Process for the production of foot "floor covering with non-slip back cover

It is known that carpet, PVC, linoleum and cork "S ¹ USS floor coverings can be coated on the back". and impact sound insulation 6 -Ks are countless methods that deal with the finishing of the back of floor coverings »

About the properties of the top layer of a floor covering as long as possible, as well as the insulating properties to increase and improve the entire floor covering, the back is provided with insulating and insulating materials, both organic and inorganic Can be of origin «To improve the sound, heat, cold and impact sound insulation properties of the floor covering one generally used jute felt, jute felt fleece,

Jutefilzgewebe, wool felt, Wollfilzvlies, Wollfilzgewebe, Wollfilzpappe preimpregnated Wollfilzpappe fully impregnated Wollfilzpappe, coconut fabric, wood wool, glass wool, asbestos fiber ,, rock wool, Bitumenkorkfilz, cork sheets, Korkfilz, Korkment etc _0, either in "their natural state or strength-improving with different and / or are equipped with water-repellent materials ₀

The joining of these different materials, namely the floor covering layer with the floor covering underside, can be done once mechanically, as in Z ₉ B ₀ by needling, and the other time with the help of chemical auxiliaries, in particular with the help of adhesives based on glue, starch, Urea-i'ormaldehyde synthetic resin base or based on various plastic dispersions, such as polyvinyl acetate, polyvinyl propionate, polyacrylic acid esters and others, which can be used either as homopolymers with or without external plasticization or heteropolymers with internal and / or external plasticization.

Procedures are particularly often used in which the back Coating of carpets with the help of rubber latex is carried out. It can be natural rubber latex and / or synthetic rubber clatioes or trade their mixtures. Especially when producing Knobbed carpets and tufted carpets are finished on the reverse used on the basis of Kautsehuklaticee.

Regardless of the equipment used on the back of the floor covering After the traditional process, it is common to lay the flooring through Make gluing to avoid Eutsohgefahr. Bumps, To avoid waves and rolling up in the floor covering,

In order to save the annoying, uneconomical and disadvantageous gluing when laying floor coverings, many efforts were made to equip the back of the floor covering in such a way that it can be laid immediately, efficiently and quickly. Gluing the Pussbodenbeläge can also be performed by less qualified staff _o

Numerous proposals are concerned with the resolution of this issue ₀ the one hand, is it, for example, to carpeting materials ,, which are to avert the risk of slipping as juteartige impregnated with rubber latex sheeting, various grid-like GewebearteBi that have been prepared with schwachklebrigen plastics to both sides to reach an adhesive surface, or sheets based on polyvinyl chloride foam or iOlyurethanschaumbahnen _e On the other hand, there are coverings with a waffled rubber or »rubber covering reverse side as well as floor coverings. Made of felt and the surface of which has also been prepared with plastic that gives rubber latex adhesion «

It is also known that the back of the floor covering is covered with self-adhesive to provide ·, The advantage of such a procedure compared to conventional pussbodenverkleben with the help of liquid glue is the one that the puss floor coverings without Odor nuisance caused by glue and can be installed professionally by anyone without additional equipment, provided that that the subfloor has no major bumps, stress cracks or settlement cracks, completely dry, not porous or rough and is not contaminated with oil, wax, varnish or paint residues.

This method also has the advantage that the covering is relatively effortless in the event of any installation errors can be pulled off again, realigned and laid again, which can be done with the above-mentioned liquid tfussbodenverkleben is not possible due to the tightening of the adhesive, but there is also the disadvantage that the with The back of the floor covering provided with self-adhesive must be provided with a release agent, usually siliconized paper, must be provided, otherwise this self-adhesive will be on the top when stacking, rolling up, transporting or storing of the floor covering sticks, so that not only the surface is soiled, but also the adhesive strength is lost, quite apart from the fact that the covering does so when the self-adhesive backs touch each other firmly glued so that separation is not possible without damaging the covering «This results in the difficulty because the said protective layer has to be peeled off by hand and so - by touching the self-adhesive Back of the floor covering - heavy soiling of the hands results in soiling of the floor coverings practically difficult to avoid. However, this must be absolutely prevented, especially in the case of carpets. since stains can often no longer be removed without a trace,

Another disadvantage is that this adhesive has practically no insulation against heat, cold, sound or impact sound Brings properties with it, so that only laying by self-adhesive as such is an improvement, whereas but the application of the rear side covering layer - around the useful life expectancy, sound, cold, heat and to increase footfall soundproofing properties - still like must be made separately before.

