Abstract

The invention relates to a flame-retardant glass fiber reinforced PA6 (polyamide 6) / PPO (P-Polyphenylene Oxide) alloy material and a preparation method thereof. The alloy material comprises the following components by weight percent: 23-41% of PA6, 22-41% of PPO, 6-20% of compound type flame retardant, 3-15% of antimonous oxide, 20-30% of glass fiber, 2-10% of compatilizer, 0.1-1% of antioxidant and 0.1-1% of oxidizing material. The raw materials are put into a high mixing machine to be mixed for 2-5min and then are discharged, and then a doubles-screw extruder is used for extruding and pelletizing so as to obtain the flame-retardant glass fiber reinforced PA6 / PPO alloy material. Compared with the prior art, the flame-retardant glass fiber reinforced PA6 / PPO alloy material has the advantages that being high in temperature of a glowing filament, environment-friendly, balanced in comprehensive properties, high in CTI (Comparative Tracking lndex) and GWIT (Glow-Wire Flammability Index), and the like.

Description

technical field [0001] The invention relates to a PA6 / PPO alloy material, in particular to an environmentally friendly flame-retardant glass fiber reinforced PA6 / PPO alloy material with a high CTI value and a high GWIT value and a preparation method thereof. Background technique [0002] Nylon (Nylon), Chinese name polyamide, English name Polyamide, is a general term for thermoplastic resins containing repeated amide groups -[NHCO]- on the main molecular chain. Its name is determined by the specific number of carbon atoms in the synthetic monomer, such as: nylon-6, 66, 1010, 610. It has high crystallinity and obvious melting point; it has high surface hardness, wear resistance, small friction coefficient, and self-lubrication and noise reduction. It has good low temperature performance and certain heat resistance (it can be used below 100 degrees). Non-toxic, odorless, non-mildew, self-extinguishing, good weather resistance, but poor dyeing. PPO is one of the five general...
