Embodiment

[0142] This example describes the manufacture and properties of a possible covering according to the invention. The manufacturing recipes (expressed in % by weight) for the various layers included in order to make a possible cover of this example are assembled in the table below.

[0143]

[0144] a anti-wear layer; b decorative layer; c basal layer; d Foamed backing layer; e coating; f K value; g Fast melting plasticizers known to those skilled in the art.

[0145] A nonwoven fiberglass membrane 0.3 mm thick and weighing 35 gsm was coated with 425 gsm of filled PVC emulsion corresponding to formulation "SU" in the table. The glass fiber membrane thus impregnated was then placed on a drum heated to 155° C., resulting in a base layer having a thickness of 0.35 mm.

[0146] Subsequently, the top side of the base layer was coated with 250 gsm of PVC plastisol corresponding to formulation "DL" in the table. The coated structure was then heated at 155°C on top of a gell...

Abstract

The current invention concerns a covering, such as a floor covering, wall covering or ceiling covering, said covering comprising a surface layer, and a substrate layer attached to said surface layer, said substrate layer optionally comprising one or more reinforced thermoplastic layers. Said covering further comprises a backing layer on the bottom side of said substrate layer, opposite to said surface layer, and a textile layer attached to the bottom side of said backing layer, optionally through a contact layer. The covering further comprises a coating applied to the bottom of said textile layer. The invention also provides a method for producing a covering, such as a floor covering, wall covering or ceiling covering.

Description

technical field [0001] The present invention relates to the technical field of surface coverings, such as coverings for floors, walls or ceilings. Background technique [0002] Flexible plastic surface coverings have been manufactured for a long time. Surface coverings of this type are suitable for covering surfaces such as floors, walls or ceilings in the interior of buildings such as offices, hospitals or homes. A flexible plastic surface covering may be applied to a surface by placing an adhesive underneath the surface covering. Coverings of this type are typically composite products comprising various layers. Flexible plastic surface coverings typically include a base layer of thermoplastic material, often reinforced with a fabric material embedded in a body of the thermoplastic material. Also, to improve comfort levels and provide insulating and flexible qualities to the cover, the reverse side of the cover may be combined with a foamed backing. Furthermore, the upp...