It has now been found, surprisingly, that with the help of a permanently plastic covering compound consisting of thermoplastics, Fillers, plasticizers and pigments with adhesive surfaces and sound, cold, heat and impact sound insulating and insulating properties, previously unknown and completely new floor coverings with excellent behavior can be reached. The new, inventive, non-slip, Permanently plastic covering compound for the back of the floor covering increases the service life in the temperature range of the application of the floor covering, is waterproof, water-repellent, rot-proof, moth and insect proof "

Based on the fact that the covering is a permanently plastic compound, the covering edges close after laying each other completely and merge seamlessly into one another due to the later tread load «, smaller ones, through crooked ones Walls, skirting boards and the like. Joints can also be created by slightly stretching the locking point be invisibly balanced ",

Since then, according to DIN 18 «365, the sub-floor had to be laid before laying for suitability for the application of a prescribed carpet must be thoroughly prepared, which is costly and time-consuming. Requirement for laying a Carpet flooring required condition of the subfloor: no major unevenness of the subfloor; no stress and settlement cracks in the substrate j sufficiently dry and firm substrate; not a porous one or rough ground! larger areas were before first to scrape out, level and grind} impurities of the subsurface, ζ · Β · through dirt, oil, Wax, varnish or paint residues had to be removed carefully!

incorrect altitude of over surface of the substrate in relation to the height of subsequent building components had to be balanced and the like _o

With the new type of floor covering, the back of the running layer of which is provided with the new, non-slip, permanently plastic covering compound according to the invention, even tfloors can be laid without prior preparation, i.e. completely regardless of whether the subfloor is uneven, blistered, cracked, damp, porous, with oil , wax, polish or i ^<l arbresten dirty, rough, dusty or grainy, extreme unevenness in the substrate can be compensated.

The new floor covering with the flooring compound according to the invention provided., can be applied directly to concrete, stone and tile floors, anhydrite mortar screed, Cement mortar screed, magnesia mortar screed, gypsum mortar screed, stone wood mortar screed and plastic filler floors, further on wooden floorboards, on cast iron, cork stone, foam boards and on PVC, linoleum and aluminum cardboard floors etc. are relocated.

These new puss floor coverings can be used both in lengths as well as in plates or blown. It is particularly advantageous that when laying of the floor covering in the same color, there is practically no waste, as the new, permanently plastic Even the smallest residues can be used on the back of the covering, which can be fitted seamlessly.

The other advantage of using this novel Jj'ussbodenbelags, the back surface of which with the new, inventive, non-slip, permanently plastic Btlagamaese is equipped, inform of tiles or

The novel features according to the invention of the Pussbodenbelages be achieved in that one can use on the back of the running layer a permanently plastic lining material made of thermoplastics, fillers, plasticizers, color pigments "other additives attaches ₆ The ratio of each component is selected such _t that the end result is a permanently plastic mass without rubber elasticity or «. Is rebound properties. The lining material must not be plastic only in the processing and mounting to the back of the running surface of the flooring of floors and amorphous, but also in the temperature range of the application, d _e h _o at room temperature, permanently plastic and amorphous properties possess "When thermoplastic used in applications: polyacetal, Polyisobutylene, polybutylene, polypropylene, polyethylene, polystyrene _t polyacrylonitrile, polyacrylic ester, polymethacrylic ester, polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, polyvinyl acetate iulj / υ liiji lau β Lu. ί, polyvinyl ether, polytetrafluoroethylene, polytrifluorochloroethylene, polyamides, coumarone indene resins, natural resins, bitumen and others.

The thermoplastics are melted and mixed with plasticizers. sets, mixed homogeneously with fillers, pigments and - if necessary other additives * This is done in a well-known way in stirrers, mixers, kneaders, etc. The application of this covering mass to the back the running layer e.g. by extrusion, painting, calendering etc. are not difficult and can be done in any way.

The application of the covering compound to the back of the floor covering takes place in the molten state at an elevated temperature. When using this procedure for carpeting, especially if it is a polyamide and / or polypropylene needle felt or needle pile The result is a textile floor covering in which the man-made fibers are firmly anchored and welded into the plastic mass are attached, which creates a previously unknown strength of ü'ussbodenbelags. The covering compound should be applied to the back of the running layer in such a way that there is a closed surface forms, which closes the entire back.
