Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-skid and wear-resistant floor coatings face challenges in being easy to clean and maintain, especially in high-traffic and decorative areas like ships, trains, and stadiums, due to the accumulation of pollutants and reduced anti-fouling performance from traditional fillers.
Innovation Solution
A novel easy-to-clean antiskid wear-resistant floor coating composed of a coating component and a curing agent component, utilizing elastic polyurethane resin with alicyclic structure, polyaspartic acid ester, and polyether polyol, along with additives like hydrophilic anti-staining agents and elastic microspheres, which improves wear resistance, friction coefficient, and ease of cleaning by preventing dirt accumulation and enhancing surface roughness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional wear-resistant fillers (SiC, Al2O3, corundum sand, quartz sand, hollow or solid glass beads) are added to improve antiskid and wear-resistant properties, then the friction coefficient and roughness increase, but the fillers form dead corners that cause accumulation of pollutants and are difficult to remove, resulting in the coating not being easy to clean and anti-fouling performance is reduced
Solution Approach 1:
The patent changes the shape parameter of the filler from traditional irregular or spherical forms to specific geometric shapes (square, rectangular, triangular, or pyramidal cross-sections with rounded corners). This parameter change eliminates dead corners while maintaining antiskid properties, allowing the coating to be easy to clean while preserving wear resistance
Solution Approach 2:
The patent uses a composite filler system combining inorganic fillers (calcium carbonate, barium sulfate, titanium dioxide) with specifically shaped elastic microspheres. This composite approach provides both the wear resistance from the inorganic fillers and the easy-to-clean property from the rounded-corner geometric shapes, resolving the contradiction between durability and maintainability
2Reliability
If anti-skid fillers are added to improve roughness and friction coefficient, then antiskid performance is enhanced, but the coating surface becomes difficult to maintain and clean
Solution Approach 1:
The patent modifies the geometric parameters of the filler particles by specifying square, rectangular, triangular, or pyramidal cross-sections with rounded corners. This parameter change maintains the friction coefficient needed for anti-skid performance while eliminating the dead corners that trap pollutants, thereby improving ease of maintenance without sacrificing safety
3Strength
If polyurethane resin is used for excellent flexibility, impact resistance and wear resistance, then the coating has good mechanical properties, but the coating needs to meet high decorative requirements and be easy to clean for applications like ships, trains, airplanes, and stadiums
Solution Approach 1:
The patent changes the surface geometry parameter of the filler particles to rounded corners on geometric shapes, which prevents pollutant accumulation while maintaining the mechanical properties of the polyurethane resin coating. This allows the coating to simultaneously achieve impact resistance and resistance to pollutant accumulation in high-traffic areas
Solution Approach 2:
The patent creates a composite coating system combining polyurethane resin with specifically shaped inorganic fillers and elastic microspheres. This composite structure provides the flexibility and impact resistance of polyurethane while the shaped fillers prevent dead corners, resolving the contradiction between mechanical durability and resistance to contamination
