Embodiment 1

[0022] Embodiment 1 Preparation of nanodiamondene

[0023] The steps are: (1) Preliminary crushing: send the diamond raw material into the ball mill shaping barrel, after passing through the back and forth ball mill crushing and shaping process of steel balls of different particle sizes under high-speed rotation, pass through a certain mesh mesh at the receiving port of the ball mill The mesh of the mesh is not less than 70 mesh, and the ball mill shaping time is generally controlled within 1-5 hours, and the 70 mesh coarse material is automatically returned to the ball mill for ball mill shaping again; the collected particles above 70 mesh are passed through multi-layer The vibrating sieve machine is used for the primary particle size classification, and the sieve meshes are arranged from high to low from 100 mesh to 800 mesh. The time of vibrating sieve is generally 30min-2h. The material can be used for other purposes. At the same time, in order to ensure the accuracy of th...

Abstract

The invention discloses a thermoplastic polymer composite material containing nano diamond ene, and belongs to the technical field of high polymer materials. The thermoplastic polymer composite material is prepared from, by weight, 90-95 parts of a thermoplastic polymer and 5-10 parts of nano diamond ene. A corresponding preparation method of the thermoplastic polymer composite material comprises the following steps that 1, the thermoplastic polymer and nano diamond ene are mixed in proportion; 2, melt extruding, drawing, cooling, pelletizing and drying are conducted on a double-screw extruder, and then the thermoplastic polymer composite material is obtained. According to the thermoplastic polymer composite material, nano diamond ene is added into the thermoplastic polymer, the heat conductivity coefficient of the polymer material is 5-10 W/(m.K), and the heat conductivity of the overall polymer material is improved; the composite material has a lamellar single crystal structure and is high in strength and good in wear resistance, the strength of the polymer material is improved, and the service life of the polymer material is prolonged; the preparation method of the composite material is simple and low in production cost, and only the double-screw extruder is utilized as the equipment.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a thermoplastic polymer composite material containing nano-diamondene and a preparation method thereof. Background technique [0002] Thermoplastic polymers refer to plastics that soften when heated, solidify when cooled, and can be softened again. At present, commercial thermoplastic polymers mainly include: polyethylene (PE), polypropylene (PP), polystyrene (PS), polymethyl methacrylate (PMMA), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), etc., because this material has the advantages of good flexibility, high corrosion resistance, light weight, electrical insulation, and low cost, it is widely used in technical fields such as electronic products, electronic packaging, automobiles, aerospace, and LED lighting. For example: light-emitting packages in electrical and electronic devices are generally made of thermoplastic polymer materials. Howe...
