(54) METHOD FOR MAKING DECORATIVE EMBLEMS
(71) We, THE D.L. AULD COMPANY, a corporation organised under the laws of the State of Ohio, United States of America, of 1209 North Fifth Street, Columbus, Ohio,
United States of America, do hereby declare the invention for which we pray that a patent may be granted to us and the method by which it is to be performed to be particularly described in and by the following statement:
Decorative plaques and emblems (herein generically called "emblems") are widely used throughout a number of industries. In the past a colored vitreous frit was flowed into a bronze substrate and fired at 12500F. The glass-like vitreous enamel served to beautify the product and protect the decorative emblem from weathering should the plaque or emblem be exposed to the environment.Today plastics are primarily used for producing plaques and emblems.
For example, in Loew (U.S. patent 3,654,062) there is disclosed a process of injection molding a decorative "Mylar" ("Mylar" is a Registered Trade Mark) facing sheet over a vinyl plastic body. The emblem is coated with a layer of protective varnish on the outer surface of the facing sheet. Other molding processes, such as compression molding (either one or two shot), are also well known in the art. See for instance, U.S. patents 2,244,565; 2,931,119; 3,075,249; and 3,114,597.
Likewise, polyurethane molding compositions are also well known in the art. Thus, U.S.
patents 3,337,476; 3,391,101; and 3,393,243 disclose polyurethane compositions. Patent
No. 3,391,101, then, states that the compounds disclosed therein may be "poured into the mold as a liquid" (Col. 1, lines 49-50); although, this is actually in the context of sealing a pipe rather than producing a molded product. None of these patents disclose casting a polyurethane upon a substrate to produce a decorative emblem.
It is an object of this invention to provide an improved method of making decorative emblems by casting a clear (possibly tinted), hard plastics material, resembling and suitable as a substitute for vitreous enamel, onto decorative foil shapes to be mounted on a base.
The invention consists in a method of making decorative emblems comprising a base which carries a decorative foil shape onto which a clear, hard plastics composition is cast, com rising:
(a providing a series of flat decorative foil shapes each having a top and bottom surface and having sharply defined peripheral sides which intersect with said top surface, and having an adhesive coated on its bottom surface,
(b) holding said series of foil shapes flat and horizontal on a support surface and free from surrounding side walls,
(c) casting a measured amount of said plastics composition in liquid form directly onto the top surface of each of said foil shapes so that it flows to said sharply defined peripheral sides and forms a positive meniscus without flowing over said sharply defined peripheral sides,
(d) curing said plastics composition while maintaining said foil shapes flat and horizontal, whereby said cured plastics composition produces a clear, hard plastics layer providing a lens effect to the top surface of said foil shapes onto which it has been cast, and
(e) utilising said adhesive coated bottom surface of said foil shapes to adhere said foil shapes with the hardened plastics composition cast thereon onto a base.
The foil shapes (discs, oval or otherwise) may comprise a metal foil, of from 0.001 to 0.010 inch thick. Colors, information or other decoration may be applied to the foil by lithography, silk screening or other methods normally used to decorate metal. The foil shapes may be embossed or raised in selected areas. The foil can also be a plastics material such as "Mylar", polyethylene, polyethylene terephthalate, and may be plain or embossed.
The cast plastics material, when cured, gives a lens effect to each individual decorative shape. The preferred plastics composition is a polyurethane composition although it is possible to use other castable plastics materials capable of forming a clear, hard plastics layer, resembling vitreous enamel, having a meniscus and giving a lens effect.
The polyurethane-type compound is preferably produced by the reaction of polypropylene glycols with an aliphatic diisocyanate. To facilitate the application of the chemicals in the product, the glycols and diisocyanate are compounded into an easily handled two-part product. The two parts are then mixed in proper proportion, degassed to remove air bubbles and then poured onto an emblem surface to form a clear, hard plastics material.
A preferred embodiment of the method of this invention will now be described with reference to the accompanying drawings, in which:
Figure 1 is a partial perspective view of a casting operation,
Figure 2 is a cross-sectional view of a disc with plastics material cast thereon, and
Figure 3 is a view similar to Figure 1 and showing what happens if the disc has a rounded edge.
One of the features of this invention is the formation of a clear, hard plastics material for use as a substitute for vitreous enamel. The preferred material is a polyurethane-type compound. It involves basically a reaction between an isocyanate material and a polyol to form a urethane polymer. This is a fairly simple addition process which, when extended to difunctional or polyfunctional reagents, provides a direct route to polymers. The hydrogen on the nitrogen atom of the urethane group is capable of reacting with more isocyanate to form allophanates which provide the means of introducing branching or cross-linking in the polyurethanes. The reaction provides a bond high in thermal stability and resistant to hydrolysis.
In the instant process, a polyurethane compound is produced by the reaction of polypropylene glycols with an aliphatic diisocyanate. To facilitate the application of the chemicals in production, the glycols and diisocyanate are compounded into an easily handled two-part product.
