Receiving Properties Spectrum of Highly-Filled Polymers by Surface 'Cementing'

摘要

As a result of theoretical research of experimental data a polymer highly-filled composite CDC (composite durable cement) with the gradient of physico-mechanical and antifriction properties changing in depth which together with high strength and durability has an impact resistant viscous core. It has been determined that combination of nylon with epoxiplastic laquer block copolymer (N+ELBC) and consequent surface "cenmenting" change significantly the materials surface morfology which influences its tribotechnical properties. One of the reasons for increased stability and fatigue durability of CDC oleagen at such surface treatment is rational usage of lubricant (plasticizer) in the friction zone. The article proves efficiency of introduction of multi-purpose fillers (Si, phenol, phenyl-isopropyl-phenylennediamine, sodium nitrate, blacklead) hindering fatigue-crack nucleation by inhibiting thermal decomposition of polymeric matrix and their extension thanks to additional stress relaxation in the outlet zone.
