Printed Concrete Surface Composition for Flow and Curing Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for printing on concrete elements, particularly uncured wet concrete, fail to achieve desired patterns and adhesion due to inadequate flow control and compatibility with curing conditions, as seen in DE 10 2006 014 900 A1, which does not address the exact printing composition or adhesion to cured concrete.
Innovation Solution
A printing composition comprising a binder A with siloxane and silane is applied to uncured concrete, allowing it to flow in desired directions and adhere well to the concrete, while being compatible with curing processes, using methods like inkjet printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If printing composition is applied to uncured wet concrete to enable flowing patterns, then pattern formation capability is improved, but adhesion to cured concrete deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the binder by incorporating specific siloxane and silane compounds. These chemical parameter changes enable the binder to maintain flowability during application while developing strong adhesion properties after curing, thus resolving the contradiction between pattern formation capability and adhesion reliability.
Solution Approach 2:
The patent uses a composite binder system combining siloxane and silane components. This composite material approach allows the printing composition to exhibit dual characteristics: fluidity for pattern formation before curing and strong adhesion after curing, effectively resolving the technical contradiction.
2Adaptability or versatility
If printing composition flows extensively in horizontal and vertical directions to create patterns, then pattern diversity is improved, but control over final structure deteriorates
Solution Approach 1:
The patent employs a dynamic binder system where the siloxane and silane components provide controlled flow characteristics. The binder maintains fluidity during application to allow pattern diversity while progressively setting during curing to ensure precise control over the final structure, resolving the contradiction between adaptability and manufacturing precision.
3Shape
If printing is performed on uncured concrete to enable flowing patterns, then pattern formation is improved, but compatibility with thermal curing deteriorates
Solution Approach 1:
The patent changes the thermal stability parameters of the printing composition by selecting specific siloxane and silane compounds that are compatible with thermal curing processes. These parameter changes ensure that the pattern-forming composition remains stable during thermal curing, resolving the contradiction between pattern formation and curing compatibility.
