COMPOSITION FOR COMPOSITE MATERIAL Russian patent published in 1997 - IPC

FIELD: building materials production, particularly, polymer composites of the base of thermoreactive resin which are used in construction units operating in aggressive mediums, at high dynamic stress and at alternating temperature. SUBSTANCE: composition comprises, mas.%: furfurol-acetone resin, 14.0-20.0; benzenesulfoacid, 3.0-5.0; andesite flour, 47.0-57.0; technical carbon black, 2.5-5.7; woody chips, 16.0-20.0; crushed glass or untied glass band, 0.3-0.5; low molecular styrene-containing copolymer on the base of vat residue of rectification of recurrent solvent of production of butadiene rubber (styrene content in it is 50-80 mass %), 1.0-5.0; polyhydric alcohol, 0.3-1.5. Compressive strength of material is 80.0 MPa, its bending strength is up to 30.0 MPa; coefficient of resistance in water is up to 0.722, cold resistance is up to 440 cycles. EFFECT: improved operation features of composite material. 2 tbl
