Abstract
The invention discloses low-radiation temperable double-silver LOW-E glass, which comprises a glass substrate, wherein nine film layers are adjacently compounded in sequence on the composite surface of the glass substrate from inside to outside. The low-radiation temperable double-silver LOW-E glass is characterized in that: a first film layer, i.e., an innermost layer is an Si3N4 layer; a second layer is a TiO2 layer; a third layer is a ZnAlOx layer; a fourth layer is an Ag layer; a fifth layer is a TiO2 layer; a sixth layer is a ZnAlOx layer; a seventh layer is an Ag layer; an eighth layer is an NiCrOx layer; and a ninth layer is an Si3N4 layer. The low-radiation temperable double-silver LOW-E glass has the advantages of low radiation rate which is less than or equal to 0.03, good energy saving effect, lower shading coefficient in comparison to the same type of product with the same penetration rate, avoidance of the situation of damaging the film layers when the temperature is 700 DEG C in maximum in a tempering heating process, small color difference after tempering and high film layer uniformity.
Description
[technical field]
The present invention relates to a kind of coated glass, but especially relate to the two silver-colored LOW-E glass of a kind of low radiation tempering.
[background technology]
Glass is the indispensable integral part of buildings and automobile, is bearing many important function, comprises the outward appearance of beautifying constructure and automobile, daylighting and give the indoor open visual field of bringing.But common coated glass sunlight transmitance is general, and ir reflectance is very low, and most of sunshine sees through glass and in the inlet chamber, thus heating object, and the energy of these indoor objects can lose through glass with forms of radiation.And the radiant ratio of common coated glass is high, and energy-saving effect is poor, and existing pair of silver low radiation (LOW-E) but coated glass tempering processing few occur rete easily after the tempering heating to damage, aberration is big before and after the tempering, membrane uniformity is poor.
For this reason, the inventor has designed this patent, to overcome the problems referred to above.
[summary of the invention]
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of radiant ratio low, good energy-conserving effect rete can not occur and damage after the tempering heating, and aberration is little before and after the tempering, but membrane uniformity good the two silver-colored LOW-E glass of low radiation tempering.
The objective of the invention is to realize like this:
But the two silver-colored LOW-E glass of a kind of low radiation tempering include glass substrate, on the composite surface of glass substrate, are adjacent to successively from inside to outside be compounded with nine retes, and it is characterized in that: wherein first rete is that innermost layer is Si
