Abstract

The invention belongs to the field of coatings and particularly relates to an antibacterial epoxy coating for anchor chains and a preparation method thereof. The antibacterial epoxy coating for anchorchains comprises, by weight, 30-50 parts of bisphenol A epoxy resin, 10-15 parts of phenalkamines, 10-15 parts of diatom ooze, 8-12 parts of polyurethane, 7-8 parts of nitrile butadiene rubber, 8-9 parts of a high-wear-resistance pigment filler, 5-8 parts of polyethylene wax emulsion, 8-12 parts of modified silica, 1-2 parts of a dispersant, 1-2 parts of a defoaming agent, 3-5 parts of a levelingagent, 2-3 parts of a film-forming aid, 2-3 parts of an anti-freezing agent, and 10-15 parts of deionized water. The antibacterial epoxy coating for anchor chains prepared herein has good corrosion resistance, impact resistance, toughness, antibacterial property and dispersibility.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an antibacterial epoxy coating for anchor chains and a preparation method thereof. Background technique [0002] There are three main functions of anti-corrosion coatings: the shielding effect of paint film and sheet pigment, the corrosion inhibition and passivation effect of alkaline or oxidative pigments, and the electrochemical protection effect of zinc powder. Among them, the shielding effect that can isolate corrosive media such as water, oxygen, and ions is the most critical. At present, most of the commonly used marine heavy-duty anti-corrosion coatings are solvent-based coatings. During the film formation process, the pinholes left by the solvent volatilization will cause the corrosive medium to penetrate under the film and cause corrosion. The resulting corrosion product expands and breaks the coating, allowing the corrosive medium to diffuse, eventually causing the...
