Problems solved by technology

Although the bionic bait has a certain degree of biodegradability, there are still many mixed PVC resins, which will affect the decomposition rate and completeness of decomposition, and the inorganic fillers in it are difficult to disperse evenly, which will affect the mechanical properties and softness of the bait material. sex

preparation example Construction

[0039] The preparation method of the bionic bait comprises the following steps:

[0040] The first step is to weigh the raw materials according to the weight ratio, mix the modified polylactic acid and the elastomer, banbury for 20-30min at 180°C and 100r / min, take it out, crush it, and cool it to obtain the premix thing;

[0041] In the second step, the premix and antioxidant are added to the twin-screw extruder, melt-extruded, drawn, cooled, pelletized and dried to obtain a composite material for use;

[0042] The third step is to press the composite material obtained in the first step into the mold cavity of the injection molding machine mold by using the screw of the injection molding machine. After molding, cooling and shaping, it is made into the desired shape of the bait to obtain the bionic bait.

Embodiment 1

[0044] A soft and environment-friendly bionic bait comprises the following raw materials in parts by weight: 50 parts of modified polylactic acid, 8 parts of elastomer, and 0.5 part of antioxidant.

Embodiment 2

[0046] A soft and environment-friendly bionic fishing bait comprises the following raw materials in parts by weight: 55 parts of modified polylactic acid, 9 parts of elastomer, and 0.6 part of antioxidant.

Abstract

The invention discloses a soft environment-friendly bionic bait composed of the following raw materials in parts by weight: 50 to 60 parts of modified polylactic acid, 8 to 10 parts of an elastomer and 0.5 to 0.7 part of an antioxidant, wherein the bionic bait is prepared by the following steps: step 1, internally mixing modified polylactic acid and an elastomer; step 2, blending and granulating;and step 3, carrying out injection molding and compression molding. The modified polylactic acid is used as a polymer matrix of the bionic bait; polylactic acid is subjected to graft modification through a modifier, a -S+(CH3)2 structure is introduced into the obtained polylactic acid, effective components for luring fishes are combined with the polylactic acid through bonding, the release rate ofa fish luring agent in seawater is reduced, the service life of the bionic bait is prolonged, and the modified polylactic acid has good biodegradability; in addition, the polylactic acid is toughenedby adopting the elastomer, so that a bait material has good flexibility; the preparation method is simple, the effect of the finished product is remarkable, the softness and the biodegradability aregood, and the environmental pollution is small.

Description

technical field [0001] The invention belongs to the field of bionic fishing bait production, and in particular relates to a soft and environment-friendly bionic fishing bait and a preparation method thereof. Background technique [0002] Bionic bait has a good market in the current fishing gear market, and it has a good fishing effect on relatively fierce fish. The current bionic bait is mostly made of high-strength plastics, such as PVC, PE, PC, ABS and other plastics. , cannot be degraded, and it is not easy to handle after use, especially if the bait falls into the sea, it will cause great harm to the fish after being swallowed by the fish, and it will cycle many times in the fish food chain, which is extremely harmful. Yet plastic bionic baits commonly used mostly are to be prepared with non-degradable plastics. Therefore, the development of biodegradable bionic bait materials is of great significance to environmental protection. [0003] The Chinese invention patent w...
