The invention discloses a preparation technology of light blue low-reflection solar control film-plating glass. According to the preparation technology, a tin source, an antimony source, O2, H2O and carrier gas are used as reaction gas, two film-plating reactors are used for plating a first antimony doped tin dioxide layer and a second antimony doped tin dioxide layer with appropriate antimony doped quantity and appropriate thickness on the surface of a glass substrate. The technology disclosed by the invention is simple in steps, stable and controllable in process, low in production cost and suitable for industrialized application; prepared products are high in transmissivity of visible light and low in reflectivity, do not generate light pollution, and have favorable acid resistance, alkali resistance and wear resistance; and deep processing of toughening, hot bending, making an interlayer and the like can be easily performed on the prepared products, and besides, requirements of people for aesthetic feeling during design and use can be met.
