    Abstract: The present invention relates to a method for producing a conductive masterbatch containing a polyamide resin and a carbonaceous filler. The present invention provides a method for producing a conductive masterbatch which can suppress an increase in resin temperature during extrusion, formation of die drips, and strand breakage and can also significantly increase the output of extruding. The method is achieved by the steps of feeding the carbonaceous filler to a molten first polyamide to melt-knead them together and then feeding a second polyamide to the resulting melt-kneaded product to further melt-knead the second polyamide, the carbonaceous filler, and the first polyamide.

  • Patent number: 7612129
    Abstract: A paint manufacturing method includes receiving each of a group of fluid prepaints at different inputs of a fluid component mixing system, determining at a computer system a first fluid prepaint ratio, and mixing the fluid prepaints in accordance with the first ratio to form a base paint at an output of the mixing system. A paint manufacturing system includes a computer-controlled prepaint mixing system. The prepaint mixing system includes multiple fluid inputs providing for computer-controllable flow of prepaints into the mixing system. The computer system includes a memory storing software instructions that configured the computer system to receive user input selecting a base paint to be produced, determine a ratio of fluid prepaints needed to produce the base paint, and regulate each fluid flow control to establish, in the determined ratio, a flow of fluid prepaints entering the fluid mixing system.

  • Patent number: 7592388
    Abstract: The present invention relates to a high melt flow thermoplastic resin filled with long fibers, such as long glass fibers, stainless steel fibers, carbon fibers, aramid fibers, or other like fibers, and having high melt flow properties. The high melt flow properties of the thermoplastic resin contribute to its ease of production, allowing for the production of long fiber-reinforced thermoplastic compositions having good dispersion and wet-out in the pellet and molded article, and characterized by low levels of loose fiber in the pellet and/or compound. Although any concentration of fibers may be present in the fiber-reinforced thermoplastic composition, the high melt flow thermoplastic resins are especially suitable for high concentrate long glass fiber-reinforced thermoplastic compositions.

Optionally, additional materials are compounded into the masterbatch, e.g., additives, other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill. Excellent control of Mooney Viscosity is achieved. In certain preferred embodiments, elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a coagulated mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor.

    Abstract: Clays and organoclays which are treated with resorcinol diphosphate and/or bisphenol diphosphate as general nanoparticle particle dispersants and replacements for quaternary amines. The two compounds are used as self-activating and self-dispersing nanoparticles by localizing themselves on the particle surface in a polymer matrix and acting as a nanoparticle dispersants in general, as well as resulting in exfoliation of clays. The exfoliate clays may be used in polymers in lieu of other organic treatments. When these clays exfoliate poorly in a given thermoplastic, they can be added in high loading rates to polymethylmethacrylate and the PMMA-clay masterbatch added to the plastic where the organoclay performed poorly. The resulting material is a desirable nanocomposite material, with good exfoliation of the organoclay obtained in the final receiving thermoplastic.
