Title:
MODIFIED CARBON BLACK AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/051683
Kind Code:
A1
Abstract:
The present invention provides a modified carbon black, an unsaturated coupling agent being grafted on the surface thereof. An unsaturated double bond on one end of the coupling agent is grafted on the surface of the carbon black to serve as a grafting group; and an active group on the other end serves as a crosslinking group to retain a crosslinking function with rubber in the future. At least one coupling agent is selected from sulfur-containing compound, halogen-containing compound, nitrogen-containing compound, polyunsaturated compound. The present invention also provides an energy ball milling preparation method for the described product, and provides the formulas and preparation method of two kinds of sulfur-containing unsaturated coupling agents-- thioethers and thiurams dedicated for the described product. The modified carbon black is crosslinked together with tire rubber. If the carbon black does not move, the rubber also does not move, thereby improving wet-skid resistance and driving safety. If the rubber moves, the carbon black also move, thereby reducing internal friction and saving oil, and reducing heat generated from the tire and prolonging the service life of the tire.
