Solution Overview
Problem
Current silicone modified polyesters used in coating applications have high viscosities, requiring volatile organic compounds (VOCs) as solvents, and their emulsification process is complex, increasing production time and cost.
Innovation Solution
A silicone modified organic polymer is developed as the reaction product of an organic polyol, a silicone resin, and a hydrophilic silane, which is water dispersible without the need for emulsification, allowing for direct dispersion in water or optional emulsification for coating compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicone modified polyesters are used in coating applications, then good coating performance is achieved, but high viscosity requires VOC solvents and complex emulsification process
Solution Approach 1:
The patent modifies the chemical structure of silicone modified polyesters by incorporating hydrophilic groups (such as polyethylene glycol, polypropylene glycol, or carboxyl groups) into the polymer chain. This parameter change in molecular structure enables direct water dispersibility without complex emulsification processes, while maintaining the desired coating performance properties
Solution Approach 2:
The patent creates a composite material system combining silicone modified polyester with hydrophilic functional groups and water dispersible additives. This composite approach allows the material to be directly dispersed in water to form stable coatings, eliminating the need for separate emulsification steps and reducing process complexity
2Reliability
If silicone modified polyesters are used in coating applications, then good coating performance is achieved, but VOC solvents are required which increases environmental harm
Solution Approach 1:
The patent changes the solubility parameter of the silicone modified polyester by introducing hydrophilic functional groups into the polymer structure. This enables the material to be directly dispersed in water instead of requiring VOC solvents, thereby eliminating harmful VOC emissions while maintaining coating performance
Solution Approach 2:
The patent converts the high viscosity problem (which originally required VOC solvents) into a benefit by using water as the dispersing medium. The hydrophilic modification allows the viscous material to be directly dispersed in water, turning the harmful VOC requirement into an environmentally friendly water-based system
3Ease of operation
If emulsification process is used for silicone modified polyesters, then water dispersibility is achieved, but production time and cost increase
Solution Approach 1:
The patent incorporates hydrophilic groups into the polymer structure during the synthesis stage, performing the water dispersibility preparation in advance. This preliminary chemical modification eliminates the need for separate emulsification steps during production, thereby reducing production time and cost while maintaining water dispersibility
