AI Technical Summary
Existing halogen-free cable sheath materials have poor smoke suppression effects during combustion, and the smoke density and total smoke release are difficult to meet high standard requirements. Traditional halogen-free flame-retardant polyolefin systems have high heat release and smoke generation during combustion, and low flame retardant efficiency.
Using calcium alginate as the core and coated with magnesium hydroxide and aluminum hydroxide, a gradient decomposition flame retardant structure is designed. A dense carbon layer is formed by catalytic carbonization at high temperature to suppress smoke generation.
It significantly reduces the maximum smoke density and total smoke release during material combustion, forming a highly efficient and stable char layer physical barrier, thus improving the synergistic effect of flame retardancy and smoke suppression.
