Abstract

The invention provides an environment-friendly and flame-retardant glass fibre reinforced PP / PA1010 alloy material with a high CTI (comparative tracking index) valve and a high GWIT (glow wire ignition temperature) value, which is prepared from raw materials in percentage by weight: 23-41% of PP (propene polymer), 22-41% of PA1010, 6-20% of a compound flame retardant, 3-15% of antimonous oxide, 20-30% of glass fibres, 2-10% of a compatilizer, 0.1-1% of an antioxidant and 0.1-1% of oxides, wherein the compound flame retardant is composed of substances in the percentage by weight: 50% of BPS (brominated polystyrene), 25% of magnesium hypophosphite and 25% of talcum powder. The invention further provides a preparation method for the material aforementioned. The material and the preparation method provided by the invention have the following advantages that with the adoption of a novel flame-retardant compound system, the GWIT value of the material is increased by 50-100 DEG C, and glow wires at 850 DEG C can pass; due to the addition of the glass fibres, the GWIT value of the material is also obviously increased; simultaneously, the impact performance and the ageing resistance of the material are improved, the processing flowability and the smoothness are enhanced, and the friction coefficient is lowered.

Description

technical field [0001] The invention relates to a PP / PA1010 alloy material and a preparation method thereof, in particular to an environmentally friendly flame-retardant glass fiber reinforced PP / PA1010 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, bu...
