The present invention relates to a low water absorption glass fiber reinforced PA material and its preparation method, comprising 50-90 parts of high amino PA resin; 5-10 parts of polyvinylidene fluoride grafted with maleic anhydride; 5-40 parts of chopped glass fiber; 0.1-1 part of auxiliary agent, prepared by mixing high amino PA resin, polyvinylidene fluoride grafted maleic anhydride, and auxiliary agent evenly, adding them through the main feeding port of the twin-screw extruder, and adding short cut glass fibers through the feeding port on the extruder side for extrusion granulation to obtain the low water absorption glass fiber reinforced PA material. Compared with existing technologies, the material of the present invention has high rigidity, low water absorption rate, and small deformation. It can be widely used in plastic products with rigid and dimensional requirements such as small household appliance casings and automotive interior and exterior decorations, and has broad application prospects.
