Glass fiber reinforced polypropylene material and preparation method thereof

The invention discloses a glass fiber reinforced polypropylene material and a preparation method thereof, and belongs to the technical field of organic materials. The glass fiber reinforced polypropylene material comprises polypropylene copolymer and/or polypropylene homopolymer, compatilizer, glass fibers, antioxidant, light stabilizer and lubricating agent. The preparation method of the glass fiber reinforced polypropylene material comprises the following steps of: 1) weighing; 2) mixing; and 3) performing melt extrusion, drawing and granulating. The invention has the advantages that: 1) the prepared composite material has excellent hydrolysis resistance and high thermal oxidation resistance; 2) the prepared composite material has good mechanical property, and is suitable to be used as a drum washing machine material; 3) the preparation process is simple, and the glass fiber content is easily controlled; and 4) the anti-ageing time (warm water 800H + thermal ageing) of the prepared composite material meets the using requirement of a drum washing machine.
