Abstract

The invention discloses low-radiation hollow glass with the ultraviolet blocking effect. The glass includes two glass substrates, and the two glass substrates are matched to form a hollow structure. The surface of at least one glass substrate is provided with a low-radiation composite functional film layer with the ultraviolet blocking effect. Compared with an existing ultraviolet blocking product, by absorbing and blocking ultraviolet rays, the hollow glass can achieve ultraviolet blocking through ultraviolet reflection, and the ultraviolet reflection intensity is greatly improved. Moreover,the hollow glass easily achieves large-area deposition, ultraviolet blocking is achieved, meanwhile the glass has a good thermal insulation effect. Compared with a PVB scheme and a double- film product, the product is lower in cost, suitable for ultraviolet protection of artworks and photography, and suitable for use in some airports and places requiring a large amount of ultraviolet reflection.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of optical coated glass, in particular to a low-radiation hollow glass with ultraviolet blocking effect. Background technique [0002] The solar spectrum is a continuous spectrum composed of light waves of different wavelengths, which can be divided into two parts: visible light and invisible light. Among them, visible light refers to light waves visible to human eyes with a wavelength range of 400-760nm. Visible light is divided into seven colors: red, orange, yellow, green, blue, blue, and purple after being scattered by a triangular prism. All visible light is concentrated When it rises, it shows white light. Invisible light can also be divided into two types: the area outside red light is called infrared, which usually refers to light waves with a wavelength greater than 760nm; the area outside purple light is called ultraviolet light, with a wavelength of 290-400nm. Stric...
