Embodiment 1
[0017] 1. Wash the shark skin with 1%-5% glutaraldehyde and soak it for more than 20 hours;
[0018] 2. Do 5 dehydration treatments with absolute ethanol, 20-60 minutes each time;
[0019] 3. Dry in an oven at 80°C for 4-6 hours;
[0020] 4. After the dried shark skin, apply a layer of 1-2 cm polymer forming repair material, and cure at room temperature for 24 hours;
[0021] 5. Mix liquid silicone and vulcanizing agent at a ratio of 100:0.5, and place it in the mold;
[0022] 6. Put the shark skin on the silicone rubber, apply a pressure of 5MPa-2MPa to flatten it, put it in 80℃~240℃ for 1-3 minutes to vulcanize
[0023] 7. Remove the silicone rubber to obtain a silicone rubber mold with a shark scale shell microstructure surface.
Embodiment 2
[0025] 1. Wash the shark skin with 3% glutaraldehyde and soak it for 20 hours;
[0026] 2. Do 5 dehydration treatments with absolute ethanol, 40 minutes each time;
[0027] 3. Dry in an oven at 80°C for 6 hours;
[0028] 4. After the dried shark skin, apply a layer of 2cm Belzona repair material and cure at room temperature for 24 hours;
[0029] 5. Mix Dow Corning No. 184 liquid silicone and vulcanizing agent at a ratio of 100:0.5, and place it in the mold;
[0030] 6. Put the shark skin on the silicone rubber, apply a pressure of 2 MPa to flatten it, and put it in 150°C for 3 minutes to vulcanize;
[0031] 7. Remove the silicone rubber to obtain a silicone rubber mold with a shark scale shell microstructure surface.

Abstract
The invention provides a preparation method for replicating a shark skin surface micro-structure. The method is to take a shark skin which is cleaned and chemically treated as a template and obtain a silicone rubber membrane with a shark skin placoid scale micro-structure surface through silicone rubber hot pressing. The method comprises the following steps: 1, cleaning the shark skin; 2, dehydrating the shark skin; 3, flattening the shark skin; 4, drying the shark skin; 5, curing and repairing the shark skin; 6, mixing silicone rubber with a vulcanizing agent and vulcanizing the mixture; 7, placing the shark skin in a mold and injecting the silicone rubber into the mold; 8, placing the mold in a thermal pressure forming machine for curing; and 9, carrying out the demolding the shark skin to obtain the membrane with the shark skin placoid scale micro-structure surface. The products with the shark skin groove placoid scale structure which is replicated by a biological pouring membrane method can be widely applied in the industries such as shipping, and the like.
Description
Technical field: [0001] The invention relates to a preparation method of a product in the field of bionics that replicates the surface of a biological groove scute scale structure with anti-algae and drag reduction, in particular a preparation method for replicating the microstructure of the surface of shark skin. Background technique [0002] At present, chemical agents such as air flotation and chlorine used in drinking water to kill algae have problems such as algae's tolerance to drugs; power consumption and complicated process. Drug pollution does not meet the requirements of environmental protection and energy saving, and its use has been expressly prohibited. [0003] The anti-algae paint used in the shipping industry has been banned worldwide due to lead, copper, and pesticides. However, rattan gourds and other marine organisms attach to the bottom of the ship, causing fouling and corrosion on the surface of the hull, increasing drag resistance during navigation, an...
