Description
WO 2007/016746 PCT/AU2006/001141 1 A NON-STRUCTURAL MULTI-PART PANEL Field of the Invention. The present invention relates to panels and in particular, to non structural panels used to line elements of a building that assist with thermal and/or 5 soundproofing the structure. Background Art. An excellent summary of prior art panel members is given in United States Patent No. 6,698,149 and is repeated below verbatim: "A number of different types of laminated building materials are 10 known. Examples of some of the known laminated building materials are described in U.S. Pat. No. 4,078,348 to Rothman, U.S. Pat. No. 4,774,794 to Grieb, U.S. Pat. No. 4,973,506 to Bauer et al., U.S. Pat. No. 5,483,778 to Scrivener, and U.S. Pat. No. 6,235,367 to Holmes et al. Grieb, U.S. Pat. 4,774,794 discloses a laminated building block made 15 up of a foam core with a combined fiberglass and cementitious coating surrounding all sides of the core. The building blocks disclosed by Grieb are self-supporting and may be used in a load-bearing application, without a separate frame, to build structures such as homes and commercial buildings. Bauer et al., U.S. Pat. No. 4,973,506, discloses a decorative composite 20 plate for facing exterior building surfaces. The plate of Bauer et al. has a honeycomb core structure disposed between two cover layers. An outer cover layer carries a decorative panel, which may consist of stone, and the inner cover layer carries a protective plate. A number of different types of skirting material are known for use with 25 mobile homes. Examples of the known skirting materials include those disclosed in U.S. Pat. No. 3,753,323 to Nesbitt, U.S. Pat. No. 3,832,813 to Hindman, U.S. Pat. No. 4,680,904 to Stoecker, U.S. Pat. No. 4,843,793 to Ayers, and U.S. Pat. No. 6,205,720 to Wolfr-um. Although the known laminated building materials are useful for their 30 intended purposes, a need still exists in the art for building materials that are useful for decorative exterior placement on buildings. In particular, there is a need for a relatively lightweight and low cost decorative building material that is easy to install, WO 2007/016746 PCT/AU2006/001141 2 and that includes a durable material such as stone, tile or brick on an exterior surface thereof, for improving the appearance of buildings." It is therefore known to use polyurethane or similar as a component of a panel but such panels are normally structural rather than decorative. None of these are 5 specifically adapted to be used as a decorative panel with extreme lightness, thermal and soundproofing characteristics. It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or in any other country. 10 Summary of the Invention. The present invention is directed to a non-structural multi-part panel, which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice. In one form, the invention resides in a non-structural multi-part panel 15 including at least two layers, a first layer of foamed material and a second layer applied to at least one side of the first layer, the second layer of cellulosic material. The panel of the present invention finds particular application as a decorative panel in finishing of internal walls and ceilings in buildings. The lightweight nature of the panel of the present invention manufactured, as it will 20 typically be, of at least one layer of polyurethane material, will have a low thermal conductivity and also a low sound transmissivity providing a finishing panel with excellent thermal and sound proofing qualities. Typically, the at least one first layer of the panel is made from a rigid blown polyurethane foam of which Type-141B blown rigid foam is a preferred type. 25 This type of polyurethane foam generally has a density of between 55 and 150kg/m 3 . The polyurethane layer will generally have a thickness of 8mm up to 50mm, although it is to be appreciated that other thicknesses will also be manufactured where necessary. The density of the material used will depend on the type of material but typically, the density will be between 50 and 200kg/m 3 . 