Definitions
- the present invention relates to decorative inlaid sheet materials and the like. More particularly the invention is concerned with the use of polyvinyl chloride (hereinafter "PVC") polymerization agglomerates as decorative particles and their application on floor and wall covering substrates to produce realistic inlaid patterns, utilizing heretofore unobtainable design strategies and exhibiting superior properties.
- PVC polyvinyl chloride
- the particles can be spherical and, when such is the case, are hereinafter sometimes referred to as "pearls". These pearls can be random-sifted on the substrate or applied in geometrical patterns. Also disclosed is the use of mixes or blends containing transparent or partly transparent pearls allowing visible underprinting as a further strategy for unique design variations.
- Sheet materials in particular sheet vinyl flooring products, made with chips or particulate material, are commonly referred to as inlaids. These products and processes for their manufacture are well known in the floorcovering business and originate back to the early linoleum times where through patterned floorcoverings, based on linseed oil, cork dust and resins were developed by the industry. The process was later modified for vinyl.
- Vinyl inlaid floorcovering consists of coarse colored particles, such as chips or dry blends, which are "laid on” a substrate and then sintered by heat, or "laid in” a transparent liquid or solid matrix and fused by heat.
- the chips are produced from pre-gelled or fused spread, calendered or extruded compounds cut into geometrically regular profiles or ground into randomly shaped particles.
- the dry blends are made by mixing fine PVC powder with plasticizer, filler and color pigments and heating above the PVC compound's softening temperature.
- the small original particles "grow” and form a loose, porous, coarse, fluffy mass.
- the inlaid floorcoverings are normally characterized as those which maintain their decorative appearance as the surface is worn or abraded away. This characteristic makes such products particularly suitable for use in commercial areas where significant wear is encountered.
- Resilients include a substantially continuous layer of foam and are usually made by incorporating solid particulate material into a plastisol coating, followed by gelling and fusing.
- Non-resilients do not contain a foam layer and usually are made by sintering and/or calendering, or otherwise compacting, particulate material.
- non-resilient products commercially offered are those containing large (about 3 mm, i.e 1/8 inch) square chips in a clear matrix and those containing small (about 0.1 mm, i.e 0.004 inch) dry blend resin particles made by sintering and/or compacting normal dry blend resins. It is believed that the reason no products containing chips, granules, or particles of an intermediate particle size, for example ranging from 0.1 to 1.0 mm (0.004 inch to 0.040 inch), are offered results from limitations inherent in current inlaid manufacturing technology, discussed more fully hereinafter.
- Resilient inlaids are usually made by embedding ground plastic particulate material in a plastisol coating.
- US-A-4,212,691 exemplifies such product and methods for their manufacture.
- the thickness of the particles of the decorative chips or flakes is stated to be from about 0.075mm (3 mils) to about 0.62mm (25 mils): see for example column 7, lines 62-64.
- the products disclosed all contain embedded chips or flakes ground from plastic sheet stock, even when chips or flakes from other stock materials are added (eg. see column 8, lines 4 et seq). These chips or flakes characteristically have a high aspect ratio (ie. length/thickness).
- US-A-3,239,364 which discloses pressing solid particles into a printed base coat
- US-A-4,440,826 which discloses a product in which transparent chips are pressed into an opaque layer until they create windows exposing a printed layer below.
- US-A-4,196,243 discloses particles incorporated into a wearlayer so as to provide a non-slip wearlayer over a pigmented rather than printed base.
- US-A-4,450,194 discloses decorative coverings for floors and walls in which resin particles are used to provide differentials in gloss and texture.
- This document discloses an arrangement in which a vinyl plastisol ink is applied to selected areas registering with a printed image applied to a substrate. Resin particles are applied and adhere to the plastisol ink in the selected areas only.
- a top layer of PVC plastisol over the entire product provides a smooth surface outside the selected areas but leaves the particles projecting above the surface in the selected areas, thus giving selected areas of greater texture and lower gloss. In between these areas, the surface is smooth.
- products formed by compacting or sintering dry blends have always shown limited particle distinction due to process limitations and available particle sizes.
- the particles tend to lose their identity due to agglomeration or lumping caused by sintering process.
- a decorative, inlaid floor or wall covering product which incorporates as the essential elements thereof (i) resinous particles having an aspect ratio significantly lower than those currently employed in inlaids commercially offered in the United States, (ii) an adhesive matrix in which said particles are embedded, and (iii) a substrate which supports these over a print layer which is visible through the adhesive matrix layer.
- the invention provides a decorative, inlaid floor or wall covering in the two forms as claimed in the claims
- the particles have a size within a range from 0.1 to 1.0mm (0.004 to 0.04 inch).
- the particles employed in this invention have as aspect ratio of no greater than 1.5:1.
- Particles having an aspect ratio of about 1:1 and, in particular, particles which are also spheroidal, are especially preferred because of the excellent results achieved therewith, as discussed more fully hereinafter.
