Claims. (Cl. 1542) provision of a novel method of deriving a panel structure having an attractive decorative finish which will not be marred under the foregoing stated conditions.
A further object of the present invention is the provision of laminated panel structures which are economical in construction, while being adaptable to many uses in the furniture industry and which are durable undervarious environments of use.
A still further object of the present invention is the provision of a novel method of firmly affixing thin sheet-metal to a base material to form a panel and which metal, when ultimately decorated, serves to protect both the material comprising a decorative finish on the panel and the material comprising the base thereof.
Other objects of the invention will become apparent from the following description, setting forth a preferred method of constructing the panel and a preferred form of panel structure. The essential features of the invention are set forth inthe claims appended hereto.
In the drawing, Fig. 1 is a diagrammatical cross-section of the various materials utilized in carrying out my invention, the materials being shown in laminated relationsh'p and exaggerated in form, and Fig. 2 is a perspective view of a furniture panel, preferably having a base formed of a fibrous material, such as wood.
Broadly, I incorporate in a panel structure a thin metal sheet, upon which the decorative finish is carried, and which metal sheet serves as a heat conductor to protect the coating mate- I have determined that a definite relation exists between the coemcient of conductivity of a lamination of sheet-metal used upon the top of a scorchable fibrous base, such as wood, and the baking temperatures of the coating materials comprising the finish applied to the sheet-metal as a decorative covering. I first determine the baking temperature of the coating materials and the heatmarring temperature. By thus predetermining the thickness of the metalsheet, the materials comprising the finish coatings upon the top of the metal sheet and the fibrous material comprising the basecan be protected against marring and charring, respectively, when burning matches,
v cigarettes or hot utensils are carelessly placed conductiv capacity of the sheet-metal by predetermining its thickness so that the sheet is of su-fiicient cross-section to prevent any localized part of the metal from rising to a finish thereon.
As an example, when a panel is built up with a wood base, and a previously decorated sheetmetal lamination is secured to the top thereof, by the use of a suitable cement or glue, and the decorative coating applied to this metal has a baking temperature of about 350 degrees Fahrenheit, the thickness of th metal sheet can be varied, dependent upon the kind of metal which forms the sheet. When a sheet of metal, having a high conductivity factor. is used, the thickness of the metal sheet can be considerably less than when sheet-metal having a low conductivity factor is used. Economically practical sheet-metals for my present purposes are aluminum or sheet steel, although commercial circumstances might be such that thin sheet copper could be used.
The heat conductivity factor of sheet aluminum at about 78 degrees centigrade is about .495, while that of steel, at the same temperature, is about .107. These factors are determined by establishing the quantities of calories, which will be transmitted per second through a plate of the metal one centimeter thick, across an area of one square centimeter when the temperature difference is one degree centi rade. Hence, aluminum at about '78 degrees centigiade is about four and one-half times greater in heat conductivity than sheet steel. Thus, when sheet aluminum is used, the thickness thereof could be four times less than thethickness of sheet steel to disburse or conduct away from a localized heated zone on the panel surface, the heat tending to accumulate, although I prefer to maintain a ratio between the thickness of aluminum and steel of three to one.
I have determined that sheet steel, having a thickness of .016 of an inch, has been found to have a sufiiciently high heat dispersion or heat conductivity capacity to conduct heat away from a heated localized zone upon the panel finish, thus preventing charring of the wood base to which the sheet metal is afiixed, while also preventing any marring or discoloration of the materials comprising the finish upon the sheet-metal surface. An aluminum sheet .005 of an inchhas been found to perform the same function.
a suitable adhesive which will withstand localized heat while the same is being dispersed, may comprise latex and casein mixed with a suitable solvent, and the top and ground coatings for decorating the metal sheet having suflicient- 1y high baking points 'or temperatures, may have modified alkyd resin bases.
The order of assembly of the laminations forming the panel structure, as well as the application of the materials thereto, is important, for I have encountered considerable diificulty in devising a practical method of firmly affixing the metal sheet to the base material throughout the undersurface of the metal sheet, after the metal sheet had been decorated. When a glue or adhesive which would adhere .to the fibrous base was used, such materials fail to adhere properly to the underside of the sheet metal, and when an adhesive, which would adhere properly to thesheet metal was used, such materials fail to adhere to the fibrous base. This difilculty was overcome by applying a coating of material to the underside of the metal sheet, which could be baked on and an adhesive, which would adhere firmly to this baked coating and to the base material, was then used.
In the present method, the underside of the sheet of metal I, after having been cleaned properly, has applied thereto a varnish coating 2 of such predetermined baking temperature that when the decorating coatings to the top side and baked, the underside coating 2 will not deteriorate and will firmly adhere to the surface of the metal sheet. In other words, the material used in making the coatings 2, 3 and 4 are such that the coatings may have substantially common baking temperatures, although the sequence of coating applications to the top and bottom surfaces of the sheet metal may be reversed by the selection of proper materials which, when baked at a required temperature,'
will not cause deterioration of the previously applied coating. Also, if desired, by effecting a preliminary drying of the first applied coating, be the same eitherthe decorative coating or the sheet metal adhesive coating, the baking of both coatings may be obtained in one bake.
The coating of adhesive 5 can be applied to the fibrous base material 6, or, if desired, may be applied to the metal sheet over the varnish coating 2, whereupon the finished metal sheet I may be applied to the base 6 with sufilcient pressure, by the use of. any convenient means,- to bring about intimate contact throughout the top surface of the base material 6 and the underside of the treated sheet-metal I. By finishing the sheet of metal I and treating the undersurface thereof in the manner hereinbefore described, the proper drying and setting of the adhesive or glue at low temperatures, even at a comparatively cold temperature, can be effected without causing warping of the base material 6.
I am aware that attempts have been made heretofore to produce scorch-proof panels by incorporating a metallic sheet in a plurality of phenol formaldehyde treated layers of wood veneer and paper which were first assembled and cured while under heat and pressure to form a composite slab. However, by my present panel structure and method of forming the same, considerable economy in the manufacture of the panel is obtained and there is no limitation upon the extent of decorative variation made available to the manufacturer nor is there any limitation 3 and 4 are applied in the selectionof the fibrous materials forming ll fact, any photographically 'reproducable design,
or simulation may be obtained by placing a transfer of the same upon the ground coat surface as indicated by the dot and dash lamination or layer I in Fig.-1.
The base material may comprise solid wood or plywood, cork, plaster board, any of the commercially known fibre boards or a built-up base of wooden members may form the base.
