Melamine-Bonded Panel Structure Without Adhesive Interlayers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel manufacturing methods face issues with delamination and increased thickness and cost due to the use of intermediate adhesive layers between melamine resin and PVC boards, and the need for fiberglass layers in waterproof panels.
Innovation Solution
A panel design featuring a top layer with a melamine-based resin that is hardened directly on the substrate using a binder, such as a urethane-based binder, which improves adhesion and eliminates the need for separate gluing and fiberglass layers, while incorporating water-absorbing substances to facilitate the curing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an intermediate adhesive layer is used between melamine resin and PVC board, then the adhesion between layers is improved, but the panel thickness and manufacturing cost increase
Solution Approach 1:
The patent removes the intermediate adhesive layer from the panel structure, eliminating the source of delamination problems while maintaining layer adhesion through direct bonding between melamine resin and PVC board
Solution Approach 2:
The patent combines the adhesive function directly into the melamine resin layer itself, which now serves both as the decorative/wear-resistant layer and as the bonding agent to the PVC substrate, eliminating the need for a separate adhesive layer
2Strength
If an intermediate adhesive layer is used between melamine resin and PVC board, then the adhesion between layers is improved, but the manufacturing cost increases
Solution Approach 1:
The patent removes the intermediate adhesive layer from the panel structure, eliminating the source of delamination problems while maintaining layer adhesion through direct bonding between melamine resin and PVC board
Solution Approach 2:
The patent combines the adhesive function directly into the melamine resin layer itself, which now serves both as the decorative/wear-resistant layer and as the bonding agent to the PVC substrate, eliminating the need for a separate adhesive layer
3Reliability
If fiberglass layers are added to waterproof panels, then the waterproof performance is improved, but the panel thickness and cost increase
Solution Approach 1:
The patent removes the fiberglass reinforcement layer from the panel structure, eliminating unnecessary complexity while maintaining structural integrity through the inherent properties of the PVC board and melamine resin combination
Solution Approach 2:
The patent changes the material parameters by using high-density PVC board that provides sufficient structural strength and waterproof performance without requiring additional fiberglass reinforcement layers