30 Generally the at least one polyurethane layer will be a central layer with a pair of second layers, one applied to each side of the central layer. The central layer WO 2007/016746 PCT/AU2006/001141 3 will generally be a sheet member with a pair of planar faces. Normally, the second layers will be applied to the planar faces. The second layers will typically both be a cellulosic layer, preferably of cellulose recycled paper. This may be accomplished using a machine specially 5 manufactured for this purpose or through direct lamination of the second layers to the first in any manner. Typically, each panel manufactured according to the invention may be manufactured with a tongue and groove or mortice and tennon provided at opposed lateral edges of the panel. This will preferably allow adjacent panels to be fitted 10 together when being installed. This is particularly useful when using the panels as a finishing sheet for walls or ceilings inside a building. The panel sheets of the invention may be manufactured of various sizes suited to buildings. Preferably, there will also be panel members manufactured in arcuate cross-sections and portions such as corner pieces to fit into internal or external 15 corners between walls and ceilings and the like. Preferably, due to the components used in manufacture and the manner in which they are used, the panel of the invention will be lightweight at approximately 2kg/m 2 at a thickness of between 12mm and 50mm. Other materials may be used to form the first central layer of the panel 20 or shaped portion. One particular example is polyisocyanurate boardstock foam which is an energy efficient and cost-effective insulation material. Type-141b is an ideal blowing agent for this application. Type-141b has a low vapor thermal conductivity that gives the polyurethane core blown with Type-141b good insulation value. Additionally, because Type-141b is generally a 25 liquid at atmospheric conditions, it allows the foam system to be easily processed and gives good flow properties to the foam. Good flow properties allow the material to fill the panels uniformly. However, Type-141b polyurethane foam has a major drawback in that it is a HCFC foam which has ozone-depleting properties and for this reason, 30 manufacture of HCFC 141b for use in foam blowing in the United States ceased on 1 January 2003 by order to the United States Environmental Protection Agency.
WO 2007/016746 PCT/AU2006/001141 4 The polyurethane foam normally used as the first layer in the panel of the invention typically plays an important part in meeting required thermal or energy conductivity requirements. For this reason, two materials which have been developed as replacements for HCFC 141b may also find application as the material for the first 5 layer of the panel of the invention, namely HFC-245fa and HFC-134a. HFC-245fa is the leading candidate material to replace the CFC 141b due to its zero ozone depletion potential, relatively low thermal conductivity, non flammability, low toxicity, good polyol compatibility, good masterbatch stability and compatibility with other materials. 10 HFC-134a is less preferred due to its more limited polyol compatibility and masterbatch solubility. The vapor-thermal conductivities of both HFC-245fa and HFC-134a are significantly higher than that of HCFC-141b. Intuitively, one would expect the insulating properties of foams blown with either HFC to be worse than the 15 corresponding properties of HCFC-141b blown foam. However, this is not the case with HFC-245fa blown foam. HFC-245fa foam can deliver insulation performance equivalent to the HCFC-141b blown foams. HFC-134a blown foam insulation has yet to show this equivalency. This is primarily due to the solubility characteristics of HFC-134a in 20 polyols. In order to maintain a reasonable density, foam formulations employing HFC-134a as the physical blowing agent require higher levels of the chemical blowing agent water. Water reacts with the isocyanate portion of the polyurethane formulation to generate carbon dioxide gas. Higher concentrations of carbon-dioxide gas, which 25 has a high vapor-thermal conductivity, result in a higher overall thermal conductivity for the resulting foam. Higher thermal conductivity translates to a less efficient insulation. Although the k-factor of the HFC-245fa foam is higher than the HCFC 141b foam at a 75oF mean sample temperature, the k-factor at a 35 0 F mean sample 30 temperature is significantly lower. Thus, an average insulating performance from HFC-245fa foam is generally equivalent to HCFC-141b foam. The HFC-134a blown foam's k-factor is higher than HCFC-141b foam at both temperatures.
