Carbonaceous fibre filling polytetrafluoroethylene and method of producing the same

Abstract

The invention discloses an oil-free lubrication element material-low cost carbon fiber filling politef and preparing method on general purpose reciprocated compressor, which is characterized by the following: comprising with 60-80% politef, 10-35% sum of carbon fiber and carbon powder and not more than 15% filling agent; setting carbon fiber : carbon powder as 1 : 0. 5-1. 5; choosing the filling agent from one or more than one black lead, glass fiber, molybdenum disulfide and copper powder; mixing at normal temperature; getting the product. This invention possesses long lifespan, low cost and wide applicability.

Description

technical field [0001] The invention relates to the material of the oil-free lubricating element used in the general reciprocating compressor-filled polytetrafluoroethylene and its manufacturing method, in particular to a low-cost filled polytetrafluoroethylene and its manufacturing method. Background technique [0002] At present, carbon fiber abrasive powder filled polytetrafluoroethylene products have been widely used in the reciprocating compressor industry as a material for oil-free lubricating components used on reciprocating compressors. Due to the high price of carbon fiber, the use of carbon fiber-based filled PTFE material has the characteristics of high cost, and a large amount of use will lead to a substantial increase in cost. There is an urgent need for materials for oil-free lubricating components that can meet technical requirements and reduce costs. . Contents of the invention [0003] In view of the above problems, the object of the present invention is ...
