The invention discloses a hydrolysis and alcoholysis-resisting reinforced nylon material. The hydrolysis and alcoholysis-resisting reinforced nylon material is prepared from the following raw materials of nylon resin, a reinforced material and an anti-degradation assistant, wherein the anti-degradation assistant is prepared from N,N'-bis(2,2,6,6-tetramethyl-4-piperidyl)-1,3-phthalic diamide benzendicarboxamide and an anti-aging agent through compounding; the nylon resin is selected from at least one of PA66, PA610 and PA612. According to the hydrolysis and alcoholysis-resisting reinforced nylon material provided by the invention, a compounded anti-degradation assistant system is adopted, so that hydrolysis and alcoholysis resistance of a composite material can be increased; meanwhile, excellent processing temperature resistance is obtained, and the hydrolysis and alcoholysis-resisting reinforced nylon material is particularly suitable for carrying out injection molding processing on large-scale pieces such as an automobile radiator cooling water tank, a thermostat, an intercooler and the like.