WO 2007/016746 PCT/AU2006/001141 5 HFC-245fa blown-foam processes much like the HCFC-141b blown foam. Although HFC-245fa boils below room temperature, its good solubility characteristics in polyols allows processing that is similar to familiar liquid-blowing agents used in the past. The molded density of HFC-245fa foams is also comparable 5 to HCFC-141b foam. HFC-134a is a low-boiling-point blowing agent that produces a strong frothing effect when poured. While HFC-134a processes under conditions similar to currently used blowing agents, the froth (which is similar to shaving cream in appearance) does not flow as well as a liquid. Generally, this frothing effect leads to 10 higher moulded densities. Additionally, specialized equipment is needed to handle these blends because of the pressures involved in the use of HFC-134a. Further, the panel of the invention may include materials which increase the fire barrier properties of the panel of the invention, normally referred to as passive fire protection. In this context the term "passive" means the use of 15 materials that impart fire resistance. Passive fire protection systems are used extensively throughout the building and transportation industries and typically function by counteracting the movement of heat and/or smoke, by sealing holes, by prolonging stability of structures to which the system is applied and/or by creating thermal and/or physical barriers to the passage of fire, heat and smoke. 20 Typically, the passive fire protection of the present invention may be increased through the addition of fire resistant compositions to the materials used in the panel or as one or more separate layers to the panel itself. These compositions will preferably may form a physically strong coherent layer around the panel or a portion thereof. In particular, the presence of low levels of glass additive in fire 25 resistant compositions comprising a silicone polymer and mica, has been found to the mechanical strength of a ceramic formed on heating the composition. In this context a ceramic is an inorganic non-metallic solid material prepared by high temperature processing (e.g. above about 300 0 C.) For example, the central core layer may include a polymeric 30 composition with fire resistant properties. Preferably, the inner core of the panel or one or more layers of the panel may include a fire resistant composition comprising a silicone polymer; mica in WO 2007/016746 PCT/AU2006/001141 6 an amount of from 5% to 30% by weight based on the total weight of the composition; and a limited amount of glass additive sufficient to enable the formation of a self supporting ceramic material at temperatures above the decomposition temperature of the silicone polymer and below the fire rating temperature of the composition. 5 Alternatively, the glass additive in the composition may be present in an amount of from 0.3% to 8% by weight based on the total weight of the composition. For the purposes of this discussion regarding the fire resistant composition, the composition is discussed as a separate formulation to the formulation of the material of the core of the panel and appropriate adjustments to the relative 10 quantities of fire resistant composition and core material can be made by a person skilled in the art. Still further, the fire resistant composition may comprise a polymer component consisting of a silicone polymer; mica in an amount of from 5% to 30% by weight based on the total weight of the composition; and a glass additive in an amount 15 of from 0.3% to 8% by weight based on the total weight of the composition. The glass additive is particularly effective at extending the range of temperatures that result in formation of ceramics with good mechanical properties, thereby improving the performance of these compositions in passive fire protection applications. It also improves the mechanical strength of the resulting ceramic relative 20 to equivalent compositions without the glass additive. The type and mean particle size of the mica is typically selected based on the intended use of the composition, as described below. The glass additive may take a variety of forms such as powder, particles or fibres. Mixtures of one or more of these may be used. Preferably, the 25 composition comprises glass frits in the form of a powder or fine particles. Irrespective of form, the glass additive preferably has a softening point below 1050 0 C., for example below 800 0 C., and most preferably between 300 and 800 0 C. The softening point of a glass is defined by the temperature at which the viscosity of the glass equals 107.6 poise. 30 The glass additive may be one or a combination of silicate, borate, phosphate and/or lead based glass systems. Suitable glass additives are commercially available.
