Abstract

The invention relates to temperable film-coated glass having a composite functional thin film and a preparation method thereof, and is characterized in that an outermost layer is deposited with an eighth film layer Si3NxOy layer; a heat reflection interface is formed between the eighth film layer Si3NxOy layer and a seventh film layer Si3N4 layer. The method comprises the steps: successively carrying out magnetron sputtering deposition of a first film layer Si3N4 layer, a second film layer AZO layer, a third film layer NiCr layer, a fourth film layer Ag layer, a fifth film layer NiCr layer, a sixth film layer AZO layer, the seventh film layer Si3N4 layer and the eighth film layer Si3NxOy layer on a fresh glass substrate. The temperable film-coated glass can effectively limit the incident dose of solar light radiation; the film layer structure matching improves the film surface strength and the safety of the product, and the product can be tempered allopatrically; the highest point of a visible light part transmittance ratio curve is more than 50%, the highest point of a near infrared part non film-coated surface reflection curve is more than 70%, the highest point of a film-coated surface reflection curve is more than 90%, the radiation rate is 0.06-0.10, and the infrared heat reflectivity is more than or equal to 85%. The temperable film-coated glass has the advantages of low preparation cost, wide applicability, allopatric tempering and the like.

Description

technical field [0001] The invention belongs to the technical field of energy-saving glass, and in particular relates to a temperable coated glass with a composite functional film and a preparation method thereof. Background technique [0002] Existing coated glass with heat reflection or low radiation function can be prepared by online or offline method and applied to real estate projects in different thermal climate zones to achieve building energy saving. Under normal circumstances, heat reflective glass is suitable for tropical, subtropical and warm regions with long summers and short winters. Because of its shading effect, it often affects the indoor lighting effect; and Low-E glass is also called low-emissivity coated glass. It can be applied to a wider range of high, middle and low latitude areas. Its coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, thereby filtering sunlight into a cold lig...
