Abstract
The invention provides a high-CTI (Creepage Tracking Index) high-GWIT (Glow-Wire Ignition Temperature) environmental-friendly flame-retardant glass fiber reinforced PP (Polypropylene) material which is prepared from the following raw materials in percentage by weight: 45%-68.8% of PP, 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 material. The high-CTI high-GWIT environmental-friendly flame-retardant glass fiber reinforced PP material provided by the invention has the advantages that the GWIT value is increased by 50-100 DEG C by 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; in addition, impact property and ageing-resistant property are improved, processing fluidity and smoothness are enhanced, and friction factor is lowered.
Description
technical field [0001] The invention relates to a PP material and a preparation method thereof, in particular to an environmentally friendly flame-retardant glass fiber reinforced PP material with a high CTI value and a high GWIT value and a preparation method thereof. Background technique [0002] Polypropylene, English name polypropylene, referred to as PP, molecular formula: (C 3 h 6 )n is a thermoplastic resin obtained by polymerizing propylene. According to the position of the methyl group, it can be divided into three types: isotaetic polypropylene, atactic polypropylene and syndiotactic polypropylene. PP is non-toxic, tasteless, low density, strength, stiffness, hardness, and heat resistance are superior to low-pressure polyethylene, and can be used at around 100 °C; it has good electrical properties and high-frequency insulation, which is not affected by humidity, and is suitable for production General mechanical parts, corrosion-resistant parts and insulating par...