- the use of particles which are essentially as thick as they are flat, ie. having a low aspect ratio provides a product that will not lose its pattern due to wear in use, thus preserving the unique property which characterizes true inlaids.
- a decorative, inlaid floor or wall covering which comprises:
- the inlaid products of this invention offer unique design advantages. Further, cost advantages can also be realized by utilizing raw materials which are believed to be unique to inlaid manufacture.
- certain of the novel products of the invention incorporate an adhesive matrix consisting essentially of a plastisol layer containing a high loading of transparent and/or transluscent and colored, spheroidal resinous particles, which, preferably, range in size from 0.1 to 1.0 mm (0.004 inches to 0.040 inches). When this matrix is applied over a printed pattern, a unique visual effect is produced.
- Such particles can be made in uniform controlled sizes by employing technology described in United States Patent 3,856,900.
- special large particle size dry blend resinous particles either screened to the desired size ranges of this invention from oversized material obtained from normal production variations, or specially made particles in the desired size range, can be utilized.
- Another, and preferred, embodiment of this invention is a decorative, inlaid floor covering which comprises:
- the product is comprised of a base supporting material, which, optionally, may be precoated with a plastisol to enhance printability, a print layer offering decoration, and an adhesive matrix containing transparent and pigmented resin particles, which are preferably spherical or spheroidal.
- the resulting product has an additional coating on its top surface to enhance surface properties, such as gloss and the like, and insure there is no residual porosity resulting from the process of embedding the particulates in the adhesive matrix.
- One of the advantages of this invention is that it employs ingredients and processing technology well known to those skilled in the art. Also, by employing a fluid plastisol as the matrix material binding the particles together, the product can be manufactured without the need for the high pressures or temperatures characteristic of the calendering or agglomeration steps of the prior art processes. This processing characteristic also distinguishes the subject process from those of the prior art which employ only dry blend resins, which are agglomerated through heat sintering.
- the substrate is a relatively flat fibrous or non-fibrous backing sheet material, such as a fibrous, felted or matted, relatively flat sheet of overlapping, intersecting fibers, usually of non-asbestos origin.
- the substrate can, if desired, be asbestos or non-asbestos felts or papers, woven or non-woven; knitted or otherwise fabricated textile material or fabrics comprised of cellulose, glass, natural or synthetic organic fibers, or natural or synthetic inorganic fibers, or supported or non-supported webs or sheets made therefrom or filled or unfilled thermoplastic or thermoset polymeric materials.
- the substrate or base material can be coated to improve the print quality of the substrate.
- coatings can be plastisols, organosols, lacquers, filled or unfilled latex coatings, or other coatings conventionally employed as preprint sealants in the manufacture of floor or wall covering products.
- plastisol is intended to cover a relatively high molecular weight polyvinyl chloride resin dispersed in one or more plasticizers.
- the plastisol upon heating or curing forms a tough plasticized solid.
- plastisol compositions are intended to include organosols, which are similar dispersed polyvinyl chloride resin materials that, in addition, contain one or more volatile liquids that are driven off upon heating.
- the substrate coating employed in the products of this invention is a resinous polymer composition, preferably, a polyvinyl chloride plastisol which is substantially uniformly applied to the substrate surface, for example by means of a conventional reverse roll coater or wire wound bar, eg. a Meyer Rod Coater, wherein the grooves provided by the wires assist in metering the flow of the plastisol.
- a conventional reverse roll coater or wire wound bar eg. a Meyer Rod Coater
- any suitable coating means can be employed.
- Exemplary of other coating means are knife-over roll coater, rotary screen, direct roll coater and the like.
- the thickness of the resinous polymer composition or plastisol, as it is applied to the surface of the substrate, is substantially uniform, and is preferably in the range of 0.075 mm to 0.75 mm (3 mils to 30 mils).
- the substrate can be thinner or thicker as may be required by the particular product application.
- the preferred and typical substrate coating is a polyvinyl chloride homopolymer resin
- other vinyl chloride resins can be employed.
- Exemplary are a vinyl chloride-vinyl acetate copolymer, a vinyl chloridevinylidene chloride copolymer, and copolymers of vinyl chloride with other vinyl esters, such as, vinyl butyrate, vinyl propionate, and alkyl substituted vinyl esters, wherein the alkyl moiety preferably is lower alkyl containing between about 1-4 carbons.
- suitable synthetic resins such as polystyrene, substituted polystyrene, preferably wherein the substituents are selected from the group consisting of alkyl (C 1 -C 10 , preferably C 1 -C 4 ), aryl (preferably, C 6 -C 14 ), polyolefins such as polyethylene and polypropylene, acrylates and methacrylates, polyamides, polyesters, and any other natural or synthetic resin capable of being applied to the substrate or base coatings of this invention to provide a smooth and uniform surface and/or to improve the print quality of the substrate or base coating surface, are also applicable; provided such resin is otherwise compatible with the overall product composition and, therefore, within the principles of this invention.
