Abstract

The invention relates to the technical field of research and development and processing of fishing tools, in particular to a preparation method of modified chitosan-based bionic fish baits. The preparation method of the modified chitosan-based bionic fish baits, provided by the invention, has the benefits that the modified chitosan-based bionic fish baits are prepared by taking a modified chitosanacetic acid solution as a base material, taking modified corn starch and glass fibers as modifying agents and supplementing with stannous octoate, allicin and the like; firstly the modified chitosanacetic acid solution is prepared by taking shrimp shells as a raw material, then glass fibers are added in the base material, and the base material transfers stress among the glass fibers, so that thestrengths of the bionic fish baits are improved; the corn starch is simply treated with ammonium persulfate and acrylic acid, so that the enhancement in the dependence between the modified corn starch and the base material in a whole system is promoted; the corn starch is modified by utilizing a homemade dihydrosalicylate crystal; a benzene ring is introduced in a corn starch main chain after modification, the mechanical properties of the corn starch are improved; and in addition, the corn starch has excellent biodegradability, has no pollution to an environment and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of research, development and processing of fishing gear, in particular to a preparation method of a modified chitosan-based bionic fishing bait. Background technique [0002] As everyone knows, along with the raising of people's economic level, fishing is very popular among modern people as an outdoor activity. In traditional fishing, in order to lure fish to take the bait, different baits are generally placed on the hook at the end of the hook line according to the different fish. When the bait is swallowed, the fish will take the bait. Easy to slip off. With the development of society, people's awareness of environmental protection has gradually improved, and they gradually realized that traditional fishing baits will cause certain pollution to the environment. [0003] In recent years, artificial bionic baits have been used more and more widely. The bionic bait is manufactured using the law of "big fis...
