Embodiment 3

[0047] Embodiment 3: The main braided net after stretching is used on the aquaculture net. The cross-section profile of the aquaculture net is circular, with a diameter of 1 to 30 mm. It consists of three main braided ropes 1 and six secondary braided ropes 2. It is braided in a spiral shape, with two secondary braided ropes wrapped around each main braided rope.

[0048] Each secondary braided rope includes two nylon threads 21 and eight fiber filaments 22, and the fiber filaments are wound on the nylon threads.

[0049] The two secondary braided ropes wound on the main braided rope are wound in a knot every 20 centimeters, and put on the rubber sheath 3.

[0050]The diameter of the nylon thread in each secondary braided rope is 0.35mm-0.8mm, and the diameter of the fiber filament is 0.25mm-0.3mm.

Abstract

The invention discloses a flexibilizer in breeding net main braid rope stretching preparation. The flexibilizer is prepared from 30 to 50 parts of an acrylate polymer, 50 to 70 parts of an acrylate-grafted styrene elastomer, 10 to 30 parts of an antioxidant, 25 to 100 parts of para-aminobenzoic acid, 4 to 16 parts of sodium hydroxide, 250 to 260 parts of water, 10 to 12 parts of zinc oxide, 6 to 9parts of a surfactant, 3 to 6 parts of sodium metasilicate, 1 to 2 parts of sodium carbonate, 10 to 12 parts of ammonium hydroxide, 16 to 24 parts of corn oil, 5 to 8 parts of a thermoplastic polyolefin elastomer graft, 4 to 5 parts of polyolefin and 1 to 10 parts of nylon. Through use of a small amount of nylon and grafting of the nylon to the nylon flexibilizer, the nylon flexibilizer has toughening characteristics and compatilizer characteristics. The flexibilizer can greatly improve mixing effects on the flexibilizer and nylon, improve the sea island-type toughened nylon structure, reducethe microstructure defects of the sea island-type toughened nylon and further improve the mechanical property of the toughened nylon.

Description

Technical field: [0001] The invention relates to a product for fish, in particular to a toughening agent added in the stretching preparation process of the main braided rope of the breeding net. Background technique: [0002] Breeding nets, more than 99% are made of synthetic fibers, mainly monofilament, multifilament or multi-single filament of nylon 6 or modified nylon, polyethylene, polyester, polyvinylidene chloride and other fibers can also be used, usually used The Raschel warp knitting machine equipped with 4 to 8 bars connects the warp yarns into loops and connects them into a net, which is called warp knitting knotless net. Due to the high speed of the warp knitting machine (600 rpm), the knitted net has a wide width, and the number of cross-mesh can reach more than 800 mesh. It is convenient to change the specifications, and the production efficiency is several times higher than the previous two methods. The warp-knitted knotless net is flat, light in weight, stab...
