Transparent Olefin Resin Decorative Sheet Scratch Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative sheets with transparent olefin-based resin layers lack good scratch resistance, post-processing resistance, and high transparency due to inadequate crystallinity and light scattering from large spherulite sizes.
Innovation Solution
Incorporating nucleating agent vesicles with a single-layer outer membrane into the transparent olefin-based resin, produced via the supercritical reverse phase evaporation method, to enhance the Martens hardness of the resin layer to 40 N/mm² or higher, thereby improving crystallinity and reducing spherulite size for better scratch resistance and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a transparent olefin-based resin is used for the decorative sheet, then chemical environmental burden is reduced, but scratch resistance and post-processing resistance are insufficient
Solution Approach 1:
The patent changes the crystallinity parameter of the olefin-based resin by adding a nucleating agent, transforming it from a low-crystallinity state to a high-crystallinity state (50% or more). This parameter change simultaneously improves scratch resistance and post-processing resistance while maintaining the chemical environmental benefits of using olefin-based resin instead of PVC
Solution Approach 2:
The patent creates a composite material system by combining olefin-based resin with a nucleating agent. This composite structure enables the resin to achieve high crystallinity and improved mechanical properties while maintaining its inherent chemical stability and environmental advantages
