50% fiber in the mat.
  • the preferred facer product contains 30 to 46 wt.% of fiber in the composition consisting of mat fiber with binder and latex in the coating mixture .
  • the foamed coating composition applied to the preformed mat contains on a dry weight basis between about 15 and about 80 wt.% of the thixotropic polymer latex, between 0.01 and about 80 wt.% filler, between about 0.5 and about 10 wt.% foam supporting surfactant and 0 to 15 wt.% extraneous additives.
  • the fibers of the mat employed in this invention include any of the non-cellulosic types, such as fibers of glass, polyester, polypropylene, polyester/polyethylene/teraphthalate copolymers, hybrid types such as polyethylene/glass fibers and other conventional non-cellulosic fibers .
  • Mats having glass fibers in random orientation are preferred for their resistance to heat generated during the manufacture of insulation boards and flame resistance in the finished product.
  • the fibrous mats of the invention generally of between about 10 and about 30 mils thickness, conventionally contain a binder which is incorporated during mat formation to fix the fibers in a self- sustaining solid web and to prevent loss of fibers during subsequent processing and handling.
  • binders include phenol- , melamine- and/or urea- ormaldehyde resins or mixtures thereof.
  • the mats having glass fibers in the range of from about 3 to about 20 microns, most desirably 10-18 microns, in diameter and a length of from about 0.25 to about 1.75 inch, most desirably a length of 0.75-1.5 inch.
  • the fillers useful in the present coating mixture include conventional inorganic types such as clays, mica, talc, limestone, kaolin, other stone dusts, gypsum, aluminum silicate (e.g. Ecca Tex 561) , flame retardant aluminum trihydrate , ammonium sulfamate , antimony oxide , calcium silicate, calcium sulfate, and mixtures thereof.
  • inorganic types such as clays, mica, talc, limestone, kaolin, other stone dusts, gypsum, aluminum silicate (e.g. Ecca Tex 561) , flame retardant aluminum trihydrate , ammonium sulfamate , antimony oxide , calcium silicate, calcium sulfate, and mixtures thereof.
  • Surfactants employed in the coating composition are organic types suitable for stabilizing latices , such as for example, ammonium salts of a Cio to C 22 fatty acid, e.g. ammonium stearate (STANFAX 320) .
  • One or more surfactants can be employed in the coating composition to promote the formation of foam and to maintain the foam structure of the coating before curing.
  • the latex component of the coating composition includes latex polymers of natural rubber as well as synthetic latices including copolymers of styrene and butadiene and acrylic based resins .
  • Representative examples of these are polyvinyl chloride, styrene/acrylic or methacrylic esters, ethylene/vinyl chloride and polyurethane , polyisoprene , polyvinylidene chloride , polyvinyl acetate/polyvinyl chloride and synthetic rubbers such as SBS, SBR, neoprene , etc. and any other thixotropic latex polymer and mixtures of the foregoing.
  • the mat coating mixture of the invention is obtained from a frothed or foamed 15-80 wt.% aqueous emulsion, dispersion or suspension, which is prefoamed by incorporating air in the aqueous liquid mixture , e.g. by blowing or mixing, with vigorous agitation in the presence or absence of a conventional blowing agent.
  • the resulting frothed or foamed, aerated composition is then coated to a thickness of from about 5 to about 100 mils on the preformed mat surface under ambient conditions using a knife blade, a roller or any other convenient method of application.
  • the foam coated mat is then dried at below its cure temperature to provide a foamed, self-supporting product having a reduced coating thickness of up to 90 mils which adheres to the mat surface.
  • the foamed coated mat is dried and cured simultaneously.
  • the resulting facer product of this invention is desirably flexible and possesses low permability to liquid chemicals used for insulation cores as well as superior dimensional stability and high tensile strength after curing.
  • This product comprising the mat having an adhered surface coating of a prefoamed latex/filler/surfactant, can be fed directly to insulation board manufacture, e.g. a constricted rise laminator, wherein the uncoated fiber surface of the mat contacts at least one exposed surface of a foamed or foamable thermosetting non-elastomeric core in the manufacture of an insulation board as described hereinaf er .
  • the foamed coating of the present facer can be formed in the absence or presence of a blowing agent to provide a composition of reduced density, which density can be reduced from above about 2 g/cc to as little as 0.15 g/cc.
  • the consistency of the foam is such that the coating mixture does not penetrate through the mat and ideally simulates the consistency of shaving cream.
  • the amount of air incorporated into the foamable mixture prior to coating is between about 5% and about 80% by volume for optimal consistency and the resulting foamed mixture has bubble openings sufficiently small so as to inhibit liquid bleed through the mat.
  • Applying a film or laminating a layer of impervious resin or polymer over the foamed surface to provide a trilayered facer member can provide a totally liquid impervious surface on the facer, in special cases where such is desired.
  • a top seal coat of a non-foamed latex is suitable for this purpose.
  • a thermoplastic such as polyethylene powder or unexpanded polystyrene beads can be used as a filler which melts at the drying/curing temperatures to close substantially all pores of the pervious coating.
  • Expandable excipients and additives such as cellulose can also be used for this purpose; although the use of a seal coat is neither needed nor recommended.
  • the facer of the invention having a foamed cellular coating contains latent exothermic energy and has a higher potential heat capacity upon entering the laminator; thus lowering the lamination cure time and prolonging the generation of heat by acting as an insulator during curing in the post cure stack.
  • This advantage eliminates the need for heat retaining members at the top and bottom of the stack and significantly reduces the prior problem of the board' s susceptibility to cold temperature delamination .
  • the foamed coating on the facer is dried and/or cured, the bonding strength between the uncoated fibers and the core material in the resulting product is enhanced due to reduced penetration of the coating mixture into the mat by reason of its prefoamed state.