WO 2007/016746 PCT/AU2006/001141 7 Without wishing to be bound by theory, it is believed that compositions comprising a silicone polymer and from 5% to 30% weight of mica form a coherent ceramic product after exposure to elevated temperatures as a result of materials of lower melting point, which may be eutectic mixtures, forming at the interface of the 5 mica particles and particles of inorganic compounds formed from the decomposition of the silicone polymer (primarily silicon dioxide). Ordinarily, silicon dioxide and mica each have melting points well above 1050 0 C. However, the eutectic that forms at the interface melts at a lower temperature. This eutectic material is believed to act as a "bridge" between the silicon dioxide particles and the mica particles, thereby 10 solidifying the composition at the firing temperature. Upon cooling, a coherent ceramic product is formed and this has been found to be self supporting and able to withstand at least minor mechanical impacts or shocks. It is thought that the presence of the glass additive in the silicone polymer/mica compositions results in a stronger ceramic material being formed if the 15 composition of the invention is exposed to elevated temperature due to the glass softening or melting at a lower temperature than, and/or at a similar temperature to, that required for formation of the eutectic at the interface between the particles. This is thought to assist in "binding" the silicon dioxide and/or the mica particles together. In this way formation of a coherent ceramic product is improved and it is possible to 20 reduce the temperature required to form a comparatively strong ceramic material. If the levels of glass additive are in the range of from 0.3 wt % to 8 wt %, the additive does not adversely affect dimensional stability. In contrast, compositions having glass additives greater than 8% by weight experience sustained volume shrinkage when subjected to temperatures greater 25 than 1000 0 C. For fire protection applications, it is preferable that this shrinkage is less than 10% and more preferably less than 5%. Hence, the amount of glass added is adjusted to ensure that the composition or articles formed from the composition comply with the desired volume shrinkage limits for a given application at the fire rating temperature. 30 The composition may be required to form a self supporting porous ceramic (typically having a porosity of between 40 vol % to 70 vol %) when exposed to fire rating temperatures, and in that case, it is important that the composition does WO 2007/016746 PCT/AU2006/001141 8 not fuse. In the context of this discussion, "fuse" means that the liquid phase produced in the composition becomes a continuous phase, and/or that the mica particles largely lose their original morphology, and/or that the amount of liquid phase produced becomes sufficient to cause the ceramic to deform due to its own weight. The upper 5 limit for the addition of the glass components is preferably 8% by weight to avoid fusing of the composition occurring below the upper temperature of the exposure. Thus in the resulting ceramic the mica particles essentially retain their morphology, with only minor changes at the edges as a result of 'bridging' to silicon dioxide particles or 'binding' with glass particles. Hence, compositions in accordance with the 10 present invention yield a coherent ceramic product that has substantially the same shape and volume as the composition before it was exposed to elevated temperature. Such compositions can be described as retaining near net shape. The softening point of the glass typically has an impact on the properties of the ceramic formed at elevated temperatures. Glasses with relatively low 15 softening points provide enhanced mechanical strength at lower temperatures than glasses with relatively high softening points. The finer the particle size of the glass additive, the more effective it is at enhancing the mechanical strength of the resulting ceramic. A blend of glass additives having low and high softening points may be used to provide a composition which yields a ceramic on heating which develops good 20 mechanical properties after exposure to a large range of temperatures. The compositions of the present invention include as an essential component, a silicone polymer. The nature of the silicone polymer is not especially critical and: one skilled in the art will be aware as to the type of polymers which may be used. Useful silicone polymers are described in detail in the prior art including U.S. 25 Pat. No. 4,184,995, U.S. Pat. No. 4,269,753, U.S. Pat. No. 4,269,757 and U.S. Pat. No. 6,387,518. By way of more specific illustration, the silicone polymer may be an organopolysiloxane composed of units of formula: RrSi0 4 -r/2 in which 30 R may be identical or different and are unsubstituted or substituted hydrocarbon radicals, and r is 0, 1, 2 or 3 and has an average numerical value of from 1.9 to 2.1.
WO 2007/016746 PCT/AU2006/001141 9 Examples of hydrocarbon radicals R are alkyl radicals, such as the methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, neopentyl, tert-pentyl and hexyl radicals, such as n-hexyl, heptyl radicals, such as the n-heptyl, octyl radicals, such as the n-octyl, and isooctyl radicals, such as the 2,2,4 5 trimethylpentyl, nonyl radicals, such as the n-nonyl, decyl radicals, such as the n decyl, dodecyl radicals, such as the n-dodecyl, octadecyl radicals, such as the n octadecyl; cycloalkyl radicals, such as cyclopentyl, cyclohexyl and cycolheptyl and methyl cyclohexyl radicals; aryl radicals, such as the phenyl, biphenyl, napthyl and anthryl and phenanthryl; alkaryl radicals, such as o-, m- or p-tolyl radicals, xylyl and 10 ethylphenyl radicals; and aralkyl radicals, such as benzyl and .alpha.- and .beta.
