COMPOSITE FRICTIONAL POLYMER MATERIAL

摘要

FIELD: chemistry.SUBSTANCE: invention relates to polymer-based composite frictional nonmetallic materials and specifically to phenol-formaldehyde resin-based materials and can be used in making shock-absorbers, clutch couplings, brake assemblies etc. The composite frictional polymer material contains, wt %: phenol-formaldehyde resin 25-33; zinc stearate - 0.6-1.2; kaolin - 15-23; graphite - 8-19; asbestos - the balance.EFFECT: high wear resistance of both the composition and the counterface, while maintaining the required coefficient of friction in the friction pair.2 tbl, 1 ex
