The invention discloses a thermal insulating sterilization type coating for glass doors. The thermal insulating sterilization type coating is characterized by being prepared from the following raw materials in parts by weight: 38-42 parts of aqueous epoxy resin, 12-15 parts of aqueous alkyd resin, 11-14 parts of acrylic resin emulsion, 0.3-0.5 part of a leveling agent BYK-307, 0.2-0.4 part of gas phase nanosilicon dioxide, 1-2 parts of butyl stearate, 0.3-0.5 part of methyl glycidyl acrylate, 0.2-0.3 part of cashew nut oil, 1-3 parts of zinc powder, 0.2-0.3 part of octadecanamide, 1-3 parts of dipropylene glycol butyl ether, 0.5-1.0 part of a silane coupling agent KH, 0.2-0.4 part of a polysiloxane defoaming agent, 0.2-0.4 part of a dispersing agent BYK-415, 0.3-0.5 part of fatty alcohol sodium succinate, 1-2 parts of a polymercaptan curing agent, 1-2 parts of aluminum silicate powder, 0.4-0.8 part of sodium phytate, 3-5 parts of a modified nano titania photocatalyst, 1-2 parts of pigment and 12-15 parts of deionized water. By adopting the thermal insulating sterilization type coating disclosed by the invention, a coated film is smooth and flat, hard in hardness, free of peeling or dropping, resistant to brushing and washing and good in water resistance after being cured, the added aluminum silicate powder has a function of reflection thermal insulation, the added zinc powder has the functions of corrosion resistance, rusting resistance and aging resistance, and due to addition of the modified aluminum silicate powder, the self-cleaning property, the antifouling property, the anti-mildew property, the air purification property and the like of the coating are improved.
