PRESS-COMPOSITION Russian patent published in 1995 - IPC

FIELD: electric engineering. SUBSTANCE: press-composition has, mas. p.: thermoreactive polyorganosiloxane resin 100; filler (fiber glass, fluoroplastic, asbestos, crushed quartz, boron nitride, aluminium oxide, talc, aerosil) 100-250; copper dialkyldithiophosphate of the general formula [(RO)₂P(S)S]]₂Cu where R - C₂-C₄-alkyl 0.0025-0.5 and/or O-carboxybenzoylferrocene transient metals complex salt of the general formula A₂M where A - C₁₀H₉FeCoC₆H₄COO; M - Cu, Ni, Co, Mn; V = 0; L - NH₃, H₂O; n = 3-4 0.01-0.1, and mass ratio of components in mixture is (1:1)-(9:1), respectively, and zinc or calcium stearate 1-4. Composition can contain also pigment at concentration 4-8 mas. p. Time of viscous-plastic state by plastometer (at initial 30-50 s) after 12 months is 20-40 s, fluidity (at initial 180-190 mm) after 6 months is 160-180 mm, storage time is 6-24 months, range of working temperature is from -60 to +400 C. EFFECT: enhanced quality of composition. 2 cl, 2 tbl
