Problems solved by technology

[0002] As a kind of environmental protection ink, water-based ink composition is widely used in people's life. The commonly used ink is oil-based ink, but oil-based ink often contains a large amount of organic solvents and other harmful components, which are harmful to human body and environment after use, and Usually in the process of color printing, the color of red printing is relatively dull, not bright, and the visual effect of printing is poor. The commonly used water-based ink composition often has unclear effects. At the same time, the commonly used preparation of water-based ink composition The equipment 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 be foaming, which will affect the product quality. Therefore, the existing technology needs further improvement
