Problems solved by technology

On the one hand, the bionic fishing bait produced by this method will increase the production cost due to the addition of polycaprolactone, a biodegradable material, and on the other hand, the full biodegradability of polylactic acid will be destroyed due to the addition of TPEE thermoplastic elastomer.
[0004] In addition, the color of the existing bionic bait made of polylactic acid is not bright enough, and the color stability is not high, and this problem will reduce the intensity of attracting fish and affect the fishing effect, and further improvement is also needed

Embodiment 1

[0032] A preparation method of a brightly colored and stable bionic bait, comprising the steps of:

[0033] (1) Preparation of modified polylactic acid:

[0034] 1) Mix terephthalic acid and ethylene glycol into the reactor according to the molar ratio of 1:1.4, heat to keep the temperature in the reactor at 200°C, and keep stirring until the degree of esterification is more than 50%, and then add Put a composite filler with 8% of the total mass of the material in the reaction kettle, and continue to stir for treatment. When the degree of esterification is above 90%, add antimony trioxide catalyst, and raise the temperature in the reaction kettle to 290°C, and vacuumize at the same time. , take out the mixture after 2h for subsequent use;

[0035] 2) Put the mixture prepared in operation 1) into the extruder, extrude and granulate, and take out the modified polylactic acid after completion;

[0036] (2) Raw materials are weighed for backup:

[0037] Weigh the following raw ...

Embodiment 2

[0054] A preparation method of a brightly colored and stable bionic bait, comprising the steps of:

[0055] (1) Preparation of modified polylactic acid:

[0056] 1) Put terephthalic acid and ethylene glycol into the reactor according to the molar ratio of 1:1.6, heat to keep the temperature in the reactor at 220°C, and keep stirring until the degree of esterification exceeds 50%, and then add Put the composite filler with 10% of the total mass of the material in the reaction kettle, and continue to stir the treatment. When the degree of esterification is above 90%, add antimony trioxide catalyst, and raise the temperature in the reaction kettle to 310 ° C, and vacuumize at the same time , After 2.2h, take out the mixture for later use;

[0057] 2) Put the mixture prepared in operation 1) into the extruder, extrude and granulate, and take out the modified polylactic acid after completion;

[0058] (2) Raw materials are weighed for backup:

Abstract

The invention discloses a method for preparing a bionic bait having a bright and stable color. The method comprises the following steps: (1) preparing modified polylactic acid; (2) weighing raw materials for later use; and (3) preparing a finished product. The method is simple in process and reasonable in step matching, is convenient for batch production and processing; and the bionic bait has good temperature resistance, high mechanical strength and good and stable color condition. The effect for attracting fish is improved, so that the method has great market competitiveness and popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of bionic fishing bait processing, and in particular relates to a method for preparing bionic fishing bait with bright and stable colors. 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. Polylactic acid (PLA) is a biodegradable polymer material...