The first part, Part A, which is the polyol component of the two-part system, is made by mixing a difunctional, trifunctional and/or tetrafunctional polypropylene glycol, adding suitable catalyst, surface active agents and light and heat stabilizing agents.
The polyol component, Part A, is prepared from polypropylene glycols which have two, three, four or more hydroxyl groups per molecule or any combination of these. The polyols are combined with a catalyst, ultraviolet absorber, antioxidant and surface active agent.
After combination, the product is heated to 90"C under twenty-nine inches of vacuum for one hour, cooled to room temperature and packaged. A typical formula is as follows:
Part A Parts by Weight
Polypropylene glycol (triol)- TP-440 77.57
Polypropylene glycol (diol) P-245 19.39
Catalyst (DBTDL) 1.00
Antioxidant (Naugard P) 1.00
Ultra-violet absorber (UV-317) 1.00
Surface active agent SF-69 .04
100.00
The amount of the catalyst (DBTDL) can range from 0.10 to 2.00; the amount of the antioxidant can vary from 0.25 to 2.00; the amount of the ultra-violet absorber (UV-317) can vary from 0.25 to 2.00 and the amount of the surface active agent SF-69 can vary from 0.01 to 0.10.
The molecular weight of the triol can vary from 300 to 3000 and the molecular weight of the diol can vary from 400 to 2000.
The other part, Part B, which is the diisocyanate component of the two-part system is prepared by reacting an aliphatic diisocyanate with a polyol, di, tri or tretrafunctional in nature to form a quasi prepolymer. The purpose of the prepolymer is to control the viscosity and ultimate reaction rate of Part A with the diisocyanate Part B. The dry polyol, -di, tri, and tetrafunctional is mixed with the diisocyanate and heated slowly to 90"C for one hour under twenty-nine inches of vacuum and then cooled to room temperature, drawn off and packaged. A typical formula is as follows:
Part B Parts by Weight
Polypropylene glycol (triol) TP-440 15.00 "Hylene"W (diisocyanate) 85.00
("Hylene" is a Registered Trade Mark)
100.00
The molecular weight of the triol can vary from 400 to 2000 and the "Hylene" has a large
range.
Tetrols can be substituted for triol in either Part A or Part B. Any suitable diol can be used.
The catalyst can be any heavy metal compound of the group of tin, lead, zinc, mercury,
bismuth, cadmium, antimony, etc. A suitable antioxidant yielding a colorless compound
can be used. Ultra-violet absorbers soluble in polyol and clear in the final product are
suitable. The surface active agent is a silicone compound and can be one of many
compounds.
Hylene W is an aliphatic diisocyanate available from E.I. duPont de Nemours & Co.
Substitutes for it are hexamethylene diisocyanate, xylene diisocyanate, cyclohexyl
diisocyanate or any light stable (saturated) diisocyanate.
After Part A and Part B are prepared as stated, the two parts are then mixed in the
proper proportion, degassed to remove air bubbles and poured onto an emblem surface to
form a clear, hard plastics material. The cure can be accelerated by the addition of heat.
The polypropylene glycol (diol) and the polypropylene glycol (triol) are commonly
available on the market, and for example, can be those manufactured by the BASF
Wyandotte Corporation as P-410 and TP-440, respectively. P-410 is listed by BASF
Wyandotte as a "Pluracol" (Registered Trade Mark) polyether diol having a molecular
weight of 425 (calculated from hydroxyl number), an OH No. of 265, a viscosity at 25"C of
75 cps, and a pH of 6.5. TP-440 is listed by BASF Wyandotte as a polyether triol having a
molecular weight of 425 (calculated from hydroxyl number), an OH No. of 398, a viscosity
at 25"C of 600 cps and a pH of 6.5.
The two parts, Part A and Part B, are mixed in the following proportions by weight:
Part A 44.50
Part B 55.50
100.00
This is the preferred proportion, although the proportions can vary from 40-50% for Part
A and from 60-50No for Part B.
The resulting urethane compound is 100 percent solid and clear and is stable under
sunlight and weathering. The preparation of a hard, glass-like, colorless polyurethane by
the use of triols and tetrols modified with diols for elasticity is believed novel as is the use of
an antioxidant to help stabilize a polyurethane.
The components of the polyurethane composition, namely a polyether polyol (which may
comprise a mixture of a polyether diol and a polyether triol) and a diisocyanate are conveniently mixed in an apparatus as described with reference to Figure 1 of our
co-pending application No. 29083/77 (Serial No. 1587833) from which the present
application is divided. A measured amount of the composition in liquid form is cast directly
onto the top surface of each foil shape, for example by the technique shown in Figure 1
wherein a vacuum chuck 139 holds a sheet of release paper 140 thereon through a vacuum
being created underneath the sheet. Chuck 139 has a plurality of holes therein (not shown) through which the vacuum is applied. A series of metallic foil discs 141, 142, etc. are placed on the sheet.The discs have been lithographed or silk screened on their top surface and have an adhesive on the bottom surface thereof. The operator or automatic machine utilizes dispensing head 143 with nozzle 145 and supply line 144 to dispense a measured amount of the composition atop and onto each disc. The dispensing head 143 regulates the amount.
