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.
