The invention discloses a fishing net prepared from ceramic powder-modified plastic. The fishing net is prepared from the following components: methyl laurate, a nylon 6 and polyvinylidene chloride mixture, polyethylene, ceramic powder, polyethylene terephthalate, medium vinyl polybutadiene rubber, polypropylene fiber, aluminum oxide powder, rosin and an assistant modifier. By combination of the advantages of the raw materials of the nylon and polyvinylidene chloride mixture, the polyethylene and the like, modified treatment is carried out by the ceramic powder as the material; auxiliary modified treatment is carried out on the raw materials by the raw materials of the aluminum oxide powder, the rosin, the assistant modifier and the like; the improved material has good mechanical property; the prepared fishing net has high strength, good tenacity and high impact resistance; the bending strength is greatly improved; especially, the tensile strength and the weather resistance are greatly improved; the service lifetime of the fishing net is 1.5 times that of an ordinary fishing net in the same complicated environment; and the tensile strength is 0.8 times that of the ordinary fishing net.
