Definitions
- the present invention relates to a method of manufacturing a carrier substrate for CV flooring, to a carrier substrate for CV flooring and to CV flooring.
- (cushion vinyl) flooring is in most cases also known as PVC flooring. More particularly, the present invention relates to the production of a carrier substrate made of mainly glass fiber and incorporating a novel barrier layer.
- the PVC flooring material comprises a substrate or a carrier substrate, which consists of woven or non-woven fabrics or rubber-impregnated paper.
- Woven fabrics are made of natural or synthetic fibres e.g. viscose, cotton, or hessian.
- Non-woven fabrics are made of synthetic or natural fibres e.g. viscose fibres bonded with polyvinyl alcohol, polyvinyl acetate or synthetic rubbers.
- the carrier material gives both strength and dimensional stability to the PVC flooring. Manufacturers produce most PVC floors by a process known as 'plastisol spread coating'.
- the PVC paste or so-called plastisol is applied in several layers of vinyl resin paste so that the floor is literally 'built up'.
- these include an impregnation layer, a foam core, a decorative layer, a clear protective wear layer and a foamed or compact back layer.
- the impregnation layer has a great importance to the final product quality as it forms a base for the other coating layers.
- the back layer which is face downwards on the laying of the flooring material, is normally of greater thickness than the top layer giving cushioning properties to the flooring. Manufacturers can build up complex patterns and three-dimensional effects through these layers and offer choice of styles and effects. The end results are sparkling, smooth and shiny surfaces.
- the preferred vinyl resin is polyvinyl chloride (PVC).
- the PVC plastisol paste may contain plasticisers e.g. diisononyl phthalate (DINP), di-(2- ethylhexyl)phthalate (DEHP), benzylbutyl phthalate (BBP) and diisoheptyl phthalate (DIHP), trixylenyl and tricresyl phosphates, stabilizers e.g. barium-cadmium soap, dibutyl tin dilaurate, dibasic lead carbonate, lead stearate, pigments, fillers e.g. CaCO 3 , viscosity depressants e.g. hexylene glycol, and solvents e.g.
- plasticisers e.g. diisononyl phthalate (DINP), di-(2- ethylhexyl)phthalate (DEHP), benzylbutyl phthalate (BBP) and diisoheptyl phthal
- the coatings may be applied using conventional techniques e.g. spreading knife, roller coaters, screen coaters, hot melt coaters and extrusion coaters. Plastisols are rapidly fused so that the layers can be applied at a high production rate. Finally a pattern may be printed on the foam core layer after fusing.
- a polymerised vinyl resin wear layer is provided on the printed layer, for example by coating with a vinyl resin paste.
- the wear layer may be transparent, coloured, mottled or have patterns embossed thereon.
- An additional polyurethane lacquer layer can be applied thereafter. Also other techniques like embossing and flake scattering are sometimes used to get special properties or effects to the final product.
- a floor covering is disclosed where the base sheet if formed of an impregnated asbestos felt, a resin impregnated cellulose or other organic felt, or an asphalt saturated organic felt.
- a prime coat made of latex possibly including pigments or fillers is applied on the felt to, for instance, improve the adherence of vinyl type compositions to the felt.
- the document further teaches that the prime coat is laid on the felt separate from the felt manufacture, and on such a surface of the felt that is further provided with the various coating layers including a wear layer, i.e. on the upper side of the felt, not on the surface facing the floor.
- the manufacture of the PVC floorings has remained substantially the same for decades.
- the only remarkable change, which has taken place, is, that very often felt or veil or tissue made predominantly of glass fiber has replaced the various carrier materials discussed above.
- the glass fiber tissue may be produced by any known mat-forming technique, including, for instance, so-called dry-laid, or wet-laid methods.
- the glass fiber products which may be used in the manufacture of PVC floorings, will be discussed in more detail.
- the products are, for the most part made of glass fibers, whereby the remaining fibrous part of the products may be made of both natural and artificial fibers.
- the following discussion covers all fibrous substrates consisting at least 50% glass fibers.
- Glass fibers are commonly produced by melting the glass raw materials and then fiberizing the molten liquid and applying a sizing chemical onto the filaments.
- the filaments so produced are cut to usable length.
- the fibers are typically deposited onto a moving, or sometimes stationary, support or collection surface to form a web of uniformly distributed fibers.
- the deposition of fibers may be performed by using any known method, such as, for instance, so-called air-laid, foam-laid or liquid-laid technologies.