  • the core material is either poured onto the uncoated fibrous surface of the facer or laminated thereto with adhesive or bonding agent .
  • Any pressure which may be applied during lamination in the insulation board manufacture is less than that required to cause a 50% reduction in the thickness of the foamed facer coating and insufficient to result in damage or crushing of the mat fibers in the finished insulation board product.
  • the weight of the present facer can vary from about 40 to about 300 g/sq. meter and the foamed facer sheet can have a thickness up to about 100 mils depending on the preference of the consumer .
  • laticies which can be crosslinked can be selected.
  • the present latex coating composition may additionally contain a minor amount, up to 15%, preferably less than about 3 wt.%, of a conventional thickening agent, for example an acrylic polymer thickener, e.g. (ACRYSOL ASE 95NP and/or 60NP) and the like.
  • a conventional thickening agent for example an acrylic polymer thickener, e.g. (ACRYSOL ASE 95NP and/or 60NP) and the like.
  • Other inert excipients such as a UV or thermal stabilizer, a conventional coloring agent, texturizing agent, reinforcing or crosslinking agent, (e.g. CYMEL 303 resin) and/or blowing agent may also be included in the coating mixture; although addition of these additives in a minor amount of less than 2 wt.% are preferred.
  • the insulation boards for which the present facer is particularly suited, comprise conventional thermosetting or thermoplastic foam cores, such as foamed polyurethane or polyurethane modified polyisocyanurate or phenol-formaldehyde cores disposed between a pair of facer members which are laminated to the core surf ces .
  • foamed polyurethane or polyurethane modified polyisocyanurate or phenol-formaldehyde cores disposed between a pair of facer members which are laminated to the core surf ces .
  • Other non-elastomeric foamable chemicals such as polyvinyl chloride, polystyrene, polyethylene, polypropylene, and others conventionally employed as core material can also be employed as the insulation board core of this invention.
  • Rigid foamed cores of this type are described for example in U. S. Patent 4,351,873, incorporated herein by reference .
  • the present facers are also suitable for sheathing a siding underlayment generally of a thickness up to about 1 inch and composed of a non-elastic core material of a chemical or chemical mixture similar to that of the insulation core.
  • a siding underlayment generally of a thickness up to about 1 inch and composed of a non-elastic core material of a chemical or chemical mixture similar to that of the insulation core.
  • instant facer eliminates the need for expensive foil facings which hold and reflect heat and often cause warping and deterioration of wood overlayment. Also, foil and similar facings are easily punctured which gives rise to moisture attack.
  • a roll of the present foamed facer sheet product is passed, with its uncoated fiber surface opposite the core surface, to a laminating zone .
  • the board core foam precursor chemical or mixture of chemicals can be poured onto the non-coated fiber surface of the facer sheet or the core of the insulation board can be prefoamed to a self-sustaining consistency.
  • a first facer of this invention with its uncoated surface abutting the core, is placed below the core .
  • the fiber surface of a second facer is positioned and spaced above the core to allow for core expansion, e.g. in a constricted rise laminator, where the assembly undergoes an exothermic reaction and curing is initiated.
  • one of the first and second facers can be of the same or of a different composition than that of this invention; although it is preferred that both of these facers be those of the invention described herein. More specifically, one of the facer sheets may be selected from those conventionally employed, such as for example a cellulose or cellulose-glass hybrid felt sheet, perlite, aluminum foil, multilaminated sheets of foil and Kraft, uncoated or coated fiber glass mats; although the second facer sheet of the present invention enhances the advantages described herein.
  • the core foam As the core foam is spread on the fibrous surface of the first facer sheet entering the laminator, it undergoes an exothermic reaction which can attain a temperature up to about 200°F.
  • the core foam rises to contact the undersurface of the second facer and hardens thereon; thus providing a rigid insulating foam core interposed or sandwiched between two acer sheets .
  • the resulting product can then be cut into boards of desired size and shape .
  • the heat of the exothermic reaction involving polymerization and/or crosslinking is autogenerated in both the laminator and in the subsequent stacking of insulation boards to insure complete curing of the core and surface coating of the facer. Curing temperatures during stacking can rise up to about 325°F over a period of up to 4 days.
  • the top and bottom positioning of the facer sheets can be reversed so that the facer of this invention is fed and spaced above a conventional facer in a manner such that its non-coated fibrous surface faces the foamable insulating core chemical being contacted on its under surface with another facer shee .
  • the later procedure is practiced where one facer is a rigid sheet, as in a perlite or particle board facer as opposed to the flexible facer of this invention which can be fed to the laminator as a continuous roll .
  • the foamable insulating core chemical is surfaced on the rigid facer member and rises to engage the fibrous uncoated surface of the present facer .
  • the latex of the present facer surface layer which, due to its comparatively thick latex foam, and low fiber to coating latex ratio, more efficiently retains heat between the layers of the roll .
  • lamination of the core can be completed at a faster rate and stacking accomplished without damage to the laminate .
  • this retention of heat during curing improves core bonding and significantly reduces subsequent "cold temperature delamination" in the product, which is caused by failure of the top layer of insulation to completely cure due to cooler temperature exposure during stacking after leaving the laminator.
  • the insulation boards incorporating the present facers are useful in commercial roof insulation, residential or commercial wall sheathing etc.
  • the present insulation board has a core thickness which may vary widely, for example between about 0.5 and about 4 inches or more .

  • the facers and the insulation board products of this invention exhibit significantly higher tensile strength than those containing 60-90 wt.% fibers.
  • the present facers also possess resistance to cracking at low temperatures and exceptionally superior dimensional stability and flame retardance . Because of their superior strength and flexibility, the present facer can find broader application, such as non-foil, non-glare sheathings , as shingle underlayment, separation or barrier sheets and the like .
