Problems solved by technology

[0002] As one of the necessary office supplies for printing documents in people's daily office, ink has a great market demand. The commonly used ink is oily ink, but oily ink often contains a large amount of organic solvents and other harmful components. Harmful to the human body and the environment, and flammable, it is easy to cause a fire. However, the solvent of the water-based ink composition is water, which greatly reduces the damage of the ink to the environment during the printing process. However, the commonly used water-based ink composition, printed out, Its clarity is poor, and the handwriting will appear blurred printing and dyeing. At the same time, the equipment commonly used to prepare water-based ink compositions is a homogenizer, but the homogenizer is not easy to clean, and when there are impurities in the raw materials, the impurities cannot be discharged, and There will also be foaming, which will affect the quality of the product. Therefore, the prior art needs further improvement
