Non-Halogenated Flame Retardant Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire retardant chemical compositions, particularly those halogenated, pose toxicity risks to humans and the environment, necessitating the development of non-halogenated alternatives that are effective and safe.
Innovation Solution
A composition comprising ammonium phosphate, a source of citrate ion, and a source of benzoate ion, with specific ratios and optionally an aqueous solvent, is applied to materials to impart flame retardancy, which is non-toxic and environmentally friendly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If halogenated flame retardant compositions (BFRs and CFRs) are used, then flame retardant effectiveness is improved, but toxicity to humans and environment worsens
Solution Approach 1:
The patent changes the chemical composition parameters by using non-halogenated compounds (ammonium phosphate, citric acid, sodium benzoate) instead of halogenated flame retardants. This parameter change maintains flame retardant effectiveness while eliminating toxicity, directly resolving the contradiction between effectiveness and harmful effects
Solution Approach 2:
The patent creates a composite flame retardant composition combining ammonium phosphate, citric acid, and sodium benzoate in specific ratios. This composite material achieves synergistic effects that provide effective flame retardancy without the toxic properties of individual halogenated compounds, resolving the contradiction between effectiveness and safety
2Object-affected harmful factors
If non-halogenated flame retardant compositions are used, then toxicity to humans and environment is reduced, but flame retardant effectiveness may worsen
Solution Approach 1:
The patent merges multiple non-halogenated compounds (ammonium phosphate as flame retardant, citric acid as acid source, sodium benzoate as preservative) into a single composition. This combination creates synergistic effects that achieve effective flame retardancy while maintaining non-toxicity, resolving the contradiction between safety and effectiveness
Solution Approach 2:
The patent optimizes concentration parameters of each component (ammonium phosphate: 12.7-20 parts, citric acid: 1 part, sodium benzoate: 0.8-2.2 parts) to achieve both effective flame retardancy and non-toxicity, directly addressing the contradiction between effectiveness and safety
