Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire retardant compositions for wood composite panels often interfere with the functionality of resins used in their production, leading to reduced bond strength and increased resin consumption, and intumescent formulations applied in coatings degrade the resin, making production inefficient and costly.
Innovation Solution
A fire retardant composition with a pH regulated to a specific range using pH regulators to ensure compatibility with resins, allowing intumescent formulations to be incorporated within the panels without degrading the resin, thereby enhancing bond strength and reducing resin consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire retardant compositions are added to wood composite panels, then fire resistance is improved, but bond strength of resin is reduced
Solution Approach 1:
The patent applies parameter changes by precisely controlling the pH of the fire retardant composition to specific ranges (pH 4.0-6.0 for UF resins, pH 6.0-8.0 for MUF resins, pH 4.0-6.0 for MDI resins). This pH optimization resolves the contradiction by maintaining resin functionality and bond strength while preserving fire retardant effectiveness, eliminating the need to increase resin consumption.
Solution Approach 2:
The patent creates a composite system by formulating fire retardant compositions with specific pH regulators and additives that are compatible with different resin types. This composite approach allows the fire retardant composition to work synergistically with the resin rather than interfering with it, maintaining both fire resistance and bond strength simultaneously.
2Reliability
If intumescent formulations are applied as coatings on finished panels, then fire resistance is improved, but resin degradation occurs during production
Solution Approach 1:
The patent applies preliminary action by incorporating pH regulators and stabilizing additives into the fire retardant composition before panel production. This pre-formulation ensures that the intumescent formulation remains stable during the manufacturing process and only activates under fire conditions, preventing premature resin degradation while maintaining fire resistance.
Solution Approach 2:
The patent uses pH regulators and additives as intermediaries between the intumescent formulation and the resin. These intermediaries protect the resin from degradation by controlling the chemical environment, allowing the intumescent formulation to be incorporated into the panel without compromising resin stability during production.
3Stability of the object's composition
If higher amounts of resin are used to compensate for reduced bond strength, then cohesion of panels is improved, but production cost increases
Solution Approach 1:
The patent resolves this contradiction by changing the pH parameter of the fire retardant composition to optimize resin performance. By controlling pH within specific ranges, the resin maintains its bonding capability at normal consumption levels, eliminating the need to increase resin用量 to compensate for performance loss, thus reducing production costs while maintaining cohesion.
4Reliability
If pH of fire retardant composition is not controlled, then fire retardant properties are maintained, but compatibility with resin is reduced
Solution Approach 1:
The patent applies parameter changes by optimizing and controlling the pH of the fire retardant composition to specific ranges that are compatible with different resin types. This pH control enables the composition to maintain its fire retardant properties while simultaneously ensuring compatibility and optimal performance with the resin system.
