LIQUID SEAL FOR PNEUMATIC TYRES OF VEHICLES Russian patent published in 2010 - IPC C09K3/10 C08L1/10 B60G17/00 B29C73/16 

FIELD: chemistry.

SUBSTANCE: invention relates to seals designed for repairing pneumatic tyres of any vehicle. Described is a liquid seal for tyres of vehicles which is a suspension in which the liquid phase consists of glycerin and a water-soluble organic polymer, and the solid phase contains an inorganic silicate. The organic water-soluble polymer used is an aqueous solution of KMT Burovoy glue, whose volume ratio to glycerin in the liquid phase equals 0.3:1. The silicate used is aerosil or crushed expanded clay with particle size not greater than 0.5 mm. The seal has density of 1200-1300 kg/m³. Quantitative content of initial components in the seal is as follows, in wt %: glycerin - 73-74, KMT Burovoy glue - 0.4, water - 19-20, aerosol 4-5, expanded clay 3-4.

EFFECT: seal enables to seal punctures of up to 8 mm.