phenylethyl. Examples of substituted hydrocarbon radicals R are halogenated alkyl radicals, such as 3-chloropropyl, the 3,3,3-trifluoropropyl and the perfluorohexylethyl and halogenated aryl, such as the p-chlorophenyl and the p-chlorobenzyl. 15 The radicals R are preferably hydrogen atoms or hydrocarbon radicals having from 1 to 8 carbon atoms, preferably methyl. Other examples of radicals R are vinyl, allyl, methallyl, 1-propenyl, 1-butenyl and 1-pentenyl, and 5-hexenyl, butadienyl, hexadienyl, cyclopentenyl, cyclopentadienyl, cyclohexenyl, ethynyl, propargyl and 1 propynyl. The radicals R are preferably alkenyl radicals having from 2 to 8 carbon 20 atoms, particularly vinyl. The end groups of the polymers may be trialkylsiloxy groups, for example trimethylsiloxy or dimethylvinylsiloxy groups, or derived groups where one or more of the alkyl groups has been replaced by hydroxy or alkoxy groups. The composition may include one or more than one crosslinkable 25 silicone polymer. The crosslinkable polymer can be any one which can be crosslinked by any one of the methods used for commercially available organopolysiloxane polymers including by free radical crosslinking with a peroxide through the formation of ethylenic bridges between chains, by addition reactions including reaction of silylhydride groups with allyl or vinyl groups attached to silicon, through 30 condensation reactions including the reactions of silanols to yield Si-O-Si crosslinks, or using other reactive groups. Depending on the type of silicone polymer used the composition will therefore further comprise a suitable crosslinking agent. Suitable WO 2007/016746 PCT/AU2006/001141 10 crosslinking agents are commercially available, for example there is a wide range of useful peroxides suitable for use in this application, such as dibenzoyl peroxide, bis (2,4-dichlorobenzoyl) peroxide, dicumyl peroxide or 2,5-bis(tert-butylporoxy)-2,5 dimethylhexene or also mixtures of these, and when appropriate they may be included 5 in the composition during the compounding process. The silicone polymers that can be used also include platinum catalysed liquid silicone polymers with unsaturated (typically vinyl) side chains that crosslink through the application of heat in an addition reaction. Such polymers are usually supplied as two components that are mixed together just prior to use. The viscosity of 10 these polymers ranges from pourable liquids through to stiff pastes. The silicone rubber compositions may also comprise a room temperature moisture-curable organopolysiloxane (RTV), for which an example is given in more detail in U.S. Pat. No. 5,023,295. In this case it comprises: (a) a diorganopolysiloxane having terminal hydroxyl groups, (b) crosslinking agent having an average of at least 3 hydrolysable 15 functional groups linked to a silicone atom per molecule, (c) a condensation catalyst, and (d) a platinum metal or compound. Other room temperature curing systems possessing alkyl silicate and metal salts of carboxylic acids as one part which is combined with the silanol end stopped diorganopolysiloxane and inert filler as the other part, as for example described in U.S. Pat. No. 4,184,995 will also be included. 20 Another type is where the silicone polymer is of high molecular weight and has vinyl side chains that require heat to crosslink, either through platinum catalysed addition reactions or peroxide initiated free radical reactions. These silicone polymers are widely available commercially from major silicone producers. The organopolysiloxane raw materials preferably also comprise 25 reinforcing fillers such as precipitated or pyrogenic silicas and/or non-reinforcing fillers. Further, the surface of these silica type fillers may be modified by straight or branched organopolysiloxanes, organo-chlorosilanes and/or hexamethyl disilazanes. The compositions include mica. The two most common classes of commercially available mica are muscovite and phlogopite. Muscovite mica is a 30 dioctahedral alkali aluminium silicate. Muscovite has a layered structure of aluminium silicate sheets weakly bonded together by layers of potassium ions. It has the following composition KA1 3 Si 3 0 10
(OH)
2 . Phogopite mica is a trioctahedral alkali WO 2007/016746 PCT/AU2006/001141 11 aluminium silicate. Phlogopite has a layered structure of magnesium aluminium silicate sheets weakly bonded together by layers of potassium ions. It has the following composition KMg 3 AISi 3 010o(OH) 2 . Both mica types are typically present in the form of thin plates or flakes having sharply defined edges. 