Low-solar absorption energy-saving weather-resistant ocean grey finish paint and preparation method thereof

Abstract

The invention discloses low-solar absorption energy-saving weather-resistant ocean grey finish paint which consists of a component A and a component B, wherein the component A comprises the following components in percentage by mass: 35-45 percent of polyurethane resin, 25-35 percent of modified titanium dioxide, 5-15 percent of kaolin or calcium carbonate, 0.5-1.5 percent of functional black pigment, 0.1-0.3 percent of functional green pigment, 8-18 percent of solvent and 2-5 percent of aids; the component B comprises the following component in percentage by mass: 10-15 percent of aliphatic polyisocyanate. The low-solar absorption energy-saving weather-resistant ocean grey finish paint is applied to hulls above ship waterlines and outer surfaces of superstructures, adsorption of outer walls of the ships on sunlight illumination energy can be reduced, increase of temperature in the compartment is reduced, the living and working conditions of the crew are improved, and lots of cooling cost is saved.

Description

technical field [0001] The invention belongs to the field of special functional materials, and in particular relates to a low-solar-absorbing, energy-saving and weather-resistant sea-gray finish paint. Background technique [0002] With the rapid development of the global construction industry, petroleum industry, transportation industry, weapon industry, etc., environmental protection and cooling, and improving production safety have attracted more and more attention from people at home and abroad. At present, the research on various cooling coatings abroad is very active and has been widely used in many fields. For example, the United States has developed a coating for thermal insulation of space shuttles. It uses hollow ceramic microbeads as fillers. This type of coating can make the coated object (such as a house) the internal temperature is greatly reduced, and the air conditioning fee is significantly reduced (energy saving is about 40%). At the same time, it has good ...
