RUBBER COMPOSITION FOR MAGNESIUM HYDROXIDE WAFER-REINFORCED TYRE

摘要

The invention concerns a rubber composition with enhanced vulcanizing kinetics, useful in particular for making tyres or semi-finished products for tyres, based on at least one diene elastomer, a reinforcing filler and a coupling agent binding the filler and the elastomer. The invention is characterized in that said reinforcing filler comprises synthetic magnesium hydroxide Mg(OH)₂ wafers, coated with silica. The invention also concerns the use of such a composition for making rubber articles, in particular tyres or rubber semi-finished products for said tyres, in particular running treads. The invention also concerns, per se, said synthetic magnesium hydroxide in the form of wafers coated with silica, as well as its use as reinforcing filler, in particular in a diene elastomer matrix.
