further, the fumed silica has an average particle size of 7-40nm and a specific surface area of 150-380m2/g；
Further, the carbon fiber is filament carbon fiber with monofilament diameter of 6-20 μm or short filament with length of 0.5-3cm or mixture of the two;
further, the glass fiber is filament glass fiber with the diameter of 6-17 μm or short filament with the length of 0.5-3cm or the mixture of the two;
further, the anti-aging mildew-proof nylon comprises the following components in parts by weight:
6670 parts of nylon;
10 parts of long carbon chain nylon;
8 parts of ethylene propylene diene monomer and maleic anhydride graft copolymer (EPDM-g-MAH);
0.6 part of fumed silica;
10 parts of carbon fiber
25 parts of glass fiber;
0.5 part of a lubricant;
0.6 part of anti-aging agent;
0.5 part of interfacial compatilizer;
0.5 part of bismuth vanadate;
1.5 parts of a mildew preventive.
Further, the mildew preventive is a mixture of thiabendazole, cuprous oxide and zinc borate, and the mass ratio of the mildew preventive to the mixture is 0.5: 0.1-1: 1.
Further, the preparation method of the anti-aging mildew-proof nylon is characterized by comprising the following steps:
weighing raw materials of nylon 66, long-carbon-chain nylon, ethylene propylene diene monomer, maleic anhydride graft copolymer, lubricant and anti-aging agent according to a ratio, adding the raw materials into a high-speed stirrer, stirring for 2-3 minutes, discharging, and adding into a main feeding metering hopper of a double-screw extruder;
weighing thiabendazole, fumed silica, cuprous oxide, zinc borate and bismuth vanadate according to the proportion. Thiabendazole was added to acetone and stirred until completely dissolved. Sequentially adding fumed silica and acetone dissolved with thiabendazole into a high-speed stirrer, setting the temperature to be 55 ℃, stirring at low speed for 2-3 minutes, then adding cuprous oxide, zinc borate and bismuth vanadate, setting the temperature to be 80 ℃, adding an interface compatilizer, stirring at high speed for 3-5 minutes, discharging, and adding another metering hopper of a main feeding hopper of a double-screw extruder;

The bismuth vanadate has synergistic effect with the mildew preventive and has synergistic effect with the anti-aging agent, and the addition of the bismuth vanadate obviously improves the anti-aging performance of a material system. The method adopts acetone to treat thiabendazole and pre-mixes the thiabendazole with fumed silica at 55 ℃ to fully disperse the organic mildew inhibitor thiabendazole into the porous structure of the fumed silica to play a role of slow release.
