Abstract

The invention discloses an epoxy anticorrosive antibacterial paint which is composed of 30-40% of bisphenol A epoxy resin, 8-15% of phenol formaldehyde amine, 5-10% of antimicrobial modified resin and nano silicon solution in a weight ratio of 30:1, 5-10% of polyurethane, 10-18% of butadiene-acrylonitrile rubber, 10-17% of flaky high-wear-resistance pigment and filler, 0.5-0.9% of dispersing agent, 0.4-0.8% of defoaming agent, 0.4-0.8% of preservative, 0.2-0.5% of leveling agent and 15-23% of deionized water. The epoxy anticorrosive antibacterial paint has the advantages of favorable corrosion resistance, favorable impact resistance, favorable toughness and favorable mold resistance.

Description

technical field [0001] The invention relates to an epoxy anticorrosion and antibacterial coating. 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 coating to flake off and fail. In addition, for the coating layer in special occasi...
