Embodiment 1

[0026] In the tin tank of the float glass production line, an online coating reactor with double inlet channels and exhaust on both sides is set above the glass ribbon. The glass ribbon temperature is 650°C, the glass plate speed is 505m / h, and the glass thickness is 5mm. , carbon dioxide, with nitrogen as the carrier to form the first mixed gas; the concentration of silane is 30%, the concentration of ethylene is 90%, the concentration of carbon dioxide is 2%, diluted with nitrogen; the volume percentage of silane: ethylene: carbon dioxide is 0.001:0.02:1.5 , the rest is nitrogen; the flow rate of the mixed gas is controlled at 5 liters / minute; triethyl phosphate is vaporized by heating, and nitrogen is used as the carrier gas to form the second mixed gas. The molar concentration of triethyl phosphate is 0.001mol%, and the rest are Nitrogen, the flow rate of the mixed gas is 10 liters / minute. The two-way mixed gas is ejected from the two channels of the reactor at the same ti...

Embodiment 2

[0030]Repeat the above process, in the tin tank of the float glass production line, use the online coating reactor at the temperature of the glass ribbon at 645°C, the speed of the glass plate at 420m / h, and the thickness of the glass at 6mm. Mixed gas all the way; the concentration of silane is 20%, the concentration of ethylene is 95%, and the concentration of carbon dioxide is 15%, diluted with nitrogen; the volume percentage of silane: ethylene: carbon dioxide is 0.009:0.01:2.3, and the rest is nitrogen; the flow rate of the mixed gas Generally controlled at 20 liters / minute. The triethyl phosphate is heated and vaporized, and nitrogen is used as a carrier gas to form a second mixed gas. The molar concentration of triethyl phosphate is 0.007 mol%, and the rest is nitrogen. The flow rate of the mixed gas is 25 liters / minute. The two-way mixed gas is ejected from the two channels of the reactor at the same time, and is pyrolyzed and superimposed on the glass to form a refrac...

Embodiment 3

[0034] Repeat the above process, in the tin tank of the float glass production line, use the online coating reactor at the temperature of the glass ribbon at 645°C, the speed of the glass plate at 420m / h, and the thickness of the glass at 6mm. Mixed gas all the way; the concentration of silane is 30%, the concentration of ethylene is 100%, and the concentration of carbon dioxide is 30%, diluted with nitrogen; the volume percentage of silane: ethylene: carbon dioxide is 0.01:0.02:2.5, and the rest is nitrogen; the flow rate of the mixed gas Generally controlled at 35 liters / minute. The triethyl phosphate is heated and vaporized, and nitrogen is used as a carrier gas to form a second mixed gas. The molar concentration of triethyl phosphate is 0.02 mol%, and the rest is nitrogen. The flow rate of the mixed gas is 35 liters / minute. The two-way mixed gas is ejected from the two channels of the reactor at the same time, and is pyrolyzed and superimposed on the glass to form a refrac...

Abstract

The invention relates to a multi-color low-radiation sunlight control coated glass and a preparation method thereof, which solves the problems of high color-changing cost, long color-changing cycle and poor energy-saving effect of the product existing in the existing method of producing colored glass. A multi-color low-radiation solar control coated glass, which has a film structure, the film structure is composed of a bottom layer and an upper layer of two films, the bottom layer is a refractive index adjustment layer, and its composition is silicon dioxide, doped with carbon and phosphorus; The upper layer is a colored low-emissivity layer, and its composition is a tin oxide layer doped with fluorine and boron. The invention can be used for preparing multi-color low-radiation solar control coated glass.

Description

technical field [0001] The invention relates to glass and its preparation method, in particular to providing a multi-color low-radiation sunlight control coating glass and its preparation method by using chemical vapor deposition technology. Background technique [0002] Stained glass is a kind of energy-saving decorative glass that can not only absorb heat rays in sunlight significantly, but also maintain good transparency. Stained glass comes in different colors and is also known as tinted glass. There are various kinds of stained glass, such as blue, brown, gray, green, gold and so on. [0003] Stained glass can effectively absorb the sun's radiant heat and produce a "cold room effect" to achieve the effect of heat insulation and energy saving. It can soften the sunlight passing through the building and avoid glare; it can effectively absorb the sun's ultraviolet rays and effectively prevent fading and deterioration of indoor items; its color is bright and durable; it c...
