Description
Technical field
The present invention relates to a kind of fire-proof high-temperature resistant nylon composite materials.
Background technology
Polyamide is commonly called as nylon (Nylon), English name Polyamide (PA), although polyamide is because with good machine
Tool performance, chemical-resistant resistance, oil resistant and good electrical insulating property and become the first choice of electronic and electrical industry and auto industry
Material, but because these present fields require all very high to the fire resistance of material, and the polyamides of polyamide and its fiberglass reinforced
The anti-flammability of amine product is all very poor, and its oxygen index (OI) only has 22%, even if the polyamide 6 thickness without fiberglass reinforced reaches 3.2mm,
Molten drop seriously can only achieve UL-94V-2 grades during vertical combustion, and the polyamide 6 after fiberglass reinforced is due to wick effect, its thickness
Even if degree reaches 3.2mm, UL-94 test grades are stepless, thus significantly limit the broader applications of polyamide product.
Therefore, when polyamide is used for Related product, it need to carry out flame-retardant modified.Need a kind of fire-proof high-temperature resistant nylon product.
