Elastomeric Resin Treated Paper for Laminated Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of rigid melamine-treated papers in laminated panels is hindered by a short shelf life, sensitivity to heat and moisture, brittleness, and increased costs due to the need for multiple layers and stress compensation, leading to manufacturing challenges and defects.
Innovation Solution
A laminated panel structure featuring a core panel with a single finishing printed paper layer treated with an elastomeric resin, which functions as both a decorative and wear layer, reducing the need for separate layers and minimizing stress on the core panel, thereby enhancing durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid melamine-treated paper layers are used for decorative and wear layers, then durability and wear resistance are improved, but brittleness and susceptibility to cracking increase
Solution Approach 1:
The patent uses a composite structure consisting of a flexible backing layer combined with a melamine-treated paper layer containing abrasion-resistant particles. This composite approach allows the melamine layer to provide wear resistance while the flexible backing layer compensates for brittleness and prevents cracking, resolving the contradiction between durability and reliability.
2Reliability
If multiple treated paper layers are used (decorative layer, wear layer, balancing layer), then functional performance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the decorative layer and wear layer into a single integrated melamine-treated paper layer with printed design and embedded abrasion-resistant particles. The flexible backing layer provides both structural support and stress compensation functions. This merging reduces the traditional multi-layer structure to a simpler two-layer construction while maintaining all necessary functions.
Solution Approach 2:
The single melamine-treated paper layer serves multiple functions simultaneously: it provides the decorative appearance through printing, delivers wear resistance through embedded particles, and creates structural balance when combined with the flexible backing layer. This multi-functionality eliminates the need for separate decorative, wear, and balancing layers.
3Strength
If melamine-treated paper layers are used, then wear resistance is improved, but shelf life decreases due to sensitivity to heat and moisture
Solution Approach 1:
The patent employs a flexible backing layer that is inherently more resistant to moisture and heat degradation compared to traditional rigid melamine layers. This flexible substrate provides a more stable platform that maintains its properties over time and under varying environmental conditions, thereby extending the shelf life of the laminate panel while still supporting the wear-resistant melamine surface layer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces production costs, extends shelf life, and eliminates the need for a balancing layer, resulting in a more stable and cost-effective laminated panel with improved handling and appearance.
Implementation Method 1
a single finishing printed paper layer which finishing printed paper layer has been treated with, or impregnated with, an elastomeric resin
Implementation Method 2
the action of heat and pressure on the amino resin treated papers acts to liquefy and cure the amino resin, and thereby bond the various individual layers to each other

AI summary
A laminated panel is provided which comprises, or consists of, a core panel to which an elastomeric resin impregnated single finishing printed paper layer has been applied. The paper for the single finishing printed paper layer is printed to provide a design feature on the laminated panel. Preferably, the design feature has been printed on a lower surface of the single finishing printed paper layer. As a result of the resin impregnation and heating and pressing operations, the single finishing printed paper layer becomes translucent or transparent, and thus allows the printed design feature to become visible. The design feature can be printed onto the single finishing printed paper prior to treatment with the elastomeric resin, or printed onto the previously treated elastomeric resin impregnated paper. The laminated panels can be used in the production of laminated flooring, wall panels or furniture panels.
