The new polymer composite is based on an ecological phenol-formaldehyde matrix reinforced with a discrete high-modulus fibrous polyamide-benzimidazole filler made of tribotechnical additives. The composite has high properties and is able to work as an antifriction structural material in heavily loaded friction units and aggressive media: dust, abrasive, moisture, high temperature.
A polymer composite has been developed, which in terms of environmental friendliness and strength and performance characteristics exceeds the known world analogues.
Designed for safe coating.
The new polymer composite can be used as an antifriction structural material, that is, plain bearings, bushings, O-rings, bushings, etc., in the machine-building, metallurgical, chemical, and mining industries.
TECHNICAL AND ECONOMIC EFFECT:
The introduction of the created polymer composite exceeds textolite: in terms of impact strength – 170-320 kJ / m2, ultimate strength in static bending – 180-230 MPa, compression – 160-200 MPa, heat resistance according to Martens – up to 210оС, water absorption – 0.40, 5%, coefficient of friction – 0.14-0.24; in terms of performance, it is 1.5 times higher than textolite of metallurgical grade “B”, and it is also more environmentally friendly, since the phenolic compound has a free phenol content of up to 1%, while its content in serial phenolic resins is up to 10%.
Provides consistent results.
