  • Publication number: 20230002616
    Abstract: The invention relates to the technical field of composites, in particular to a high-toughness and high-strength wood-plastic composite and a preparation method thereof. The wood-plastic composite is prepared from the following preparation raw materials in parts by mass: 30-50 parts of wood flour, 11-20 parts of high molecular weight polyethylene, 30-52 parts of polypropylene and 2-10 parts of an interface modifier. Polypropylene is used as a main component of a plastic matrix; high molecular weight polyethylene is used as a secondary component of the plastic matrix and has a toughening effect; wood flour is used as a filler to improve the strength of the wood-plastic composite; the interface modifier can improve the interface bonding between the wood flour and the plastic matrix, and all components have a synergistic effect, so that the obtained wood-plastic composite has high toughness and high strength.

  • Publication number: 20220017742
    Abstract: A rABS/PBT/ASG composite material and a preparation method thereof utilize the characteristics of rABS with carboxyl and hydroxyl groups, wherein rABS are pre-blended with ASG to increase the viscosity, so that the epoxy groups on the ASG molecules react with the hydroxyl groups and the carboxyl groups on the rABS, and the acrylonitrile-styrene segments in ASG and rABS are thermodynamically miscible, followed by reacting and blending with PBT to prepare the rABS/PBT/ASG composite material. ASG acts as a chain extender and solubilizer in the mixture. The mixture prepared in this way have good compatibility, and the tensile strength, impact strength and elongation at break of the composite material are comprehensively improved. The composite material obtained has the advantages of both ABS and PBT materials, which has broad application prospects in the field of ABS plastic recycling.

  • Patent number: 10632656
    Abstract: The present invention discloses a biaxial or tri-axial eccentric rotor volume pulsed deformation plasticizing method and device. The method is characterized in that: the conveying volume of materials formed between two or three engaged eccentric rotors, which are formed by spiral structures and eccentric cylindrical structures connected alternately, and an inner surface of a stator changes periodically along the axial direction and the radial direction of the rotors, achieving the volume pulsed deformation plasticizing and conveying of the materials during engaged rotation of the two or three engaged eccentric rotors. The device's eccentric rotors are all formed by length-varying spiral structures and eccentric cylindrical structures connected alternately; the spiral structures of the eccentric rotors are engaged to each other; the axial positions of eccentric cylindrical structures of the two or three rotors are the same.