5 Compositions containing phlogopite mica display greater mechanical strength when heated to about 1000'C. to form ceramics. However, they also show greater shrinkage than those containing muscovite mica. The use of muscovite mica is preferred in applications where greater dimensional stability is required. Commercially available grades of mica have a range of particle size 10 distributions. It has been found that the particle size of the mica has an important effect on the dimensional stability and mechanical properties of the ceramic product formed when a composition of the present invention is exposed to elevated temperature. Typically, the mica is selected so that it has a mean particle size of from 15 jim to 250 pm. Micas at the lower end of this range (e.g. less than 50 pm mean 15 particle size) result in ceramics that are mechanically stronger but display greater shrinkage that can result in cracking. Micas at the middle and upper end of the range are preferable for use in cable applications or other applications where shape retention is particularly important. If the mean particle size of the mica is too large or the amount of mica present is too high, the resultant composition tends to be difficult to 20 process and form into the desired configuration, for instance by extrusion. In addition, the mechanical properties of crosslinked silicone polymers containing coarser particle size grades of mica or high mica levels are poorer. The coarser mica particles tend to produce preferential alignments along their crystallographic basal planes when the compositions are extruded, or molded under compression, and this can result in low 25 tear strength. The mica may be surface treated with a silane coupling agent in order to enhance the mechanical properties before and/or after firing. Examples of silane coupling agents are vinyltrimethoxysilane, aromatic silane, aryl silane, epoxysilane, acrylsilane, polymeric silane and mercaptosilanes such as 30 mercaptopropyltrimethoxysilane. The silane coupling agent is preferably present in the range of from 0.05% to 2% by weight of the composition.
WO 2007/016746 PCT/AU2006/001141 12 The selection of the appropriate mica type, mean particle size and mica level will depend on the intended application, the required processing properties of the composition, the required mechanical properties of the crosslinked composition, and the required strength and extent of dimension retention required when converted to the 5 resulting ceramic. The properties which these compositions are desired to exhibit when exposed to the range of elevated temperatures commonly associated with a fire may be manipulated by suitable choice of the type and particle size of the mica which is used. In other words, the properties of these compositions may be tailored to the intended end use. 10 Preferably, the mica addition is from 5% to 30% by weight based on the total weight of the composition. Muscovite mica is the type generally preferred for those applications, but greater mechanical strength after firing at 1000 0 C. can be obtained using phlogopite mica. Other components may be incorporated into the compositions of the 15 present invention. The addition of zinc borate, magnesium hydroxide or alumina trihydrate, improves the flame retardant properties of the composition. Additionally, some may improve the strength of the ceramic. Other components include inorganic fibres or other fibre reinforcing materials, materials that reduce thermal conductivity (eg exfoliated vermiculite), chemical foaming agents (which serve to reduce density, 20 improve thermal characteristics and further enhance noise attenuation), extending non-reactive fillers, silica, and intumescing materials (to obtain a composition that expands upon exposure to fire or elevated temperature). Suitable intumescing materials include natural graphite, unexpanded vermiculite or unexpanded perlite. Other types of intumescing precursors may also be used. 25 The compositions may be prepared by blending and heating the various components. Heating is required for peroxide crosslinking of the silicone polymer to form a silicone elastomer. Any conventional compounding equipment may be used. If the composition has relatively low viscosity, it may be processed using dispersing equipment, for instance of the type used in the paint industry. Materials useful for 30 cable insulation applications are of higher viscosity (higher molecular weight) and may be processed using a two roll mill, internal mixers, twin-screw extruders and the like. Depending upon the type of crosslinking agent/catalyst added, the composition WO 2007/016746 PCT/AU2006/001141 13 can be cured by exposure to air at 200 0 C., in an autoclave with high pressure steam, using continuous vulcanisation equipment including a liquid salt bath and, conceivably, by exposure to any medium that will cause the peroxide to decompose, including microwaves, ultrasonic waves or the like. 5 Detailed Description of the Preferred Embodiment. A particularly preferred embodiment of the present invention is a non structural or decorative multi-part finishing panel which includes at least three layers. The three layers are an inner layer or central core of foamed material and an outer layer applied to both sides of the inner layer of cellulosic or paper material. 10 The panel of the present invention finds particular application as a decorative panel in finishing of internal walls and ceilings in buildings.
