[0032] A high-strength, high-toughness, high-rigid polypropylene composite material is prepared by the following method:
[0033] (1) Weigh the components in parts by weight according to Table 1: dry glass fiber;
[0034] (2) Add the weighed polypropylene, thermoplastic elastomer, PP-g-MAH, antioxidant, and coupling agent into a high-speed mixer for low-speed mixing;
[0035] (3) Add the mixed materials into the extruder, and feed the glass fiber into the extruder through the feeding hole in the middle of the extruder, melt and blend, cool and cut into pellets after extrusion, and obtain the polypropylene composite material.

Abstract
The invention belongs to the field of high polymer materials, and relates to a polypropylene composite material and a preparation method thereof. The polypropylene composite material disclosed by the invention is prepared from the following components in parts by weight: 1500-2000 parts of polypropylene, 800-1000 parts of glass fibre, 60-80 parts of thermoplastic elastomer, 20-30 parts of PP-g-MAH, 8-12 parts of antioxygen, and 1-3 parts of coupling agent. According to the invention, the flowing property of the polypropylene composite material is increased; the interface bonding strength between glass fibre and polypropylene is increased; and the prepared polypropylene composite material has the characteristics of being high in strength, toughness and rigidity.
Description
technical field [0001] The invention belongs to the field of polymer materials, and relates to a polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is a general-purpose thermoplastic with excellent acid and alkali corrosion resistance, and has excellent mechanical and processing properties. However, in some engineering applications, its performance cannot meet the requirements. Glass fiber is used to reinforce polypropylene. The material has excellent mechanical properties, heat resistance and dimensional stability, and can be widely used in automobiles, electrical appliances, machinery, Military and other fields. [0003] Chinese patent CN102127260A discloses a strong and tough long glass fiber reinforced polypropylene composition plate material and its preparation method, using polypropylene, long glass fiber, toughening agent, modified polypropylene, antioxidant and color masterbatch Made by extrusion. Wherein...
