Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flame retardant coatings for wood surfaces are either non-transparent, contain toxic substances, or lack the necessary durability and adhesion, making them unsuitable for effective and aesthetically pleasing wood coating applications.
Innovation Solution
Development of stable, transparent aqueous dispersions of micronized brominated epoxy polymers combined with a binding agent, which are applied to wood surfaces to form a homogeneous, flexible, and non-leaching flame retardant coating, utilizing milling techniques to achieve suitable particle sizes and incorporating additives for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional flame retardant coatings are applied to wood surfaces, then flammability is reduced, but transparency and aesthetic appearance are lost
Solution Approach 1:
The patent changes the physical-chemical parameters of the flame retardant formulation by using micronized particles (1-10 micrometers) suspended in aqueous dispersion with specific surfactant concentrations and pH levels, enabling the coating to remain transparent while maintaining flame retardant efficacy
Solution Approach 2:
The patent creates a composite coating system combining micronized brominated epoxy polymer particles, waterborne adhesive emulsion, and surfactants, where each component contributes specific properties: the micronized particles provide flame retardancy, the adhesive provides binding, and the surfactant ensures dispersion and transparency
2Object-affected harmful factors
If flame retardant coatings are applied to wood surfaces, then flammability is reduced, but adhesion and durability are insufficient
Solution Approach 1:
The patent introduces waterborne adhesive emulsion as an intermediary substance between the micronized flame retardant particles and the wood surface, which enhances adhesion by providing binding functionality while maintaining the transparency and flame retardant properties of the coating
Solution Approach 2:
The patent ensures continuous protective action by formulating a coating that provides both immediate adhesion through the waterborne adhesive and sustained flame retardant protection through the micronized particles, creating a durable and reliable coating system
3Object-affected harmful factors
If flame retardant coatings are applied to wood surfaces, then flammability is reduced, but the coating becomes non-aqueous and less environmentally friendly
Solution Approach 1:
The patent replaces conventional organic solvent-based flame retardant systems with an aqueous dispersion system, substituting water as the continuous phase to eliminate toxic volatile organic compounds while maintaining the flame retardant functionality through properly formulated micronized particles and surfactants
