[0020] Example 1
[0021] The parts by weight of each component are: 35 parts of component A, 50 parts of component B, 15 parts of component C, 1 part of polyphosphate, and 1 part of orthophosphate. Weigh all kinds of materials except flat glass fibers according to the above component proportions. After high-speed mixing, they are melted and extruded with the side-fed flat glass fibers through a twin-screw extruder, and then cut into pellets by a granulator to produce The pellets were dried in an oven at 120 °C for 4 hours, and then obtained by injection molding by an injection molding machine; the temperature of the extruder was set to 260-290 °C, the temperature of the injection molding machine was set to 280-310 °C, and the injection pressure was 70-120 bar.
[0022] The tensile strength of the nylon material prepared in this example is 240-270Mpa, the bending strength is 360-400Mpa, the bending modulus is 13000-18000Mpa, and the impact strength is 10-20KJ / m 2 , the appare...
