Problem
Ink compositions stored in plastic film pouches suffer from insufficient storage stability, leading to ink head clogging during high-speed and high-definition printing due to polyolefin elution and aggregation.
Innovation Solution
An ink composition containing a polymerizable compound, polyolefin, and a polyolefin aggregation inhibitor, such as nanoparticles and/or a polymer dispersant, is developed to suppress polyolefin aggregation and enhance storage stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ink composition is stored in a pouch including a plastic film, then the ink can be provided in an environmentally friendly and safe form, but the storage stability of the ink is insufficient and polyolefin aggregation occurs
Solution Approach 1:
A silane-modified polyolefin aggregation inhibitor is introduced as an intermediary substance between the ink composition and the pouch material. This inhibitor specifically binds to polyolefin molecules through silane groups, preventing their aggregation while being compatible with the ink formulation. The inhibitor acts as a mediating agent that addresses the harmful interaction between the ink and pouch material.
Solution Approach 2:
The chemical structure of the aggregation inhibitor is modified by introducing silane groups, which changes its physical and chemical parameters. This modification enhances the inhibitor's ability to interact with polyolefin molecules and improves its effectiveness in preventing aggregation. The parameter change in the inhibitor's molecular structure directly addresses the storage stability issue.
2Manufacturing precision
If high-speed and high-definition printing conditions are used, then printing quality is improved, but ink head clogging occurs due to polyolefin aggregation
Solution Approach 1:
The polyolefin aggregation inhibitor is pre-added to the ink composition before printing operations. This preliminary action ensures that polyolefin molecules are already protected against aggregation before the ink reaches the ink head, preventing clogging issues during high-speed and high-definition printing operations.
Solution Approach 2:
The silane-modified aggregation inhibitor serves as a protective intermediary that remains active during printing operations. It continuously prevents polyolefin aggregation in the ink, ensuring reliable ink flow to the ink head even under demanding high-speed and high-definition printing conditions.
