Abstract

The invention discloses a high-toughness bionic bait and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing modified polycaprolactone, a modified toughening agent, a phagostimulant, a pigment, an antioxidant, a calcium-zinc stabilizer and a lubricating agent in a high-speed mixer to obtain a blend, adding the obtained blend into a hopper of a double-screw extruder, carrying out melt extrusion, bracing, cooling, pelletizing and drying to obtain blended material particles. The interaction between the esterified sodium lignin sulfonate and the polycaprolactone is stronger, the sodium lignin sulfonate is more uniformly distributed in the polycaprolactone, and the hydroxyl group of the sodium lignin sulfonate and the polycaprolactone molecule form a hydrogen bond, so that the mechanical property of the molecule is enhanced; the polycaprolactone and the lignin are completely degraded after being subjected to demethylation, demethoxylation, side chain oxidation and aromatic ring opening under the action of microorganisms, so that the aim of protecting the environment is fulfilled.

Description

technical field [0001] The invention relates to the field of bionic bait, in particular to a bionic bait with high toughness and a preparation method thereof. Background technique [0002] Fishing with bionic bait is a very popular way of fishing. Food bait or synthetic bait will dissolve and fall off in water. It is necessary to change new bait on the hook frequently, which is inconvenient to use. Bionic bait uses "big fish eat Manufactured according to the law of "little fish", it can float in the water by using its own buoyancy and the traction of the hook line. The hook on the bionic bait is very lethal. Once the fish bites the hook, it is difficult to escape. It has the characteristics of no need to change bait for long-term use. ; [0003] However, the existing bionic baits have poor toughness. During the fishing process, due to improper use or exposure to sunlight, the material is brittle and prone to deformation and fracture, resulting in a shortened service life, a...
