In order to get coatings with low glossiness, bright and polychrome, especially with the property of low infrared emissivity, a novel method for doping the nano pigment is proposed. The influence of the content of nano pigment on emissivity, color and lightness is investigated, moreover the mechanical property and the neuter salt spray resistance property of the coating are studied. The experimental results show that the infrared emissivity in 8—14 μｍ is around 0.3, and the lightness and the glossiness are both decreased with the pigment content increasing. When the content is increased to 25%, the lightness and the glossiness (60°) of the coating are reduced to 28.8%, 54.5%, respectively. And, the coating has the relatively excellent mechanical and anti-corrosion properties.
