Problems solved by technology

With the passage of time, the attached algae or shells and other organisms will gradually increase. On the one hand, it will cause an extra burden on the rope. On the other hand, it will also cause corrosion to the rope, greatly reducing the service life of the rope. To a certain extent, it will affect the safety of marine operations

Embodiment 1

[0027] Such as Figure 1-4 As shown, a kind of anti-fouling rope includes a cable body 6, which is braided by several strands, and the outer wall of each strand 3 is sequentially provided with a nano antifouling layer and an organic Silicone anti-adhesion layer2. The nano-anti-fouling layer is set as a nano-polyethylene layer or a nano-polyurethane layer. In this embodiment, the nano-anti-fouling layer is set as a nano-polyethylene layer 1 . The thickness of the nano polyethylene layer 1 is set to 0.5 mm, and the thickness of the organosiloxane anti-adhesion layer 2 is 1 mm. The core portion of the cable body 6 is provided with a bubble generating tube 4 , and the length of the bubble generating tube 4 is greater than that of the cable body 6 . Specifically, the top of the bubble generating tube 4 protrudes from the cable body 6 for easy connection with the fan 7 . Several bubble holes 5 are arranged on the outer wall of the bubble generating tube 4, and the diameter of the...

Embodiment 2

[0029] On the basis of Example 1, different from Example 1, the outer wall of the nano-antifouling layer is also coated with a bactericidal anti-adhesion layer. The bactericidal anti-adhesion layer includes the following components in parts by weight: 10 parts of bisphenol A epoxy resin, 10 parts of magnesium oxide, 3 parts of sodium dodecylbenzenesulfonate, 2 parts of zinc oxide, and 5 parts of formaldehyde solution , 9 parts of nano silicon dioxide.

[0030] The preparation method of above-mentioned bactericidal anti-adhesion layer is:

[0031] (1) Add bisphenol A type epoxy resin to methanol solution, place it in an ultrasonic device, ultrasonicate at 70°C for 30 minutes, and dissolve it for later use;

[0032] (2) After step (1) is completed, add sodium dodecylbenzenesulfonate, emulsify and disperse for 20 minutes under mechanical stirring at 1600r / min, and obtain an emulsion for later use;

[0033] (3) Adjust the pH of the emulsion obtained in step (2) to 8, then add ma...

Embodiment 3

[0035] On the basis of Example 1, different from Example 1, the outer wall of the nano-antifouling layer is also coated with a bactericidal anti-adhesion layer. The bactericidal anti-adhesion layer includes the following components in parts by weight: 13.8 parts of bisphenol A epoxy resin, 6.2 parts of magnesium oxide, 3 parts of sodium dodecylbenzenesulfonate, 2.2 parts of zinc oxide, and 6 parts of formaldehyde solution , 9 parts of nano silicon dioxide.

[0036] The preparation method is the same as in Example 2.

Abstract

The invention relates to a rope, in particular to an anti-biological-attachment rope. The rope comprises a rope body, the rope body is woven from multiple strands of ropes, and a nano anti-dirt layerand an organic siloxane anti-attachment layer are arranged on the outer side wall of each strand of rope from outside to inside in sequence; a rope core part of the rope body is provided with a bubblegeneration pipe, multiple bubble holes are formed in the outer side wall of the bubble generation pipe, and a gas generation device is connected to the top of the bubble generation pipe. According tothe anti-biological-attachment rope, by arranging the nano anti-dirt layers and the organic siloxane anti-attachment layers, biological-attachment is effectively prevented. For the bubble generationpipe arranged on the rope core part, through a fan, air enters the bubble generation pipe and is further discharged through the bubble holes, multiple circulation bubbles are generated on the periphery of the rope, and biological-attachment is further interfered through the generated bubbles. The anti-biological-attachment rope is simple in overall structure and suitable for application and popularization and has an obvious anti-biological-attachment effect.

Description

technical field [0001] The invention relates to a rope, in particular to a biological adhesion prevention rope. Background technique [0002] Ropes are often used in marine operations. During the use of the ropes, when the ropes need to be placed in seawater for a long time, algae or shellfish are easy to adhere to the ropes. With the passage of time, the attached algae or shells and other organisms will gradually increase. On the one hand, it will cause an extra burden on the rope. On the other hand, it will also cause corrosion to the rope, greatly reducing the service life of the rope. To a certain extent, it will affect the safety of marine operations. Therefore, how to develop a kind of anti-fouling rope has important practical significance. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the invention provides an anti-biological adhesion cable. [0004] Technical scheme of the present invention is: [0005] An anti-biologic...
