The invention provides a degradable water-based ink for biodegradable plastics, a preparation method and application thereof. The raw materials for preparing the water-based ink include: pullulan modified liquid, polyvinyl alcohol resin liquid, water-based polyamide, dispersant, environmental pigment powder, polyethylene wax paste, water-based plasticizer, alcohol solvent and water. The water-based ink is suitable for printing on various types of biodegradable plastics, and its printing leveling, adhesion, water resistance and other indicators all meet the standards, and does not cause damage to degraded plastics, and has the performance of composting with biodegradable materials. It becomes a fertilizer, and no heavy metals enter the soil without side effects. |
