The invention provides a polyamide material with functions of antibiosis and aging resistance, which comprises the following raw materials in percent by weight: 70 percent to 90 percent of polyamide, 3 percent to 5.5 percent of plant source extract, 5 percent to 18 percent of nano loess, 1.2 percent to 3 percent of herpetospermum caudigerum wall seed oil, 0.3 percent to 1.5 percent of myristyl hydroxyethyl amino oxide, and 0.5 percent to 2 percent of coupling agent. Thereby, the polyamide material has multiple functions of natural antibiosis, mould proof, oxidation resistance, ultraviolet protection, and far infrared health care through various processing means, reasonable complex formulation, and synergistic interaction. The polyamide material is used for making a polyamide product, wide in antibacterial spectrum, high in bacteriostatic ability and durable in antibacterial effect. Additionally, the aging resistance and mechanical performance properties are better, and the polyamide material is not discolored, not deformed, embrittled under sun exposure for a long term, so the service life is long. Meanwhile, a far infrared effect also has the functions of self cleaning, purifying ambient air, and eliminating peculiar smell, is beneficial to human health and environmental friendly, and the application range of the polyamide material is greatly expanded.
