Definitions

• the invention relates to a floor covering insulating substrate with a slip-resistant surface design according to the preamble of claim 1.
• the underlay under such a covering covering an additional task in addition to the actual insulating effect, namely a stabilizing function with respect to vertical and horizontal forces introduced into these floor coverings.
• the corresponding insulation underlays should be designed to be more resistant to pressure than would be required, for example, for floor coverings such as parquet and laminate in order to prevent vertical weight loads from leading to vertical deformations.
• Another disadvantage is that once laid on this sticky insulation pad flooring segment is difficult to correct in position without causing damage to the insulation pad. Also, unwanted side effects when walking on the floor or even when depositing objects on the flooring caused by the change of adhesion and again detachment of the floor covering of the insulation pad.
• the inventive solution provides that a special surface coating (coating) is applied directly to the insulating substrate, which usually consists of a foamed plastic, or alternatively a film with this special surface coating is laminated onto the insulating substrate.
• the central inventive feature of this specially applied surface coating is that it increases the Gleitreibbeiwert or Gleitreibiere ⁇ of the insulating backing surface to a value greater than 0.5. However, this is achieved without the surface exerting an adhesive effect, as far as a connection between the flooring segments and the insulating substrate in the vertical direction.
• the increase of the coefficient of friction ⁇ is hereby set so that the floor covering laid on the insulating substrate is secured against vertical movement on the insulating substrate, but at the same time a displaceability which is possible to a limited extent during the laying process of the individual flooring segments is still ensured. It is also ensured by the lack of tackiness of this surface coating that a slight lifting of the flooring segments of the insulation pad at any time of laying is possible and so corrections when laying the flooring segments can be made at any time.
• the inventive surface design of the novel insulation backing causes the topsoil can set up over the insulation pad by its appropriate extent, but this does not adhere to the insulation backing and thus can change its position to the insulation pad. That is, the topsoil can make a slip at the corresponding extent and the subsequent contraction with respect to its position to the insulation pad, this being known under the technical term "stick-slip". This is not possible with a bonding of the insulating substrate and represents a further advantageous aspect of the invention.
• the increase of the Gleitreibbeiwerts or Gleitreibiere ⁇ the surface of the insulation pads to a value greater than 0.5 can be effected in this case by means of two different surface designs.
• the first approach provides for a coextruded polyurethane coating which has a rough or uneven surface. These surface properties arise on the one hand from the basic properties of the polyurethane used on the other hand, but also by the manufacturing process, for example by the cooling process in the production of the coextruded polyurethane coating.
• the second solution also provides a surface finish, which in this case consists of an extruded polyethylene coating. It is a mixture of an elastomer and a polymer, with the addition of an additive that prevents blocking of this material so that it is not tacky.
• the result of the combination of these materials is a polyethylene coating, which, although having the desired blunt surface and thereby has a higher Gleitreibiere or a higher Gleitreibbeiives ⁇ , but is not tacky at the same time by the addition to prevent blocking.
• these coatings are either applied directly to the surface of an insulating material during its production or produced as a separate film, which is then laminated as a slip-resistant surface on the insulation underlay used. This results in the advantage that this form of insulation backing without further preparation, for example by removing a cover sheet is used.
