Document Type and Number:
WIPO Patent Application WO/2024/070556
Kind Code:
A1
Abstract:
The present invention provides a millable silicone rubber compound comprising (A) an organopolysiloxane crude rubber, (B) a reinforcing silica that has a specific surface area of 50-450 m2/g, (C) a partial hydrolysate of an organoalkoxysilane represented by general formula (1), and (D) one or more condensation reaction catalysts selected from (D1)-(D3): (D1) an amine compound that is a liquid at 25°C, and has a boiling point of 30-60°C at 1013hPa; (D2) a hexaorganodisilazane represented by general formula (2); and (D3) aqueous ammonia at 1.0-30.0 mass%. Thus provided are a millable silicone rubber compound having a high plasticity even if the millable silicone rubber compound has a relatively low hardness, a millable silicone rubber composition, and a production method for a millable silicone rubber composition.
