Solution Overview
Problem
Conventional flame retardant labels for electrical equipment face challenges in maintaining effective flame retardancy while ensuring good adhesion, preventing air bubble entrapment, and controlling thickness, often leading to increased production costs and compromised performance.
Innovation Solution
A flame retardant label comprising a coating layer with a first base polymer, crosslinker, and flame retardant agent, a film layer, and an adhesive layer with a second base polymer, flame retardant agent, tackifier, and crosslinker, featuring air egress channels to prevent bubble formation and improve adhesion, using specific polymer compositions and crosslinkers to enhance performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flame retardants are added to improve flame retardant properties, then flame retardancy is improved, but adhesion performance deteriorates
Solution Approach 1:
The label is divided into multiple functional layers: a base layer providing adhesion, a flame retardant layer containing flame retardant agents, and a topcoat layer. This segmentation allows each layer to optimize its specific function without compromising others, resolving the contradiction between flame retardancy and adhesion performance.
Solution Approach 2:
The patent uses composite material structures combining different polymers and flame retardant agents in specific layers. The base layer uses adhesion-promoting materials while the flame retardant layer uses intumescent or halogen-free compounds, creating a composite structure that achieves both good adhesion and effective flame retardancy simultaneously.
2Reliability
If the thickness of the label is increased to improve flame retardancy and adhesion, then flame retardancy and adhesion are improved, but production cost increases and label application becomes inconvenient
Solution Approach 1:
The patent employs thin-film technology to create a flame retardant label with optimized thickness. The multi-layer structure achieves effective flame retardancy and adhesion performance in a thin profile, reducing material consumption and production costs while maintaining flexibility for easy application on various substrates.
3Ease of operation
If conventional label application is used, then application process is simple, but air bubbles are trapped during application
Solution Approach 1:
The patent incorporates a microporous structure in one of the layers that allows air bubbles to escape during the labeling process. This porous pathway enables simple application without trapping air bubbles, maintaining both ease of operation and product reliability by preventing bubble formation.
