Sealing Laminate Structure for Higher Flame Retardancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silicone rubber materials for sealing applications lack sufficient flame retardancy, necessitating an enhancement in their fire-resistant properties.
Innovation Solution
A laminate for sealing materials comprising a first layer of flame-retardant silicone rubber compound and a second layer with a fiber-based flame retardant, where the organic component in the second layer is limited to 0-10% by weight, enhancing the overall flame retardancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flame-retardant layer is disposed on a substrate to impart flame retardancy, then flame retardancy is improved, but the organic component content increases which may reduce effectiveness
Solution Approach 1:
The patent applies parameter changes by precisely controlling the organic component content in the second layer to be 0 to 10% by weight. This quantitative parameter optimization ensures sufficient flame retardancy while minimizing organic content that could interfere with the flame-retardant effect. The first layer uses a flame-retardant silicone rubber compound with specific compositional parameters to achieve balanced performance.
Solution Approach 2:
The patent employs composite materials by creating a two-layer laminate structure where the first layer contains flame-retardant silicone rubber compound and the second layer contains fiber-based flame retardant with controlled organic content (0-10% by weight). This composite structure combines the advantages of both layers: the silicone rubber provides flexibility and base flame retardancy, while the fiber-based layer with minimal organic content provides enhanced fire-resistant properties without the drawbacks of high organic content.
2Ease of manufacture
If fiber-based flame retardant is used with high organic component content, then manufacturing is easier, but flame retardancy is reduced
Solution Approach 1:
The patent optimizes the organic component content parameter to 0-10% by weight in the second layer, finding the optimal balance between manufacturability and flame retardancy. This parameter control ensures that the fiber-based flame retardant maintains its structural integrity and ease of processing while achieving maximum fire-resistant effectiveness.
Solution Approach 2:
The patent applies local quality by creating distinct functional zones in the two-layer structure. The first layer is optimized for flexibility and base flame retardancy using flame-retardant silicone rubber, while the second layer is optimized for maximum fire resistance with controlled organic content (0-10%). Each layer has locally optimized properties that together solve the contradiction between ease of manufacture and flame retardancy.
