Price, Richmond, Va., assgnor to Reynolds Metals Company, Richmond, Va. Filed Dec. 7, 1970, Ser. No. 95,835 Int. Cl. B32b 31 /18 U.S. Cl. 156-254 12 Claims ABSTRACT OF THE DISCLOSURE A matte finish is provided on a desired surface by the heating and compressing of a fluorocarbon coating to the desired surface so that the coating is secured thereto. Thereafter, the coating is split between opposed sides thereof so that one split part of the coating remains on the surface to provide the matte finish thereon and the other split part of the coating is removed from the surface.
BACKGROUND OF THE INVENTION SUMMARY This invention provides an improved method for making a matte finish on a desired surface in a simple and effective manner, this invention also providing a member for forming the matte nish as well as the matte finished article.
In particular, one feature of this invention provides a member for providing a matte finish to a desired surface wherein the member is adapted to be pressed into heat contact with the desired surface and, therafter, be readily released from that surface while providing a matte finish thereto.
One method of this invention comprises the method steps of disposing a coated side of a finish producing member against the desired surface with the coating being a material that is adapted to become secured to that surface and readily split between opposed sides thereof, causing the coating of the one side of the member to become secured to the surface and, thereafter, separating the member from the surface intermediate the opposed sides of the coating so that the coating splits and leaves a layer thereof on the surface to provide the desired finish thereof.
Other details, uses and advantages of the invention will become apparent as the following description of the present preferred embodiments thereof in the accompanying drawing proceeds.
BRIEF DESCRIPTION OF THE DRAWING The accompanying drawing shows schematically the present preferred embodiments of the invention, in which:
FIG. l is a schematic view, partially in cross section, illustrating one embodiment of the method of this invention for forming a matte finish on a strip of material.
FIG. 2 is an enlarged, fragmentary, cross-sectional View illustrating the inlet side of the heating chamber of FIG. l.
FIG. 3 is a view similar to FIG. 2 and illustrates the exit side of the heating chamber of lFIG. 1.
FIG. 4 is a fragmentary, cross-sectional view illustrating another method of this invention for forming a matte finish on a desired surface.
DESCRIPTION OF ILLUSTRATED EMBODIMENTS Referring now to FIGS. 1, 2 and 3, one embodiment of the method of this invention is generally indicated by the reference numeral 10 and comprises a housing or frame structure 11 defining a heating chamber 12 therein with the housing 11 having an inlet 13 at one end thereof and an outlet 14 at the other end thereof for permitting sheet material to be passed through the housing 11 to be heated in the chamber 12 thereof and be compressed by suitable pairs of opposed roller means 15 and 16 spaced and disposed throughout the chamber 12 in the desired number and manner with one or more of the rolls 15 and 16 of each pair being urged toward the other with a desired pressure for a purpose that will be apparent hereinafter.
A first sheet of material 17 is adapted to be fed from a supply roll 18 thereof past a suitable guide roll 19 and be combined with another sheet of material 20 also being fed from a supply roll 21 thereof and past a guide roll 41 so that the two sheets of material 17 and 20 can be brought together at the entrance 13 to the housing 11 and be passed through the nips of the roller means 15 and 16 throughout the length of the chamber 12 to exit from the outlet 14 thereof. The sheet 17 is separated from the sheet 20 at the outlet 14 and is passed by a suitable guide roll 22 to a desired location while the sheet 20 passes by a guide roll 23 to a desired location, such as to a windup roll to provide a supply roll thereof.
The sheet of material 17 of this invention is so constructed and arranged that the same is adapted to impart a matte finish to the facing side 24 of the sheet of material 20 as the same are heated and compressed together in the housing 11 so that when the sheets 17 and 20 are subsequently separated at the exit side 14 of the housing means 11, the surface 24 of the sheet of material 20 is provided with a matte finish which has improved scuff resistance and has reduced water spotting characteristics as a result of a transfer to the surface 24 of part of a coating of the sheet of material 17 as will now be described.
The sheet of material 17 is best illustrated in FIGS. 2 and 3 and is a lamination comprising a paper sheet 25 secured to a metallic foil sheet 26 by an interposed adhesive layer 27, the metallic foil 26 comprising aluminum containing metallic material, if desired. The foil, adhesive and paper substrates 26, 27 and 25 provide a nonporous and thermally stable lamination which characteristics could be provided by other substances, if desired to practice this invention as hereinafter set forth.
