The invention relates to a low-floating-
fiber glass fiber reinforced
polypropylene material and a preparation method thereof. The low-floating-
fiber glass fiber reinforced
polypropylene material is prepared from, by weight, 100 parts of
polypropylene resin, 15-30 parts of high-melt-strength polypropylene, 10-50 parts of
glass fiber, 1-3 parts of a compatilizer, 5-15 parts of an
ethylene-propylene segmented
copolymer and 1-2 parts of other auxiliaries. According to the preparation method of the low-floating-
fiber glass fiber reinforced polypropylene material, screw
extrusion processing is adopted, and the screw combination design principle is adopted, wherein the first region and the second region are only composed of conveying components, the third, fourth, fifth, sixth and seventh regions comprise shearing components, the eighth, ninth and tenth regions are composed of conveying components, and the
extrusion temperature is 165-230 DEG C. According to the low-floating-
fiber glass fiber reinforced polypropylene material, the
mechanical property is excellent, and the surface of the obtained low-floating-
fiber glass fiber reinforced polypropylene material is smooth, clean and free of floating fiber.
