POLYMERIC COMPOSITE Russian patent published in 2002 - IPC

FIELD: polymers. SUBSTANCE: polymeric composite consists of a mixture of epoxy diane and aliphatic resins, it comprises a mixture of Mannich's base with Schiff's base as a hardening agent and a powder filling agent also. The combination of components of composite taken in the definite ratio provides the attainment of 70% strength indices for 24 h at hardening point and a stable viscosity value. The proposed composite is used in repair of oil pipeline and gas pipeline both in summer and winter conditions and involves the use of metallic clutches and pouring compounds in electronics, electric engineering, building and other aims. EFFECT: improved properties of composite. 2 tbl, 16 ex
