  • Patent number: 8591771
    Abstract: Disclosed herein are a dispersed solution of carbon nanotubes including carbon nanotubes, an organic solvent, a spacer, and a dispersant, and a method of preparing the same. The dispersed solution of the carbon nanotubes includes both the spacer, which reduces the van der Waals force of the carbon nanotubes and prevents bundling of the carbon nanotubes, and the dispersant, which maintains the debundling and stability of the carbon nanotubes, thereby improving the dispersibility of the carbon nanotubes. The method of preparing the dispersed solution of the carbon nanotubes can easily produce a dispersed solution of carbon nanotubes without performing a separate chemical treatment.

  • Patent number: 8586651
    Abstract: A method of producing an elastomer composite. The method includes A) combining a first fluid comprising elastomer latex with a second fluid comprising particulate filler; B) causing the elastomer latex to coagulate, thereby forming masterbatch crumb; C) bringing the masterbatch crumb to a water content of about 1 weight percent to about 20 weight percent, thereby forming a dewatered coagulum; D) removing water from the dewatered coagulum by subjecting the dewatered coagulum to mechanical energy, thereby causing the dewatered coagulum to heat as a result of friction, while allowing the dewatered coagulum to achieve a temperature of about 130° C. to about 190° C., wherein water content is reduced to about 0.5% to about 3% and wherein substantially all of the decrease in water content is accomplished by evaporation, thereby producing a masticated masterbatch; and E) subjecting the masticated masterbatch to at least an additional 0.3 MJ/kg of mechanical energy while further reducing the water content.

  • Patent number: 8586665
    Abstract: Commercial thermoplastic clean flame retardant materials in wire and cable insulation are mechanically unstable due to high filler loading. In the present invention, thermoplastic, black color, clean flame retardant composition using carbon nano tubes (CNT) is made. The resultant compositions possess very low smoke and toxicity. CNT with outer diameter of 40-60 nm and length of under 20 ?m are used to increase mechanical properties and flame retardancy. Thermo plastically extruded composition consists of each component by parts by weight as follows: 100 of resin (polyolefin or 100 of polyolefin/ethylene propylene diene monomer (EPDM)), 90-150 of non-halogen containing flame retardants, 1-20 of auxiliary secondary flame retardant agents, 2-4 of CNT (outer diameter of 40-60 nm) and length under 20 ?m and 0.2-1.0 of antioxidants. A reliable method for producing thermoplastic black color clean flame retardant insulation material for wire and cable without deterioration of mechanical properties is discussed.