The discs are similar to the disc 127 of Figure 2 insofar as each has a sharply defined peripheral side which intersects with the top planar surface. The cast composition is cured and cooled and the ornamental design on the top of the disc is enhanced by the "lens effect" created by the cast composition.
It is important to keep the foil material shapes flat and horizontal during the casting and curing process. The shape can be a plastics foil, a metal foil, paper foil or "Mylar" foil. A design can be embossed therein prior to casting. In the technique shown in Figure 1, the discs are spaced to avoid any static charge attraction between the discs as the material is cast thereupon.
Figure 2 shows a flat metal foil disc 127 having perpendicular peripheral sides 128, 130.
The cast plastics material is flat on top and slopes down to form a positive meniscus. D represents the diameter of the disc, Y the'height of the plastics material and W the height of the disc. Test results of a disc where Z is 0.020 inch are as follows
D in inches Y in inches
0.25 .030
0.50 .075
0.75 .100
1.00 .125
1.50 .125
In the table, Y represents the maximum height that the material may achieve without flowing over the periphery of the disc. Applications of more liquid on disc 127 than denoted in the Y column results m liquid overflows due to a break in surface tension. Overflow results in thinner film sections. The compound was applied at a disc temperature of 72"F.
When a free body of liquid, such as the compound described herein, is at rest on a solid, the degree of flatness on the top surface of the liquid is a function of the condition at the edges where the liquid contacts the solid. If the wettability characteristics of the liquid are such that liquid does not "wet" the solid, it indicates that the liquid particles attract each other more than the solid particles attract the liquid particles. That is, the cohesive forces of the liquid are greater than the adhesive forces of the solid and liquid. This condition of the liquid is called the "meniscus". The meniscus formed by the instant compound when it is applied to a flat surface results in a lens effect. The lens effect is exploited by applying the compound to a painted or decorated surface to increase the aesthetic values related to depth, clarity and brilliance.These characteristics are used to produce the foil-backed inserts.
Figure 3 shows what happens when the condition of the disc edge is not perpendicular. A disc 133 has a perpendicular edge 134 and a rounded edge 135. The material 136 will stay on the disc at 137 adjacent the perpendicular edge 134 and runs over the rounded edge 135 as at 138.
The cured cast material has the property of hardness without brittleness and withstands heavy abuse from strong detergents and impact. It can withstand rigid water and humidity tests, salt and acid tests, hot and cold temperature tests, and gas tests. Thus, it is an excellent filler material for painted decorative parts.
The cured material has a shore "D" hardness of 80-85 and a specific gravity of 1.06. The component Part A has a viscosity of 375 cps, although the cps (centipoise) can vary from 300 to 1000, 2 RPM RVP Brookfield #4 spindle at 250C; 390 cps (300 to 1000 cps is the range) 20 RPM RVP Brookfield #4 spindle at 25"C. Component Part B's viscosity is 500 cps 2 RPM RVP Brookfield #4 spindle at 250C, 20 RPM RVP Brookfield #4 spindle at 25"C. Component Part A has a specific gravity of 1.05 and component Part B has a specific gravity of 1.07.
Again the mixing ratio, by weight, is approximately 45 parts of Part A and 55 parts of
Part B. The mixing ratio, by volume, is one part of Part A to one part of Part B. The volume tolerance should not vary from plus or minus one-half part. The gel time for the mixed parts is approximately two minutes and ten seconds, although the range is from two to seven minutes at 1500F. If a high crown or bulge on the top of the cast emblem is desired, it can be cured at room temperature up to 200"F for a longer period.
The decorative part must be free of moisture, grease, dust and other foreign matter. The part must be perfectly level and must be relatively flat. The component parts are mixed carefully and thoroughly in the mixing and casting head. The material should be mixed without entrapping air. If air bubbles do develop, the material should immediately be degassed. This is done by drawing a good vacuum on the material, releasing the vacuum, drawing another vacuum and releasing the vacuum again. The compound should be mixed, degassed and cast within the aforementioned gel time.
The plastics material is clear and, when cast, increases the clarity of the paint on the foil shape and enhances the details of the embossed and debossed areas. The surface of the cast material has a slight crown which assists the edge of the cast plastics material to blend smoothly to the foil shape, whether the latter be metal, aluminum or plastics. The material can be tinted with various colors, but excellent results are obtained with the clear cast which contrasts with the decorative metal and paint. The decorative foil shape with the hardened plastics composition cast thereon is finally adhered to a desired base by its adhesive coated bottom surface.
The invention provides improved decorative emblems. Because of the surface tension of the composition, the employment thereof in emblems creates a "lens effect", thereby enhancing the aesthetic effect of the emblem.
