Definitions

  • Rubber floor mats have emerged as the floor mat of choice in most industrial applications due to their durability, weather resistance, flexibility, abrasion resistance, skid (slip) resistance, reasonable cost, and ease of manufacture.
  • cross-linking agents include, but are not limited to, tetramethyl thiuram tetrasulfide, selenium diethyl dithiocarbamate, tetramethyl thiuram disulfide, and tetraethyl thiuram tetrasulfide.
  • the amount of cross-linking agent may vary as desired by one of ordinary skill in the art. Desirably, the cross-lmking agent is added to the base layer composition in an amount ranging from about zero to 5 parts per weight of cross-linking agent per 100 parts per weight of elastomeric /thermoplastic material. More desirably, the cross-lmking agent is added to the base layer composition in an amount ranging from about 1 to 2 parts per weight of cross-lmking agent per 100 parts per weight of elastomeric /thermoplastic material.
  • the present invention is also directed to methods of making the above-described mat.
  • the base layer sheet and cap layer sheet may be formed from separate processes, such as a calendering process, and subsequently joined, prior to curing, to form a composite sheet.
  • the base layer sheet and cap layer sheet may be formed in a continuous process, wherein the base layer sheet is formed and the cap layer sheet is formed on top of the base layer sheet.
  • the composite sheet may be continuously processed through a pressure roll to integrally attach the base layer sheet and cap layer sheet to one another.
  • the resulting composite sheet may be stored for a period of time or immediately formed into a composite mat.
  • base layer sheet 12 is formed into a sheet having a desired thickness.
  • Cap layer 11 is also formed into a separate sheet having a desired thickness.
  • the cap layer, or a portion thereof is at least partially cured prior to forming a composite sheet. Parameters for partial curing may vary as desired by one of ordinary skill in the art.
  • the cap layer or cap layer portion is partially cured at a temperature of about 200°F to about 275°F for about 15 minutes to about 6 hours.
  • the cap layer or cap layer portion is partially cured at a temperature of about 240°F to about 260°F for about 30 minutes to about 4 hours.

Abstract

L'invention concerne des tapis (10) de sécurité ne glissant pas sur le sol, constitués de deux couches distinctes, superposées, en polymère. La première couche (12), ou couche de base, est constituée d'une première matière polymère, qui offre un premier niveau de souplesse au tapis (10). La seconde couche (11), ou couche supérieure, est constituée d'une seconde matière polymère contenant un colorant, lequel permet de distinguer visuellement les deux couches l'une de l'autre.
