Aerogel Coating Liquid for Complex Surface Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing thermal insulators struggle to form a coating film with sufficient thermal insulation on complex surfaces, requiring separate adherence techniques and often resulting in inadequate insulation.
Innovation Solution
A coating liquid containing aerogel particles, a binder resin, and a fibrous substance with a fiber length of 1.5 mm or more, which improves thermal insulation and dispersibility, allowing for direct application and enhanced coating film strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an aqueous dispersion containing aerogel particles is used as a coating liquid, then the coating liquid can be applied to complex surfaces, but the resulting coating film does not have sufficient thermal insulation
Solution Approach 1:
The patent combines aerogel particles with fibrous substances (having a fiber length of 1.5 mm or more) and binder resins to create a composite coating liquid. This composite structure allows the coating film to maintain both adaptability to complex surfaces and sufficient thermal insulation performance, as the fibrous network provides structural integrity and thermal barrier properties while the aerogel particles contribute to insulation.
2Reliability
If a molded material is produced from aerogel particles, then thermal insulation can be achieved, but it requires separate adherence techniques and cannot conform to complicated surface shapes
Solution Approach 1:
The patent transforms the rigid molded material approach into a flexible coating liquid formulation that can be applied as a thin film conforming to complicated surface shapes. The coating liquid contains aerogel particles, binder resin, and fibrous substances that together create a flexible yet insulating coating that adheres directly to the surface without requiring separate adherence techniques.
3Strength
If the fiber length of the fibrous substance is increased to improve thermal insulation, then coating film strength improves, but dispersibility of the fibrous substance deteriorates
Solution Approach 1:
The patent specifies a particular fiber length parameter (1.5 mm or more) that balances thermal insulation performance and coating film strength while maintaining acceptable dispersibility. This parameter optimization resolves the contradiction by identifying the minimum fiber length required for strength and insulation while avoiding excessive length that would severely impact dispersibility.
