Preparation method of graphene and capsaicin synthetic ship bottom paint

Abstract

The invention discloses a method for preparing a graphene capsaicin synthetic boat bottom paint. The components include: 10-12 parts of graphene, 10-16 parts of capsaicin, 20-23 parts of acrylic resin, and 5-6 parts of chlorinated paraffin 6-8 parts of xylene, 20-28 parts of talcum powder, 13-15 parts of zinc yellow, 3-5 parts of additives; among them, graphene has high strength, wear resistance, self-lubrication and excellent conductivity characteristics, can greatly increase the wear resistance of ship bottom paint; capsaicin is a stable alkaloid; it is not affected by temperature, and has the function of antibacterial and repelling marine attached organisms; compared with chemical coating additives, spicy It will not poison attached organisms, cause biological variation, and will not destroy the marine food chain or cause sea water pollution; and it has good matching properties when mixed with acrylic resin, chlorinated paraffin, xylene, talcum powder, and zinc yellow. Good adhesion and compatibility.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a method for preparing a graphene capsaicin-synthesized boat bottom paint. Background technique [0002] Marine biofouling is the biofouling formed by the adsorption and growth of marine microorganisms, animals and plants on the surface of the hull or marine facilities, which brings many adverse effects to marine shipping and development. Marine biofouling will increase the navigation resistance of ships, lead to accelerated metal corrosion, block seawater pipelines, and reduce the service life of marine equipment. For this reason, people have studied a variety of antifouling technologies. In the early days, compounds such as mercury and arsenic were used to prepare antifouling coatings, but they were eliminated due to the high toxicity of these substances; Antifouling paints formulated with vinyl resin and chlorinated rubber as the main base materials; since the 1960s, people ...

Marine biofouling will increase the navigation resistance of ships, lead to accelerated metal corrosion, block seawater pipelines, and reduce the service life of marine equipment

For this reason, people have studied a variety of antifouling technologies. In the early days, compounds such as mercury and arsenic were used to prepare antifouling coatings, but they were eliminated due to the high toxicity of these substances; Antifouling paints formulated with vinyl resin and chlorinated rubber as the main base materials; since the 1960s, people have applied organotin compounds to antifouling paints to prolong the antifouling time, but these antifouling paints contain chemical toxicity Substances have the defect of polluting the marine environment, and the traditional antifouling paint is poor in seawater impact resistance, and the wear resistance is generally about 1 year; it needs frequent paint repairs and maintenance, which leads to increased maintenance costs for the hull, which affects the antifouling and antifouling properties of the hull. Rust has brought many disadvantages