- Liquid binder is applied on the fibers as they move along with the support or simultaneously with their spreading on the support.
- the glass fiber web is subsequently transported into an oven in which the binder is dried and set or cured. Normally this is the product, so-called carrier substrate, which the PVC flooring, or CV flooring manufacturers buy from the glass fiber felt producers.
- the properties of the fibrous products produced in this manner are mainly based upon the properties of the glass fibers, and the compositions of the sizing and binder chemistry. It would at times be beneficial to modify the products in order to enhance certain properties and/or reduce costs.
- a major problem encountered in the manufacture of the PVC floorings is the costs involved in the use of PVC paste. This is especially true with regard to the carrier substrate, where compact paste is used whereas in the thick layers foam paste is most often used.
- the carrier substrate is porous i.e. the interstices between the fibers are open all over the substrate
- the PVC paste when applied on one surface of the substrate, both saturates the entire substrate and tends to partially penetrate or permeate the substrate.
- This has been taken into account in prior art carrier substrates by adjusting the substrate thickness (means normally increasing the thickness of the substrate to exceed other requirements set for the thickness of the carrier layer) so that the substrate is able to absorb substantially all the PVC paste introduced thereon.
- the thicker is the carrier substrate, the slower the paste flows therethrough.
- the impregnation layer is the most expensive one, its thickness should be as low as possible.
- Another problem relates to the permeation of PVC paste through the carrier substrate, i.e. the flow of the paste through the substrate.
- the PVC paste collects onto the backing roller, from where it may be removed by doctor means, and returned back to use.
- part of the paste remains on the opposing surface of the substrate, and gets into contact with rolls following the paste application, whereby the roll surfaces get dirty.
- This can be avoided, for instance, by pre-gelling the paste with infrared lamps to dry the excess paste on the surface before the rolls.
- This kind of treatment may lead to uneven coating having variations in the thickness and surface quality of the coating.
- the penetration or permeation of the PVC paste is not a required feature, but proper and complete saturation of the substrate is normally the goal. Yet, the present technique does not know a way the complete saturation could be ensured without allowing some of the paste to penetrate or permeate the substrate.
- an object of the present invention is to provide an improved carrier substrate for the manufacture of PVC or CV flooring.
- the improvements include, for instance, • lowered material costs
- the present invention provides a method of manufacturing a carrier substrate for PVC flooring, a carrier substrate and PVC flooring utilizing said carrier substrate.
- the carrier substrate is basically manufactured in the manner described already above.
- the thus formed substrate is coated on one side thereof with a pigment paste, which acts as a kind of a barrier layer, too.
- the pigment coating makes the surface smooth, gives the surface a higher brightness, and prevents, at least for the most part the penetration or permeation of the PVC paste in the later manufacturing stages of the PVC flooring.
- the carrier substrate used in the present invention may be manufactured, for instance, by a so-called wet-laid process where the glass fiber web is manufactured in a comparable manner as paper is manufactured with a paper machine.
- Other applicable processes are the so-called foam laid or dry-laid processes.
- the fibrous suspension is introduced from a headbox onto a wire where the liquid from the suspension is removed through the wire by means of mere gravity draining or of specific suction boxes.
- the desired dryness binder in the form of a liquid is introduced into the web.
- the web saturated with the binder is taken to an oven to be dried and cured. This far the process is the same as a prior art method of manufacture, whereby the above should be taken as an exemplary option for the manufacture of the carrier substrate.
- the novel part of the process includes the coating of one of the faces of the dried and cured substrate with a pigment paste.
- the pigment paste is applied onto the web by means of conventional techniques such as; for example spraying, film transfer coating, roller coating, curtain coating, or the like. After coating with the pigment the web is again dried in drying means and rolled. The rolls, slit to desired dimensions, are then delivered directly to the customers who produce the PVC floorings.
- the coating pigment paste comprises at least one binder, either thermoplastic or thermoset, which is preferably a latex, like for instance, a polymeric latex binder, which is preferably composed of different acrylic esters or a co- or terpolymer of vinyl acetate, ethylene and/or acrylics, e.g. ethylvinyl acetate (EVA-latex) and styrene acrylic latex.
- the binder may also consist of a thermoset polymer, which is preferably a polycarboxy polymer.
- the polycarboxy polymer used in the binder may comprise an organic polymer or oligomer containing more than one pendant carboxy group.
