Abstract

The invention provides an environment-friendly flame-retardant glass fiber reinforced PP/PA610 (polypropylene/polyamide 610) alloy material with a high CTI (comparative tracking index) value and a high GWIT (glow-wire ignition temperature) value, which is prepared by following materials by weight percent: 23-41% of PP, 22-41% of PA610, 6-20% of compound type flame retardant, 3-15% of antimony trioxide, 20-30% of glass fiber, 2-10% of compatilizer, 0.1-1% of antioxidant and 0.1-1% of oxidizing materials, wherein the compound type flame retardant is prepared by the following substances by weight percent: 50% of BPS (Brominated Polystyrene), 25% of magnesium hypophosphite and 25% of talcum powders. The invention also provides a preparation method the material. The environment-friendly flame-retardant glass fiber reinforced PP/PA610 alloy material has the advantages that a novel flame-retardant compound system is adopted, so that the GWIT of the material is improved by 50-100 DEG C, the material can pass 850 DEG C glow-wire, the GWIT values of the material is obviously improved due to the addition of glass fibers, meanwhile, the impact performance and the anti-aging performance of the material are improved, the processing mobility and the smoothness are improved, and the friction coefficient is reduced.

Description

technical field [0001] The invention relates to a PP / PA610 alloy material and a preparation method thereof, in particular to an environmentally friendly flame-retardant glass fiber reinforced PP / PA610 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 ...
