Embodiment 1

[0027] The materials are weighed in parts by weight, wherein the polyarylethersulfone resin is selected from 100% PPSU, the soft wear-resistant filler is selected from graphite, and the hard wear-resistant filler is selected from potassium titanate whiskers; the weighed materials and processing aids are put into Stir in a high-speed mixer for 3 minutes to mix evenly. After drying at 100°C for 2 hours, melt and extrude to granulate through a screw extruder. Extrusion temperature: 320°C, speed: 200rpm.

Embodiment 2

[0029] Take the material by parts by weight, wherein the polyaryl ether sulfone resin is selected PPSU:PES=50%:50%, the soft wear-resistant filler is selected graphite, and the hard wear-resistant filler is selected potassium titanate whisker; The materials and processing aids were put into a high-speed mixer and stirred for 3 minutes to mix evenly. After drying at 100°C for 2 hours, they were melt-extruded and granulated through a screw extruder. Extrusion temperature: 320°C, speed: 200rpm.

Embodiment 3

[0031] The materials are weighed in parts by weight, wherein the polyaryl ether sulfone resin is selected from PPSU:PES:PSU=70%:20%:10%, the soft wear-resistant filler is selected from polytetrafluoroethylene, and the hard wear-resistant filler is selected from silicon carbide; Put the weighed material and processing aid into a high-speed mixer and stir for 5 minutes to mix evenly. After drying at 120°C for 3 hours, melt and extrude the pellets through a screw extruder. Extrusion temperature: 300°C, speed: 300rpm .

Abstract

The invention provides a polyaryl ether sulfone composite material and an application thereof. The polyaryl ether sulfone composite material disclosed by the invention comprises the following components in percentage by weight: 45%-80% of polyaryl ether sulfone resin, 15%-30% of soft wear-resistant filler, 5-20% of hard wear-resistant filler and 0%-5% of a processing aid. According to the composite material, the polyaryl ether sulfone resin with good size stability and excellent creep resistance and mechanical property is used as a resin matrix is selected, and the hard wear-resistant filler and the soft wear-resistant filler are used for compounding and modifying, so that the wear-resistant requirement of the material is met, and meanwhile, low noise pollution is caused. Friction performance of the prepared composite material can achieve a dynamic friction coefficient of 0.26, the abrasion is 17*10<-6> (mg / Nm), and the lowest noise can reach 40 dB.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a polyarylethersulfone composite material and its application. Background technique [0002] As an important variety of special engineering plastics, polyarylethersulfone has been commercialized in three varieties, namely polysulfone (PSU), polyethersulfone (PES) and polyphenylenesulfone (PPSU). Polyarylethersulfone has excellent mechanical properties, dielectric properties, heat resistance, flame retardancy, creep resistance, chemical stability, transparency and food hygiene, and has been approved by the US Food and Drug Administration (FDA) Certified for contact with food and drinking water. Therefore, such polymers have been widely used in the fields of electronics, automobiles, medical and health care, and household food. [0003] In the prior art, polyarylethersulfone wear-resistant composite materials are usually prepared by using one or ...
