Abstract

The invention relates to fully biodegradable bionic bait and a preparation method thereof and belongs to the field of a high polymer material. The fully biodegradable bionic bait is prepared from components in parts by weight as follows: 99-80 parts of polylactic acid, 1-20 parts of a flexibilizer, 0.01-10 parts of an activating agent, 0.05-2 parts of a catalyst, 0.1-5 parts of a nucleating agent, 0.01-5 parts of a phagostimulant, 0-3 parts of a pigment, 0-1 part of an antioxidant and 0-1 part of a lubricant. The preparation method comprises steps as follows: the uniformly mixed materials are added to a hopper of a double-screw extruder, a ratio of the injection volume of the flexibilizer to the weight of polylactic acid is controlled to be (1:99)-(20:80), the materials are subjected to melting extrusion, bracing, cooling, grain-sized dicing and drying, and modified polylactic acid particles are obtained; the modified polylactic acid particles are subjected to injection molding on an injection molding machine, and the fully biodegradable bionic bait in a required shape is obtained. The extrusion temperature of the double-screw extruder is 140-190 DEG C, a length-diameter ratio L/D of screws is (44:1)-(64:1), and the screw speed is 80 rpm-360 rpm; besides, the injection molding temperature of the injection molding machine is 130-200 DEG C, the injection molding pressure is 50-120 MPa, the pressure maintaining time is 5-300 s, and the mold temperature is 60-120 DEG C.

Description

technical field [0001] The invention relates to the field of preparation of polymer materials, in particular to a fully biodegradable bionic bait and a preparation method thereof. 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. The bionic bait made of plastic for fishing has the effects of lifelike bionic fish, shrimp, insects, etc., and can be used for a long time without changing bait. It is widely used among fishing enthusiasts. Yet the plastic bionic bait commonly used mostly is to be prepared with non-degradable plastics, as adopts plastics such as PVC, PE, PC, ABS. Once the bionic bait made of this kind of plastic falls off and falls into the ocean, it cannot be degraded for hundreds of years, which will cause great harm to marine life and the ecological environment. [0003] Polylactic acid (PLA) is a biodegradable polymer material made from starch...
