Abstract

A filler for natural rubber comprises a light, highly voluminous alkaline earth metal silicate or a silicate or silica of similar properties obtained therefrom by acid treatment, the first said silicate having been prepared by reacting a natural material consisting mainly or completely of silica with an amount of alkaline earth metal hydroxide, e.g. calcium hydroxide, in aqueous suspension at elevated temperature and pressure. (see Group III).ALSO:Natural material consisting mainly or almost completely of silica, such as sand and kieselguhr, are treated in aqueous suspension at elevated pressure and at least 150 DEG C. with an amount of alkaline earth metal hydroxide e.g. calcium hydroxide greater than the equimolar quantity based on the silica content of said material to obtain a light, highly voluminous alkaline earth metal silicate. The liquid:solid ratio in the suspension is preferably not greater than 1:8 and the silica:alkaline earth metal hydroxide ratio is preferably 1:1.1 to 1:1.3. In the example, a temperature of 200 DEG C. and a pressure of 18-19 at. are employed. By treating the product with an acid or a medium with an acid reaction, voluminous acid silicates or silica are produced.
