Problems solved by technology

Although PEEK has achieved mass production in my country, compared with foreign companies, there is still a gap in the application and development of PEEK, especially the development of special materials is a blind spot, and the grades are relatively single
[0003] In the field of wire and cable, although polyether ether ketone has many excellent properties, due to its high strength, high modulus, high fracture toughness and other characteristics, its processing characteristics are not suitable for direct application in the cable industry, and it is difficult to directly apply to wire and cable manufacturing

Abstract

The invention provides a polyether-ether-ketone cable material. The polyether-ether-ketone cable material is characterized in that a raw material formula comprises the following materials in parts by weight: 50-70 parts of polyether-ether-ketone, 1-5 parts of a lubricating agent, 0.1-1 part of a nucleating agent, 3-8 parts of a compatilizer and 25-40 parts of a hardness conditioning agent. A preparation method of the polyether-ether-ketone cable material is characterized by comprising the following steps of weighting the materials according to the mass part of the materials in the raw material formula, mixing and stirring all the materials for 15-30 minutes in a high-speed mixing machine, then discharging, pelleting through a double-screw extruder at the process temperature of 220-380 DEG C, and packaging. The polyether-ether-ketone cable material provided by the invention has the advantages that the machining property of the polyether-ether-ketone product is improved, the extrusion molding is facilitated, the hardness of the material is reduced, the polyether-ether-ketone is suitable for being applied to cable industries, the excellent property of polyether-ether-ketone material can also be retained, and the polyether-ether-ketone cable material is flame-retardant, resists high temperature, low temperature, corrosion, oil and abrasion and can be widely applied to automobile cables, locomotive cables, nuclear power and the like with strict operating requirements.

Description

technical field [0001] The invention belongs to the technical field of wire and cable materials, and in particular relates to a polyether ether ketone cable material and a preparation method thereof. Background technique [0002] Polyether Ether Ketone (PEEK for short) is a new semi-crystalline aromatic thermoplastic engineering plastic with high glass transition temperature (Tg= 143°C) and melting point (Tm= 334°C). Long-term use at 250°C, high temperature resistance is very superior, and it has high strength, high modulus, high fracture toughness and excellent dimensional stability, and also has excellent chemical resistance. Under normal conditions, only concentrated sulfuric acid can dissolve it. Polyether ether ketone itself has flame retardancy, releases very little smoke and toxic gases under flame conditions, and has strong radiation resistance; it has excellent fatigue resistance under alternating stress conditions; it has good wear resistance and has Stable insul...
