Definitions

  • the instant invention refers to a method of fabricating layered materials with at least one outside surface comprising a light metal sheet which is glued to a base of veneer, a compressed laminated product of wood, plywood, particle board or wallboard.
  • Layered materials made up of a sheet of light metal glued to a plywood plate are known in the art. They are characterized by comparatively great bending and breaking strength and are comparatively insensitive to impact.
  • the object of the instant invention is to further improve layered materials of this type.
  • the invention makes use of a sheet of light metal which at least on the side that is to face the plate of veneer etc. is provided with small waves, is granulated or is patterned in some other way.
  • the two adjoining surfaces are subjected to pressure forcing them against each other, said pressure being so great that the wavyness, granularity etc.
  • Said pressure should preferably be greater than about 213 pounds per square inch (15 kg./cm. and it should be retained until the glue joint has hardened.
  • light metal sheets of this type are applied to each side of a plate of veneer, etc., said sheets of light metal preferably being patterned or granualted on both sides.
  • gluing it would be preferable to use a glue of phenol, resorcinol or carbamide type, said glue being applied to the surface of the wallboard or plywood etc., whereas the metal surface after being degreased and somewhat roughened, for instance by pickling with a solution of caustic soda or by sand blasting, is provided with a coating of an appropriate composition of casein latex. If desired, the sheet thus pretreated can be coated with the same type of glue as the surface of the wallboard etc. after said composition has dried.
  • glue of the above-mentioned type it would also be possible to use a contact glue made on the basis of natural rubber or on the basis of synthetic rubber, for instance neoprene. In this case both the joining surfaces would be coated with the contact glue in question after cleaning and finishing or sandblasting, respectively.
  • FIG. 1 shows a large portion of a sheet or base plate 1 of veneer, which on both sides has been provided with coatings 2 and 3 in the form of sheets of perforate, granulated light metal.
  • FIG. 1 is to illustrate the utilization of a glue of contact type.
  • the lower light metal sheet 3 is already attached to the bottom side of the veneer 1, whereas a corner 4 of the upper light metal sheet 2 has not yet been pressed against the underlying veneer.
  • FIG. 2 shows a portion of the layered material of FIG. 1 after the metal sheets and veneer have been pressed together. It will be seen that the waves or the granulaite States Patent tions on the insides of the light metal sheets 2, 3 have provided a permanent deformation in the wallboard 1 as a result of the pressure.
  • Example 1 A layer of birch plywood is cleaned and smoothed and is coated on both sides with a glue of phenol type.
  • the glue can be spread out manually either by means of a spatula or a brush or by spreading rollers.
  • the two plywood surfaces pretreated in this manner are then to be provided with light metal sheets granulated on both sides, so called embossed stucco sheeting.
  • the two surfaces of the light metal sheets facing the plywood are treated in the following manner: They are first cleaned from grease, for instance by means of a weak alkaline solution, and may thereafter be sand blasted if desired, if the pickling provided by said solution is not satisfactory for the adhesion.
  • the surfaces pretreated in this manner are then coated with an appropriate composition of casein latex, for instance by means of a brush. After this composition has dried and resulted in a layer adhering with great strength to the sheet surfaces the light metal surfaces which have been pretreated in the manner disclosed above are pressed against the glued surfaces of the plywood after these have dried to sticky condition.
  • said layer of casein latex can be provided with a layer of phenol glue before the joint surfaces are brought together.
  • the light metal sheets and the plate of veneer are pressed together in a press having so high pressure that the granularities in the two light metal sheets result in a permanent deformation in the two faces of the plywood, said deformation not only increasing the adhering area in the joint but also giving exceptionally good qualities of strength to the completed layered plate.
  • the pressure is adjusted with respect to the hardness of the birch plywood.
  • the preferable pressure for birch plywood of average quality would be about 286 pounds per square inch (20 kg./cm. A slightly lower pressure could be used for pine plywood. About 213 pounds per square inch (15 kg./cm. would be satisfactory in this case.
  • An appropriate granularity of the light metal sheet would be about 4-20 mils (0.1-0.5 mm.) depending on the thickness of the layered plates which are to be fabricated and on the deformation which can be permitted in the intermediate layer.
  • the metal sheet must be sufficienlty dense, strong or thick so that the granulations formed on at least one surface remain as granulations while the sheet and base plate are pressed together, the granulations passing into the surface of the less dense base plate and causing a deformation of the latter.
  • Example 2 A particle board plate is cleaned and smoothed on one side and coated with a glue of neoprene type. Coating can be effected by means of a spatula or the particle board plate can be passed under a spreading roller. A granulated surface sheet metal plate is to be made to adhere to the particle board plate surface treated in this manner. The sheet metal plate is cleaned on its surface facing the particle board plate by an appropriate degreasing agent, for instance carbon tetrachloride, trichloroethylene or a 5 percent solution of caustic soda. In this case the work must be effected under appropriate airing conditions.
  • an appropriate degreasing agent for instance carbon tetrachloride, trichloroethylene or a 5 percent solution of caustic soda. In this case the work must be effected under appropriate airing conditions.
  • the metal surface is roughened slightly, for instance by sandblasting, and said surface is then coated with a glue of neoprene type.
  • glue applied to both the particle board plate and the metal plate has dried so much that the surface does not stick to ones fingers the two surfaces are brought together, care being taken that said two surfaces are centered to the required extent with respect to each other.
  • the layered plate is subjected to so great a pressure, that the granularities of the light metal sheet are pressed into the particles of the particle board plate thus deforming the surface of the particle board plate.
  • An appropriate pressure would also in this case be between about 213 and 286 pounds per square inch (20 kg./cm.
  • a method of fabricating a double layer material composed of an imperforate metal sheet, having at least one granulated surface, and a base plate formed from a less dense non-metallic material comprising applying adhesive to the granulated surface of the sheet and to the surface of the base plate which will be in contact with the metal sheet, and
  • a method of fabricating a multi-layer material having both outside surfaces composed of an imperforate metallic sheet, each sheet having at least one granulated surface, and a base plate located therebetween formed from a less dense non-metallic material comprising applying adhesive to both surfaces of the base plate and to the granulated surfaces of the two metallic sheets which will be in contact with the base plate,
  • said pressure being sufiicient to cause the granulations on the surface of each metallic sheet to penetrate through the adhesive and into the surfaces of the base plate, developing in the latter a permanent deformation of material.