The outer surface 28 of the foil sheet 26 of the lamination sheet 17 is provided with a coating 29 formed of particles of fluorocarbon selected from the group of fluorocarbon particles, such as tetrafluoroethylene, chlorotrifluoroethylene, dichlorodifiuoroethylene, trichlorofluoroethylene, and the like.
The coating 29 is adapted, when heated and pressed into contact with the surface 24 of the sheet 20 by the roller means 15 and 16 in a manner hereinafter described, to become secured to the surface 24 of the sheet 20 so that when the sheets 17 and 20 are subsequently separated from each other at the exit 14 of the housing 11, the coating 29 will split between the opposed surfaces 30 and 31 thereof whereby a part or layer 32 of the coating 29 remains secured to the sheet 17 and the remaining split part or layer 33 thereof remains secured to the surface 24 of the sheet 20 to provide the matte finish thereon,
some of the particles of the coating 29 splitting in two so that part thereof remains secured to the sheet 17 and the other part thereof remains secured to the sheet 20. In this manner, the split part or layer 33 of the coating 29 provides the desired matte finish 33 on the desi-red surface 24 of the sheet 20.
While the sheet 20 can be any desired surface, typical examples of the sheet 20 include resin impregnated paper and berboard used as an overlay on a wood, metallic or plastic base so as to provide furniture veneer, counter tops, desk tops, vertical wall panels and the like. Typical -resins include heat curing type resins such as melamines, phenolics, formaldehydes, expoxies, polyesters, and the like, as well as combinations thereof. Such matte nished materials are found to be scuff resistant on the matte surface thereof as well as have a reduced water spotting characteristic.
While the pressure being imparted to the sheets 17 and 20 to cause the coating 29 to become secured to the surface 24 of the sheet 20, as well as the temperature in the chamber 12 and the length of time the sheets 17 and 20 remain in contact with each other, are not critical values when practicing this invention, optimum results have been obtained using a pressure in a range from about 200 to 5000 pounds per square inch at a temperature in the range from about ambient temperature to 400 F. for a period of time from approximately three minutes to two hours. The pressure, temperature and contact time can vary with requirements relating to thickness of the substrates, curing time for the surface receiving the matte lfinish and types of material utilized.
Because of the use of the uorocarbon particles for the coating 29, not only is the matte finish provided for the desired surface in the manner previously described but also in the method of producing the matte nish after the heat and pressure have been utilized to secure the coating 29 to the sheet 20, the coating 29 readily releases by splitting the fluorocarbon particles so that the aforementioned difliculty in separating a particulate carrying member is substantially eliminated as the fluorocarbon particles provide good release from the desired surface.
While the method of this invention has been previously described as being performed with the sheet 20 and transfer sheet 17 being in roll form, it is to be understood that the transfer sheet or member 17 and the sheet or member 20 `receiving the desired finish on the surface thereof can by any desired structure and can be heated and compressed together while in a at configuration.
For example, reference is now made to FIG. 4 wherein another method of this invention is generally indicated by the reference numeral 34 and comprises a first member 35 having the side 36 thereof provided with a uorocarbon particle coating in the manner previously described and engaging against a desired flat surface 37 of another member 38 that is to receive the matte finish thereon in the manner previously described, the members 35 and 38 being of any desired thickness and being compressed together by cooperating die blocks 39 and 40 whereby after the coating on the surface 36 of the transfer member 35 has been secured to the surface 37 of the member 38, the members 35 and 38- are separated from each other by the iluorocarbon coating splitting therebetween so as to provide the matte finish on the surface 37 of the member 38 in the manner previously described.
Therefore, it can be seen that this invention not only provides an improved method of providing a desired finish on a desired surface, but also this invention provides an improved member for imparting the finish to a desired surface as well as an article having a matte finish on an exposed surface thereof.
While present preferred embodiments of the invention, and methods of practicing the same, have been illustrated and described, it will be recognized that the invention may be otherwise variously embodied and practiced within the scope of the following claims.
