Solution Overview
Problem
Existing building boards with insulating coating films containing mixed and dispersed fine ceramic particles exhibit limited thermal insulation effects due to low hollow ratios, and require enhanced weatherability for exterior use.
Innovation Solution
A building board with a base material coated by an insulating film containing organic hollow particles and a water-soluble solvent, topped with a transparent clear coating film, where the insulating film is formed using a paint with a coating film forming material, organic hollow particles, and a water-soluble solvent with a boiling point higher than the drying temperature, ensuring high thermal insulation and weatherability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If fine ceramic particles are mixed and dispersed in a coating film forming material to form an insulating coating film, then thermal insulation effect is intended, but the actual thermal insulation effect is small due to low hollow ratio
Solution Approach 1:
The patent changes the material parameter from inorganic ceramic particles to organic hollow particles, which inherently possess high hollow ratios. This parameter change enables the particles to maintain their hollow structure during coating formation and drying, thereby achieving effective thermal insulation without the manufacturing precision issues associated with ceramic particles.
Solution Approach 2:
The patent uses composite material formulation by combining organic hollow particles with coating film forming materials and water-soluble solvents. This composite approach allows the organic hollow particles to provide thermal insulation while the coating matrix ensures proper adhesion and weatherability, resolving the contradiction between insulation effectiveness and particle structure integrity.
2Loss of energy
If organic hollow particles are used in insulating coating film to improve thermal insulation, then thermal insulation properties are enhanced, but weatherability may be compromised
Solution Approach 1:
The patent creates a composite coating system where organic hollow particles provide thermal insulation and water-soluble solvents ensure proper film formation and adhesion. The coating film forming material provides the matrix that ensures weatherability, while the organic hollow particles contribute high thermal insulation performance, thus resolving the contradiction between insulation and weatherability.
Solution Approach 2:
The water-soluble solvent acts as an intermediary that facilitates homogeneous distribution of organic hollow particles in the coating and ensures proper film formation. This intermediary enables the organic particles to maintain their hollow structure while the coating matrix provides the necessary weatherability for exterior applications.
3Manufacturing precision
If water-soluble solvent is used in insulating paint to form homogeneous coating, then homogeneous thermal insulation effect is achieved, but solvent boiling point must be controlled
Solution Approach 1:
The patent specifies parameter constraints for the water-soluble solvent, particularly the boiling point requirement (higher than coating film drying temperature). This parameter control ensures the solvent remains liquid during application for homogeneous mixing and distribution of organic hollow particles, then evaporates appropriately during drying to form a uniform coating without compromising the hollow particle structure.
