1. Floor panel in the form of a multilayer, rectangular elastic laminate, comprising:
a main body including:
a core of elastic plastic which deforms,
a décor film on an upper side of the core,
a transparent finishing layer on the décor film,
a transparent lacquer layer, applied on the finishing layer,
an elastic back-pull layer on a back of the core, and
a lockable tongue and groove connection at least at two mutually opposite edges of the panel,
wherein:
the core comprises at least one core layer and a reinforcement layer,
the at least one core layer being made of a polyvinyl chloride (PVC) material,
the reinforcement layer being a glass fibre mat that is impregnated with a polyvinyl chloride (PVC) material,
the at least one core layer, the reinforcement layer, the Décor film, the transparent finishing layer and the back-pull layer being bonded to one another by calendering,
the décor film on the upper side of the core is made of a polyvinyl chloride (PVC) material which is printed with a décor,
the back-pull layer simultaneously acts as sound damping layer,
said back-pull layer including sound dampening fillers therein, said sound dampening fillers being a material different from said back-pull layer,
and the floor panel has a thickness of 4 to 8 mm.
2. The floor panel of claim 1 , wherein the core comprises one core layer, and the reinforcement layer is disposed at a bottom side of the core layer.
3. The floor panel of claim 1 , wherein the core comprises one core layer, and the reinforcement layer is disposed at a top side of the core layer.
4. The floor panel of claim 1 , wherein the core comprises an upper core layer and a lower core layer, and the reinforcement layer is disposed between the upper core layer and the lower core layer.
5. Floor panel in the form of a multilayer, rectangular elastic laminate, comprising:
a main body including:
a core of elastic plastic,
a décor film on an upper side of the core,
a transparent finishing layer on the décor film,
a transparent lacquer layer, applied on the finishing layer,
an elastic back-pull layer on a back of the core, and
wherein:
the core comprises at least one core layer and a reinforcement layer,
the at least one core layer being made of a polyvinyl chloride (PVC) material,
the reinforcement layer being a glass fibre mat that is impregnated with a polyvinyl chloride (PVC) material,
the at least one core layer and the reinforcement layer being bonded to one another by pressing,
the décor film on the upper side of the core is made of a polyvinyl chloride (PVC) material which is printed with a décor,
the back-pull layer simultaneously acts as a sound damping layer, said back-pull layer including sound dampening fillers therein, said sound dampening fillers being a material different from said back-pull layer, and
the floor panel has a thickness of 4 to 8 mm, and
a first groove that is disposed at a first longitudinal edge of the panel, the first groove being formed on top of a protrusion with a hook-like cross section extending from a lower portion of the first longitudinal edge of the panel,
a first tongue that is disposed at a second longitudinal edge of the panel opposite to the first longitudinal edge, the first tongue being formed at a bottom of a protrusion extending from an upper portion of the second longitudinal edge of the panel,
the first tongue having a cross section that is complementary to the first groove to be received by the first groove,
a second groove that is disposed at a first traverse edge of the panel extending perpendicular to the first and second longitudinal edges, the first groove being formed on top of a protrusion with a hook-like cross section extending from a lower portion of the first traverse edge of the panel, and
a second tongue that is disposed at a second traverse edge of the panel opposite to the first traverse edge, the second tongue being formed at a bottom of a protrusion extending from an upper portion of the second traverse edge of the panel,
the second tongue being provided to be pressed into the second groove in a downward direction perpendicular to a surface plane of the panel,
the second tongue and the second groove being elastically deformable to be deformed during pressing the second tongue into the second groove.
6. Method for manufacturing a floor panel in the form of a multilayer, rectangular elastic laminate, comprising the following steps:
a) extruding at least one core layer of a polyvinyl chloride (PVC) material,
b) extruding a décor film of a polyvinyl chloride (PVC) material,
c) extruding a transparent finishing layer of a polyvinyl chloride (PVC) material,
d) extruding a back-pull layer of a polyvinyl chloride (PVC) material including sound dampening fillers therein, said sound dampening fillers being a material different from said back-pull layer,
e) printing the décor film with a décor,
f) providing a glass fibre mat and impregnating this glass fibre mat with a polyvinyl chloride (PVC) material to form a reinforcement layer,
g) applying the reinforcement layer to the at least one core layer to form a core, laminating the décor film and the transparent finishing layer onto a top side of the core and applying the back-pull layer at the a bottom side of the core to form a laminate,
h) bonding the core, the décor film, the transparent finishing layer and the back-pull layer of the laminate resulting from step g) to one another by calendering,
i) imprinting a haptic structure onto a surface of the transparent finishing layer by rolling, and
j) applying a transparent lacquer layer on the transparent finishing layer.
7. Method of claim 6 , wherein step g) comprises the step of forming of the core by applying the reinforcement layer to a bottom side of a core layer.
8. Method of claim 6 , wherein step g) comprises the step of forming of the core by applying the reinforcement layer to a top side of a core layer.
9. Method of claim 6 , wherein step a) comprises the step of extruding two core layers, and step g) comprises the step of forming of the core by sandwiching the reinforcement layer between these two core layers.
