FIELD: chemistry of polymers.
SUBSTANCE: invention relates to a polymeric binding agent for composition materials used as structural materials in machine engineering, aircraft construction and instrument making. Binding agent comprises the following ratio of components, mas. p. p.: epoxy resin ED-20, 50-60; phenolformaldehyde resin RFN-60, 40-50, and additive, 6-7. Mixture of triethanolamine (6 mas. p.) and salicylal-5-methoxy-8-aminoquinoline (0.5 mas. p.) is used as an additive. Invention provides decreasing hardening time, to enhance bending strength and reduce the friction coefficient of the proposed composition material.
EFFECT: improved and valuable technical properties of material.
