Problems solved by technology

[0013] Because fishing baits need to have a good bionic effect in water, high-toughness materials similar to elastomers must be used to meet this requirement. Therefore, some rigid PHAs structures similar to PLA, such as those composed of 3-hydroxybutyric acid Poly 3-hydroxybutyrate P (3HB) can not meet the use requirements

Embodiment 1

[0055] Weigh 100kg of P3HB4HB (40% 4HB), 0.5kg of cod liver oil, 0.3kg of natural essence, and 0.2kg of food coloring, stir in a mixer at room temperature for 5 minutes to obtain a raw material mixture of fully biodegradable plastics. Place the stirred mixture in an electric blast drying oven at 60°C for 10 hours, and then extrude the above-mentioned dried mixture with a 45 twin-screw extruder with a length-to-diameter ratio of 28:1, and the die temperature is 115 ℃, direct granulation after extrusion to obtain a fully biodegradable plastic masterbatch. Biodegradable artificial fishing baits are obtained from the masterbatch by injection molding or molding.

Embodiment 2

[0057] Weigh 80kg P3HB4HB (45% 4HB) and 20kg PHBV (20% HV) and 0.2kg silkworm chrysalis powder, 0.2kg honey, 0.2kg rice wine, 0.2kg food coloring, stir at room temperature in a mixer for 8 minutes to obtain the raw materials of fully biodegradable plastics Mixture. Place the stirred mixture in an electric blast drying oven at 65°C for 10 hours, and then extrude the above-mentioned dried mixture with a 45 twin-screw extruder with a length-to-diameter ratio of 28:1, and the die temperature is 130 ℃, direct granulation after extrusion to obtain a fully biodegradable plastic masterbatch. Biodegradable artificial fishing baits are obtained from the masterbatch by injection molding or molding.

Embodiment 3

[0059] Weigh 80kg of P3HB4HB (40% 4HB), 10kg each of PCL and PBS, and 0.3kg of shrimp meal, 0.2kg of fish meal, 0.5kg of fish oil, and 0.2kg of natural pigment, stir in a mixer at room temperature for 10 minutes to obtain a raw material mixture of fully biodegradable plastics . Place the stirred mixture in an electric blast drying oven at 65°C for 10 hours, then extrude the above dried mixture with a 45 twin-screw extruder with a length-to-diameter ratio of 28:1, and the die temperature is 120 ℃, direct granulation after extrusion to obtain a fully biodegradable plastic masterbatch. Biodegradable artificial fishing baits are obtained from the masterbatch by injection molding or molding.

Abstract

The invention relates to a biodegradable synthetic bait and a preparation method thereof. The bait comprises main material including PHAs, PCL, PBS, APC or natural elastic material or petroleum base elastic material, accessory ingredient, fish attrahent, colorant, and the like, wherein the PHAs comprise monomer, multipolymer and mixture of monomer and multipolymer in the PHAs familiy. The mixed material has proper material density and ideal toughness and resistance to elements. The novel biodegradable material can be made into synthetic biodegradable fish bait through injection molding or mould pressing, has favorable simulated effect and is a good substitute for prior artificial bait material.

Description

technical field [0001] The present invention relates to the technical field of an artificial biodegradable fake fishing bait, especially relates to the use of degradable materials as the main material of the fishing bait. This fake fishing bait can be degraded in the environment and in vivo without causing harm to the environment. It also relates to methods of using these materials to make artificial lures. Background technique [0002] Due to the increasing scarcity of petroleum resources and the pressure on the environment, as well as safety considerations, people have begun to pay more and more attention to the application of degradable materials, especially in some special fields. Articles made of materials that can cause significant harmful or deleterious effects. This is especially true for the marine environment. More and more reports have shown that even very small non-degradable items, such as artificial polymer fake fishing baits, will have adverse effects on the ...
