Abstract

The invention relates to the technical field of tire packing preparation and in particular to a white carbon black carbon nanotube composition as well as a gas-phase in-situ preparation process and application thereof. The process comprises the following steps: (1) performing preheating treatment on a silicon halogen compound, hydrogen, air, ferrocene and a carbon source gas; (2) performing pyrohydrolysis and chemical vapor deposition reactions to form a composition; (3) performing cooling in a cooling tank; and (4) performing wet-method pelletizing, and performing screening and drying. The prepared white carbon black carbon nanotube composition can be applied to the field of tire manufacturing. The process provided by the invention is simple and stable and convenient in operation, and conventional white carbon black production devices and equipment do not need to be changed; and by adopting the white carbon black carbon nanotube composition product provided by the invention, the problem of electrostatic accumulation of pure white carbon black as green packing in a tire can be effectively alleviated, the reinforcing capability and the security of the tire can be improved, and the market competitiveness of the product can be improved.

Description

technical field [0001] The invention relates to the technical field of tire filler preparation, in particular to a white carbon black carbon nanotube compound and its gas-phase in-situ preparation process and application. Background technique [0002] Fumed silica is a high-tech inorganic fine chemical product, which has a high purity of more than 99.8% and a tendency to form chains. In addition, it also has unusual particle characteristics, that is, it has an extremely small particle size and a huge specific surface area. (100-400m 2 / g). Based on the above characteristics, fumed silica exhibits excellent reinforcement, thickening, thixotropy, extinction, dispersion, insulation and anti-adhesive properties, so it is widely used in coatings, adhesives, cosmetics, Ink, plastic, medicine, pesticide and sealant and many other industrial fields, the development prospect is very broad. In recent years, silica has been used as a reinforcing agent in rubber tire formulations, an...
