Composite material sliding bearing with base of high-temp polymer

Abstract

This invention discloses a high-temp polymer matrix compound material sliding bearing which is processed according to conventional formation method with the compound material made of high-temp polymer matrix resin with functional additives, reinforced fiber and agent. The said matrix resin is made by teflon mixed with and / or polyamide and modified and the said function additives are nm or mm level mineral nonmetal fillers in which, at least one kind is particle of nm level. This invention provides a low friction ratio, good wearness, long working time, high PV, value, self lubricating compound material sliding bearing.

Description

[0001] (1) The technical fields mentioned

[0002] The invention belongs to the technical field of polymer-based sliding bearings, and in particular relates to a self-lubricating composite material sliding bearing with a high-temperature-resistant polymer as a matrix, fiber reinforcement and functional fillers containing friction-reducing and anti-wear micropowder. (2) Background technology

[0003] Due to the advantages of good self-lubricating performance, corrosion resistance, shock and noise reduction, resistance to foreign matter intrusion, low cost, and energy saving, polymer-based composite bearings have always been one of the key directions in the research and development of new bearings. However, due to the high temperature sensitivity, poor heat resistance, low thermal conductivity, poor dimensional stability, and easy creep of the matrix material polymer, the technical performance and application range of composite material bearings have been restricted. It is usual...
