Abstract

The invention relates to a high-mobility TLCP / PES / PEEK composite material and a preparation method thereof. The composite material is composed of the following components in parts by mass: 100 parts of PEEK, 10-60 parts of PES, 5-10 parts of TLCP, 0.5-1 part of a lubricant, and 0.1-0.5 part of an antioxidant. The preparation method of the TLCP / PES / PEEK composite material comprises the following steps: after drying the TLCP, the PES, the PEEK, the lubricant and the antioxidant, adding the components into a high-speed mixer according to the proportion, mixing evenly, adding the mixed material into a double-screw extruder, and carrying out melt extrusion; and carrying out air cooling, granulation and packaging to obtain the TLCP / PES / PEEK composite material. With addition of the PES and the TLCP, the mobility, the glass transition temperature and the wear resistance of the PEEK are improved, and the application field of the PEEK material is widened.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high-fluidity TLCP / PES / PEEK composite material and a preparation method thereof. Background technique [0002] Polyether ether ketone (PEEK) is a kind of polyarylether ketone, which is a crystalline, opaque, light tea gray aromatic super heat-resistant thermoplastic resin. PEEK has outstanding high temperature resistance and thermal performance. It can be used for a long time at 250°C, and the instantaneous use temperature can reach 300°C. The resin has a high glass transition temperature (143°C) and melting point (334°C). Its thermal deformation temperature under load is as high as 316°C, and its continuous use temperature is 260°C. PEEK has high rigidity, dimensional stability, and small linear expansion coefficient, which is close to metal aluminum materials; PEEK has good chemical stability, and has strong corrosion resistance to acids, alkalis and almost all organic solve...
