Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Formulating a hard surface treatment composition that can produce hydrophobic coatings on hard surfaces in the presence of cleansing surfactants and high water concentrations, which is challenging due to the difficulty in achieving high contact angles and low sliding angles against water.
Innovation Solution
A composition comprising non-ionic surfactant and non-volatile aminosilicone emulsified by an emulsifier, where the non-volatile aminosilicone accounts for at least 15% of the total non-volatile silicones, and the emulsifier is different from the non-ionic surfactant, with a pH value of no greater than 11.8, applied to the surface to form a hydrophobic coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cleansing surfactant and high water concentrations are used in the composition, then cleaning capability is improved, but the ability to form hydrophobic coating deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the composition by specifying precise pH ranges (pH ≤ 11.8, and pH ≤ 8.5 when aminoethylaminopropyl poly(dimethylsiloxane) is used) and silicones composition (at least 15% non-volatile silicones). These parameter changes allow the composition to maintain both cleaning capability and hydrophobic coating formation capability, resolving the contradiction between cleaning performance and coating formation reliability.
2Object-affected harmful factors
If hydrophobic coating is formed to achieve high contact angles, then water repellence is improved, but compatibility with high water concentration composition deteriorates
Solution Approach 1:
The patent applies parameter changes by controlling the pH within specific ranges and maintaining at least 15% non-volatile silicones content. This allows the composition to remain stable even with high water concentration while still forming hydrophobic coatings with high contact angles, resolving the contradiction between water repellence and composition stability.
3Object-affected harmful factors
If non-volatile aminosilicone concentration is increased to improve hydrophobicity, then contact angle increases, but formulation complexity increases
Solution Approach 1:
The patent simplifies the formulation by specifying a minimum threshold (at least 15% non-volatile silicones) rather than requiring complex combinations of multiple ingredients. This parameter-based approach achieves high hydrophobicity while maintaining formulation simplicity, resolving the contradiction between hydrophobicity and formulation complexity.
