Epoxy Cast Floor Composition for Chemical and Mechanical Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cast floors in hospitals and chemical plants lack sufficient chemical and mechanical resistance, leading to decreased skid resistance and increased risk of slipping due to contamination and chemical exposure, compromising safety and durability.
Innovation Solution
A composition comprising 20-70 wt% epoxy resin with specific additives such as benzyl alcohol, salicylic acid, cyclo-aliphatic polyamides, and fillers, which forms a strongly cross-linked surface with enhanced chemical and mechanical resistance, maintaining skid resistance and preventing staining even after exposure to chemicals like paraffin wax.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a smooth surface is provided to meet aesthetic requirements, then the floor appearance is improved, but skid resistance deteriorates
Solution Approach 1:
The patent applies different surface treatments to different regions: the main floor surface maintains smoothness for aesthetics, while specific localized areas incorporate anti-slip aggregates or textures to provide skid resistance where needed, such as near sinks, toilets, or high-traffic zones.
Solution Approach 2:
The patent introduces a third dimension by adding a coating layer or surface treatment that creates texture and roughness on top of the smooth base surface, allowing the floor to simultaneously achieve aesthetic smoothness and functional skid resistance through layered structure.
2Reliability
If a thin coating layer is applied to provide skid resistance, then safety is improved, but mechanical vulnerability increases
Solution Approach 1:
The patent combines multiple materials in a composite structure: a durable base coating layer providing mechanical strength and chemical resistance, combined with a thinner anti-slip surface layer providing skid resistance, creating a synergistic composite that achieves both protection and safety without excessive vulnerability.
Solution Approach 2:
The patent applies a protective base coating layer first before adding the anti-slip surface treatment, establishing a strong mechanical foundation in advance that protects the underlying floor from damage while allowing the skid-resistant layer to be applied on top.
3Productivity
If acrylic-based cast floors are used for quick installation, then productivity is improved, but chemical and mechanical resistance deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters of the cast floor material, transitioning from pure acrylic to a formulation incorporating epoxy resins, polyamides, or other polymers with superior chemical and mechanical resistance properties, while maintaining acceptable installation speeds through optimized mixing and curing parameters.
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 composition provides a cast floor with significantly improved chemical and mechanical resistance, maintaining skid resistance and preventing staining, with an SRT value approximately 100% higher than standard acrylic floors, ensuring safer and more durable surfaces.
Implementation Method 1
The more crosslinks are produced, the stiffer/rigid the polymer structure of the floor will be with the associated mechanical properties
Implementation Method 2
the floor shows reduced swelling, discoloration, deposition and degradation after at least 8 hours of exposure to corroded acids and vinegar
