Problems solved by technology

[0005] (1) By dissolving sodium periodate in distilled water, adding cornstarch, drying to obtain intermediate A, pulverizing jute fiber, stirring with sodium hydroxide solution at room temperature, washing, centrifuging, and drying to obtain intermediate B, intermediate Add A into distilled water, add boric acid as a cross-linking agent, then add intermediate B and palygorskite clay, cool to obtain the modified polyvinyl alcohol, and solve the problem by adding the modified polyvinyl alcohol to the bionic bait. The existing bionic baits degrade slowly or even cannot be degraded, resulting in environmental pollution;

Abstract

The invention discloses a full-biodegradable bionic bait and a preparation method thereof.The preparation method comprises the following steps: uniformly mixing modified polyvinyl alcohol, modified nano calcium carbonate, a phagostimulant, a pigment, an antioxidant, citrate and a lubricant in a high-speed mixer to obtain a blended material, adding the obtained blended material into a hopper of a double-screw extruder, and carrying out melt extrusion, drawing, cooling, pelletizing and drying to obtain modified polyvinyl alcohol particles. The addition of the starch can accelerate the degradation of the polyvinyl alcohol on one hand, and can reduce the cost of the bionic bait on the other hand, and the addition of the fibers can improve the water resistance, biodegradability and environment-friendly degree of the material, thereby achieving the purposes of improving the degradation speed of the bionic bait and protecting the environment.

Description

technical field [0001] The invention relates to the field of bionic fishing baits, in particular to a fully biodegradable bionic fishing bait and a preparation method thereof. Background technique [0002] The existing bionic baits are mostly made of high-strength plastics, which degrade slowly or even cannot be degraded. If the bait falls into the water, it will cause environmental pollution, and it will cause great harm to the fish after being swallowed by fish, and some of them are degradable. The inherent polyhydric structure of the material itself makes it highly polar and poor in mutual compatibility, which limits its application in biodegradable plastics; [0003] Therefore, how to improve the environmental pollution and poor mutual compatibility caused by the slow degradation rate or even inability to degrade the existing bionic bait is the problem to be solved by the present invention. Contents of the invention [0004] In order to overcome the above technical pr...
