Low radiation coated hollow glass

The utility model provides a low radiation coated hollow glass, including glass substrate and the function rete on glass substrate, glass substrate's quantity is two, form hollow layer among them, be filled with inert gas in the hollow layer, and be fixed with the bracing piece, glass substrate's interior uniform distribution has the spherical chamber that holds, the bracing piece is together fixed with glass substrate through hold the fixed ball of intracavity embedding rubber in the sphere, a glass substrate's surface is equipped with first dielectric layer in proper order, first protective layer, first silver alloy layer, first barrier layer, the second protective layer, top layer dielectric layer and top layer protective layer, first silver alloy layer be silver with the gold and copper in at least an alloy, the top layer protective layer is the siC rete, the top layer dielectric layer is znO or tiOx rete. Form the infrared external reflection with the silver alloy, improve the water -fast vapour nature of humidity, keep strong infrared external reflection ability and low radiant ratio, the stress that bracing piece dispersion glass received improves glass intensity, thermal -insulated, the sound insulation of inert gas, simple structure is reasonable.
