VIBRATION-ABSORBING MASTIC Russian patent published in 2019 - IPC C08L95/00 C08L23/22 C08L31/04 C08K3/04 C08K3/26

Abstract RU 2705961 C1

FIELD: manufacturing technology.

SUBSTANCE: invention relates to compositions for vibration-absorbing coatings used in car-, auto industry, shipbuilding, aviation, machine building and other fields of engineering, where vibration protection is required, in particular to compositions of polymer vibration-absorbing mastic of non-drying type intended for operation at temperatures from minus 50 °C to plus 120 °C. Vibration-absorbing mastic contains butyl rubber BK 1675N, oil bitumen BN 90/10, industrial oil grade I-20A, chalk, technical carbon and ethylene vinyl acetate are fillers.

EFFECT: technical result consists in improvement of vibration damping properties, expansion of temperature of operation of polymer composition in range from minus 40 °C to plus 80 °C, based on the polymer composition of the vibration-absorbing mastic, simplifying the mounting of the material on different coatings.
