Definitions
- the present invention is directed to fire and sag resistant panel, and, more particularly, to an enhanced fire rated, sag resistant acoustical ceiling panel having an enhanced fire rated natural fiber mat incorporated therein.
- Natural fibers such as hemp, kenaf, jute, sisal and flax, are gaining interest as a component in a variety of manufactured products, including products for the interior building environment, as natural fibers are a renewable resource and do not emit potentially hazardous materials into the environment. Though renewable and environmentally friendly, natural fibers, and the binder material which holds the fibers together, are highly flammable.
- Articles intended for use specifically in a construction which is utilized as a conduit for return air must achieve an exceptional Class A fire resistance rating: namely a flame spread index value of 25 or less and a smoke generation index value of 50 or less, as measured by ASTM E 84.
- an exceptional Class A fire resistance rating namely a flame spread index value of 25 or less and a smoke generation index value of 50 or less, as measured by ASTM E 84.
- the invention is a ceiling panel structure which includes a fire retardant mat.
- the fire retardant mat includes a fire retardant fiber component and a binder material which binds the fibers.
- the fire retardant fiber component includes natural fibers treated with a fire retardant.
- the fire retardant mat has flame spread index of 25 or less and a smoke generation index of 50 or less, as measured by ASTM E 84 that is uniform throughout the mat.
- the ceiling panel structure also includes a scrim attached to the bottom surface of the fire retardant mat as well as a coating on the exposed surface of the scrim opposite the fire retardant mat.
- the ceiling panel structure also achieves a flame spread index value of 25 or less and a smoke generation index value of 50 or less, as measured by ASTM E 84 that is uniform throughout the structure.
- Figure 1 is a side view of a fire retardant mat according to an embodiment of the invention.
- Figure 2 is a side view of a ceiling panel structure incorporating the fire retardant mat of Figure 1.
- DETAILED DESCRIPTION OF THE EMBODIMENTfS [0008]
- Figure 1 shows a fire retardant mat 1 according to an embodiment of the invention.
- a fiber component comprising natural fibers treated with the fire retardant is mixed with a binder to form a blend.
- the fiber component may be mixed with the binder, for example, by carding and co-mingling the fiber component with the binder in an air stream, which separates the natural fibers from one another and intimately blends the natural fibers with the binder.
- the blend, or furnish is then deposited onto a foraminous wire and is compressed to a desired final thickness. Heat is then applied through the fiber web to either melt a thermoplastic binder or cure a thermosetting binder. Alternatively, the blend may be conveyed through an oven that blows heat through the mixture while the mixture is simultaneously being compressed with one or more wire screens.
- the fiber component includes natural fibers treated with a fire retardant.
- Bast fibers such as kenaf, hemp, flax, ramie, or jute are examples of natural fibers.
- the natural fiber ingredient may comprise a single type of fiber or a combination thereof. Additionally, a portion or all of the natural fibers may be recycled fibers. Kenaf, jute, hemp, or combinations thereof are preferred where strength and/or rigidity is sought as these particular fibers are inherently less flexible than other natural fibers.
- the fire retardant may be in the form of a powder or liquid and can be, for example, ammonium phosphates, sodium pentaborates, ammonium sulfates, boric acids and mixtures thereof.
- the fiber component comprises from about 70-99% by dry weight of the mat, and more preferably from about 70 to about 83% by dry weight of the mat.
- the ratio of the natural fiber to fire retardant in the fiber component is in the range from about 4:1 to about 11.5: 1 and more preferably about 5: 1.
- the amount of binder in the mat in the mat is in the range from about 1 to about 30% by dry weight of the fiber mat.
- the binder can be either thermoplastic (including bio-based polymers) or thermosetting.
- the material range is more preferably from about 11 to about 30%; most preferably about 13 to about 21%.
- the material range is more preferably from about 1 to about 15%; most preferably about 2 to about 8%.
- thermoplastic binder fiber is the bi-component sheath-core configuration having a first thermoplastic material coated or encased within a second thermoplastic material having a lower softening temperature.
- the first thermoplastic material may be, for example, polyethylene terephthalate glycol (PETG)
- the second thermoplastic material may be, for example, polyethylene terephthalate (PET).
- PETG polyethylene terephthalate glycol
- jute fiber was treated either with a system of ammonium phosphate and borate or with di-ammonium sulfate.
- the preferred mat density for use in a ceiling tile structure is in the range from about 4 to about 8 lb/ft 3 and, more preferably from about 5 to about 6.5 lb/ft ; most preferably about 5.51b/ft .
- the preferred thickness of the mat for use in a ceiling tile structure is in the range from about 0.25 to about 2 inches, more preferably about 0. 0.375 to about 1.5 inches and most preferably from about 0.4 to about 0.7 inches.
- a facing scrim 3 and a scrim coating 6 composite was then adhered to sample mats 4-8 of Table 2.
- the scrim applied to sample mats 4-8 was a fiberglass scrim available from Owens Corning, item number A80PKR-YK1 1 1, however, the scrim 3 may be any suitable scrim that is resistant to flame spread and preferably has a Class A fire rating of 25/50, examples of which are fiberglass or flame retardant blends of fiberglass, cellulose and polyester.
- the fiberglass scrim is bound with a flame retarded polymeric binder.
- the scrim 3 can be attached to a surface of the fire retardant mat 1 using any suitable attachment method.
- the fiberglass scrim is affixed to the mat with flame- retarded vinyl-acetate glue 5.
- the air flow resistance of the A80PKR-YK11 1 scrim is 40 MKS Rayls.
- the scrim was then painted with DURABRITE paint available from Armstrong World Industries.
- the paint was applied at an application level of 29 g/ft2.
- What is key for achieving the desired acoustic performance in the fully constructed ceiling panel is that the combination of the scrim, the glue application and the paint application must have an air-flow permeability that allows sound to enter and be absorbed in the structure.
- a composite air flow resistance of about 400 to about 600 MKS Rayls has been found to achieve an noise reduction coefficient (NRC) greater than 0.80.
- NRC noise reduction coefficient
- the scrim weight In order to achieve the desired air flow resistance, and thus, the desired NRC, the scrim weight must be in the range from about 4.5 to about 10.5 g/ft2 and the glue application rate must be in the range from about 3 to about 10 g/ft2 (dry weight). The paint application rate must be in the range from about 10 to about 50 g/ft2 (dry weight).
- Table 3 illustrates examples of fully constructed two feet by two feet panels comprising the fire retardant mat samples shown in Table 2.
- the completed structural panels utilizing sample mates 4-8 were indeed found to obtain the desired fire resistance, sag and acoustical properties. Specifically, a completed structural panel achieved a noise reduction coefficient (NRC) of at least 0.85.
- the noise reduction coefficient (NRC) is a useful indicator of the acoustical properties of a given material.
- the Noise Reduction Coefficient (NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface. It is well known in the art that NRC is the average of four sound absorption coefficients of the particular surface at frequencies of 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz.
- the desired sag performance was also achieved; namely a statistical value more positive than negative 0.150 inches.
- To measure the sag performance several 2x2 inch panels were suspended horizontally from a perimeter support frame and deflection was measured over the course of four 24-hour cycles in which relative humidity was varied: namely 8 hours at 90% relative humidity and then 6 hours at 35% relative humidity. The negative most deflection from horizontal was recorded for each panel formulation.
- an average negative value minus 2 standard deviations that is more negative than negative 0.150 inches represents a threshold performance value for a 2x2 panel at which the sag in the middle of the panel becomes apparent and begins to show an unsightly pillowed appearance in a horizontal installation.
