Method for preparing pollution-proof surface material suitably applied in marine environment

Abstract

The invention relates to a method for preparing a pollution-proof surface material suitably applied in the marine environment. The method comprises that: vinyl end capped dimethyl silicone polymer, hydrogen contained silicone oil, a platinum catalyst and polyacrylamide microcapsules are evenly mixed and stirred and sulfated at normal temperature to prepare the pollution-proof surface material of which hydrophilic surfaces and hydrophobic surfaces are distributed at intervals; the hydrophilic polyacrylamide microcapsules are evenly distributed on the material surfaces, and after the surface material is soaked in water, a local hydrophilic area with even distribution is formed, and the local hydrophilic area and the hydrophobic organic silicon surfaces are regularly distributed at intervals; polluted marine lives are not easy or not tight to be attached to the hydrophilic-hydrophobic surface, thereby preventing pollution; the pollution-proof surface material can strongly inhibit the attachment of marine lives such as diatom, mussels, and the like, and the attached quantity of mussel byssus is reduced by more than 50 percent; moreover, the surface material is environment friendly, nontoxic and unharmful.

Description

Technical field: [0001] The invention relates to a preparation method of an antifouling surface material suitable for marine environments, in particular to a preparation method of an amphiphilic antifouling material with a hydrophilic and hydrophobic surface interval distribution. The invention belongs to the technical field of protection against marine biological fouling. Background technique: [0002] There are a large number of marine organisms in seawater, and these marine organisms will adhere to the surfaces of ships and structures that have been in the seawater environment for a long time. This adhesion will increase the traveling resistance of the ship, seriously affect the sailing speed of the ship, increase fuel consumption, and at the same time damage the anti-corrosion coating on the surface of the ship and structures, thereby causing corrosion and damage on the surface of the hull and structures, seriously affecting its security. Therefore, it is very importan...

Problems solved by technology

Chinese patent CN1392208 discloses a preparation method of a bionic antifouling coating made of alkaloids extracted from marine algae and peptide compounds extracted from sponge organisms and fluorine-containing resins. Experiments and trials of the coating have shown that its It is very effective in preventing the attachment and parasitism of shellfish organisms, but it is greatly affected by the environmental conditions during use

[0005] In summary, in the prior art, antifouling coatings containing organotin and cuprous oxide are generally banned or restricted due to environmental pollution, while the existence of low surface energy silicone antifouling coatings is only effective for barnacles, etc. Good antifouling effect, less than ideal antifouling effect on diatoms, etc.
