  • Rubber composition, preparation method and vulcanized rubber thereof
    Patent number: 9453122
    Abstract: A rubber composition, preparation method and vulcanized rubber thereof are provided. The rubber composition comprises uncrosslinked rubber and rubber particles having crosslinked structure dispersed therein, wherein the rubber particles having crosslinked structure are synthetic rubber particles and/or natural rubber particles with an average particle size of 20 to 500 nm and a gel content of 60% by weight or higher, and the uncrosslinked rubber is styrene-butadiene rubber, and wherein the weight ratio of the rubber particles having crosslinked structure to the uncrosslinked rubber is 1:99-20:80.
    Type: Grant

  • Modified rubber masterbatch, and rubber composition and vulcanized rubber produced therefrom, and the preparation processes for them
    Patent number: 9290643
    Abstract: The present application relates to a modified rubber masterbatch and preparation method thereof, rubber composition prepared therewith and vulcanized rubber and preparation method thereof. The modified rubber component comprises uncrosslinked rubber and rubber particles having crosslinked structure dispersed therein, wherein the rubber particles having crosslinked structure are synthetic rubber particles and/or natural rubber particles, have an average particle size of 20-500 nm and a gel content of 60% by weight or higher, and wherein the uncrosslinked rubber is styrene-butadiene rubber. The weight ratio of the rubber particles having crosslinked structure to the uncrosslinked rubber is greater than 20:80 and less than or equal to 80:20. The rubber composition comprises a blend of modified rubber component and base rubber, in which the modified rubber masterbatch is present in an amount of 1 to 70 parts by weight, relative to per 100 parts by weight of the base rubber.
