Floor lining insulation underlay with a slip-inhibiting surface configuration

Abstract

A floor lining insulation underlay with a slip-inhibiting surface configuration used for floor linings which are produced in large-area form from individual floor lining segments. The floor lining insulation underlay comprising a special surface coating applied to the surface of the insulation underlay. The sliding friction coefficient μ of the surface coating is increased in relation to the actual surface of an insulation material of the insulation underlay to a value greater than 0.5.

1 . A floor lining insulation underlay with a slip-inhibiting surface configuration used for floor linings which are produced in large-area form from individual floor lining segments, the floor lining insulation underlay comprising a special surface coating applied to the surface of the insulation underlay, the sliding friction coefficient μ of which surface coating is increased in relation to the actual surface of an insulation material of the insulation underlay to a value greater than 0.5. 
     
     
         2 . The floor lining insulation underlay with a slip-inhibiting surface configuration as claimed in  claim 1 , wherein the surface coating is in the form of a co-extruded polyurethane coating which has a rough or uneven surface for the purpose of increasing the sliding friction coefficient μ. 
     
     
         3 . The floor lining insulation underlay with a slip-inhibiting surface configuration as claimed in  claim 2 , wherein the rough or uneven surface characteristics arise from an interaction of the material basic characteristics of the polyurethane that is used with the manufacturing process of the cooling process during the production of the co-extruded polyurethane coating. 
     
     
         4 . The floor lining insulation underlay with a slip-inhibiting surface configuration as claimed in  claim 2 , wherein the increase of the sliding friction coefficient of the surface coating is determined from the surface unevennesses and from the elasticity of said surface. 
     
     
         5 . The floor lining insulation underlay with a slip-inhibiting surface configuration as claimed in  claim 1 , wherein the surface coating is in the form of an extruded polyethylene coating which has a dull surface and which thus has a relatively high sliding friction coefficient μ. 
     
     
         6 . The floor lining insulation underlay with a slip-inhibiting surface configuration as claimed in  claim 5 , wherein the extruded polyethylene coating is composed at least of a mixture of an elastomer and a polymer and of a further material additive which prevents an adhesive action of the material by counteracting a blocking of said material. 
     
     
         7 . The floor lining insulation underlay with a slip-inhibiting surface configuration as claimed in  claim 1 , the surface coating being either applied directly to the surface of the insulation material during the production thereof or being produced as a separate foil which is then laminated as a slip-inhibiting surface onto the insulation underlay. 
     
     
         8 . The underlay as claimed in  claim 1 , wherein the special surface coating is applied to an upper surface of the insulation underlay. 
     
     
         9 . The underlay as claimed in  claim 1 , wherein the special surface coating is applied to a surface of the insulation underlay facing a floor lining.
