DETAILED DESCRIPTION
[0020] Disclosed herein is building materials containing latent heat storage materials and methods of making the same. Examples of building materials include, but are not limited to, gypsum board, wafer board, particle board, oriented strand board (OSB), plywood, fiberboard, medium density fiberboard (MDF), oriented strand lumber (OSL) parallel strand lumber (PSL), laminated veneer lumber (LVL), laminated strand lumber (LSL), cement board, wood, wood veneer, wood-plastic composites, plastic, plastic-cement composites, and combinations comprising at least one of the foregoing.
[0021] In one embodiment, the building material comprises a paneled article having a first side and a second side; a layer of encapsulated latent heat storage material disposed on the first side; and a coating disposed over the layer of encapsulated latent heat storage material. For ease in discussion, reference is hereinafter made to a gypsum board as an example of a building material for ease in discussion with the understanding that this disclosure can be adopted by a person of skill in the art to other building materials.
[0022] The term "latent heat storage" material is defined herein as a substance that has a phase transition temperature within a temperature range within which heat-transfer is intended. These materials are sometimes also referred to as phase change materials (PCMs). The PCMs disclosed herein have a solid/liquid phase transition in the temperature range from -20 C (degrees Celsius) to 120 C.
[0023] Without wanting be bound by theory, it is believed that the location of the PCM in gypsum board can improve efficiency of heat transfer, thereby allowing less PCM material to be employed compared to, for example, homogenously distributing PCM in a gypsum core. More particularly, it is believed that the closer the PCM is to the surface of the gypsum board the more efficient the heat transfer will be. Embodiments are hereinafter described that have a stratified structure having a layer comprising a PCM.
[0024] Referring now to Fig. 1, an exemplary embodiment of a gypsum board is shown, The gypsum board 10 comprises a board core 12 faced with a first facing material 14 and a second facing material 16. The facing material 14 and,16 may be the same or different. For example, both facing material 14 and 16 may comprise glass fibers, both may comprise paper, or one may comprise paper and the other glass fibers. Other materials are envisioned for the facing materials 14 and 16 and are not a critical aspect of the invention. In one embodiment, both facing materials 14 and 16 comprise glass fibers nominally about 10 to 16 microns in diameter and about one-quarter (1/4) to about one (1) inch in length, the first fiber mat in the absence of coating has a basis weight of I to 3 pounds per 100 square feet.
[0025] The board core 12 is basically of the type used in gypsum structural products commonly known as gypsum wallboard, dry wall, gypsum board, gypsum lath and gypsum sheathing. The core of such a product is formed by mixing water with powdered anhydrous calcium sulfate or calcium sulfate hemi-hydrate (CaS04.'/2H20), also known as calcined gypsum, to form an aqueous gypsum slurry, and thereafter allowing the slurry mixture to hydrate or set into calcium sulfate dihydrate (CaSO4.2H20), a relatively hard material. The invention is not limited to any particular content of gypsum in the core.
[0026] A coating layer 18 is disposed on the first facing material 14. An optional coating layer 22 can be disposed on facing material 16. The coating material employed in coating layer 18 and 20 can be the same or different. In one embodiment, the coating layer 18 comprises a plurality of capsules 20 containing PCM. The capsules containing PCM are disposed within the coating such that substantially no capsules containing PCM is exposed to an outer surface of the coating layer 18. The term "substantially" free or substantially none is being used throughout this disclosure to mean less than 10% by weight, based on a total weight (as defined by context, e.g,, weight of coating), specifically less than 5% by weight.
[0027] The coating material used in coating layer 18 is selected to be compatible with the encapsulation material of PCM capsules 20 and the desired application. For example, if the coating layer 18 is disposed on the facing material 14 to form a pre-coated facing material, the porosity of the coating is controlled to allow water to evaporate thru the coating layer 18. In "post" coating operations, porosity of the coating is less important. The term "post coating" is being used herein to refer to a coating operation after the gypsum board has been formed and dried in a drier. One potential advantage of post coating is less energy can be consumed compared to drying a gypsum board containing PCM, since the PCM absorbs heat energy.
[0028] Embodiments are envisioned where the coating layer comprises an organic binder, an inorganic binder or combinations of organic and inorganic binders.
The choice of binder will vary depending on application and method employed in making the gypsum board 10.
