Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional decorative members face issues with ink adhesion to base layers, leading to poor print quality and emission of harmful materials like formaldehyde, which can harm human health.
Innovation Solution
A decorative member with an ink-receiving layer composed of an acrylic emulsion, a metal salt, and an inorganic particle, applied between the base layer and the printing layer, ensuring excellent printability and durability while preventing formaldehyde emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a polyolefin resin is stacked on both sides of the paper base layer, then the base layer gains protection and durability, but the ink adhesion deteriorates and the printing layer cannot be accurately formed
Solution Approach 1:
An ink-receiving layer is introduced as an intermediary between the polyolefin resin-coated base layer and the printing layer. This intermediate layer has specific surface properties that enable it to adhere to both the polyolefin resin and the printing ink, resolving the adhesion problem caused by the polyolefin coating.
Solution Approach 2:
The base layer structure is segmented into multiple functional layers: the original paper base layer, the polyolefin resin protective layer, the newly added ink-receiving layer, and the printing layer. This segmentation allows each layer to perform its specific function without interfering with others.
2Manufacturing precision
If conventional materials are used in the ink-receiving layer, then the printing layer can be formed, but harmful materials such as formaldehyde are emitted
Solution Approach 1:
The chemical composition parameters of the ink-receiving layer are changed by using specific polymers with controlled molecular structures and compositions that do not contain or generate formaldehyde, while maintaining the necessary functional properties for ink reception and adhesion.
Solution Approach 2:
The ink-receiving layer is formulated as a composite material system comprising specific polymers, plasticizers, and other additives that work together to provide the required functionality without emitting harmful substances. The composite structure allows optimization of both performance and safety.
