Problems solved by technology

[0002] With the development of fishery, in order to improve the performance of fishing nets, polyethylene and nylon are mainly used for processing, which increases the service life and strength of fishing nets accordingly, but the mechanical properties of nylon fishing nets are average, and the creep resistance is not good. , resulting in the fishing nets being unsuitable for fishing operations in complex seabed and high wind and waves environment, especially in complex seabed operations, the friction between the fishing net and seawater will intensify, and if things go on like this, the fishing net will be seriously worn, which will directly lead to the fishing net being more likely to break, unable to continue to operate, and shorten the life span

Abstract

The invention discloses a copolymer reinforced nylon wear-resistant fishing net. The fishing net is made from nylon 6 modified through the coordination of a methyl methacrylate-maleic anhydride copolymer and nano-silica microspheres. The methyl methacrylate-maleic anhydride copolymer and the nano-silica microspheres are coordinated in nylon 6 modification, the frictional wear and the erosion resistance of the fishing net can be improved, and meanwhile the existence of the nano-silica microspheres can improve the thermal stability and the friction creep resistance of the fishing net to a certain extent.
