Description

A kind of high-glowing-filament-temperature flame-retardancy reinforced plastic PA66 and preparation method thereof
Technical field
The present invention relates to a kind of plastics, more particularly to a kind of high-glowing-filament-temperature flame-retardancy reinforced plastic PA66 and preparation method thereof.
Background technique
Since PA66 has excellent mechanical strength, wearability, self-lubrication, corrosion resistance and preferable processing and forming Property, but the impact resistant strength under heat resistance and cryogenic conditions is insufficient, the defect in terms of dimensional stability and electrical property, makes pushing away for it It is wide to use by certain limitation.Since in recent years, with the progress of PA66 modification technology, as electric appliance component proprietary material In new material, do not require nothing more than its rigidity high, heat resistance and good stability of the dimension and need good processability and fire-retardant Property, so flame-proof enhancement PA 66 has very big market prospects.
