(OH) 3, Mg (OH) 2 is fire-retardant main body, and Firebrake ZB is smoke suppressant.Environment friendly non-halogen element is characterized in, it is cheap.It is another kind of, adopt
It is fire-retardant main body with organic fire-retardant, including halogen flame, phosphorus flame retardant and nitrogenated flame retardant etc..Wherein halogen flame
For the most fire retardant of present consumption, particularly bromide fire retardant, it is extensively selected by producer.
But need to add substantial amounts of inorganic constituentss using inorganic combustion inhibitor, so the physical property of sizing material can be particularly
Tensile property is impacted；
It is little using halogen flame addition, and good flame retardation effect, but smoke toxicity is larger, and can produce during burning halogen-containing has
Poisonous gas；
Then there is addition greatly using the EPDM flame retardant glue material containing phosphorus flame retardant and nitrogenated flame retardant, and it is expensive,
