Embodiment Construction
[0015] The technical scheme of the present invention will be further described below in conjunction with specific examples:
[0016] A fishhook with a high specific gravity that can be injection molded with a tungsten head is characterized in that tungsten powder is used as a base material, polylactic acid and nylon are melted and blended, the fishhook is put into a mold, and finally the fishhook with a high specific gravity is injection molded. The parts by weight of each raw material are 90 parts of tungsten powder, 8 parts of nylon powder, and 5 parts of polylactic acid.
[0017] The preparation method comprises the following steps:
[0018] Mix tungsten powder and polylactic acid evenly, then add it to the molten nylon, mix evenly, inject it into the mold cavity with the fishhook, and cool it to shape.
[0019] The density of the counterweight material obtained is 10-13g / cm 3 .
[0020] The schematic diagram of the resulting high specific gravity tungsten head fishhook ...
