Abstract (en)
[origin: CA3184972A1] The invention provides modified silicas having the following physicochemical parameters: CTABmod < 200 m /g, BETMP 50-500 m /g, CTABmod - BETMP < 0 m /g, carbon content > 0.5% by weight, modemod from CPS particle size determination > 50 nm, d75mod from CPS particle size determination 20-150 nm, Rmin from Hg pore size determination, pressurized < 10 nm, sulfur content ? 1.50% by weight. The modified silicas are prepared by mixing a silica with at least one additive selected from the group of aqueous sulfur-containing alkoxysilane emulsion, polysiloxane, mixture of sulfur-containing alkoxysilane and polysiloxane, or mixture of sulfur-containing alkoxysilane and anionic polyether in the intake of the drying unit, and then supplying the mixture to the drying unit. The modified silicas are used for production of pneumatic tyres, cable sheaths, hoses, drive belts, conveyor belts, roll coverings, tyres, footwear soles, gasket elements and damping elements.
