The invention discloses a
glass fiber toughened and reinforced nylon 6
composite material, a preparation method and application thereof, wherein the
glass fiber toughened and reinforced nylon 6
composite material comprises, in parts by weight, 50 parts to 75 parts of a PA6 resin, 20 parts to 40 parts of an alkali-free
glass fiber, 1 part to 8 parts of a graft
elastomer, 1 part to 3 parts of a grafted
polyolefin, 0.1 to 1.2 parts of a glass
fiber dispersant and 0.1 parts to 0.6 parts of an anti-oxidant. This
composite material is prepared by a twin-screw extruder and also used for automobile cooling fans. The invention has the following advantages that this composite material has excellent mechanical properties, and excellent high, low
temperature resistance performance. Besides, this invention ensures the uniform distribution of the material composition, particularly for glass
fiber which is uniformly distributed in a matrix resin(PA6), which solves the problems of uneven distribution and
exposure of the glass
fiber. Therefore the fans made from this material have excellent
dynamic balance performance, brightening surfaces and no glass fiber flow line and
exposure.
