Description
Technical Field
The invention belongs to the technical field of energy-saving and environment-friendly coatings, and relates to a high-temperature solar selective absorption coating and a preparation method thereof.
Background
Solar energy is a clean, renewable energy source. With the increase of the consumption of conventional energy, the storage capacity is gradually reduced, the greenhouse effect caused by the consumption of the conventional energy is increasingly serious, and the like, the development and utilization of new energy, clean energy and renewable energy are the direction of the national focus and promotion, wherein the solar energy is the first of the new energy due to the advantages of cleanness and inexhaustibility.
In the last 50 th century, the concept of solar selective absorption coatings was first proposed abroad, and a great deal of research was made on solar absorption coatings. The basic principle of the selective absorption coating is: the high absorptivity of the coating to the wave of the long wave band in the sunlight, and the low reflection and low transmissivity of the sunlight are utilized to realize the absorption of the sunlight energy with high ratio, and the sunlight energy is converted into heat energy and then converted into energy of other forms for utilization. Therefore, a solar selective absorbing coating with high absorptivity and low reflectivity is a research focus.
For the thin film type coating, the coating is usually prepared by adopting a chemical vapor deposition or physical vapor deposition method, although the performance is excellent, the process is complex, the requirement on the structure of the film layer is strict, the cost is high, and the coating is only suitable for various solar cells. For the coating of the paint, the paint is generally sprayed or brushed and dried to form, the preparation process is simple, the requirement on the structure of the film layer is low, and the cost is low. However, its performance is also relatively low.
In order to improve the performance of the solar energy absorption coating, the Shanghai traffic university proposes that a nickel alloy hollow sphere is used as an absorbent and is matched with high polymer resin to form a black nickel alloy hollow sphere-resin type composite coating, and the absorption rate of the coating is improved to 0.96. However, the coating has poor thermal stability and corrosion resistance, and is only suitable for low-temperature solar heat utilization.
Light-absorbing pigments, such as copper oxide, manganese oxide, chromium oxide, and the like, have excellent absorptivity to sunlight, have good high-temperature stability, and are commonly used for preparing high-temperature solar selective absorption coatings. But these materials have higher emissivity than black nickel. Moreover, in order to ensure excellent absorptivity of the coating, the addition ratio of the light-absorbing pigment is relatively high, which adversely affects adhesion stability, thermal shock resistance, bending resistance, and the like of the coating layer.
Therefore, the invention aims to provide a high-temperature solar selective absorption coating and a preparation method thereof.
