Definitions
- My present invention relates to heat insulating board of the multi-layer type and more particularly to an improved heat insulation comprising a plurality of aluminum foils of hard and bright finish laminated in a board with a light Weight pervious spacing element which can be easily handled and used in complicated structures such as refrigerated railway cars and trucks, aeroplanes and the like.
- the principal object of my invention is to provide an insulating board of light weight suitable for the use in the low temperature field and especially in the refrigeration transportation field where moisture migration by diffusion from the warm side of the refrigerated structure often causes serious trouble.
- a further object of the invention is to provide a light weight insulation board of multi-layer aluminum foil in which direct metal conductivity is prevented by interspaced low conductive material.
- Another object of the invention is to provide a light weight heat insulation board-like structure in which heat radiation is effectively restricted by a plurality of double acting aluminum foils and in which convection fiow is restricted by a large number of layers and moisture migration by diffusion in a transversal direction is practically prevented by impervious metallic vapor barriers.
- FIG. l is a fragmentary perspective view of a heat insulation board constructed in accordance with my invention.
- Figure 2 is a fragmentary perspective view showing a modification of the heat insulation board
- Figure 3 is a fragmentary perspective view showing another modification of the heat insulating board.
- an insulating board made in accordance with the invention may comprise any number of foils and intervening layers of low conductive nited States Patent O 2 material depending upon the desired thickness of the board.
- the numerals 11 and 13 designate two bright and hard corrugated aluminum foils which, according to the invention, may vary from .0003 to .003 inch in thickness. These aluminum foils are separated by a similarly corrugated plastic film 12, the corrugations extending substantially between two parallel imaginary surfaces.
- the film may be of cellulose acetate, poly vinyl chloride or silicone plastic; This plastic film material like the aluminum foil is quite thin and may vary from .001 to .003 inch in thickness. 1
- the upper crests or ridges of the three corrugated foils as shown are respectively designated by the numerals 14, 16 and 18, and the lower ridges are designated by the numerals 15, 17 and 19 respectively, the opposite sides of the ridges being considered as valleys.
- the corrugated sheets are secured together in any conventional or convenient way as with a suitable cement or glue.
- the gluing of the corrugated foils offers particular difficulties because of the different nature of contacting surfaces.
- the metal foils have to be glued to a nonmetallic or plastic film material with a waterproof and strong bond.
- this gluing can be executed by using a copolymer consisting of 87% vinyl chloride, 12% vinyl acetate and 1% maleic acid.
- To one part of copolymer is added five parts of isopropyl acetate or normal propyl acetate but other solvents may also be used.
- the presence of maleic acid causes an attack on the metal foils and results in a bond between the plastic and the metal that will not be affected by water.
- the corrugation or valley depth of the aluminum foils may, according to my invention, vary from A; to of i an inch and the corrugations of the plastic film may vary from a minimum of /s of an inch inch in depth.
- the plastic film material should preferably be of a non-inflammable character, as indicated by the materials mentioned above.
- the plasticizing agent if such a material is used, should be triphenyl phosphate and/or, tri-cresyl phosphate in order to render the material non-inflammable to the greatest possible degree.
- the thicknesses of the plastic film materials are between .001 to .003 inch, as set forth above, they will be pervious to long wave heat rays. For this reason an 2.1- plastic insulation board of corrugated film material having said thickness cannot be successfully used without incorporating in the plastic material a finely divided blocking substance such as graphite, usually in the amount of 35% by weight.
- FIG. 2 of the drawing where there is shown another embodiment of the invention.
- the board is illustrated as of two corrugated aluminum foils 2t and 21, separated by an interposed blanket 22 of fiber glass or similar material, the blanket having yielding fibrous surfaces and, although fibrous, it is of approximately uniform thickness throughout.
- the number of alternate layers of foil and fiber glass of which the board may be constructed is immaterial.
- the corrugated metallic aluminum foils are cemented or glued to the non-metallic, pervious spacing material in any conventional or convenient way along the ridges 23 and 24. This leaves the intervening valleys formed by the corrugations of the aluminum foil substantially free of the spacing material.
- the glue material already described above will be found suitable.v
- the range of thickness'of the aluminum foil is the same as mentioned above with the arrangement of Figure l and a suitable thickness of hard and bright aluminum foil is approximately .00065 of an inch.
- the corrugation height of the aluminum foils may in this modification of the invention vary from A2 of an inch to /4 of an inch.
- the fiber glass spacing material 22 should have a thickness not less than Mr inch and should not exceed 1 inch.
- the fiber glass blanket 22 should also be light in weight and have a weight per unit volume of not less than .5
- the fiber glass spacing members or blankets 22 are of a softness of texture or density of mass which will yieldingly support the aluminum foils in space relation under all conditions of handling and operation unduly subjecting the corrugations of the foils to distortion due to shocks or jars.
- the fiber glass foil spacing means or blanket 22 has a softness or resiliency of texture of a sufficiently light mass so that it will yield and then spring back in order to absorb pressures applied normally to the insulating board.
- An insulation board of this type is completely noncombustible and has a k-factor which is lower than that of an all-fiber glass insulation. Moisture migration by diffusion of water vapor in the transverse direction is practically inhibited by the numerous layers of metal foils and internal convection and radiation of heat is for the same reason minimized.
- the light weight heat insulation board of the character described has an extremely low k-factor when in a dry condition.
- the factor is comparatively little affected by a rise in the mean temperatures of the insulation and is less influenced by moisture migration than are other hitherto known light weight insulation boards.
- An insulating board, constructed in the manner described, is also resilient, as to the fiber glass portion'while remaining relatively stiff as to the foil portion and is easy to handle and cut and can therefore be applied in complicated structures.
- a multi-layer heat insulating board the combina- ;-tion of a plurality of spaced impervious sheets of reflective metal foil each having corrugations extending paral- ,lel to each other, said sheets forming vapor, convection and radiation barriers, and a blanket of insulating material of substantial thickness disposed between said sheets and secured directly-to the apexesof the corrugatio ns and serving to provide insulation between foils, said corrugations being open and unobstructed whereby to provide drainage channels between the foil and the insulating material.
- a multi-layer heat insulating board the combination of a plurality of spaced impervious sheets of reflective metal foil each having corrugations extending parallel to each other, said sheets forming vapor, convection and radiation barriers, and a plurality of blankets of insulating material of substantial thickness disposed between said foils and secured directly to the apexes thereof and serving to provide insulation between the foils, said corrugations being open and unobstructed whereby to provide drainage channels for moisture condensed thereon.
