Technical Field

The invention belongs to the technical field of fishing tools, and particularly relates to degradable bionic bait prepared from modified plastic.

Background

In recent years, the application of artificial bionic bait is more and more extensive. The bionic bait is manufactured by utilizing the law that big fishes eat small fishes, and can float in water by utilizing the buoyancy of the bionic bait and the traction of a hook line. The fish hook on the bionic bait has strong killing power, the fish is difficult to escape once biting, and compared with the traditional bait, the bait omits the procedure of preparing the bait, thereby being popular with consumers.

At present, the bionic bait sold in the market is good in fishing effect, but is made of plastics with high strength, the degradation speed is very slow, and even the bionic bait cannot be degraded, the bait can cause environmental pollution after falling into water, and the bait is phagocytosed by fishes and then can cause great harm to the fishes.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides degradable bionic bait prepared by using modified plastics.

In order to achieve the purpose, the invention adopts the following technical scheme:

a degradable bionic bait prepared from modified plastics comprises: bait, bait is the cavity structure, bait is the frog shape, bait's mouth is equipped with an depressed part, be equipped with the go-between in the depressed part, the silk thread connection of go-between and fishing rod, bait's afterbody is equipped with the fishhook, the fishhook arranges and the pointed end of fishhook towards the mouth along bait's back, still be equipped with the counterweight between bait's belly and the afterbody, the inside support frame that still is equipped with of bait, the support frame is three branches component space coordinate system structure, and the extreme point end to end of its three branches constitutes a plurality of triangles.

The bait body is prepared from modified plastics, and the modified plastics are modified polyethylene.

The preparation method of the degradable bionic bait prepared by using the modified plastic comprises the following steps:

(1) preparing modified polyethylene: adding high-density polyethylene, calcium carbonate, glucomannan, corn starch and a foaming agent into a mixer, uniformly mixing to obtain a raw material mixture, feeding the raw material mixture into a double-screw extruder, and carrying out melt extrusion, cooling and grain cutting to obtain modified polyethylene particles;

(2) preparing the bionic bait: placing the particles obtained in the step (1) into an injection molding machine for injection molding to obtain the bionic bait with the required shape;

(3) polishing and coloring: and (3) polishing the bionic bait obtained in the step (2), and coloring after polishing.

The total amount of the raw material mixture is 100 parts by weight, wherein the high-density polyethylene accounts for 54-65 parts by weight, the calcium carbonate accounts for 5-25 parts by weight, the glucomannan accounts for 2-10 parts by weight, the corn starch accounts for 1-8 parts by weight, and the foaming agent accounts for 1-3 parts by weight.

The density of the high-density polyethylene is 0.940-0.976 g/cm 3.

The extrusion temperature of the double-screw extruder in the step (1) is 190-220 ℃, and the rotating speed of the double-screw extruder in the step (1) is 200-350 rpm.

And (3) the injection molding temperature of the injection molding machine in the step (2) is 170-180 ℃, the injection molding pressure is 80-100 MPa, the pressure maintaining time is 30-60 s, and the preheating temperature of the mold cavity is 80-90 ℃.

The pigment used for coloring in the step (3) is a plant extracted pigment.

Compared with the prior art, the invention has the following technical effects:

(1) in the invention, the support frame is additionally arranged in the bait body, so that the bait body can be prevented from deforming under water due to pressure, the fishing success rate is reduced, and in addition, each surface of the support frame is in a triangular shape, so that the bait has good stability.

(2) In the invention, polyethylene is modified to have degradability, and meanwhile, because glucomannan is added in the polyethylene modification process, the toughness of the modified polyethylene is effectively improved, so that the toughness of the bionic bait prepared by using the modified polyethylene is improved, and in addition, the glucomannan used as a raw material is easy to degrade, thereby avoiding pollution to the environment;

(3) in the invention, the foaming agent is added into the polyethylene modified raw material, so that calcium carbonate in the foaming agent can be uniformly dispersed in the modified polyethylene raw material in the foaming process, and then the calcium carbonate can form gaps which cannot be seen by naked eyes on the surface of the modified polyethylene, so that the bionic bait made of the modified polyethylene has oil absorption, and patterns or characters can be printed on the surface of the bionic bait.

Additional features and advantages of the invention will be set forth in the detailed description which follows.
