Description

technical field [0001] The invention belongs to the technical field of pyrolysis carbon black manufacture and application, in particular to a novel modified pyrolysis carbon black and a preparation method thereof. Background technique [0002] Along with the continuous increase of the current automobile usage, the amount of tires is increasing, resulting in a large accumulation of waste tires, which in turn has brought serious "black pollution" problems. At present, pyrolysis technology is the ultimate means to realize the complete recycling of waste tires, which can be used to prepare waste tires into oil, carbon black and steel wire. However, the traditional pyrolysis technology still has the defects of high energy consumption, high cost, low yield and unsatisfactory quality of carbon black products. [0003] Therefore, how to develop a new carbon black preparation method with simple operation, low cost and ideal carbon black quality is the key to solving the above proble...
