METHOD FOR THE PREPARATION OF RUBBER COMPOUNDS FOR POLYMER PRODUCTS COMPRISING A NATURAL COMPOSITION WITH AN ANTIOXIDANT ACTIVITY

摘要

A method for preparing a rubber compound comprising a grinding step to grind food waste comprising chemicals with an antioxidant activity, whose structure comprises hydroxyl groups and conjugated double bonds, and a mixing step, during which a powder obtained from said grinding step is mixed with a polymer base with a cross-linkable unsaturated chain of the compound, and a further and subsequent mixing step wherein the compound being prepared is mixed with a vulcanization system.
