Fire Retardant Composition with Monoethanolamine for Wood Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Natural fiber products, such as wood and wood-based panels, face challenges in achieving uniform fire retardancy due to difficulties in homogeneous distribution of fire retardant compositions, often resulting in weak spots and visible crystallization, which can compromise quality standards and require excessive application.
Innovation Solution
A fire retardant composition combining fire retardants with monoethanolamine, optimizing their weight ratio between 1:5 and 1:50, which acts as a crystallization inhibitor, wetting agent, and solubility enhancer, allowing for reduced viscosity and homogeneous application without crystallization, thereby improving fire retardancy and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large amounts of fire retarding composition are applied to natural fiber products, then fire retarding properties are improved, but the amount of substance applied increases and crystallization effects worsen
Solution Approach 1:
The patent changes the chemical parameters of the fire retarding composition by incorporating specific solubilizers and synergists that enhance the effectiveness of boric acid. This allows achieving the required fire retarding properties with lower amounts of composition applied, thus reducing crystallization effects while maintaining reliability
Solution Approach 2:
The patent creates a composite fire retarding composition that combines boric acid with solubilizers (such as organic acids or their salts) and synergists (such as phosphorus compounds). This composite approach enhances the fire retarding efficiency per unit of substance applied, reducing the total quantity needed while improving effectiveness
2Reliability
If fire retarding composition is applied to natural fiber products, then fire retarding properties are improved, but visible crystallization layer is formed on the surface
Solution Approach 1:
The patent modifies the chemical composition parameters by adding solubilizers that prevent crystallization of boric acid on the surface. This allows the fire retarding composition to remain soluble and evenly distributed, preventing visible crystallization layers while maintaining fire retarding effectiveness
Solution Approach 2:
The patent introduces solubilizers as intermediary substances that mediate between the fire retarding agents (boric acid) and the natural fiber product surface. These solubilizers prevent direct crystallization of boric acid on the surface, maintaining aesthetic appearance while ensuring fire retarding properties
3Reliability
If fire retarding composition is applied to natural fiber products, then fire retarding properties are improved, but homogeneous distribution is difficult to achieve
Solution Approach 1:
The patent introduces solubilizers and surfactants as intermediary substances that facilitate uniform distribution of the fire retarding composition throughout the natural fiber product. These intermediaries improve wetting and penetration properties, ensuring homogeneous distribution without weak spots
Solution Approach 2:
The patent changes the physical parameters of the composition by adjusting solubility and viscosity through the addition of solubilizers. This enables the composition to penetrate and distribute uniformly throughout the natural fiber product, achieving homogeneous fire retarding properties
