In including the following steps：
（1）Polyamide, makrolon, polypropylene, polyethylene terephthalate, modified hard charcoal are weighed by above-mentioned formula
Black, toughening compositions, fire retardant, nano-titanium dioxide, lubricant, it is spare；
（2）Polyamide, makrolon and polyethylene terephthalate are mixed, is subsequently placed in kneader and is pinched
It closes, control kneading temperature is 140~150 DEG C, and kneading time is 15~25 minutes, obtains the first kneaded material；
（3）By step（2）First kneaded material of gained is cooled to 70~80 DEG C, and polypropylene, nitrile rubber and over-expense is then added
Change polycaprolactone to be mediated, control kneading time is 8~17 minutes, obtains the second kneaded material；
（4）To step（3）Lubricant, modified white carbon black, fire retardant, nanometer titanium dioxide are sequentially added in second kneaded material of gained
Titanium, the process of addition is along with mechanical agitation, after being uniformly mixed, adds zirconium oxide and carbon fiber, and high speed dispersion is uniform,
Up to mixture；
（5）By step（4）The mixture of gained, which is sent into double screw extruder, to be melted, is plasticized, squeezes out, drawing, cooling down, cutting
Grain obtains the engineering plastics for being used for advisement exhibition apparatus after drying.
8. preparation method according to claim 7, which is characterized in that the step（5）The temperature of middle extruder be 240~
260℃。
