One-Component Organic Render Composition with Rain Fastness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing organic render compositions face challenges in combining long processing time with early rain fastness, often requiring multi-component systems that are costly, prone to user errors, and contain hazardous amine components with strong odors, while also having limited temperature and humidity ranges, necessitating separate summer and winter recipes.
Innovation Solution
A one-component organic render composition comprising acrylic ester-styrene-copolymer, earth alkali carbonates with specific particle sizes, cellulose ether, phyllosilicate, and non-ionogenic fatty acid derivative, which provides a long processing time, early rain fastness, and broad temperature and humidity usability without amine components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If amine components are added to improve quick rain fastness, then rain fastness is improved, but processing time is reduced and health risks increase
Solution Approach 1:
The patent removes harmful amine components from the composition while extracting and retaining only the beneficial quick rain fastness property through alternative safe ingredients, thereby eliminating health risks and odor issues while maintaining performance
Solution Approach 2:
The patent changes the chemical parameters by substituting amine components with alternative compounds that provide similar rain fastness functionality without the negative side effects, and adjusts processing parameters to maintain extended working time
2Reliability
If multi-component systems are used to achieve desired properties, then performance is improved, but device complexity and user error risk increase
Solution Approach 1:
The patent combines multiple previously separate functional components into a single integrated one-component system, merging the binder, aggregates, and functional additives into a pre-mixed composition that maintains all desired properties without requiring on-site mixing
Solution Approach 2:
The patent creates a universal one-component composition that performs multiple functions (binding, texturing, rain fastness, temperature adaptability) simultaneously, eliminating the need for separate multi-component systems
3Adaptability or versatility
If separate summer and winter recipes are used to cover different temperature ranges, then temperature adaptability is improved, but device complexity and costs increase
Solution Approach 1:
The patent develops a universal composition formulation that functions effectively across the entire temperature range from -30°C to +30°C, eliminating the need for separate summer and winter recipes and simplifying inventory and application
