Problems solved by technology

However, due to the slow crystallization speed of pure polylactic acid resin, large shrinkage rate of molded products, poor dimensional stability, brittle material itself, poor processing thermal stability, etc., its application is limited; while PVC has relatively good overall performance, but its degradation Poor, polylactic acid and PVC each have advantages and disadvantages, although there is a combination of the two in the prior art, after the combination of the two, the compatibility is poor and the dispersion is general, resulting in the performance of the plastic product made Significantly reduced, unable to meet market demand

Abstract

The invention discloses degradable environment-friendly bionic bait and relates to the technical field of bionic bait. The degradable environment-friendly bionic bait is prepared from the following ingredients of PVC resin, polylactic resin, alkali treated bamboo fiber, cross-linking sodium carboxymethylcellulose, a plasticizer, a coupling agent and filler. Therefore, physical mechanical performance of the prepared bionic bait is improved; furthermore, the degradable environment-friendly bionic bait further can have good degradability, quick degradation velocity and high degradation degree; thus, the whole degradation effect on the bionic bait can be achieved through destructive effects on chemical bonds in the polylactic acid, the cross-linking sodium carboxymethylcellulose and the calcium carbonate.

Description

technical field [0001] The invention belongs to the technical field of bionic fishing bait, and in particular relates to a degradable and environment-friendly bionic fishing bait. 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 plastic, which cannot be degraded and is not easy to handle after use. If the bait falls into the sea, it will cause great harm to the fish after being swallowed by the fish, and it will have multiple cycles in the fish food chain, which is extremely harmful. [0003] Polylactic acid, also known as polylactide, belongs to the family of polyesters. Polylactic acid is a polymer obtained by polymerizing lactic acid as the main raw material. The raw material source is sufficient and can be regenerated. The production process of polylactic acid is non-polluting, and the product can be biodegra...
