Problems solved by technology

[0004] At present, the preparation method of nano-powder modified polyether ether ketone composite material is to use twin-screw extrusion granulation after ball milling or high-speed stirring, or hot pressing, injection molding; but due to the high melting temperature of PEEK, the viscosity after melting is very large , insoluble in any solvent, poor wettability, large specific surface area and surface effect of nano powder, and easy agglomeration of nano powder due to its own characteristics, resulting in easy agglomeration of nano powder particles in PEEK matrix, and the traditional method of preparing nano Poor bonding between powder and PEEK interface

Abstract

The invention provides a nano-powder/polyether-ether-ketone composite material and a preparation method thereof, and the nano-powder/polyether-ether-ketone composite material comprises the following components: polyether-ether-ketone and magnetic nano-powder, and the magnetic nano powder is one or two or more of nano ferroferric oxide, nano Fe powder, nano Ni powder, nano Co powder, and alloy nano powder (such as FeNi, FeCo and the like) or oxides. According to the preparation method, firstly, a magnetic nano-powder/diphenyl sulfone composite material is prepared, and when PEEK powder is generated through a condensation polymerization reaction, the PEEK powder grows by taking nano-powder as a crystal nucleus, so that the nano-powder can be prevented from being agglomerated; diphenyl sulfone is different from PEEK, can be dissolved in an organic solvent, is low in melting temperature and viscosity, and is easy for preparing a nano composite material with uniformly dispersed nano particles; and in the PEEK synthesis reaction process, the nano powder is always in diphenyl sulfone, agglomeration of the powder can be reduced as much as possible, and due to nitrogen protection, oxidation reaction cannot occur.

Description

technical field [0001] The invention belongs to the field of thermoplastic composite materials, and in particular relates to a nanometer powder / polyether ether ketone composite material and a preparation method thereof. Background technique [0002] Polyether ether ketone (PEEK) is a rigid semi-crystalline polymer with heat resistance, abrasion resistance, fatigue resistance, radiation resistance, peel resistance, creep resistance, dimensional stability, impact resistance , chemical resistance, non-toxic, flame retardant and other excellent comprehensive properties, and the two ether bonds and carbonyl groups in its structure provide flexibility and excellent manufacturability for the material. Therefore, PEEK is widely used in many fields such as electronics, aerospace, automobiles, energy and other industries, and medical treatment. [0003] Nanomaterials, due to their size close to the wavelength of light and special effects of large surfaces, often have properties diffe...
