Problems solved by technology

[0007] The purpose of the present invention is to overcome the problems in the prior art that ordinary glass has good optical rotation performance and poor heat insulation ability, especially the lack of "reflected heat" heat insulation and cooling ability for "sunlight heat radiation", even if the ordinary glass is made into Hollow, vacuum tempered transparent glass, still has no "reflect sunlight heat", heat insulation "self-cleaning" function, and the shortcomings of difficult cleaning

preparation example Construction

[0065] Further, the present invention also provides a method for preparing the above-mentioned heat-insulating self-cleaning nano-composite glass with a double-layer hollow structure, comprising the following steps:

[0066] (1) Select two pieces of transparent glass, preferably two pieces of transparent tempered glass, and evenly spray nanometer self-cleaning composite coating on the surface of the first piece of glass, with a coating thickness of 10 μm to 15 μm.

[0067] (2) Wipe the surface of the second piece of glass clean, keep its inner surface (the surface near the indoor side) as it is, and spray nanometer self-cleaning paint on the outer surface of the tempered glass (the surface near the outdoor side), with a thickness of 10 μm ~15 μm. Transparent tempered glass has good strength, is not easy to break, and has better stability and reliability. The surface of the transparent tempered glass sprayed with self-cleaning nano-composite paint can be the outer surface of t...

Embodiment 1

[0077] Heat-insulating self-cleaning nano-composite glass has two layers of basic glass, which are combined into two layers of insulating glass through spacers. The outer surface of the glass on the indoor side (closer to the indoor side) has a nano-coating for reflecting sunlight and heat insulation (also called a heat-insulating nano-coating or a nano-insulation layer). The composition of the nano heat insulation layer is: nano titanium dioxide (TiO 2 ) 28%, nano silicon dioxide (SiO 2) 17%, nano-antimony tin oxide (ATO) 8%, fluororesin 7%, and the rest is glue polymer material for curing. Among them, the outer surface of the glass on the outdoor side (the side close to the outdoor) has a self-cleaning nano-coating (also called a nano-self-cleaning layer). The composition of the nano self-cleaning layer contains: nano titanium dioxide (TiO 2 ) 22%, water-based fluororesin 12%, nano silicon dioxide (SiO 2 ) 13%, nano zinc oxide (ZnO) 7%, nano antimony tin oxide (ATO) 5%. ...

Embodiment 2

[0079] The heat-insulating self-cleaning nano-composite glass similar to Example 1 has only one layer of basic glass, and the glass surface on the indoor side (the side close to the indoor) has a nano-insulation layer. The composition of the nano heat insulation layer is: nano titanium dioxide (TiO 2 ) 25%, nano silicon dioxide (SiO 2 ) 18%, nano-antimony tin oxide (ATO) 9%, nano-fluorine resin 6%, and the rest is the adhesive polymer material for curing. The glass surface on the outdoor side has a nanometer self-cleaning layer. The composition of the nano self-cleaning layer contains: nano titanium dioxide (TiO 2 ) 24%, water-based fluororesin 13%, nano silicon dioxide (SiO 2 ) 11%, nano zinc oxide (ZnO) 6%, nano antimony tin oxide (ATO) 7%.

Abstract

Heat-insulating self-cleaning nanometer composite glass reflecting sunlight heat is disclosed. The composite glass includes one or more base glass layers. The surface of at least one base glass layer is provided with a sunlight-heat-reflecting heat-insulating nanometer coating. The surface of at least one base glass layer has a self-cleaning nanometer coating. The sunlight-heat-reflecting heat-insulating nanometer coating comprises 25-30% of nanometer titanium dioxide (TiO2), 15-18% of nanometer silica (SiO2), 5-10% of nanometer antimony tin oxide (ATO) and 5-10% of fluororesin. The self-cleaning nanometer coating comprises 20-25% of nanometer titanium dioxide (TiO2), 10-15% of waterborne fluororesin, 10-15% of nanometer silica (SiO2), 5-8% of nanometer zinc oxide (ZnO) and 5-8% of nanometer antimony tin oxide (ATO). The composite glass has excellent performance, high transmission of light in the visible light zone, and excellent reflection barrier properties for infrared light and ultraviolet, and can achieve effects of heat insulation in summer and heat preservation in winter.

Description

technical field [0001] The invention relates to a glass product for energy saving and emission reduction, in particular to a self-cleaning nano-composite multifunctional glass (product) reflecting sunlight, heat insulation, and self-cleaning. The windows processed by it can significantly reduce the room temperature in summer, keep warm and self-cleaning in winter, and keep bright as new forever. It has outstanding significance for reducing energy consumption and cleaning costs, and is a new type of energy-saving and environmentally friendly product. At the same time, the present invention also relates to the main method for preparing the glass product and related derivative products. Background technique [0002] Glass is an amorphous solid with irregular structure formed by melting quartz sand and other substances. The main component of ordinary glass is silicon dioxide. According to written records, as early as the 4th century AD, the Romans calcined and melted crystal m...
