Abstract

The invention provides a waterborne epoxy resin cabin coating. The coating comprises a component A and a component B in a weight ratio of (8-5): 1. The component A comprises the following components in percentage by mass: 30%-50% of an epoxy resin emulsion, 7%-15% of an antirust pigment, 20%-50% of a pigment filler, 1%-2% of a coalescing agent, 5%-8% of other auxiliaries and 5%-30% of water. The component B is a water-based epoxy amine curing agent with a solid content of 45-55% and with a solvent being water. According to the waterborne epoxy resin cabin coating, the VOC content of a cured paint film meets the environmental protection standard that the VOC content is smaller than or equal to 80 g / L, the adhesive force between the paint film and a substrate is larger than or equal to 5 MPa, the water contact angle of the paint film reaches 100 degrees or above and is kept stable, and recoating is easy; and the waterborne epoxy resin cabin coating has excellent salt spray resistance andcorrosion resistance.

Description

Technical field [0001] The invention relates to the field of ship coatings, and mainly relates to a water-based epoxy resin engine room coating and a preparation method thereof. Background technique [0002] At present, the paints used on ships are all oil-based paints, which will produce a large amount of volatile organic compounds (VOC) during the construction process, which not only pollutes the environment, but also prone to accidents such as fire and poisoning; in the application process, especially the soft coating of the insulating layer During construction, the soft covering cloth and insulating materials are porous materials, which absorb a large amount of paint, and it is easy to seal the organic solvent inside the porous substrate, which affects the health of the working and living personnel in the cabin. [0003] Water-based paint uses water as the dispersion medium, which can save a lot of petroleum resources, reduce VOC emissions, and reduce environmental pollution. I...
