NOVELTY - A solar-heat-absorbing coating is prepared using a resin, an absorbent, an additive, and a solvent. The resin is acrylic resin. The absorbent comprises carbon black and chromium oxide green. The additive comprises dispersant, leveling agent, plasticizer, coupling agent, and anti-settling agent. The dispersing agent is polymer type dispersant. The leveling agent is silicone oil liquid. The plasticizer is dibutyl phthalate. The coupling agent is silane coupling agent. The anti-settling agent is organic bentonite.    USE - Solar-heat-absorbing coating (claimed).    ADVANTAGE - The solar-heat-absorbing coating has dual color and excellent weather resistance, and efficiently converts solar energy into heat energy.    DETAILED DESCRIPTION - A solar-heat-absorbing coating is prepared using a resin, an absorbent, an additive, and a solvent. The resin is acrylic resin. The absorbent comprises carbon black and chromium oxide green. The additive comprises dispersant, leveling agent, plasticizer, coupling agent, and anti-settling agent. The dispersing agent is polymer type dispersant. The leveling agent is silicone oil liquid. The plasticizer is dibutyl phthalate. The coupling agent is silane coupling agent. The anti-settling agent is organic bentonite. The solvent comprises acetone, butyl acetate, and xylene. The coating comprises 28-35 pts. wt. 48-53% acrylic resin, 1-2.4 pts. wt. carbon black, 4-9 pts. wt. black enamel, 1.1-1.8 pts. wt. chromium oxide green, 15-18 pts. wt. talc powder of 700-900 mesh, 8-11 pts. wt. precipitated barium sulfate of 700-900 mesh, 0.6 pt. wt. organic bentonite, 0.2-0.5 pt. wt. silane coupling agent, 1.5-1.9 pts. wt. polymer type dispersant, 0.1 pt. wt. 0.5-1.5% silicone oil, 2-5 pts. wt. dibutyl phthalate, 6-8 pts. wt. acetone, 8-10 pts. wt. butyl acetate, and 24.7-26.7 pts. wt. dimethylbenzene. An INDEPENDENT CLAIM is included for preparation of solar-heat-absorbing coating, which involves diluting the coupling agent, adding half the amount of solvent, stirring uniformly, adding absorbent to stainless steel barrel, rotating at 200-300 rpm for 20-30 minutes with addition of diluted silane coupling agent, mixing pretreated absorbent, dispersing agent, 60% resin, and anti-settling agent, mixing at high speed, dispersing in ball mill or sand mill to 30 mu m to obtain a millbase, adding plasticizer, leveling agent, remaining resin, and remaining solvent, stirring for 30-40 minutes, filtering with 100-mesh filter, and sealing in a container.
