Problems solved by technology

[0005] At present, the strapping used for foreign buoyancy materials is mainly a ring-shaped strapping of resin composite fiber. The key point is the uniformity of joints and fiber distribution. In the secret technology of major foreign companies, it is a huge challenge to solve the problems of material selection and molding process for strapping

Embodiment 1

[0050] Take 100 parts of EPDM rubber (ethylidene norbornene is the third monomer), 40 parts of carbon black, 1 part of polyene-based radiation sensitizer TAIC, 0.5 part of antioxidant 1010, and plasticizer Hexadiene 0.5 parts of didecyl acid, 0.5 parts of zinc stearate as a stabilizer, and 0.5 parts of a surface treatment agent were placed in a high-speed mixer and stirred at a high speed for 5 minutes, 500 rpm, and the material did not exceed 60 °C. Take out the material and put it into a twin-screw extruder to extrude into a figure 1 Shown is EPDM 1 with grooved structure and a smooth belt without grooved structure. The carbon fiber is wound on a large heatable circular roller 200 of EPDM 1 with a grooved structure, and then attached with a smooth rubber band. Wherein the groove spacing is 1 mm, the rubber belt width is 5 cm, and the ring rubber belt diameter is 1.2 meters. Afterwards, the big roller is heated to 140°C, and the small roller 300 extrudes the three-layer str...

Embodiment 2

[0052] Take 100 parts of EPDM rubber (1,4-hexadiene is the third monomer), 50 parts of carbon black, 1.5 parts of polyene-based radiation sensitizer TMPTMA, 0.5 part of antioxidant 1010, plasticizer Put 0.5 part of didecyl adipate, 0.5 part of zinc stearate as a stabilizer, and 0.5 part of surface treatment agent into a high-speed mixer and stir for 5 minutes at a high speed, 500 rpm, and the material does not exceed 60 °C. Take out the material and put it into a twin-screw extruder to extrude into a figure 1Shown is EPDM 1 with grooved structure and a smooth belt without grooved structure. The glass fiber is wound on a large roller 200 of EPDM 1 with a grooved structure, and then a smooth rubber band is attached. Wherein the pitch of the grooves is 2mm, the width of the rubber belt is 5cm, and the diameter of the annular rubber belt is 1.2 meters. Afterwards, the large roller 200 is heated to 140°C, and the small roller 300 extrudes the three-layer structure of the strappin...

Abstract

The invention discloses a strapping tape for a deep sea buoyancy material and a preparation method thereof. The strapping tape material takes ethylene propylene diene monomer rubber as a matrix resin, graphite powder as a reinforcing agent, gamma-chlorine propyl triethoxy silane as a surfactant, multi-alkenyl irradiation sensitizing agent as a cross-linking auxiliary, quad[beta-(3,5-ditertiary butyl-4-hydroxide phenyl) propionic acid] pentaerythritol ester-1010 as an antioxidant, diisodecyl adipate-DDA as a plasticizing agent, zinc stearate-ZnSt2 as a stabilizing agent. A final annular strapping tape product can be obtained by proportioning the components according to a certain ratio, extruding to form an ethylene propylene diene monomer rubber strip and a smooth rubber strip of groove structures by using a double-screw rod extruder, annually winding high-performance fibers on a large rolling shaft with the ethylene propylene diene monomer rubber strip of the groove structure, subsequently attaching the smooth rubber strip, and subsequently forming in a mutual extrusion manner by using the large rolling shaft and the small rolling shaft which can be heated, after extrusion forming, taking down the extruded strapping tape from the large rolling shaft, and subsequently performing normal temperature irradiation cross-linking aftertreatment in a high-energy electronic accelerator.

Description

technical field [0001] The invention relates to a strapping and a preparation method thereof, in particular to a strapping for deep-sea buoyancy materials and a preparation method thereof, belonging to the marine equipment industry. Background technique [0002] Strapping straps for deep-sea buoyancy materials refer to the indispensable equipment materials used to tie buoyancy materials in ocean development. At present, the common strapping straps in China are mostly steel strapping straps and plastic strapping straps (such as nylon, polypropylene, polyester, etc.), which are mostly used in the field of cargo strapping and packaging. [0003] Although steel strapping has high tensile strength, it has poor corrosion resistance; nylon strapping has high continuous tension, but its elongation and recovery rate are larger than polyester or polypropylene, and its dimensional stability is poor; polypropylene strapping is generally Used for bundling, bundling and sealing cartons w...
