ADHESIVE COMPOSITION Russian patent published in 2000 - IPC

FIELD: chemical industry. SUBSTANCE: described is adhesive composition for fixing solid fuel based on urethane rubber and rubber of various types with rocket engine body. Composition comprises epoxidized low-molecular rubber as binder, and hardener. Composition comprises, as binder, lower molecular rubber with molecular weight of 2500-5000 containing 2.8-4.2% of epoxy groups, as hardener, di-N-oxide-1,3-dinitrile- 2,4,6-triethylbenzene, and as active filler rosin modified diphenylolpropane-formaldehyde condensation product, and as solvent, ethyl acetate, ratios of components, being as follows wt parts: low molecular rubber with molecular weight of 2500-5000 containing 2.8- 4.2 % of epoxy groups, 40-60; resin modified diphenylolpropane-formaldehyde condensation product, 2.5- 5.5; di-N-oxide 1,3-dinitrile-2,4,6-triethylbenzene, 1.5- 6.0; ethyl acetate, 40-60. EFFECT: lower hardening temperature of adhesive composition based on epoxidated low molecular rubber. 6 ex, 8 tbl
