Definitions

the present invention relates to the production of latex, PVC and plasticizer-free floor and wall coverings with chemically foamed and optionally structured foam layers
Textile floor and wall coverings with a back-foamed layer made of a natural or synthetic latex and PVC plastic coverings are used today on a large scale due to their diverse decorative possibilities through simple installation and value for money.
the possibility of equipping the coverings with soft, foamed backs, which contributes significantly to the insulation of the impact sound and improves walking comfort, has ensured the further spread of such materials.
the foaming enables the generation of surface structures either by foaming in appropriate forms or embossing rollers or by partial chemical activation or inhibition of foam formation.
technically only mechanical foaming is carried out by injecting air into the latex mass, since chemical foaming requires high temperatures which damage the textile pile.
floor coverings in particular are usually produced today in endless webs with a width of up to 4 or 5 m, which extremely limits the possibilities both in terms of the material and the processing techniques.
Textile floor coverings are either manufactured using the tufting process or from needle punched nonwovens, which are fixed on the back with a styrene-butadiene or other latex material and then coated with a mechanically foamed synthetic or natural latex layer and fixed by drying.
the textile layer consists mainly of polyamide, polypropylene or polyester fibers, which can no longer be separated from the latex layers, so that such composite layers are not recyclable.
plastic floor coverings have usually been produced from latex dispersions or PVC plastisols in a coating process on a fabric or release paper base and then hardened.
the plastisols consist of PVC particles, plasticizers, and usual auxiliary substances as well as fillers, which sinter together into a matrix when dried in the warmth.
the layer can also be thermally foamed, and additional structuring can be achieved by applying blowing agent activators or deactivators to certain areas.
blowing agent activators or deactivators it is also possible to vary the properties to a very large extent by applying several layers of different composition.
PA and PES are ideal materials for textile coverings and PVC in terms of their cost-effectiveness and properties, the ecological aspects that are to be taken into account more and more are required - recyclability of the products, avoidance of solvents and halogen-containing components - to look for processes for the production of coverings, which are latex, PVC and plasticizer free. For economic and technical reasons, however, it is necessary to maintain the previous manufacturing widths and, if possible, the existing manufacturing devices. Furthermore, the floor covering should also consist of different layers, one or more of which is chemically foamed and if necessary. are partially structured by activating or deactivating the foaming process.
This process currently allows foams with densities between 30 and 175 kg / m3 and thicknesses between 5 and 15 mm to be produced.
the width of these foams is, however, limited to about 2 m, since it is not possible to produce wide-slit nozzles of a larger size. It is not possible to produce conventional floor coverings economically using this method.
plasticizer-free polyurethane foams by mechanically foaming the components while injecting air, but the foaming cannot be chemically prevented and no structure can be created as a result.
the mixtures according to the invention can be distributed uniformly over widths of 4-5 m using commercially available powder spreading machines, so that a homogeneous, uniformly thick foam layer is produced when they are subsequently passed through the drying oven.
Multiple layers can also be produced in a simple manner by sprinkling a second powder layer on a first solidified and, if necessary, leveled layer, again drying or gelling.
the layer can be colored by temporarily printing on the color pattern, and structuring by printing on an activator or deactivator.
the polymers which can be processed according to the invention comprise a large number of thermoplastic products.
the most important parameter is the melt index (MFI 190 ° C / 2.16). It was found that with melt indices below 2.5 and above 40, the too high or too low melt viscosity no longer permits a good cellular structure of the foam. A melt index of around 10 - 20 seems to give optimal results.
the crystallite melting point of the polymers should be below the decomposition range of the blowing agent mixture, but not so low that the foam begins to flow, for example, under strong sunlight or weight. Crystallite melting points in a range of 70 - 110 ° seem to be well suited.
Suitable polymers are copolymers of ethylene and vinyl acetate, polyethylene, polypropylene, copolymers with polyvinyl acetate, polymethyl methacrylate, polyethylene acrylic acid ester copolymers, polyethylene acrylic acid esters, maleic anhydride copolymers and others.
the polymers are ground from the commercially available granules to a maximum particle size of 400-600 ⁇ m, preferably 10-400 ⁇ m, and mixed in this form with the other components.
additives that are also used in the usual foam mixtures are possible as additives.
examples include inorganic fillers such as chalk, silicates, magnesium or aluminum hydroxides, heavy spar, silica, glass powder, carbon black, titanium dioxide or other color pigments that simultaneously change the translucency of the foam.
