Latest Patents

Ralf Rausch's latest patents include advancements in precipitated silicas. One of his notable inventions is a rubber composition that comprises a precipitated silica with specific physico-chemical properties. This silica is produced by reacting alkali silicate with mineral acids at temperatures ranging from 60°C to 95°C while maintaining a pH of 7.5 to 10.5. The process involves continuous stirring and further reaction until a solids concentration of 90 g/l to 120 g/l is achieved. The pH is then adjusted to a value of less than or equal to 5, followed by filtering, washing, drying, and optionally grinding or granulating the precipitated silica. This innovative material is utilized as a filler in vulcanizable rubber compounds and vulcanizates.
