Abstract

The invention discloses starch-based biodegradable bionic bait added with modified nano calcium carbonate. A preparation method of the starch-based biodegradable bionic bait includes: evenly dispersing high hydrophobic modified dialdehyde starch in distilled water, heating for gelatinization, adding polylactic acid, polyvinyl alcohol and plasticizer glycerin, sufficiently mechanically evenly stirring and mixing, adding preprocessed jute fibers, high-speed stirring modified nano calcium carbonate, stirring, and adding into a single-screw extruder to prepare master batch; evenly pacing the master batch into a mould of the bionic bait, prepressing the mould in a plate vulcanizing machine, and performing hot-press molding. The high hydrophobic modified dialdehyde starch, the polylactic acid and the polyvinyl alcohol are used as the raw materials, the modified nano calcium carbonate and the preprocessed jute fibers are added, and the starch-based biodegradable bionic bait is prepared through the compounding of the materials above; by adding the jute fibers which has a lot of hydroxyl on the surface, the blending compatibility of the dialdehyde starch and polyvinyl alcohol can be increased, and mechanical performance is increased while the water resistance of the bait is increased.

Description

technical field [0001] The invention belongs to the field of bionic fishing bait, in particular to a starch-based biodegradable bionic fishing bait added with modified nano-calcium carbonate. Background technique [0002] Starch is a polysaccharide compound, which is a natural polymer material with a wide range of sources. Starch has a wide range of applications in textiles, papermaking, and petroleum industries. Since the 1960s, with the dwindling of the earth's oil resources and the gradual aggravation of environmental degradation caused by plastic white pollution, biodegradable plastics have been favored by research at home and abroad. Due to the good biodegradability of starch, the research on biomass as a biodegradable plastic has achieved certain results. However, the inherent polyhydroxyl structure of native starch makes it highly polar, resulting in poor compatibility between starch and non-polar or weakly polar synthetic resins, which limits its application in biod...
