RUBBER COMPOUND FOR MANUFACTURING ACOUSTIC LAYER OF A COATING Russian patent published in 2005 - IPC

Abstract RU 2258718 C1

FIELD: rubber industry.

SUBSTANCE: invention relates to manufacture of multilayer sound-absorbing polymer coatings. Rubber compound of invention comprises, wt parts: cis-isoprene rubber SKI-3 100, thiuram 1.5-2.0, vulcanization accelerators altax 1.5-2.0 and captax 1.2-1.5, anti-ageing agent Naftam-2 1.2-1.5, zinc oxide 10-12, stearic acid 1.5-2.0, and carbon black T-900 12-20. Such rubber compound allows formation of acoustic layer of coating, which is operable within sound frequency range from 5 to 1000 Hz and has dynamic shear modulus between 0.5 and 1.0 MPa.

EFFECT: improved performance characteristics of coating.
