Abstract
A solar heat absorbing paint is prepared by mixing a nano magnetic powder, a variety of nano metal powders, a ceramic powder, epoxy resin and a variety of additives. The paint provided by the invention is prepared by evenly mixing and stirring the components in the formula at room temperature. The production process is simple, convenient, economical and environment-friendly. The paint provided by the invention can be used individually; and a coating of the paint has high absorption rate, high thermal conductivity, low radiation, high temperature resistance, high stability, strong adhesion, compactness and stability. The paint is ideal for solar energy absorption, can be widely used as the heat absorbing coating for solar collector, and absolutely can substitute the existing expensive solar energy absorption coating.
Description
Technical field
