specific Embodiment approach 1

[0010] Specific embodiment one: the preparation method of the superhydrophobic carbon fiber fabric boat in the present embodiment is as follows: one, by weight percentage by 0.1%~8% perfluoroalkyl siloxane, 1%~10% water, 1%~10% Acid, the rest is ethanol mixed solution composed of ultrasonic treatment for 30min ~ 120min, forming a perfluoroalkyl siloxane solution; 2. Immerse the carbon fiber fabric in the perfluoroalkyl siloxane solution for 10s ~ 60s, and then dry it; 3. Repeat step 2 for 2 to 5 times; 4. Dry the carbon fiber fabric treated in step 3 at 80°C to 150°C for 3h to 12h; 5. Wrap the carbon fiber fabric treated in step 4 outside the boat-shaped support to obtain super Hydrophobic carbon fiber fabric boat.

specific Embodiment approach 2

[0011] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the general chemical formula of perfluoroalkylsiloxane described in step 1 is CF 3 (CF 2 ) n Si(OC m h 2m+1 ) 3 , where n ranges from 2 to 200, and m ranges from 1 to 200. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0012] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the perfluoroalkylsiloxane chemical formula CF described in step one 3 (CF 2 ) n Si(OC m h 2m+1 ) 3 The value range of n is 3-18, and the value range of m is 1.5-2.5. Others are the same as in the first embodiment.

Abstract

The present invention relates to a preparation method of fabric boats and provides a preparation method for preparing an extra hydrophobic carbon fabric boat with the surface covered with a thin layer of poly perfluoro alkyl siloxane. The method comprises the steps of: immersing carbon fabric into perfluoro siloxane solution and air drying it; repeating the former processes for twice to five times; drying it and wrapping the surface of the boat support body by processed carbon fabric. The invention realizes hydrophobicity of carbon fabric surface by coating hydrophobic substance (perfluoro alkyl siloxane) on the macroscopic and rough surface of carbon fabric itself. The carbon fiber fabric boat achieves the characteristics of light mass, small underwater driving resistance, large stealth carrying capacity and good corrosion resistance.

Description

technical field [0001] The invention relates to a method for preparing a fiber fabric boat. Background technique [0002] Carbon fiber is an inorganic polymer fiber with a carbon content higher than 90%. Among them, those with a carbon content higher than 99% are called graphite fibers. As the name suggests, it not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. Compared with traditional glass fiber (GF), the Young's modulus is more than 3 times; compared with Kevlar fiber (KF-49), not only the Young's modulus is about 2 times, but also in organic solvents Insoluble and non-swelling in acid and alkali, with outstanding corrosion resistance. Some scholars soaked PAN-based CF in a strong alkali NaOH solution in 1981. It has been more than 20 years, and it still maintains the fiber form. Its specific gravity is less than 1 / 4 of that of steel. Th...
