Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coating systems for large objects require multiple layers, consuming significant materials, time, and energy due to high-temperature curing processes, and suffer from high moisture absorption and the need for manual application of putty layers.
Innovation Solution
A coating system comprising a putty layer with a polyaspartic acid ester binder and a hardener component of polyisocyanate, and a clear coat layer based on RMA or polyaspartic acid ester binders, which can be applied in thick layers at room temperature, reducing material and energy consumption and eliminating the need for additional primer layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coating systems with four to five layers are used, then adequate protection and surface quality are achieved, but material consumption and production time increase significantly
Solution Approach 1:
The invention combines multiple conventional coating layers into a single-layer system that integrates the protective and decorative functions of primer, putty, filler, and top coat into one multifunctional coating layer, thereby reducing material consumption while maintaining adequate protection quality
Solution Approach 2:
The single-layer coating system performs multiple functions simultaneously: it provides corrosion protection like a primer, fills surface irregularities like putty, smooths the surface like filler, and provides the final decorative finish like top coat, eliminating the need for separate layers
2Reliability
If multiple separate coating layers are applied, then specific functions (adhesion, filling, protection) are achieved, but production time and energy consumption increase
Solution Approach 1:
The invention merges the application of multiple separate coating layers into a single application step, reducing production time while maintaining all necessary coating functions through the multifunctional single-layer system
Solution Approach 2:
The coating system is pre-formulated to contain all necessary functional components (adhesion promoters, fillers, protective agents) in a single composition, eliminating the need for sequential application of multiple layers and reducing production time
3Reliability
If high-temperature curing processes are used for conventional coating layers, then adequate curing and cross-linking are achieved, but energy consumption increases significantly
Solution Approach 1:
The invention changes the curing parameters from high-temperature conventional curing to room-temperature or low-temperature curing by using a two-component polyisocyanate system that cures through moisture reaction, significantly reducing energy consumption while maintaining adequate curing quality
Solution Approach 2:
The coating system utilizes a chemical phase transition from liquid components to cured coating through moisture-induced cross-linking of polyisocyanates, eliminating the need for thermal energy input and enabling ambient temperature curing
4Manufacturing precision
If putty layers are applied manually with spatula, then surface irregularities can be compensated, but labor intensity and application time increase
Solution Approach 1:
The invention combines the putty function with the decorative top coat into a single sprayable coating layer that simultaneously fills surface irregularities and provides the final finish, eliminating manual spatula application and enabling efficient spray application
