Caprolactone-Modified Acryl Resin Coating for Shatter-Proof Tempered Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shatter-proof tempered glass used in vehicles, especially in panorama roofs, is prone to breaking due to the presence of a ceramic layer, which compromises safety and strength, leading to dangerous situations when impacted.
Innovation Solution
A coating composition comprising caprolactone-modified acryl resin, acryl polyol, and a small amount of polyurethane resin is applied to tempered glass, enhancing its shatter-proof function by removing the need for a ceramic layer and improving durability and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ceramic layer is applied to tempered glass to provide shatter-proof function, then safety is improved, but the glass becomes prone to breaking under impact
Solution Approach 1:
The patent removes the ceramic layer from the glass structure entirely, extracting the harmful component that caused the contradiction between shatter-proof function and impact resistance. The shatter-proof capability is then achieved through a different mechanism using a coating composition applied to the glass surface.
Solution Approach 2:
The patent changes the material parameters by replacing ceramic coating with a polymer-based coating composition containing caprolactone-modified acryl resin, acryl polyol, and polyurethane resin. This parameter change transforms the coating material from rigid ceramic to flexible polymer, resolving the strength-shatterproof contradiction.
2Reliability
If a ceramic layer is applied to tempered glass, then shatter-proof function is provided, but image clarity deteriorates
Solution Approach 1:
The patent extracts the ceramic layer that blocked light and degraded image clarity, replacing it with a transparent or translucent polymer coating that maintains optical performance while providing shatter-proof functionality.
Solution Approach 2:
The patent uses a composite coating composition combining caprolactone-modified acryl resin, acryl polyol, and polyurethane resin to achieve both optical transparency and shatter-proof properties, resolving the contradiction between image clarity and safety function.
3Reliability
If a ceramic layer is applied to tempered glass, then shatter-proof function is achieved, but durability in terms of heat-resistance, water resistance, and weather resistance deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters of the coating material from ceramic to polymer-based substances with improved resistance properties. The caprolactone-modified acryl resin and polyurethane resin provide superior heat-resistance, water resistance, and weather resistance compared to ceramic coatings.
Solution Approach 2:
The patent employs a composite polymer coating system where caprolactone-modified acryl resin provides base protection, acryl polyol enhances flexibility and adhesion, and polyurethane resin adds durability and resistance properties, collectively improving long-term performance.
