TWO-COMPONENT VIBRATION-ABSORBING MASTIC WITH FOAMED POLYMER GRANULES Russian patent published in 2024 - IPC C08L63/00 C08L23/12

Abstract RU 2813340 C1

FIELD: materials.

SUBSTANCE: invention relates to vibration-absorbing mastics. A two-component vibration-absorbing mastic with foamed polymer granules is proposed for use in the automotive, ship and aircraft industries, in civil and industrial construction, which is a two-component epoxy system consisting of composition “A” and composition “B”, while composition “A” includes epoxy resin, plasticizer, fillers and polypropylene foam granules, and composition “B” is an amine or amidoamine type hardener.

EFFECT: reduced density of a two-component vibration-absorbing mastic ensuring high vibration-damping and sound-proofing properties.