Wood or cork flour or also temperature-resistant plastics such as polyurethanes are particularly suitable as organic additives. These are mixed into the mixture as fine powders with grain sizes from 10 to about 500 ⁇ m, the fillers being added to the mixture in amounts of 5-50%, depending on the product.
blowing agent for the foam layers the usual products such as azodicarbonamide, oxibis-benzenesulfohydrazite, azoisobutyric acid dinitrile, toluenesulfohydrazite and others are used as a preferred blowing agent can be reduced to temperatures of 120 °.
the foaming temperature can be in this way to the respective Adjust foaming plastic and its viscosity well.
the blowing agents are added as fine powder (2 to 12 ⁇ grain size) or as a batch (rubbed with paraffin or antistatic) in amounts of 0.5 - 10% to the mixture.
the substances known for such foam mixtures can be used as deactivators for the points at which foaming is not desired. Trimelitic anhydride, benzotriazole or thiourea are preferably used.
the deactivator In contrast to the solvent-containing pastes, which enable the deactivators to diffuse into the foamable layer, the deactivator must be printed on together with a means of transport in the agents according to the invention. Suitable means of transport are e.g. liquid paraffins or liquid antistatic agents or crosslinkable derivatives of methacrylic acid.
the deactivators should be used in an amount of approx. 0.5 - 2% based on the mass of the foam layer to be structured.
peroxides can be added to the mixture to crosslink the foam and to improve the temperature resistance of the polymers, both during processing and during later use.
Bactericides, antistatic agents, antioxidants, etc., as are customary in latex and plastic processing, are also suitable as auxiliary substances.
the preliminary product is a common tufting covering without backing, needle felt covering, only with fiber impregnation or a heterogeneous, foam-structured elastic floor covering, which are pre-produced on the appropriate production machines.
a powder scattering machine available on the market is used as additional equipment; the overall system is shown schematically in FIG. 1.
the carrier material, textile covering or prefabricated heterogeneous elastic covering is fed continuously to the system by means of a roll (1) and storage metering.
a so-called fixing or base coat for closing the substrate surface is applied by means of a coating device (not shown) and, if necessary, heated by heating (air circulation duct or radiator) and smoothed using a smoothing device (3).
Example 1 In the second application unit (4), the EVA dry blend described in Example 1 is applied using a powder spreader and then melted in an infrared emitter station (5), but not yet chemically foamed or crosslinked.
the melted foam surface can also be smoothed and solidified using a smoothing drum (6).
the fabric thus obtained is heated in a drying / gelling oven (7) to approximately 120-200 ° C, causing the EVA powder to foam and crosslinked by reaction of the peroxides.
a smoothing unit (3), a cooling section (8) and a storage unit and reel (9) are in turn connected downstream. If necessary, the necessary finished goods inspection of the floor covering web can be carried out directly continuously in the plant. Then it is cut to length and rolled on individual rolls before the material goes to the finished goods warehouse.
the heterogeneous elastic floor covering containing EVA foam layers can be produced on a conventional coating system suitable for PVC floor coverings. Powder spreaders available on the market are used as additional equipment.
the device used is shown schematically in FIG. 2.
the carrier material textile, glass and similar fabrics
the carrier material is continuously fed into the system by means of unwinding (1) and storage metering.
the corresponding coating material for closing and smoothing the carrier substrate is applied by means of a coating device (not shown) as a so-called fixing or base coat, heated by means of radiators (5) and smoothed using a smoothing device (3).
the EVA dry blend described in Example 2 or 3 is applied using a powder spreader and then melted in an infrared emitter station (5), but not yet chemically foamed or crosslinked.
the melted foam surface can also be smoothed and solidified using a smoothing drum (6).
a multicolored print design is applied to the smooth foam surface obtained using a printing machine (7) using polymer binder printing ink.
the printing layer is covered by a transparent coating compound.
the fabric thus obtained is in heated to 160-200 ° C in a drying / gelling oven, which causes the EVA dry blend layer to foam - only partially when structured - and is crosslinked by the peroxides.
the transparent cover layer dries and reacts simultaneously.
a foamable EVA dry blend can be applied in a further powder spreading machine (4), as described above, which then melted in accordance with (5), (3), (9) , solidified, smoothed and foamed.
a final surface treatment using a smoothing unit (3) serves to homogenize the foam surface.
a structured roller in the manner of an embossing mill can also be used here.
the material web is cooled in the cooling section (10) and then removed from a storage device and reel (11) of the system. If necessary, an intermediate inspection with ready-made single rolls can be carried out, which are then fed directly to the finished goods warehouse.
the above-described covering can also be produced in a batch process, in that lengths of approximately 500 m are rolled up after each of one or more of the above steps, stored temporarily and fed to the next processing station at a later point in time.
