Plastic floor covering and method for obtaining same
A floor covering produced by coating and including a thermoplastic-based structure, in particular plasticized PVC, reinforced with a textile reinforcement, optionally combined with a foam backing. The visible surface consists of a surface coating providing decoration and wear resistance to the product. The back surface, designed to be in contact with the floor, consists of a textile web, the bonding between the textile structure and the supporting back surface being produced by means of an additional plastisol layer, which penetrates over a minor part of the thickness of the textile structure and which, after gelling, bonds the textile to the thermoplastic substrate back surface.
1. A floor covering produced using coating techniques, said floor covering comprising:
a fiberglass mat;
a thermoplastic base structure impregnating said fiberglass mat;
a surface layer provided on an upper surface of said impregnated fiberglass mat providing coloring, decoration, and resistance to wear;
a plastisol layer adhered to a lower surface of said impregnated fiberglass mat; and
a non-woven polyester textile web adhered to said plastisol layer, said textile web having a thickness between 0.5 and 5.0 millimeters, having an elongation capacity between 30 and 120 percent, and having a weight per square meter between 80 and 300 grams, said plastisol layer penetrating said textile web a distance between 0.5 and 15 percent of the thickness of said textile web;
wherein said textile web defines a lowermost surface of said floor covering.
2. A floor covering as claimed in claim 1 , wherein said thermoplastic base structure comprises plasticized polyvinyl chloride (PVC).
3. A floor covering as claimed in claim 1 , further comprising a foam underlay provided between said lower surface of said impregnated fiberglass mat and said plastisol layer.
4. A floor covering as claimed in claim 3 , wherein said foam underlay is formed using a plastisol chemical foam.
5. A floor covering as claimed in claim 3 , wherein an acoustic insulation characteristic is about 19 dB, a thermal insulation characteristic is 15° C., and a comfort when walking characteristic according to NFP 90-104 and NFP 90-203 and evaluated by the level of softness as measured by a depth of a foot sinking into said floor covering, is about 1.3 mm.
6. A floor covering as claimed in claim 1 , wherein said plastisol layer smooths said impregnated fiberglass mat.
7. A floor covering as claimed in claim 1 , wherein said surface layer comprises embossed patterns obtained by a localized expansion of a layer of foam inserted between said upper surface of said impregnated fiberglass mat and said surface layer.
8. A floor covering as claimed in claim 1 , wherein an acoustic insulation characteristic is 16 dB, a thermal insulation characteristic is 10° C. and a comfort when walking characteristic according to NFP 90-104 and NFP 90-203 and evaluated by the level of softness as measured by a depth of a foot sinking into said floor covering, is about 1.15 mm.
