ADVANTAGE - The solar water heater insulation box has excellent heat absorption characteristics.    DETAILED DESCRIPTION - A solar water heater insulation box consists of storage tank including liner, shell, and water inlet and outlet, thermal layer including electric heating network and temperature sensor, coating layer provided on thermal layer, thermal-insulating layer provided on adhesive layer of the coating layer, control layer provided on the thermal-insulating layer (a), thermal-insulating layer (a), and protective layer provided on thermal-insulation layer (b). The control layer is electrically connected to solar battery, and a controller. The controller is electrically connected to temperature sensor which measures the electric heating network temperature signal for controlling the electric heating network. The thermal layer contains 20 wt.% polyvinyl acetate emulsion, 21 wt.% styrene-acrylic emulsion, 5 wt.% fluorosilicone rubber, 20 wt.% sepiolite powder, 7 wt.% glass fiber, 2 wt.% flame retardant, 1.6 wt.% bentonite, 1 wt.% film-forming agent, 0.05 wt.% dispersing agent and 22.35 wt.% water. The thermal-insulating layer (a) contains insulation particles are made of hollow nano-material, and has thickness of 3-5 cm. The thermal-insulating layer (b) contains 80 wt.% insulation particles, 2 wt.% fibrous material, 10 wt.% cementitious material, 5 wt.% activated nano filler and 3 wt.% anti-radiation material and has thickness of 2-4 cm.
