VIBRATION ABSORBING PASTE Russian patent published in 2014 - IPC C09D131/04 C09D5/02 

FIELD: chemistry.

SUBSTANCE: invention relates to vibration absorbing coating compositions, particularly internal coatings of ship space, rail cars, pipelines, protective casings, protection of the inside of vehicles from vibrations of components and engine noise. The vibration absorbing coating can also be used in aviation, aerospace industry, construction and mechanical engineering. The vibration absorbing paste contains crystalline graphite, an aqueous polymer dispersion based on vinyl acetate with a dry residue of 51-55 wt %, a plasticiser, a density regulator, cellulose powder, sodium alkylbenzene sulphonate surfactant, a fire retardant, tetramethylthiuram disulphide, chalk and water.

EFFECT: low density of the vibration absorbing paste, high coefficient of mechanical losses of damping coatings made therefrom, easier application of the paste using a palette knife and by spraying, with the same viscosity in the mobility range of the paste of 80-100 mm.
