Abstract

The invention discloses a multifunctional marine coating. The multifunctional marine coating comprises the following raw materials in parts by weight: 15-30 parts of polyamide resin, 5-15 parts of flaky aggregate, 3-10 parts of biological antifouling agent, 2-10 parts of antirust pigments, 1-5 parts of flash-rust inhibitor, 20-35 parts of nanoscale filler and 5-15 parts of additive. The multifunctional marine coating is distributed on the surface of a material in a flaky manner, and multiple layers of flakes are arranged in a horizontal overlapping manner, so that the path of a corrosive medium penetrating into a base material is prolonged, and the anticorrosion property of the coating is improved; as the multifunctional marine coating contains the natural biological antifouling agent, the multifunctional marine coating has very strong avoidance and blunting effects on marine organisms, is capable of stopping the adhesion of the marine organisms but has no toxic effect on the marine organisms; the antirust pigment is capable of preventing equipment from rusting and facilitates the improvement of dry adhesive force of the coating; the antirust pigment is matched with the flash-rust inhibitor to obtain a very good flash-rust inhibition effect.

Description

technical field [0001] The invention relates to a coating, in particular to a multifunctional marine coating, which has the functions of preventing biological adhesion, seawater corrosion and rust, and belongs to the technical field of coatings. Background technique [0002] Seawater is the largest and highly corrosive natural electrolyte in nature. Seawater contains almost all chemical elements on the earth, and its composition is very complex. In addition, seawater also contains dissolved oxygen, marine life and decaying organic matter. These substances have caused great harm to metal components such as various marine transportation tools, oil production platforms, and marine equipment. With the development of coastal transportation, industrial production, and national defense construction in various countries, the threat of seawater and marine atmospheric corrosion has also become more and more serious. more prominent. [0003] In addition, the attachment of marine orga...
