摘要： A rubber-graphene composite includes a paste and a rubber matrix, wherein the paste is mixed with the rubber matrix. The paste includes graphene, a plasticizer, and at least one additive selected from the group consisting of carbon black, biochar, and rice husk ash silica. A method for preparing a rubber-graphene composite includes mixing graphene with a plasticizer and at least one additive selected from the group consisting of carbon black, biochar, and rice husk ash silica to form a paste; mixing the paste with a rubber matrix to form an intermediate composite; accelerating the intermediate composite to form a final composite; and extruding and curing the final composite.

摘要： Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. Formation of printed objects having various colors may sometimes be desirable. Thermoplastic particulates incorporating a color-changing material capable of forming different colors under specified activation conditions may impart different colors to a printed object. Such particulate compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer and a color-changing material associated with the thermoplastic particulates, wherein the color-changing material is photochromic and thermochromic. Conjugated diynes, such as 10,12-pentacosadiynoic acid or a derivative thereof, may be particularly suitable color-changing materials having photochromic and thermochromic properties for forming a range of colors upon a printed object. Nanoparticles, particularly silica nanoparticles, associated with an outer surface of the thermoplastic particulates may enhance the brightness of the color obtained under various activation conditions and afford coloration permanence.

摘要： A method of forming a finished film comprising extruding a molten polyethylene comprising a diene terpolymer modifier through a die opening to form a film, wherein the diene-terpolymer modifier is a terpolymer comprising ethylene-derived units, C3 to C10 α-olefin derived units, and diene-derived units; causing the film to progress in a direction away from the die opening; cooling the film at a distance from the die opening, the distance adjusted to allow relaxation of the molten polyethylene prior to solidification and/or crystallization upon cooling; and isolating a finished film therefrom. Desirably, the polyethylene is a linear low density polyethylene, and the die and cooling is suitable for forming a blown film.

摘要： An apparatus for manufacturing a rubber member includes an extruder; a mouthpiece; and a support surface which faces the mouthpiece in an opposed manner. The apparatus further includes: a rubber pool portion formed between the mouthpiece and the support surface; and a closing surface having an inclined surface shape and capable of closing a moving-direction front side of the rubber pool portion. A rubber material is ejected from an ejection port in a state where the rubber pool portion is closed by the closing surface, the support surface and the mouthpiece are moved relative to each other after the rubber pool portion is filled with the rubber material, and a lamination starting end of the rubber material is pressed to the closing surface thus molding the lamination starting end into an inclined surface and, thereafter, the closing surface is moved in a direction away from the support surface.

摘要： An underwater pelletizing method for pelletizing brittle hydrocarbon resins with low melt viscosity. A feed material comprising the hydrocarbon resin is formed into a melt, extruded through a die into a water bath below the Tg of the hydrocarbon resin to form a plurality of extrudates and cut adjacent the die surface to form a slurry of resin pellets. A graft monomer and/or other reactants, such as a hydrosilylation agent, may be introduced into the resin melt to chemically modify the hydrocarbon resin.

摘要： Provided are a multilayer film, a method for producing the multilayer film, and a method for producing a molded body. The multilayer film has excellent three-dimensional overlaying formability and adhesiveness after being formed; can easily be used when being bonded to an adherend; maintains adhesive strength. Specifically, the multilayer film has: an adhesive layer comprising a thermoplastic polymer composition containing a thermoplastic elastomer (A) which is a block copolymer or a hydrogenated product thereof having a polymer block (a1) containing aromatic vinyl compound units and having a polymer block (a2) containing conjugated diene compound units; and a base layer comprising an amorphous resin which has a modulus of elasticity of 2 to 600 MPa at an arbitrary temperature of 110 to 160° C. The tensile elongation at break of the multilayer film at a temperature 5° C. lower than the glass transition temperature of the amorphous resin is at least 160%.
