Embodiment 1
[0022] As shown in formula 2 in Table 1, the raw material is 1598 grams of polyether ether ketone resin (PEEK) with a melt index of 23 g / 10 min, 2 grams of high-temperature lubricant GENIOPLAST Pellet S, premixed with a high-speed mixer, and continuous basalt fiber in WP- The WSZ-φ30 twin-screw extruder is melted and compounded. The barrel of the extruder adopts an eight-stage heating mode. The purpose is to prevent the material from melting at the feed port, so as to avoid the blockage of the feed port), control the basalt fiber content to 20wt% (400 grams), extrude and granulate, and the screw torque is 50~55Nm. 2000 grams of basalt fiber reinforced polyetheretherketone composite material with 0.1wt% high-temperature lubricant added, 20wt% basalt fiber added and 79.9wt% polyetheretherketone resin was obtained. By changing the proportion of polyetheretherketone resin (PEEK) and high-temperature lubricant, basalt fiber-reinforced polyetheretherketone composites with different ...

Abstract
The invention belongs to the field of macromolecule and a composite thereof, in particular to a basalt fibre reinforced polyetheretherketone (PEEK) composite and a preparation method thereof. The composite contains 50.0-95.0wt% of PEEK resin, 0-5.0wt% of high-temperature lubricant, 0-10.0wt% of viscosity regulator and 5.0-50.0wt% of basalt fibre reinforced material. The melt index of the PEEK resin is 20-200g / 10min, the high-temperature lubricant is granulated or powdery GENIOPLAST Pellet S lubricant produced by Wacker Company in Germany, and the viscosity regulator is a polyaryletherketone liquid crystal polymer (PAEKLCP). The basalt fibre reinforced PEEK composite produced by the method can be widely applied to the fields of aerospace, military hardware and other civil high technologies, such as high-temperature resistant connectors, various mechanical components and the like.
Description
technical field [0001] The invention belongs to the field of polymers and composite materials thereof, and in particular relates to a basalt fiber reinforced polyetheretherketone (PEEK) composite material and a preparation method thereof. Background technique [0002] Fiber-reinforced thermoplastic PEEK resin-based composites have been successfully developed and put into the market by the British ICI company in the 1980s. Due to their high service temperature, strength, and dimensional stability, they have been widely used in aviation, aerospace and other high-tech industries. field has been successfully applied. However, its development, commercial production and promotion are mainly concentrated abroad, and the types of fibers are limited to glass fiber and carbon fiber. Basalt fiber is currently the only high-performance fiber without environmental pollution. It has a series of performance advantages. It can replace glass fiber and even more expensive carbon fiber to pre...
