Problems solved by technology

The known floor covering has the disadvantage that it is difficult to cut because of the very hard particulate material (corundum problem).
This results in problems during the preparation and compounding and / or during further processing of the floor covering.

example 1

[0029] A polypropylene powder having an average particle size of 300 μm was sprinkled in a quantity of 275 cm3 per cm2 on a sheet of base material of a sulfur-crosslinkable SBR mixture. The maximum of the melting peak of the polypropylene powder, which was determined by DSC analysis according to DIN 53765, was at 163° C. Subsequently, the powder-sprinkled sheet was subjected for a period of 5 minutes to a vulcanization process at 180° C. in a continuous vulcanization system containing a belt press. The result was an elastomeric floor covering which, in a slip test performed using a British pendulum tester (BPT) and using water as the lubricant, achieved a slip resistance value of 40 scale divisions.

example 2

[0030] A sulfur-crosslinkable SBR mixture was mixed with 40 vol. percent of the aforementioned powder at a dump temperature of 120° C. This material was calandered into a raw sheet, which was then split in the middle. The resulting raw sheet was subjected for a period of 7 minutes to a vulcanization process at 180° C. in a non-continuous vulcanization system. In a test carried out as described above, using water as the lubricant, the resulting elastomeric floor covering achieved a slip resistance value of 36 scale divisions.

example 3

[0031] In another embodiment, the polypropylene powder-containing mixture described in Example 2 was calendered into a sheet. This sheet was additionally sprinkled with 275 cm3 / cm2 of the same polypropylene powder. Then, the sheet was subjected for a period of 5 minutes to a vulcanization process at 180° C. in a continuous vulcanization system containing a belt press. The result was an elastomeric floor covering which, in a slip test performed as described above and using water as the lubricant, achieved a slip resistance value of 40 scale divisions.

Abstract

A floor covering is provided having a high slip resistance and including a base material which is substantially in sheet or tile form and is made of an elastomeric material and which has a slip-resistant surface containing granular particles. In order to provide ease of manufacture and processing of the floor covering, the granular particles are composed of a polymeric material having a hardness significantly greater than that of the elastomeric material.

Description

[0001] This application claims priority to German Patent Application DE 102006034646.7-25, filed Jul. 24, 2006, and hereby incorporated by reference herein. BACKGROUND [0002] The present invention relates to a floor covering having a high slip resistance and including a base material which is substantially in sheet or tile form and is made of an elastomeric material and which has a slip-resistant surface containing granular particles. [0003] A floor covering of this type is known from International Patent No. WO 03 / 100162. The floor covering described therein includes a support made of a plastic material, preferably a thermoplastic polymer or a thermoplastic elastomer. To provide enhanced slip resistance, the surface of the support is roughened by granular particles. Such granular particles preferably include hard particles of quartz, silicon carbide, aluminum oxide and / or emery. [0004] The known floor covering has the disadvantage that it is difficult to cut because of the very har...
