Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panels for outdoor applications, such as laminate and PVC-based panels, are not suitable for harsh weather conditions and moisture, lacking durability and stability.
Innovation Solution
A coated panel manufacturing method using a carrier plate of mineral wool or glass wool, treated with a primer and multiple oligomer layers to enhance adhesion, UV protection, and mechanical properties, including the application of isocyanate-based primers and radiation-curable oligomers to create a durable and scratch-resistant surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laminate panels or PVC-based panels are used for outdoor applications, then they provide inexpensive and easy-to-handle characteristics, but they lack durability and stability when subjected to weather conditions and moisture
Solution Approach 1:
The patent uses a composite structure consisting of an MDF or HDF carrier plate combined with a PVC layer that has been treated with acetylated wood flour or other cellulose-containing materials. This composite approach creates a material that maintains the workability of conventional panels while gaining resistance to moisture and weather conditions through the treated cellulose component.
Solution Approach 2:
The patent modifies the chemical parameters of the PVC material by incorporating acetylated wood flour or cellulose-containing materials, which changes the hygroscopic properties of the panel. This parameter change reduces the panel's affinity for moisture, thereby improving its durability in outdoor conditions while maintaining its base characteristics.
2Stability of the object's composition
If fiber cement panels are used to improve outdoor stability, then they provide good stability, but they exhibit high alkalinity which is a disadvantage
Solution Approach 1:
The patent replaces the fiber cement material with a more favorable composition using MDF or HDF carrier plates treated with acetylated wood flour or cellulose-containing materials. This substitution eliminates the high alkalinity problem while maintaining outdoor stability, effectively discarding the problematic material in favor of a better alternative.
Solution Approach 2:
The patent changes the chemical composition parameters by using acetylated wood flour or cellulose-containing materials instead of fiber cement. This parameter change maintains the dimensional stability needed for outdoor applications while eliminating the harmful high alkalinity characteristic of fiber cement panels.

AI summary
The present invention relates to a method for the manufacturing of a coated panel, in particular a wall, ceiling or flooring panel for applications in outdoor areas, as well as such a panel. The method comprises the following steps: providing a carrier plate of mineral wool and/or glass wool, comprising a front side and a rear side, applying a primer onto the front side of the carrier plate, thereafter applying a liquid first oligomer in an amount of 30 to 150 g/m2 onto the front side of the carrier plate; thereafter applying a liquid second oligomer, which differs from the first oligomer, in an amount of 30 to 180 g/m2 onto the wet surface of the before applied layer of the first oligomer.
