Abstract

The invention discloses a high-impact-resistance less-fiber-floating long glass fiber reinforced polypropylene material which is prepared from the following components in parts by weight: 10-80% of long glass fiber reinforced polypropylene master batch and 20-90% of high-impact-resistance less-fiber-floating master batch. The long glass fiber reinforced polypropylene master batch is prepared from 8-80% of polypropylene copolymer, 0-80% of polypropylene homopolymer, 10-60% of glass fiber, 1-10% of grafted polypropylene, 0.1-2% of antioxidant and 0.2-2% of processing aid. The high-impact-resistance less-fiber-floating master batch is prepared from 20-80% of polypropylene copolymer, 0-50% of glass fiber, 0-30% of elastomer, 0-30% of grafted elastomer, 0-10% of low-viscosity polyamide resin, 0.1-2% of antioxidant and 0.2-5% of processing aid. The polypropylene material disclosed by the invention has the advantages of high glossiness and less fiber floatings; and the finished product made of the polypropylene material has the advantages of good drop resistance and processability, and can be used for replacing the parts made of engineering plastics.

Description

technical field [0001] The invention relates to a polypropylene material, in particular to a polypropylene material reinforced with high impact resistance and low floating fiber long glass fiber. Background technique [0002] Polypropylene resin (PP) is a general-purpose plastic with a wide range of uses. It is obtained by polymerization of propylene monomer. The advantages of polypropylene resin are low density, low price, excellent chemical corrosion resistance, good mechanical properties, Outstanding folding resistance and good formability. As a typical crystalline material, its melting point is around 165°C. [0003] Long glass fiber reinforced PP material has high strength, high impact resistance, and good dimensional stability. It is a "strong and tough" material. After PP is reinforced with glass fiber, its mechanical properties, heat resistance and size are greatly improved. stability. In practical applications, plastic can replace steel and reinforced engineering...
