定义
A specialized chemical additive incorporated into electrical-grade epoxy resin compounds to suppress ignition, slow flame propagation, and reduce smoke generation during fire events. It functions by interrupting the combustion cycle through chemical or physical mechanisms when exposed to heat or flame, enhancing the fire safety of electrical components and systems.
工作原理
Works through mechanisms such as endothermic decomposition (absorbing heat), formation of protective char layers, release of flame-quenching gases (like water vapor or inert gases), or radical scavenging in the gas phase to disrupt the combustion chain reaction. In epoxy resins, it typically integrates into the polymer matrix to provide persistent protection.
材料
Common materials include halogenated compounds (e.g.brominated or chlorinated organics)phosphorus-based compounds (e.g.phosphatesphosphonates)inorganic fillers (e.g.aluminum trihydratemagnesium hydroxide)nitrogen-based compounds (e.g.melamine derivatives)or synergistic blends. Selection depends on required flame retardancy levelelectrical propertiesand environmental regulations.

常见问题

What is the difference between halogenated and halogen-free flame retardants?

Halogenated flame retardants (e.g., brominated types) are highly effective but may release toxic gases when burned. Halogen-free alternatives (e.g., phosphorus or inorganic types) are environmentally preferred, though they may require higher loading levels to achieve similar flame retardancy.

How does a flame retardant affect the electrical properties of epoxy resin?

It can influence dielectric strength, insulation resistance, and thermal conductivity. Proper formulation ensures minimal impact, but excessive loading may reduce electrical performance, requiring balance between fire safety and functional requirements.
