Problems solved by technology

[0004] At present, it is generally used in the market to spray black organic coatings on the heat-absorbing plate core of solar collectors, such as black fluorocarbon resin, black epoxy resin, black polyurethane resin, etc., because ordinary resin materials are used as adhesives. 2. Since ordinary carbon black or black pigments are used as the color body, there is no spectrum selectivity
Therefore, its coating has a high emissivity, which results in low thermal efficiency of the solar collector.

Abstract

The invention discloses a solar panel selective heat absorption material and a preparation method thereof. The solar panel selective heat absorption material is prepared from the following raw materials in parts by mass: 5-10 parts of a nano-scale spinel type pigment, 4-8 parts of nickel powder, 30-50 parts of linseed oil based waterborne polyurethane-polyacrylic resin, 8-12 parts of drying oil alkyd resin, 4-8 parts of anhydrous acetone, 4-8 parts of EFKA3570, 4-12 parts of SN-5027 and 8-20 parts of a polyether modified silicone oil defoamer. The solar panel selective heat absorption materialprovided by the invention is simple in preparation technology, low in cost and liable in industrial production; and in addition, a coating prepared by using the material is high in heat absorption rate and low in light emitting rate and has good mechanical properties and stronger weatherability.

Description

technical field [0001] The invention relates to the technical field of solar heat absorption, in particular to a selective heat absorption material for a solar panel and a preparation method thereof. Background technique [0002] Energy utilization plays a pivotal role in the development of human society, but the excessive development of resources and inefficient resource utilization make human beings face a severe test. As we all know, solar energy is the most abundant and widely available renewable energy, which plays a major role in solving energy crisis and environmental problems. , making it a hot research topic in various countries. [0003] Solar absorbing coatings are mainly divided into spectrally selective absorbing coatings and high-absorbing absorbing coatings. Spectrum-selective heat-absorbing coatings are special coatings with high absorption of visible-near-infrared light and high reflection of infrared light. , that is, it can effectively absorb solar energ...