[0029] In one embodiment, the coating material used in the coating layer 18 compries an organic binder. Examples of organic binders include, but are not limited to, styrene-butadiene-rubber (SBR), styrene-butadiene-styrene (SBS), ethylene-vinyl-chloride (EVC1), poly-vinylidene-chloride (PVdC), modified poly-vinyl-chloride (PVC), poly-vinyl-alcohol (PVOH), ethylene-vinyl-acetate (EVA), and poly-vinyl-acetate (PVA). Asphalt is not generally used as a binder in making a coated mat useful in this invention.
[0030] The coating layer 18 can optionally comprise a filler material.
Examples of filler materials include, but are not limited to, ground limestone (calcium carbonate), sand, mica, talc, gypsum (calcium sulfate dihydrate), aluminum trihydrate (ATH), antimony oxide, or a combination of any two or more of these substances.
[0031] The PCM capsules 20 can be microcapsules, microcapsules, or a combination of the foregoing. The capsules comprise a capsule core of latent heat storage material and capsule wall of polymeric material, wherein about 90% or greater of the total weight of the capsule is the latent heat storage material, The term "microcapsule" is being used throughout this disclosure refers to capsules having a mean diameter of 1 to 100 um (micrometers). The term "macro capsule" is being used throughout this disclosure referred to any capsules having a mean diameter greater than 100 Jun. The choice of capsule size will be variable dependent on desired application (e.g. fire rating).
[0032] Example of PCM materials and methods of making are discussed in U.S. Patent 7,166,355 and include, but are not limited to: 1) aliphatic hydrocarbon compounds such as saturated or unsaturated C10-C40-hydrocarbons which are branched or specifically linear, e.g. n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nonadecane, n-eicosane, n-heneicosane, n-docosane, n-tricosane, n-tetracosane, n-pentacosane, n-hexacosane, n-heptacosane, n-octacosane, and cyclic hydrocarbons, e.g. cyclohexane, cyclooctane, cyclodecane; 2) aromatic hydrocarbon compounds such as benzene, naphthalene, biphenyl, o- or n-terphenyl, C1-C40-alkyl-substituted aromatic hydrocarbons such as dodecylbenzene, tetradecylbenzene, hexadecylbenzene, hexylnaphthalene or decylnaphthalene; 3) saturated or unsaturated C6-C30-fatty acids such as lauric, stearic, oleic or behenic acid, specifically eutectic mixtures of decanoic acid with, for example, myristic, palmitic or lauric acid; 4) fatty alcohols such as lauryl, stearyl, oleyl, myristyl and cetyl alcohols, mixtures such as coconut fatty alcohol and the oxo alcohols obtained by hydroformylation of a-olefins and further reactions; C6-C30-fatty amines such as decylamine, dodecylamine, tetradecylamine or hexadecylamine; 5) esters such as C10-alkyl esters of fatty acids, e.g. propyl palmitate, methyl stearate or methyl palmitate, and specifically their eutectic mixtures or methyl cinnamate; 6) natural and synthetic waxes such as montanie acid waxes, montanic ester waxes, carnauba wax, polyethylene wax, oxidized waxes, polyvinyl ether wax, ethylene-vinyl acetate wax or hard waxes from Fischer-Tropsch processes; 7) halogenated hydrocarbons such as chloroparaffin, brornooctadecane, bromopentadecane, bromononadecane, bromoeicosane, bromodocosane.

[0032] Example of PCM materials and methods of making are discussed in U.S. Patent 7,166,355 and include, but are not limited to: 1) aliphatic hydrocarbon compounds such as saturated or unsaturated C10-C40-hydrocarbons which are branched or specifically linear, e.g. n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nonadecane, n-eicosane, n-heneicosane, n-docosane, n-tricosane, n-tetracosane, n-pentacosane, n-hexacosane, n-heptacosane, n-octacosane, and cyclic hydrocarbons, e.g. cyclohexane, cyclooctane, cyclodecane; 2) aromatic hydrocarbon compounds such as benzene, naphthalene, biphenyl, o- or n-terphenyl, C1-C40-alkyl-substituted aromatic hydrocarbons such as dodecylbenzene, tetradecylbenzene, hexadecylbenzene, hexylnaphthalene or decylnaphthalene; 3) saturated or unsaturated C6-C30-fatty acids such as lauric, stearic, oleic or behenic acid, specifically eutectic mixtures of decanoic acid with, for example, myristic, palmitic or lauric acid; 4) fatty alcohols such as lauryl, stearyl, oleyl, myristyl and cetyl alcohols, mixtures such as coconut fatty alcohol and the oxo alcohols obtained by hydroformylation of a-olefins and further reactions; C6-C30-fatty amines such as decylamine, dodecylamine, tetradecylamine or hexadecylamine; 5) esters such as C10-alkyl esters of fatty acids, e.g. propyl palmitate, methyl stearate or methyl palmitate, and specifically their eutectic mixtures or methyl cinnamate; 6) natural and synthetic waxes such as montanie acid waxes, montanic ester waxes, carnauba wax, polyethylene wax, oxidized waxes, polyvinyl ether wax, ethylene-vinyl acetate wax or hard waxes from Fischer-Tropsch processes; 7) halogenated hydrocarbons such as chloroparaffin, brornooctadecane, bromopentadecane, bromononadecane, bromoeicosane, bromodocosane. An example of a commercially available microcapsule PCM is MicronaiThi from BASF.
