Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conductive tile flooring materials suffer from limited wear resistance, generating fine wear particles and failing to provide adequate antistatic protection, which can lead to operational failures and electrostatic discharge damage in electronic manufacturing environments.
Innovation Solution
A double-layer laminated conductive tile flooring material with a water-soluble photo-curable antistatic resin composition, containing 5-15% conductive fine particles with carbon nanotubes, 0.1-5% fumed silica, and 10-20% water-soluble epoxy or urethane acrylate, applied as a 3-7 μm thick coating to enhance wear resistance and antistatic properties while maintaining transparency and eco-friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conductive tile flooring materials (rubber or PVC) are used, then antistatic performance is achieved, but wear resistance is poor and fine wear particles are generated
Solution Approach 1:
The patent applies composite materials by combining conductive fine particles (carbon black, carbon nanotubes, or conductive metal oxide particles) with photo-curable resin components (oligomers, monomers, and photopolymerization initiators) to create a coating composition that simultaneously achieves antistatic performance and improved wear resistance when applied to tile flooring surfaces
Solution Approach 2:
The patent employs parameter changes by controlling the particle size of conductive fine particles (1-100 nm diameter), adjusting the molecular weight and functional groups of oligomers and monomers, and optimizing the ratio of components to achieve both antistatic properties and enhanced mechanical durability against wearing
2Reliability
If conductive fine particles are added to photo-curable resin composition, then antistatic property is improved, but transparency is reduced
Solution Approach 1:
The patent applies local quality by using conductive fine particles with specifically controlled small diameters (1-100 nm) that are sufficiently small to minimize light scattering and maintain coating transparency while still providing effective antistatic properties, thus creating localized conductive pathways without compromising overall optical clarity
Solution Approach 2:
The patent addresses transparency by carefully selecting and controlling the concentration of conductive fine particles and their optical properties, ensuring that the coating maintains at least 80% transparency of the underlying tile surface while achieving the required antistatic performance
3Reliability
If carbon black or carbon fiber is used to provide antistatic property, then conductivity is achieved, but wear resistance remains limited and fine particles are generated
Solution Approach 1:
The patent uses composite materials by formulating a coating composition that integrates conductive fine particles within a photo-curable resin matrix, creating a protective layer that provides conductivity while the cured coating structure prevents the generation of fine wear particles during normal use
Solution Approach 2:
The patent applies parameter changes by controlling the particle size, concentration, and distribution of conductive fine particles within the coating, optimizing these parameters to achieve sufficient conductivity while minimizing particle generation through wear of the coated surface
