Method for preparing trimeric high-strength and high-toughness energy-saving fishing net

Abstract

The invention discloses a method for preparing a trimeric high-strength and high-toughness energy-saving fishing net, which is implemented by carrying out synthesis on polyethylene (1), polypropylene (2), polyamides (3), Nano silicon dioxide (4), polyethylene wax (5), a coupling/bulking agent (6), a UV (ultraviolet) resistant agent 173 (7), a coloring agent (8) and white mineral oil (9) accordingto five steps (namely, a step A, a step B, a step C, a step D and a step E).

Description

Technical field: [0001] The invention relates to a preparation method of an energy-saving fishing net. Background technique: [0002] The traditional polyethylene fishing net is an ordinary fishing net made of polyethylene material through melt plasticization, spinning, ply twisting, and weaving. It is used for marine trawls, purse seines, wind-resistant sea cages, etc.; It is still limited by the performance of the existing fishery HDPE material. Its strength and wear resistance are not suitable for fishing operations in complex seabeds and strong winds and waves. It is difficult to further improve the fishing efficiency of fishing nets, trawl nets, and seine nets, which will directly affect the catch. [0003] In order to improve the service life of fishing gear, if simply increasing the thickness of the net line, the weight of the net gear will increase significantly, and finally the diesel consumption of the tugboat will increase by more than 15%, and the cost of fishin...

[0002] The traditional polyethylene fishing net is an ordinary fishing net made of polyethylene material through melt plasticization, spinning, ply twisting, and weaving. It is used for marine trawls, purse seines, wind-resistant sea cages, etc.; It is still limited by the performance of the existing fishery HDPE material. Its strength and wear resistance are not suitable for fishing operations in complex seabeds and strong winds and waves. , trawl, and seine fishing efficiency are difficult to further improve, which directly affects the catch

[0003] In order to improve the service life of fishing gear, if simply increasing the thickness of the net line, the weight of the net gear will increase significantly, and finally the diesel consumption of the tugboat will increase by more than 15%, and the cost of fishing will rise sharply

[0004] At present, my country has begun to produce ultra-high molecular polyethylene (UHMWPE) fibers, and has begun to test the production of UHMWPE ultra-high molecular polyethylene fishing nets. Although the strength of the net rope is 3.5-4 times that of ordinary HDPE, the nets are due to traditional methods. Manufacturing, the knot strength of the net gear is only doubled, and the price is more than 10 times higher than the traditional net gear, and the manufacture of the net gear is limited by expensive equipment, so the net gear manufacturing cost is higher