- the polycarboxy polymer may be a homopolymer or copolymer prepared from a variety of well-known low molecular weight unsaturated polycarboxy I ates including e.g. acrylic- maleic and acrylic-methacrylic acids or unsaturated anhydrides or their combinations.
- the polycarboxy polymer may additionally comprise a copolymer of one or more of the aforementioned unsaturated carboxylic acids or anhydrides and one or more vinyl compounds. Methods for preparing these copolymers are well-known in the art.
- the curable aqueous binder composition may also contain a polyol containing at least two hydroxyl groups.
- the polyol can be industrially processed synthetic polyol such as triethanolamine, or from natural sources such as hydrolyzed fats and oils, reduced sugars and carbohydrates e.g. glycerine and mannitol.
- binders or derivates of such as polyvinyl alcohol (PVA), starch, styrene-butadiene rubber or combinations of different binders may be used.
- PVA polyvinyl alcohol
- starch starch
- styrene-butadiene rubber styrene-butadiene rubber
- combinations of different binders may be used.
- the binders may, in general, be either synthetic or of natural origin or a combination of both.
- the paste further contains mineral pigments, of which at least clay (normally bentonite or kaolin), calcium carbonate, titanium dioxide, gypsum, vermiculite, perlite, volcanic ash and talcum may be mentioned. Naturally, synthetic and coloured pigments are also applicable.
- the particle size of the filler material is usually about 5 ⁇ m or less.
- the pigment paste contains at least 30 weight percent, preferably 60 - 90 percent on dry basis, filler material.
- the paste may further contain cross-linkers, which are agents that are reactive with certain functional groups located primarily on the polymeric latex.
- Cross-linkers preferably are used in a concentration of 3 to 12 percent on a dry basis to improve important characteristics such as film formation, surface energy, wet strength etc.
- These reactive agents can be either organic or inorganic types, e.g. based on zirconium, urea/formaldehyde, melamine/formaldehyde or glyoxal derivatives.
- the use of the above-discussed coating paste makes it possible to use a thinner carrier substrate.
- the prior art glass fiber substrate having the basis weight of about 60 g/m 2 could be replaced with a glass fiber substrate having the basis weight of 35 g/m 2 provided with the pigment coating of the invention.
- the pigment coating of the present invention may be from 2 to 150 g/m 2 , preferably 2 - 50 g/m 2 .
- the basis weight of the coating may be raised even up to 150 - 200 g/m 2 .
- the back layer of a flooring product is formed of substantially thick PVC foam.
- the back layer may be left out and replaced with a pigment coating of the present invention coated on the back face of the substrate.
- the present invention makes it possible to use glass fiber substrates having a basis weight below 50 g/m 2 together with a coating having a basis weight from 2 to 50 g/m 2 .
- An advantageous feature concerning the coating of the invention is found after the impregnation of the coated glass fiber substrate.
- the pigment layer is smooth i.e. it hides the ends of the fibers, thereby giving a finished look to the product.
- the pigment coating does not form a totally closed surface, but such a barrier layer that prevents the free flow of PVC paste therethrough.
- the opening size in the pigment layer is smaller than the open cavities in the basic glass fibre substrate.
- the glass fiber material is substantially fine i.e. 8 to 15 microns, and the pigment coating is substantially thin
- both the glass fiber substrate, and the coating include small pores, which draw due to capillary action the impregnation paste.
- the impregnation paste not only impregnates the glass fiber layer, but also the coating layer whereby the structure of the substrate after impregnation is much more uniform than using the prior art techniques. Since the final impregnation of the paste takes place by capillary action, the impregnation paste does not enter to the open surface of the pigment layer but remains within the pores.
- the thinner coating layer is much more flexible that the thicker prior art layers, and its resistance to liquid penetration is superior to the prior art layers.
- the appended figure shows the carrier substrate of the invention used in a CV flooring.
- the CV flooring utilizing the carrier substrate of the present invention comprises in the mid part thereof the glass fiber carrier substrate 20a provided with the pigment coating 22 of the present invention.
- the actual production of the PVC flooring of this embodiment comprises several steps including a) Impregnating the glass fiber carrier substrate 20a with the impregnation paste 20b, preferably a PVC plastisol paste, b) Coating the substrate 20a with a second paste 24, on which the desired printing 26 is made. This is the so-called foam core. c) Laying the bottom layer 30 on the pigment coating 22 of the present invention. The bottom layer is most often so-called back foam, which gives the product the cushioning properties it requires, and d) Laying the top layer 28, which is a specially designed wear layer.
