Intumescent Gasket for Dry Lining Box Fire and Acoustic Sealing
Solution Overview
Problem
Conventional intumescent gaskets for dry lining boxes lack both fire protection and acoustic properties, failing to provide comprehensive safety and noise reduction in fire scenarios.
Innovation Solution
A gasket comprising a sponge material base with upstanding walls, where an intumescent material layer is applied and retained using an adhesive, offering both fire protection and acoustic insulation, with the ability to expand and maintain the dry lining box's position during a fire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional intumescent gaskets are used, then fire protection is provided, but acoustic properties are lacking
Solution Approach 1:
The gasket combines sponge material (providing acoustic insulation) with intumescent material (providing fire protection) into a single composite structure. The sponge material forms the base structure while the intumescent material is applied as a coating or impregnated layer, creating a multi-functional composite that simultaneously addresses both acoustic and fire safety requirements.
2Object-affected harmful factors
If sponge material is used for acoustic protection, then acoustic properties are improved, but fire protection capability is reduced
Solution Approach 1:
Different regions of the gasket have different material properties optimized for their specific functions. The inner core uses sponge material optimized for acoustic absorption, while the outer surface or impregnated layers use intumescent material optimized for fire protection. This local differentiation allows each material to perform its primary function effectively.
3Device complexity
If a single material is used for the gasket, then device complexity is reduced, but dual functionality (fire and acoustic protection) cannot be achieved
Solution Approach 1:
The patent merges two separate functional requirements (acoustic insulation and fire protection) into a single integrated gasket component. The sponge material provides the structural base for acoustic protection, while the intumescent material layer provides fire protection. Both materials are combined in one manufactured component that performs both functions simultaneously, eliminating the need for separate acoustic and fire protection elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The gasket effectively provides fire protection and acoustic insulation, ensuring the dry lining box's integrity and safety by expanding to form a seal during a fire while maintaining acoustic properties.
Implementation Method 1
the intumescent material rapidly expands to retain the dry lining box in place
Implementation Method 2
The intumescent material layer 8 is retained against the base 4 using suitable adhesive
Implementation Method 3
The sponge material of the base 4 and side walls 6 of the gasket 2 provide acoustic protection to the dry lining box
