Title of Invention

A RUBBER ARTICLE WITH ENHANCED MECHANICAL PROPERTIES, CAPABLE OF WITHSTANDING A MINIMUM VERTICAL LOAD OF 15-20 MT/SFT, AND PROCESS FOR PREPARING THE SAME.

Abstract TITLE: A RUBBER ARTICLE WITH ENHANCED MECHANICAL PROPERTIES, CAPABLE OF WITHSTANDING A MINIMUM VERTICLE LOAD OF 15-20 MT/SFT, AND PROCESS FOR PREPARING THE SAME. CONVENTIONALLY WOOD OR METAL WAS USED FOR MAKING PIPE RAFT ANDTHE PIPES KEPT ON THE RAFT WERE USED FOR DRILLING AND WORKOVER RIGS IN AND AROUND OIL WELL FOR EXTRACTING PETROLEUM. WOODEN PLATFORMS ON METAL STRUCTURES WERE COSTLY, NOT RESISTANT TO THE ACTION OF WATER AND CHEMICALS AND AND RESULTED IN DEFORESTATION. THIS INVENTION AIMS AT OVERCOMING THESE PROBLEMS AND PROVIDES A RUBBER ARTICLE LIKE MAT, SHEET BLOCK AND THE LIKE WITH ENHANCED MECHANICAL PROPERTIES, CAPABLE OF A RUBBER ARTICLE WITH ENHANCED MECHANICAL PROPERTIES, CAPABLE OF WITHSTANDING A MINIMUM VERTICAL LOAD OF 15-20 MT/SFT. PREPARED FROM POLYCHLOROPRENE RUBBER (CR) AND NATURAL RUBBER (NR) VARYING BETWEEN THE FOLLOWING PROPORTIONS : CR:NR::2:1 TO 3:1 PARTS BY WEIGHT, AND INCORPORATING POLYAMIDE FABRIC FOR IMPARTING IMPROVED MECHANICAL STRENGTH AND RESISTANCE TO WATER, OIL AND CHEMICALS AND FURTHER INCORPORATING FILLERS, ACTIVATOR,ANTI-OXIDANT, PLASTICIZER, ACCELERATOR AND VULCANISING AGENT IN THE FINAL COMPOSITION BEFORE MOULDING INT HE DESIRED SHAPE, SIZE AND CONFIRURATION. THE PRESENT INVENTION ALSO RELATES TO A PROCESS FOR PREPARING THE ABOVE RUBBER ARTICLES WITH ENHANCED MECHANICAL PROPERTIES.
