Water repellent composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water-repellent textile products suffer from reduced reliability due to seam sliding and poor storage stability, especially when combined with hydrophobic and hydrophilic particles, which can precipitate and affect durability.
Innovation Solution
A water-repellent composition comprising a hydrocarbon-based resin with a hydrocarbon group of 5 to 40 carbon atoms and a hydrophilic particle, which provides both water-repellency and slip resistance while maintaining storage stability, potentially including additional components like silicone, wax, and surfactants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrophobic and hydrophilic particles are combined in conventional water-repellent compositions, then water-repellency is improved, but storage stability deteriorates due to precipitation
Solution Approach 1:
The patent introduces a specific binder resin as an intermediary substance that mediates between hydrophobic particles and hydrophilic particles. This binder resin contains both hydrophobic groups (to bond with hydrophobic particles) and hydrophilic groups (to bond with hydrophilic particles), enabling stable combination of the two particle types without precipitation while maintaining water-repellent functionality.
