The present invention provides a modified carbon black, with 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 serves as a grafting group; and an active group on the other end serves as a crosslink 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 agent i.e., thioether and thiuram compounds for the described product. The modified carbon black could be crosslinked together with tire rubber. If the carbon black does not move, the rubber also does not move, thereby improving wet grip 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.
本发明提供了一种改性碳黑,其表面接枝有不饱和偶联剂。偶联剂一端的不饱和双键被接枝在碳黑表面上,作为接枝基团;另一端的活性基团作为交联基团,将来与橡胶保持交联功能。至少选择一种偶联剂,包括含硫化合物、含卤化合物、含氮化合物、多不饱和化合物。本发明还提供了所述产品的能量球磨制备方法,并提供了两种含硫不饱和偶联剂即硫醚和硫脲化合物的配方和制备方法。改性碳黑可以与轮胎橡胶交联。如果碳黑不动,橡胶也不动,从而提高湿地抓地力和行车安全性。如果橡胶移动,碳黑也移动,从而减少内部摩擦和节省油耗,减少轮胎产生的热量并延长轮胎使用寿命。
