Binder Composition for Flexible Composite Laminates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforced wooden laminates suffer from limited mechanical strength and brittleness, leading to handling difficulties and dust formation during manufacturing and lamination processes, necessitating the development of more flexible and less brittle nonwoven materials for composite materials used in construction and furniture.
Innovation Solution
A new binder composition comprising a B-stage binder and a thermoplastic emulsion, preferably polyolefin or polyurethane-based, is applied to textile structures, enhancing their flexibility and impact resistance, and reducing brittleness and dust issues during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional B-stage binder is used for reinforcing nonwoven, then mechanical strength is achieved, but brittleness increases causing handling problems and dust formation
Solution Approach 1:
The patent combines B-stage binder with thermoplastic emulsion to create a composite binder system. The B-stage binder provides mechanical strength while the thermoplastic emulsion component reduces brittleness and improves flexibility, allowing the nonwoven to be handled more easily during manufacturing and lamination processes without generating dust
Solution Approach 2:
The patent modifies the binder composition by adding thermoplastic emulsion components and adjusting chemical parameters such as formaldehyde-free formulations and specific resin ratios. These parameter changes transform the binder from a brittle state to a more flexible state that maintains strength while reducing dust formation and handling difficulties
2Strength
If traditional B-stage binder is used for reinforcing nonwoven, then mechanical strength is achieved, but dust formation occurs during manufacturing and lamination
Solution Approach 1:
The composite binder system combines B-stage binder with thermoplastic emulsion, where the thermoplastic component acts as a binder that holds the nonwoven fibers together more effectively. This reduces fiber detachment and dust formation during manufacturing and lamination processes while maintaining the required mechanical strength of the reinforcing nonwoven
Solution Approach 2:
The patent employs formaldehyde-free formulations and adjusts chemical composition parameters to reduce dust formation. The modified binder chemistry creates a more stable nonwoven structure that resists generating dust particles during handling and processing
3Ease of operation
If flexiblity is improved by adding thermoplastic emulsion, then handling capability increases, but processing complexity increases
Solution Approach 1:
The patent optimizes the thermoplastic emulsion content and formulation parameters to achieve the desired flexibility balance. By carefully controlling the emulsion concentration and type, the nonwoven gains sufficient flexibility for handling while avoiding excessive softness that would complicate subsequent lamination processing
