Abstract

The invention belongs to the technical field of ink emulsion, and in particular relates to a special water-based emulsion for plastic film ink and a preparation method thereof. The water-based emulsion includes the following raw materials in parts by weight: Phase A: 300-400 parts of solid resin, 200-250 parts of deionized water; Phase B: 1-10 parts of reactive emulsifier, 5-15 parts of deionized water; Phase C: 0.5-1.5 parts of initiator, 15-25 parts of deionized water; Phase D: 6-17 parts of crosslinking agent, 10 parts of water ‑20 parts; E phase: 3‑10 parts of crosslinking agent, 25‑35 parts of water; M phase: 310‑370 parts of mixed reaction agent. The water-based emulsion of the present invention has excellent adhesion to non-absorbent substrates PE, BOPP, and PET; the preparation method is easy to operate, and the prepared water-based emulsion has excellent adhesion to films by strictly controlling the addition time and reaction temperature of each raw material. Adhesion, chemical resistance and physical resistance.

Description

technical field [0001] The invention relates to the technical field of ink emulsions, in particular to a special water-based emulsion for plastic film inks and a preparation method thereof. Background technique [0002] Since water-based ink does not contain volatile organic compounds, it greatly reduces the emission of volatile organic compounds (VOC), thereby reducing air pollution, improving the environment and overall environmental quality of printing operators, and benefiting the health of employees. In addition, it can not only reduce fire hazards and hidden dangers caused by static electricity and flammable solvents, but also reduce residual toxicity on the printing surface and facilitate cleaning of printing equipment. Therefore, water-based inks have emerged to solve the problems of volatile organic compound emissions caused by solvent-based inks. They have outstanding environmental protection advantages and are considered by the industry to be one of the environmen...
