Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicate paints are used to achieve high adhesion and UV resistance, then durability is improved, but flexibility deteriorates causing cracking and peeling on non-dimensionally stable substrates
Solution Approach 1:
The patent combines silicate binders with organic polymer binders to create a hybrid coating system. The silicate component provides adhesion and UV resistance, while the organic polymer component provides flexibility and elasticity. This merging of two different binder systems allows the coating to simultaneously achieve durability and flexibility, preventing the cracking and peeling that occurs with pure silicate paints on non-dimensionally stable substrates.
Solution Approach 2:
The invention uses composite material structure by integrating inorganic silicate particles and organic polymer matrices into a single coating composition. This composite approach allows the coating to exhibit both the rigid, durable properties of silicates and the flexible, elastic properties of organic polymers, resolving the contradiction between durability and flexibility.
2Stability of the object's composition
If organic polymers are added to silicate paints to improve elasticity, then flexibility is improved, but compatibility deteriorates due to limited organic polymer selection in highly alkaline conditions
Solution Approach 1:
The patent modifies the pH parameter of the silicate paint formulation to make it less alkaline, thereby improving the compatibility with organic polymers. By adjusting the pH level, the invention creates a more favorable chemical environment that allows a wider range of organic polymers to be used without decomposition, thus improving both flexibility and compatibility simultaneously.
3Ease of operation
If water-based dispersion coating compositions are used to achieve easy application and elasticity, then ease of operation is improved, but weather resistance deteriorates due to partial destruction of organic polymers under UV radiation
Solution Approach 1:
The invention merges water-based dispersion coating compositions with silicate binders to create a hybrid system. The water-based dispersion component provides ease of application and elasticity, while the silicate binder component provides enhanced weather resistance and UV stability. This combination allows the coating to maintain both easy application properties and improved durability against environmental factors.
