  • Thermoplastic composite material, preparation method therefor and use thereof
    Patent number: 12508784
    Abstract: A thermoplastic composite material has an inner layer material and at least one layer of outer layer material. The inner layer material is a core layer that contains fiber bundles, a first thermoplastic resin and a first auxiliary agent; and the at least one layer of outer layer material wraps the core layer and is a resin layer comprising a second thermoplastic resin and an optional second auxiliary agent. The fiber bundles extend continuously from one end of the core layer to the opposite end thereof. The inner layer-outer layer composite structure improves the processing performance of the thermoplastic composite material and the lubricity between fibers and resin matrixes during injection molding, and improves the fluidity of the fibers in a resin matrix melt.

  • POLYPROPYLENE MICROSPHERE AND PREPARATION METHOD THEREFOR, 3D PRINTING RAW MATERIAL, AND USE
    Publication number: 20250236753
    Abstract: A polypropylene microsphere and a preparation method therefor, a 3D printing raw material, and a use are provided. The polypropylene microsphere contains 0.2 wt %-10 wt % of a structural unit derived from ethylene and 90 wt %-99.8 wt % of a structural unit derived from propylene. A melting heat absorption curve of the polypropylene microsphere is obtained by means of a differential scanning calorimeter (DSC), and a half-peak width (Wm) of the melting heat absorption curve of the polypropylene microsphere is 4-10° C. The crystallization sequence distribution of the polypropylene microsphere is uniform, and when the polypropylene microsphere is used for 3D printing, 3D printing melting is uniform.
