Acetylated MDF Floor Panel with Radiation-Cured Acrylate Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor floor panels, such as laminate and direct print panels, lack the necessary weather resistance and durability for outdoor use, as they are not suitable for exposure to moisture and UV radiation, leading to fading and unsightly decor.
Innovation Solution
A floor panel design featuring a carrier board made of acetylated MDF or HDF, fiber cement, or PVC, with a radiation-cured acrylate film as the decorative or protective layer, and a primer layer for enhanced adhesion and durability, using polymerizable printing inks for improved adhesion and UV resistance, and a water-impermeable layer on the back to prevent water penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If laminate panels with MDF or HDF carrier board are used for interior use, then they are inexpensive and easy to lay, but they are not moisture-resistant and will swell when used outdoors
Solution Approach 1:
The patent applies a radiation-cured acrylate film coating to the carrier board, fundamentally changing the surface properties to achieve moisture resistance while preserving the ease of installation of laminate panels. The curing process transforms the material parameters to enable outdoor use.
Solution Approach 2:
The invention creates a composite structure combining the carrier board (MDF/HDF) with a radiation-cured acrylate film layer. This composite material system integrates the manufacturing advantages of laminate panels with the weather resistance properties of cured polymer coatings.
2Adaptability or versatility
If decor papers are used on laminate panels, then decorative flexibility is achieved, but the printing colors fade over time due to insufficient UV resistance
Solution Approach 1:
The patent uses polymerizable printing inks containing acrylate that can be radiation-cured, changing the chemical properties of the decorative layer to achieve UV resistance. This allows the decor to maintain its flexibility while gaining durability against fading.
Solution Approach 2:
The invention creates a composite decorative system where polymerizable inks are integrated with the acrylate film coating. This combination provides both decorative flexibility and long-term UV resistance, solving the fading problem while maintaining design versatility.
3Strength
If acrylate or melamine resin surfaces are applied to laminate panels, then protective properties are improved, but they do not meet high demands of outdoor weathering without special modifications
Solution Approach 1:
The patent transforms ordinary acrylate or melamine resin surfaces into weather-resistant coatings by applying radiation curing. This parameter change (from uncured to cured state) fundamentally improves outdoor weathering resistance while maintaining protective properties.
Solution Approach 2:
The invention replaces traditional thermal curing or natural drying processes with radiation curing (UV or electron beam). This substitution enables rapid curing and achieves superior weather resistance without requiring special modifications to the resin system.
4Reliability
If tropical woods are used for outdoor floorboards, then good weather-resistant properties are achieved, but they are relatively expensive and environmentally unfriendly
Solution Approach 1:
The patent creates artificial wood floor panels that copy the weather-resistant properties of tropical woods through radiation-cured acrylate film coatings. This copying approach achieves similar durability without the high cost and environmental concerns associated with tropical timber harvesting.
Solution Approach 2:
The invention uses inexpensive carrier boards (MDF/HDF) that would normally have limited outdoor lifespan, but extends their service life through the radiation-cured protective film. This makes economical materials viable for outdoor use, replacing expensive tropical woods.

AI summary
The present invention relates to outdoor floor panels, the front of which is provided with a decorative or protective layer and which have tongue-and-groove coupling elements on their sides. The material of the carrier board is MDF or HDF board made of acetylated wood, a fiber cement board, or is based on polyvinyl chloride, and the decorative or protective layer consists of a radiation-cured acrylate-containing film or a polymer layer with a hardness gradient, wherein the hardness of the polymer layer decreases essentially continuously with increasing depth from the surface of the polymer layer.
