The invention relates to heat insulation glass used for an ultraviolet absorption window. The heat insulation glass comprises a glass body, and the glass body comprises a glass base material and a coloring agent, wherein the coloring agent is prepared from 0.7-1.6 wt% of Fe2O3, 0.1-1.2 wt% of CeO2 and 0-1.5 wt% of TiO2; a heat insulation layer is arranged on the surface of the glass body and is prepared from, by weight, 70-80 parts of water, 85-100 parts of rutile titanium dioxide, 35-40 parts of hollow beads, 10-12 parts of far infrared ceramic powder, 6-10 parts of dispersant and 230-250 parts of pure acrylic elastic emulsion. The heat insulation glass used for the ultraviolet absorption window is high in heat insulating property, capable of effectively blocking sunlight to ensure indoor shady and cool environment and capable of effectively preventing erosion to the human body by ultraviolet ray and has unique color and tonality.
