| abstract |
The invention discloses a formula of a heat-insulating material for a water tank of a solar water heater, which is prepared from the following raw materials in parts by weight: 60-70 parts of glycerol glucoside polyether polyol, 5-10 parts of chitosan, 8-15 parts of dimethyl methyl phosphate, 8-15 parts of titanium dioxide, 5-10 parts of aluminum silicate and 2-10 parts of calcium chloride. The invention is used on the surface of the water tank of the solar water heater, has high heat absorption rate and improves the heating efficiency. The material of the invention overcomes the defect of large shrinkage after foaming molding, avoids the deformation of the water tank and ensures the heat preservation performance of the water tank of the water heater. |
