阅读说明：本技术 在聚四氟乙烯基体中具有改善的锚固的含有纤维的填料颗粒 (Fiber-containing filler particles with improved anchoring in polytetrafluoroethylene matrix ) 是由 I·奥利格斯-施塔德勒 于 2018-06-13 设计创作，主要内容包括：本发明涉及含有纤维的填料颗粒，其中两种或更多种纤维被至少部分地包封在固体颗粒中，所述固体颗粒由选自聚苯硫醚、液晶聚合物、聚苯砜、聚醚砜、热塑性聚酰亚胺、聚酰胺酰亚胺、环氧树脂、全氟烷氧基聚合物和上述聚合物中的两种或更多种的任何期望混合物的聚合物构成，其中与包封在固体颗粒中的端部相对的纤维中的至少部分的端部从固体颗粒中突出，其中含有纤维的填料颗粒的最大长度为1000μm，并且纤维的最大厚度为100μm。这样的含有纤维的填料颗粒可以通过以下步骤获得：将聚合物与纤维混合，熔融聚合物和/或聚合物组分的化学反应，冷却熔融聚合物和纤维的混合物以得到固体纤维?聚合物复合材料，和粉碎纤维?聚合物复合材料以得到最大长度为1000μm的含有纤维的填料颗粒。(The invention relates to a fiber-containing filler particle, wherein two or more fibers are at least partially encapsulated in a solid particle composed of a polymer selected from the group consisting of polyphenylene sulfide, liquid crystal polymers, polyphenylsulfones, polyethersulfones, thermoplastic polyimides, polyamideimides, epoxies, perfluoroalkoxy polymers, and any desired mixtures of two or more of the foregoing polymers, wherein at least a portion of the ends of the fibers opposite the ends encapsulated in the solid particle protrude from the solid particle, wherein the maximum length of the fiber-containing filler particle is 1000 μm and the maximum thickness of the fibers is 100 μm. Such fiber-containing filler particles can be obtained by the following steps: mixing a polymer with fibres, melting the polymer and/or a chemical reaction of the polymer components, cooling the mixture of molten polymer and fibres to obtain a solid fibre-polymer composite, and comminuting the fibre-polymer composite to obtain fibre-containing filler particles having a maximum length of 1000 μm.)
