Example Embodiment

[0044] Correspondingly, the embodiment of the present invention also provides a method for preparing a polyphenylene ether composite material, including the following steps:
[0045] S10. Mixing the dried polyphenylene ether, liquid crystal polyester resin and filler to obtain a mixture;
[0046] S20. After the mixture is melted and kneaded, it is extruded and pelletized to obtain a polyphenylene ether composite material.
[0047] The method for preparing a polyphenylene ether composite material provided by the embodiment of the present invention includes mixing dry polyphenylene ether, liquid crystal polyester resin, and filler, and then performing melt mixing, extrusion and granulation to obtain a polyphenylene ether composite material. In the embodiment of the present invention, the polyphenylene ether composite material containing polyphenylene ether, liquid crystal polyester resin and fillers, etc., through the interaction between the components, the polyphenylene ether composite material has high mechanical properties and melt flow. Good performance, excellent thermodynamic properties, etc., can be directly mixed uniformly, and then prepared by melt mixing, extrusion and granulation. The process is simple, suitable for large-scale industrial applications, and can be widely used in electronic appliances, automobiles, household appliances, and office equipment And industrial machinery.
[0048] Specifically, in the above step S10, the dried polyphenylene ether, the liquid crystal polyester resin and the filler are mixed to obtain a mixture. In some embodiments, after drying the polyphenylene ether, liquid crystal polyester and filler at 130-160°C for at least 5 hours, the mixing process is performed, and the moisture is removed by the drying process, so that the composite material has better mixing and granulation performance.
[0049] In some embodiments, the polyphenylene ether is selected from at least one of PPO-P640, PPO-Xb040, PPO-FMC3008, and PPO-HF185.
[0050] In some embodiments, the liquid crystal polyester is selected from wholly aromatic liquid crystal polyester resins.
[0051] In some embodiments, the filler is selected from at least one of glass fiber, whisker, wollastonite, talc, mica, titanium dioxide, carbon black, calcium carbonate, clay, barium sulfate, and silica.
[0052] In some embodiments, the wholly aromatic liquid crystal polyester resin is prepared from a first aromatic monomer and a second aromatic monomer through condensation polymerization. In some specific embodiments, the first aromatic monomer is selected from at least one of aromatic diols, aromatic diamines, and aromatic hydroxylamines; and the second aromatic monomer is selected from: aromatics At least one of dicarboxylic acid, aromatic hydroxycarboxylic acid, and aromatic aminocarboxylic acid. The fully aromatic liquid crystal polyester resin of the embodiment of the present invention is composed of at least one monomer of aromatic diol, aromatic diamine, and aromatic hydroxylamine and aromatic dicarboxylic acid, aromatic hydroxycarboxylic acid, and aromatic aminocarboxylic acid. The fully aromatic liquid crystal polyester resin prepared by this method has excellent heat resistance, electrical insulation, dimensional stability and fluidity during melting, and can effectively improve polystyrene. The fluidity, stability and mechanical properties of ether composites.
[0053] In some embodiments, at least one monomer of aromatic diol, aromatic diamine, and aromatic hydroxylamine is combined with at least one of aromatic dicarboxylic acid, aromatic hydroxycarboxylic acid, and aromatic aminocarboxylic acid. The monomers are firstly polycondensed by solution polycondensation method or bulk polycondensation method, and then solid-phase polycondensation is performed under a protective gas atmosphere such as nitrogen and argon at a characteristic temperature. Wherein, the specific heating temperature of the solid-state polycondensation reaction is different due to the selected reaction monomer, and cannot be defined here. The heating treatment can be carried out by heating plates, hot air, high-temperature fluids and other methods. In addition, in order to remove the by-products of the solid polycondensation reaction, inert gas purging or vacuum cleaning can be used.
[0054] In some embodiments, before performing the polycondensation reaction, the method further includes pretreating the first aromatic monomer and the second aromatic monomer with an acylating agent, and the reaction monomer can be improved by the pretreatment. Specifically, the acylating agent includes but is not limited to an acetylating agent, which can acetylate the reactive monomer to improve its reactivity.
[0055] In some embodiments, the liquid crystal polyester is selected from wholly aromatic liquid crystal polyester resins. In some specific embodiments, the wholly aromatic liquid crystal polyester resin includes: -O-Ar-O-, -HN-Ar-NH-, -HNAr-O-, -O-Ar-CO-, -HN -At least one repeating unit in Ar-CO-, where Ar is selected from substituted or unsubstituted: phenylene, biphenylene, naphthalene, two phenylene aromatics bonded by carbon or non-carbon elements At least one of the group of compounds.
[0056] Specifically, in the above step S20, after the mixture is melted and kneaded, the mixture is extruded and pelletized to obtain a polyphenylene ether composite material. In the embodiment of the present invention, the homogeneously mixed components are melted and kneaded, and then extruded, drawn, cooled, and pelletized to produce a high-fluidity and high-performance polyphenylene ether compound. The preparation process is simple and suitable. For large-scale industrial application, it has strong practicability.
