THICKLY FILLED COMPOSITE MATERIAL SYNTHEGRAN Russian patent published in 1998 - IPC

FIELD: organic chemistry; production of synthetic structural materials used as substitutes for natural granites, diabases, gabbro-diabases and other natural hard rocks for manufacturing components of machine-tools, control-and-measuring machines and other precision engineering items production of building and facing materials. SUBSTANCE: SYNTHEGRAN has the following composition, %: epoxy diane resin, 4.2-7.0; active diluent, 0.6-1.5; aminic curing agent, 1.2-2.0; mixture of paraffin C₁₀H₂₂- C₁₁H₂₄ hydrocarbon and polymethylsiloxane, 0.05-0.5; hard rock crushed to 0.063-0.315 mm grain size, 15-25; 0.63-10.0 mm fraction hard rock, the balance. Paraffin hydrocarbons and polymethylsiloxane are mixed together in weight ratio 5:1. As active diluent, material employs alkyl(aryl)glycidyl ether or diglycidyl ether of diatomic C₄- C₆. alcohols. EFFECT: higher efficiency. 3 cl, 2 tbl
