Abstract: Preparation of silicate and/or oxygenic filler-containing rubber powder or granulate, based on aqueous rubber emulsion or latex, involves suspension of silicate and/or filler, polysiloxane hydrophobizing agent and nonionic surfactant in water, adjustment of the pH to 2.5-7, separation of the deposited rubber powder from the solid particles, and drying the powdered or granulated product to a moisture content of less than 3%. A process for preparation of silicate and/or oxygenic filler-containing rubber powder or granulate based on aqueous rubber emulsion or latexes involves: (a) suspension of a silicate and/or oxygenic filler, polysiloxane hydrophobizing agent(s) (in amount 0.5-7% relative to the filler) and nonionic surfactant(s) (in amount 0.1-2% relative to the filler) at 10-60 degrees C in water, giving a suspension of density 0.5-5%, (b) addition of the rubber latex emulsion to the filler suspension with stirring, (c) adjustment of the pH of the aqueous mixture with an acid, preferably sulfuric acid or aluminum sulfate to a pH of 2.5-7, (d) separation of the deposited rubber powder from the process water by, for example, solid/liquid separation of the solid particles, (e) molding of the filter cake, and (f) drying of the powdered or granulated product to an end moisture content of less than 3%.

Abstract: Continuous production of filled rubber granules comprises introducing an aqueous filler composition and a rubber latex through separate inlets into a reactor with a high-speed stirrer and coagulating the latex by lowering the pH and/or adding a water-soluble Group IIa, IIb, IIIa or VIII metal salt.

Abstract: The invention provides a method for the preparation of vulcanisable rubber mixtures containing silicas and organosilane compounds, and these mixtures. The organosilane compounds are of the general formula: (C1-8 alkly -O) 3Si (CH2)3SCN. The mixtures when vulcanised provide mouldings and structural components for tyres having decreased abrasion.

Abstract: A precipitate of silica having the following physicochemical parameters: BET surface area: from 35 to 350 m /g Ratio of BET/CTAB surface area: from 0.8 to 1.1 Pore volume PV: from 1.6 to 3.4 ml/g Silanol group density (V2 = consumption of NaOH): from 6 to 20 ml Mean aggregate size: from 250 to 1500 nm CTAB surface area: from 30 to 350 m /g DBP number: from 150 to 300 ml/100 g V2/V1 according to Hg porosimetry: from 0.19 to 0.46 DBP/CTAB: from 1.2 to 2.4 is prepared by reacting alkali metal silicate with mineral acids at temperatures of from 60 to 95 DEG C while maintaining a pH of from 7.5 to 10.5 with continuous stirring, continuing the reaction to a solids concentration in the precipitate suspension of from 80 to 120 g/l, adjusting the pH to a value equal to or less than 5, filtering off, washing, drying and, if desired, milling or granulating the precipitated silica. The precipitated silica is used as filler in vulcanisable rubber mixtures and vulcanisates.
