Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing inks do not provide biodegradability for the print films they form, leading to potential environmental issues.
Innovation Solution
A printing ink containing a fixing agent with a peptide polymer, which can be a polypeptide chain, optionally with a modifying group, and a coloring agent, is used to form a print film on various base materials, allowing for biodegradability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional fixing agents (synthetic resins) are used in printing ink, then the print film can be formed with good film integrity and adhesion, but the printed material lacks biodegradability
Solution Approach 1:
The fixing agent is designed as a composite material combining a peptide polymer (for biodegradability) with a synthetic resin component (for film integrity and adhesion). This composite structure allows the print film to maintain mechanical strength while being biodegradable, as the synthetic resin provides structural support and the peptide polymer enables degradation after use.
Solution Approach 2:
The invention changes the chemical composition parameters of the fixing agent by incorporating peptide polymers with specific amino acid sequences and molecular weights. By adjusting the peptide polymer content, molecular weight, and amino acid composition, the balance between biodegradability and film integrity can be optimized to achieve both environmental friendliness and functional performance.
2Object-affected harmful factors
If peptide polymer is used as fixing agent to achieve biodegradability, then environmental impact is reduced, but film strength and adhesion may be compromised
Solution Approach 1:
The fixing agent combines peptide polymer with synthetic resin components to create a composite material that achieves both biodegradability and film strength. The peptide polymer provides the biodegradable matrix while the synthetic resin reinforces the film structure, ensuring adequate mechanical properties for handling and application.
Solution Approach 2:
The peptide polymer and synthetic resin components are distributed in specific ratios and configurations within the fixing agent to optimize local properties. The peptide polymer provides biodegradability in specific regions while synthetic resin concentrates in areas requiring enhanced strength, achieving both environmental friendliness and mechanical performance through spatial differentiation of material properties.
