Problems solved by technology

The existing amount of nylon 66 fishing net line is relatively large, and long-term production, processing and use will produce a large amount of waste, and these wastes are mostly disposed of by incineration and landfill, which is not conducive to environmental safety and wastes raw materials.
People try to reprocess these waste materials, but due to the poor recycling process, the overall quality of the regenerated fishing net line cannot meet the requirements, and further improvement is needed

Embodiment 1

[0026] Low-cost production process of twine good flame retardancy, comprising the steps of:

[0027] (1) Extraction of waste material:

[0028] . A The scrap nylon twine 66 into the sulfuric acid solution, and then acetic anhydride was added, sonicated well and then stirred, followed by cooling and crystallization, and finally filtered to obtain filtrate A standby;

[0029] . B was added to the filtrate obtained operating a barium sulfate A, mix well before addition of calcium hydroxide and nanofiller, the reaction process after 3h was filtered to obtain the filtrate B backup;

[0030] . C operation b B obtained filtrate by distillation under reduced pressure, to give waste material after the completion of use;

[0031] (2) Nylon 66 wet resin prepared:

[0032] a. The step (1) of waste material obtained with adipic acid, blended with an ethanol solution, after neutralization and a salt precipitated was then filtered, washed alcohol, after the drying process, is configured to 50% m...

Embodiment 2

[0045] Low-cost production process of twine good flame retardancy, comprising the steps of:

[0046] (1) Extraction of waste material:

[0047] . A The scrap nylon twine 66 into the sulfuric acid solution, and then acetic anhydride was added, sonicated well and then stirred, followed by cooling and crystallization, and finally filtered to obtain filtrate A standby;

[0048] . B was added to the filtrate obtained operating a barium sulfate A, mix well before addition of calcium hydroxide and nanofiller, treatment 3.3h the reaction was filtered to obtain the filtrate B backup;

[0049] . C operation b B obtained filtrate by distillation under reduced pressure, to give waste material after the completion of use;

[0050] (2) Nylon 66 wet resin prepared:

[0051] a. The step (1) of waste material obtained with adipic acid, blended with an ethanol solution, after neutralization and a salt precipitated was then filtered, washed alcohol, after the drying process, is configured to 56% of ...

Embodiment 3

[0064] Low-cost production process of twine good flame retardancy, comprising the steps of:

[0065] (1) Extraction of waste material:

[0066] . A The scrap nylon twine 66 into the sulfuric acid solution, and then acetic anhydride was added, sonicated well and then stirred, followed by cooling and crystallization, and finally filtered to obtain filtrate A standby;

[0067] . B was added to the filtrate obtained operating a barium sulfate A, mix well before addition of calcium hydroxide and nanofiller, the reaction process after 3.5h was filtered to obtain the filtrate B backup;

[0068] . C operation b B obtained filtrate by distillation under reduced pressure, to give waste material after the completion of use;

[0069] (2) Nylon 66 wet resin prepared:

[0070] a. The step (1) of waste material obtained with adipic acid, blended with an ethanol solution, after neutralization and a salt precipitated was then filtered, washed alcohol, after the drying process, is configured to 60%...

Abstract

The invention discloses a manufacturing process of a fishing net thread with low cost and good flame retardance, which belongs to the technical field of fishing net thread manufacturing, and comprisesthe steps of (1) waste material extraction, (2) nylon 66 wet resin preparation, and (3) finished fishing net thread manufacturing. The invention provides a fishing net thread manufacturing process which is low in overall cost and beneficial to application and popularization. The fishing net thread prepared through the manufacturing process has the characteristics of being good in temperature resistance and flame retardance and high in strength and weather resistance.

Description

Technical field [0001] The present invention belongs to the technical field of manufacturing fishing nets, particularly relates to a low-cost flame retardant twine good production process. Background technique [0002] Since my country fishnet material since the early sixties and gradually try synthetic material, after decades of application, basically instead of the original cotton material, fishnet material from the current domestic and international use of the situation, there are sub-species of polyamide (PA ), polyester (PES), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyvinyl alcohol (PVA), polyvinylidene chloride (PVD) seven categories of points from the fiber form : there monofilament, multifilament, split fibers, etc., its varieties and specifications are more complete, the fiber strength index compared with similar foreign products, are relatively close. The existing amount of nylon fishing nets line 66 is larger, long-term production, processing...
