Abstract

The invention describes a low solar absorbing energy-saving type neutral gray hull finish coat, including polyhydroxy component and polyisocyanate component, wherein, the polyhydroxy component includes 40-60% of the hydroxyl acrylic resin; 23-43% of reflecting layer color stuffing composed of a mixture black pigment of rutile type titanic dioxide, steel solid ceramic micro-beads, iron oxide and nickel oxide and blue pigment formed by high-temperature calcinations of cobalt oxide and alumina; 5% of the mixed solvents; as well as 0.5-1.0% of disperser, 0.3-1.0% of anti-foaming agent, 0.5-1.5% of thixotropic agent and film-forming additive. The inventive coating, as a surface layer, can improve the coating reflection index and radiation rate to realize the cooling effect and heat-insulating effect; can reduce indoor temperature improvement caused by solar radiation, which can be sued in the top and outer wall of the ship superstructure to reduce the cabin temperature and save the coolingcosts.

Description

Technical field [0001] The invention relates to a technology in the field of special functional materials, in particular to a low solar absorption energy-saving mid-gray ship hull finish paint. Background technique [0002] With the rapid development of the global construction industry, petroleum industry, transportation industry, and ordnance industry, people at home and abroad are paying more and more attention to environmental protection cooling and improving production safety. At present, the research of various cooling coatings abroad is very active and has been widely used in many fields. For example, the US Shield energy-saving coatings are used in space shuttle thermal insulation, and hollow ceramic beads are used as fillers. This type of coating can make the coated object such as a house. The internal temperature is greatly reduced, air-conditioning costs are significantly reduced, and energy saving is about 40%. At the same time, it has good anti-corrosion, flame-retard...
