Production process of special white carbon black for ink

The invention relates to a production process of white carbon black special for ink. The production process comprises the following steps: a) synthetic reaction, b) filtering and pulping treatment, c) drying treatment, d) modifier treatment and e) crushing treatment. The white carbon black special for the printing ink prepared by the production process is high in quality and designed for the printing ink, the hydrophobicity of the white carbon black special for the printing ink can reach 40-50, the physical and chemical properties of the printing ink can be effectively improved when the white carbon black special for the printing ink is added into the printing ink, and the white carbon black has a good three-dimensional network structure, a large specific surface area and high activity and can form a network structure when the printing ink is dried; therefore, the storage stability, printing adaptability and other properties of the ink are improved; meanwhile, the strength and smoothness of the ink are improv
