Novel environment-friendly low-cost long glass fiber reinforced polypropylene composite material and preparation method thereof

The invention discloses a novel environment-friendly low-cost long glass fiber reinforced polypropylene composite material and a preparation method thereof. A formula for the composite material is prepared from the following components in parts by weight: 15 to 30 parts of regenerated polypropylene resin, 35 to 65 parts of conventional polypropylene resin, 20 to 30 parts of glass fibers, 1 to 3 parts of a compatilizer, 1 to 2 parts of carbon black master batch, 0.5 to 1.5 parts of an antioxidant, 0.5 to 1.5 parts of a light-resistant additive and 0.03 to 0.05 part of essence. Compared with common long glass fiber reinforced materials of the same trademark on the market, the long glass fiber reinforced polypropylene composite material prepared by the invention has the advantages that the basic raw materials contain certain regenerated polypropylene resin, so production cost is reduced, and meanwhile, the mainstream concept of low carbon and environment friendliness on the market is accorded with.