- Organosols and aqueous latices are also of use, employing as the dispersing or suspending media, organic solvents and water, respectively, rather than plasticizers, as in the case of a plastisol.
- plasticizers which can be used are dibutyl sebacate, butyl benzyl sebacate, dibenzyl sebacate, dioctyl adipate, didecyl adipate, dibutyl phthalate, dioctyl phthalate, dibutoxy ethyl phthalate, butyl benzyl phthalate, dibenzyl phthalate, di(2-ethylhexyl) phthalate, alkyl or aryl modified phthalate' esters, alkyl, aryl, or alkylaryl hydrocarbons, tricresyl phosphate, octyl diphenyl phosphate, dipropylene glycol dibenzoate, dibasic acid glycol esters, and the like.
- a blowing or foaming agent such as azodicarbonamide (if a blowing or foaming procedure is desired), conventional stabilizers/ accelerators, initiators, catalysts, etc., such as zinc oleate, dibasic lead phosphite, etc., conventional heat or light stabilizers, such as metallic soaps, etc., UV absorbers, colorants, dyes or pigments, notably, titanium oxide, solvents and diluents, such as methyl ethyl ketone, methyl isobutyl ketone, dodecyl benzene, etc., fillers, such as clay, limestone, etc, viscosity modifiers, antioxidants, bacteriostats and bacteriocides, and the like.
- azodicarbonamide if a blowing or foaming procedure is desired
- conventional stabilizers/ accelerators, initiators, catalysts, etc. such as zinc oleate, dibasic lead phosphite, etc.
- Suitable inks include those normally used in the manufacture of floor covering, preferably resilient floor covering. These include plastisol, solvent based systems and water based systems. Such systems can include a chemical suppressant in those cases where the substrate to which the ink is to be applied is a foamable plastisol or organosol. Such suppressants are well known in the art (eg. see US-A-3,293,094).
- Printing onto the substrate can be effected by rotogravure, flexigraphic, screen printing, or other printing techniques conventionally employed in making floor or wall covering products.
- the adhesive layer is normally a plastisol or organosol additionally containing a plasticizer system, associated diluents, viscosity control aids and stabilizers. Those discussed above are exemplary. When underprinting is present, the adhesive would not normally contain colors or pigments which would render the adhesive layer opaque.
- the resinous particles of this invention can be of various sizes and geometric shapes, spherical and essentially spherical, (sometimes referred to herein as "spheroidal") being especially preferred as having the low aspect ratios discussed herein required to obtain the desirable design effects this invention is capable of providing.
- Each transluscent or opaque particle can contain its own individual colorant, dye or pigment. It may be preferred that in some embodiments of this invention at least some of the particles are sufficiently transparent or sufficiently transluscent, to permit the printing on the print layer to show through the particles concerned.
- discreet spheroidal particles is advantageous for enhanced visual effect of depth and improved wear characteristics.
- Illustrative of those spheroidal particles which are especially preferred are the particles and the methods for their manufacture taught in US-A-3,856,900. This procedure is particularly convenient for the production of relatively small plastisol beads or "pearls" having a particle size of generally about 0.75mm (0.030 inch) or smaller.
- Particles can also be obtained by screening the oversized particles from normal suspension grade resin production or by making special particle sizes, for example, in accordance with US-A-3,856,900. Particles in this size range are particularly useful for achieving certain desirable design effects. Such procedures are also capable of making smaller particle sizes. (eg. see US-A-3,345,235), but in the case of spheroidal particles, the procedure of US-A-3,856,900 is preferred.
- the particles employed in this invention can have a wide variety of geometric shapes, provided that the aspect ratios of such particles fall within the ranges discussed herein.
- Exemplary of other geometric outlines are squares, triangles, circles, annuli, other polygons, etc, or irregular sizes and shapes, or a mixture of any or all of such shapes, including spheroidal.
- the size of the particles employed in carrying out this invention have a pronounced effect on the results obtained.
- Use of relatively small particles eg. ranging from about 150 ⁇ m (100 mesh) to about 600 ⁇ m (30 mesh) are most advantageous in producing the desired design effects.
- the ratio of transparent to colored particles determines the visibility of the printed pattern underneath the resulting adhesive matrix. Generally, 50% or less, and preferably 0-30 %, transparent to colored particle loading is preferred. The amount actually used will, of course, depend upon the type of end-use application and design effect desired. Good results have even been achieved in the range of 0-10% transparent to colored particle loading.
- the optional overcoat or wearlayer is preferably a plastisol of the same or similar type as that discussed above in connection with the resins employed in the substrate coat and the adhesive layer or matrix.
- the formulations generally include materials to enhance special specific properties, for example gloss, wear, stain resistance, and scuff resistance.
- top coating Suitable for use as a top coating can be employed.
- exemplary are wear resistant polyurethanes, such as those described in US-A-4,087,400.
