High-solid thick film anti-corrosion, antifouling and environment-friendly coating for marine equipment

Abstract

The invention discloses a high-solid thick film anti-corrosion, antifouling and environment-friendly coating for marine equipment. The coating is prepared from components in parts by weight as follows: 15-60 parts of self-polishing type polymer resin, 15-60 parts of a biological antifouling agent, 10-30 parts of pigment and filler, 1-10 parts of an aid, 10-30 parts of a solvent, 15-60 parts of rosin, 6-10 parts of a dispersant, 20-30 parts of Rutgers L300 small-molecular petroleum resin, 10-20 parts of graphene and 2-5 parts of nano fluorine ions, wherein the self-polishing type polymer resincomprises, in parts by weight, 15-75 parts of a tri-organosilicon-based vinyl unsaturated monomer, 2-10 parts of an acrylate monomer and 5-80 parts of an acrylic acid type vinyl unsaturated monomer. Environment-friendly biotoxin is introduced and dissolved in the coating through the dispersant, the interpenetrating network effect is formed under a micro-phase separation effect in a crosslinking reaction process on the premise that the crosslinking density is not reduced and the coating hardness is guaranteed, so that energy can be dissipated among numerous micro-phase interfaces, and environment-friendly toxin is slowly released through self-polishing of the coating and causes lower environmental pollution.

Description

technical field [0001] The invention relates to the technical field of environment-friendly coatings, in particular to a high-solid-thick-film corrosion-resistant, anti-pollution, and environment-friendly coating for marine equipment. Background technique [0002] Due to the diversity of marine life and the complexity of the marine environment, when marine biofouling occurs, marine microorganisms, animals and plants will adsorb and grow on the surface of the ship's water body and marine facilities to form biofouling, which has many adverse effects on marine transportation and development. Marine antifouling has become a worldwide problem. Although organotin biocidal materials are effective antifouling materials, the use of this material has been banned by the International Maritime Organization (IMO) due to damage to marine ecology. Currently, international brands such as Jotun, The long-term antifouling coatings developed and produced by foreign companies such as Kansai, BA...
