Abstract
A panel has an upper side facing the room in the use position and a lower side facing the floor. The lower side is coated, at least in sections, with a bonding layer composed of polymer. The bonding layer has an uneven surface on the outer side facing away from the panel, and has been coated at least in sections with a damping layer composed of polymer. A covering composed of panels, a process and an apparatus for producing the panels are also described.
Claims38
A panel comprising an upper side facing a room in a use position and a lower side facing a floor, the lower side having a bonding layer at least in sections, the bonding layer having a density of more than 600 kg/m3 and an uneven surface on an outer side facing away from the panel, and the bonding layer having been coated with a damping layer composed of a soft, plastically deformable polymer, the bonding layer being formed from at least one of a material of the panel and a non-adhesive, hard polymer, the uneven surface of the bonding layer comprising projections adapted to convert a vertical deflection of the panel into a horizontal motion of the projections with the projections being embedded in the damping layer of said soft, plastically deformable polymer.
A covering comprising a plurality of panels which are bonded to one another in a floating manner and are arranged on a fixed substrate with a sound-reducing layer on a lower side of the panels, and the sound-reducing layer comprising at least one bonding layer with a density of more than 600 kg/m3 and an uneven surface which has been coated at least in sections with a damping layer composed of polymer and which has projections designed to convert a vertical deflection of a respective one of said panels into a horizontal motion of the projections.
A sound-reducing coating comprising a bonding layer composed of a non-adhesive hard polymer provided with projections on one side, said bonding layer having a density of more than 600 kg/m3 and the projections being embedded into a damping layer composed of a soft plastically deformable polymer and being designed to convert a vertical deflection of a panel into a horizontal motion of the projections.
A panel comprising an upper side facing a room in the use position and a lower side facing a floor, the lower side having a bonding layer at least in sections, the bonding layer having a density of more than 600 kg/m3 and an uneven surface on an outer side facing away from the panel, the bonding layer having been applied at a manufacture stage, the bonding layer being formed from a material selected from the group consisting of a material of the panel and a non-adhesive, hard polymer, and the bonding layer, in a use position, having been coated at least in sections with a damping layer composed of a soft, plastically deformable polymer, and the uneven surface comprising projections adapted to convert a vertical deflection of the panel into a horizontal motion of the projections.
A covering comprising a plurality of panels which are bonded to one another in a floating manner, are arranged on a fixed substrate, and have a sound-reducing layer on a lower side of the panels, the sound-reducing layer having at least one bonding layer having a density of more than 600 kg/m3 and an uneven surface which has been applied at a manufacture stage and has been coated, in a use position, at least in sections with a damping layer composed of a soft, plastically deformable polymer and the bonding layer being formed from a material selected from a group consisting of a material of the panel and a non-adhesive, hard polymer, and said uneven surface comprising projections adapted to convert a vertical deflection of one of said panels into a horizontal motion of the projections.
