Abstract

The invention provides a high-CTI (Creepage Tracking Index) high-GWIT (Glow-Wire Ignition Temperature) environmental-friendly flame-retardant glass fiber reinforced PP / PA612 (Polypropylene / Polyamide 612) alloy material which is prepared from the following raw materials in percentage by weight: 23%-41% of PP, 22%-41% of PA612, 6%-20% of compound flame retardant, 3%-15% of antimony trioxide, 20%-30% of glass fibers, 2%-10% of compatilizer, 0.1%-1% of antioxidant and 0.1%-1% of oxide, wherein the compound flame retardant contains the following materials in percentage by weight: 50% of BPS (Brominated Polystyrene), 25% of magnesium hypophosphite and 25% of talcum powder. The invention also provides a preparation method of the high-CTI high-GWIT environmental-friendly flame-retardant glass fiber reinforced PP / PA612 alloy material. The high-CTI high-GWIT environmental-friendly flame-retardant glass fiber reinforced PP / PA612 alloy material provided by the invention has the advantages that the GWIT value is increased by 50-100 DEG C due to adoption of a novel flame-retardant compounding system, so that the material can pass 850 DEG C glow-wire test; the GWIT value is also obviously increased through the addition of the glass fibers; moreover, and impact property and ageing-resistant property are improved, processing fluidity and smoothness are increased and friction factor is lowered.

Description

technical field [0001] The invention relates to a PP / PA612 alloy material and a preparation method thereof, in particular to an environmentally friendly flame-retardant glass fiber reinforced PP / PA612 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, referred to as PA, is the general term for thermoplastic resins containing repeated amide groups—[NHCO]—on the main chain of the molecule, and its naming is determined by the specific number of carbon atoms in the synthetic monomer , such as PA-6, PA-66, PA-1010, PA-610. PA has high crystallinity and obvious melting point; high surface hardness, wear resistance, small friction coefficient, self-lubrication and noise reduction; good low temperature performance and certain heat resistance (can be used below 100°C); non-toxic , Odorless, no mildew, self-extinguishing, good weather resistance, but ...
