Embodiment 1

[0016] Weigh 65% of PEEK, 30% of continuous long glass fiber, 3% of modified graphene, 1% of antioxidant, and 1% of lubricant according to the mass ratio, and mix other materials in a high-speed mixer for 6 minutes except for long glass fiber. 50r / min, fed from the hopper of the twin-screw extruder, the long glass fiber is fed into the first exhaust port by traction, melted, extruded and granulated, then injection molded, and tested according to ASTM standards.

Embodiment 2

[0018] Weigh 65% of PEEK, 30% of continuous long carbon fiber, 3% of modified graphene, 1% of antioxidant, and 1% of lubricant according to the mass ratio, and mix other materials except long glass fiber in a high-speed mixer for 6 minutes at a mixing speed of 50r / min, fed from the hopper of the twin-screw extruder, the long glass fiber is fed into the first exhaust port by traction, melted, extruded and granulated, then injection molded, and tested according to ASTM standards.

Embodiment 3

[0020] Weigh 65% of PEEK, 20% of continuous long glass fiber, 10% of continuous long carbon fiber, 3% of modified graphene, 1% of antioxidant, and 1% of lubricant according to the mass ratio. Medium mixing for 6 minutes at a mixing speed of 50r / min, adding from the hopper of a twin-screw extruder, adding long glass fibers at the first exhaust port after being drawn, and injection molding after melt extrusion and granulation, and tested according to ASTM standards.

[0021] The product performance is shown in Table 1.

Abstract

The invention discloses an enhanced antistatic polyetheretherketone composite material, which is prepared from the following components in parts by weight: 45-60 parts of polyetheretherketone, 15-40 parts of continuous fiber, 0.5-5 parts of graphene, 0.1-5 parts of coupling agent and 0.1-5 parts of processing agent. The invention also discloses a preparation method of the enhanced antistatic polyetheretherketone composite material, wherein the continuous fiber is charged from a first exhaust opening of an extruding machine under the function of a traction machine. The polyetheretherketone composite material disclosed by the invention has the advantages of high surface quality, stable production process, simplicity in operation, obviously improved mechanical performance and thermal performance, and capability of meeting antistatic requirement.

Description

technical field [0001] The invention provides an enhanced antistatic polyether ether ketone composite material and a preparation method thereof, belonging to the field of composite materials. Background technique [0002] Polyetheretherketone (PEEK), as a new type of semi-crystalline aromatic plastic engineering plastic, has excellent physical and mechanical properties, and can replace traditional materials such as metals and ceramics in many special fields, reducing weight and improving performance. With outstanding contributions, it has become one of the most popular high-performance engineering plastics today. PEEK still has excellent insulation and stable electrical properties in high temperature, high pressure, high speed, high humidity and other environments. In order to broaden the application range of PEEK, in the field of anti-static, the market often uses inorganic fillers such as carbon fiber or carbon black directly. The antistatic polyether ether ketone composi...
