Abstract

The invention discloses a heat absorbent for solar water heaters and a production method. The heat absorbent for the solar water heaters is prepared from the following raw material components according to a weight ratio: 20 to 30 of carbon powder, 2 to 8 of zinc powder, 15 to 25 of titanium dioxide, 10 to 15 of aluminium silicate, 7 to 14 of calcium chloride, 3 to 8 of polyvinyl alcohol, 5 to 10 of calcium carbonate and 5 to 10 of sodium silicate. After the materials are mixed according to the weight of each component, 5 to 10 of materials and 90 to 95 of water are uniformly stirred for dilution, so that the heat-absorbing material for the solar water heaters is produced. According to the invention, the heat absorption rate is high, and the heat absorption effect for sunlight is ideal. Theheat absorbent for the solar water heaters is durable, having a long service life which is prolonged by 30 percent or more. The application range is wide, and the invention is easy to popularize.

Description

technical field [0001] The invention relates to a heat-absorbing material, in particular to a heat-absorbing material for a solar water heater. Background technique [0002] At present, the heat-absorbing materials of solar water heaters use dull paint, etc. Although these materials are low in cost and easy to operate, their heat absorption effect on sunlight is not very ideal, and the heat absorption rate is not very high, which directly affects the performance of solar water heaters. Promote apps. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies of the prior art and provide a solar water heater heat absorbing agent with high heat absorption rate and long service life. [0004] The present invention is formulated from the following raw material components and weight ratios: carbon powder 20-30, zinc powder 2-8, titanium dioxide 15-25, aluminum silicate 10-15, calcium chloride 7-14, polyvinyl alcohol 3-8, calcium carbonate 5...