[0033] Referring now to Fig. 2, an exemplary embodiment of a gypsum board 100 is shown. This embodiment illustrates another potential location option to allow the PCM to be proximate to a surface of the gypsum board. The gypsum board 100 comprises a board core 112 faced with a first facing materia1114 and a second facing material 116. A coating layer 118 is disposed on the first facing material 114. An optional coating layer 122 can be disposed on facing material 116. In this example, a plurality of capsules 120 containing PCM are located in a layer within the board core 112 itself. It is to be understood by a person of skill in the art that the choice of materials used in this embodiment can be the same as those mentioned above in relation to the embodiment shown in Fig. 1.
[0034] Referring now to Fig. 4, one convenient way to dispose the capsules in a layer within the board core is to meter them from a holding tank 401 into a separate stream of gypsum slurry at throughoutlet 417 to provide a relatively thin layer of aqueous calcined gypsum slurry 418 on the non-coated surface of sheet 416. The thin layer of gypsum slurry 418 is somewhat more dense than the aqueous slurry of gypsum that is used to form the main portion of the core of the gypsum board (main core slurry discharged through outlet 419 from mixer 420 to form gypsum slurry layer 423). The slurry used to form the thin layer 18 is about 18-20% more dense than the density of the slurry 23 used to form the main portion of the core. A portion of this denser slurry also is often used to form hard edges of the gypsum board as well. The continuous sandwich of slurry and applied facing materials (414 and 416) is carried down conveyors 422.
[0035] Other embodiments are envisioned where the PCM is applied downstream or upstream of the mixer such that the PCM is in proximity of the facing material. The challenge in these approaches is to provide a sufficient amount of gypsum slurry contact with the facing material. Vibrating tables may also be employed as a means of having the PCMs settle near the surface of the gypsum board.
Additionally, the relatively more heavy macrocapsules compared to mierocapsules can advantageously settle near the surface of gypsum board.

Additionally, the relatively more heavy macrocapsules compared to mierocapsules can advantageously settle near the surface of gypsum board.
[0036] Referring now to Fig. 3, an exemplary embodiment of a gypsum board 200 is shown. This embodiment illustrates yet another potential location option to allow the PCM to be proximate to a surface of the gypsum board. The gypsum board 200 comprises a board core 212 faced with a first facing material 214 and a second facing material 216. A coating layer 218 is disposed on the first facing material 214.
However, in comparison to the embodiment illustrated in Fig. 1, the plurality of capsules 220 containing PCM is present in a greater concentration near the surface of the facing material 214. The challenge in this approach is to provide a sufficient amount of coating contact with the facing material to create a bond, [0037] While Figs. 1-3 are discussed as separate embodiments for the purposes of illustration, it is to be understood that various combinations of these embodiments is envisioned. Embodiments are also envisioned where the facing material is eliminated. Further these boards can be laminated to other structures to provide multiple functions (e.g., sound abatement).
[0038] Advantageously, embodiments illustrated herein are helpful in creating a building material that when used in place of a similar building product without PCM
provides greater energy efficiency in a build, which thereby can reduce carbon dioxide foot print of a building.
[0039] Ranges disclosed herein are inclusive and combinable (e.g., ranges of "up to about 25 wt%, or, more specifically, about 5 wt% to about 20 wt%", is inclusive of the endpoints and all intermediate values of the ranges of "about 5 wt% to about 25 wt%," etc.). "Combination" is inclusive of blends, mixtures, alloys, reaction products, and the like. Furthermore, the terms "first," "second," and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and the terms "a" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item.
