Description
Technical field
The utility model belongs to glass technology field, is specifically related to a kind of coated glass.
Background technology
Off-line low-radiation film one functional layer is silver layer, utilizes it to the high reverse--bias of the high transmission of solar energy shortwave and mid and far infrared ripple to reach the object of insulation.In order to obtain the more excellent product of performance; the thickness (do not increase merely certain layer of silver-colored thickness, otherwise glass transmitance is very low, is realized by the number of plies increasing silver) of silver layer will be increased; the increase of silver layer number, needs to increase many dielectric layers and protective layer accordingly.Every one deck all needs magnetic control sputtering cathode material to obtain, and this just needs a lot of negative electrode to support.Many producers fund that costs a lot of money builds the many production lines of negative electrode quantity, and the home made production line of 45 cathode arrangement needs more than hundred million yuan.
The cooperation of multiple rete often causes the color value excursion of formed coated glass under different viewing angle very large, namely interference colours can change along with the change of viewing angle, when the coated glass with above-mentioned multiple film layer is applied on building, macroscopically show as: when observer stands on a certain fixing point, the coated glass observed in its visual field can present different viewing angles between observer, make observer to the cognitive fact for multicolour of the color of glass on whole building, facade is even made to present the huge red green of contrast in the eyes of a viewer color, like this not only bad for people to the observation of building and the aesthetic destroying the solid colour that building should have.
Because off-line low emissivity glass all needs synthesis, double glazing uses, and general small processing factory does not possess the ability of producing off-line low emissivity glass, oneself can only be changed and cut out, grind limit, the glass external coordination plated film that tempering is complete, then transports oneself synthesis hollow back, adds cost.Can realize strange land processing by the two silver products of tempering, small processing factory can buy oneself following process by the two silver products of tempering the large space of a whole page, but this type of product price is higher on the one hand, on the other hand because rete is more, each rete has micro-variations in tempering heating process, make the glass colour change before and after tempering obvious, easily occur misalignment.
Off-line low emissivity glass product in the market; in order to improve its heat-proof quality; often increase the quantity of silver layer; make two silver or three the silver medals even product of four silver medals; other retes of multilayer must be increased accordingly in order to protect and to regulate appearance property while silver layer quantity increases; this will ask production line to have abundant negative electrode, require very large to equipment scale.Secondly, the rete of heterogeneity is superimposed in a large number, can cause the appearance of interference colour, and namely people observes glass of building appearance color and can change along with the change of viewing angle, facade is presented " aberration ", destroys the aesthetic of solid colour.Again, because general small-size glass processing factory scale limit, requiring that low emissivity glass has can strange land processing characteristics, and appearance property change obviously, easily can occur misalignment before and after two (three) silver products tempering of tempering.
Patent CN101955324A discloses a kind of low emissivity glass, and the side of glass substrate described in it is from inside to outside disposed with first medium layer, copper film layer, the first barrier layer, second dielectric layer, silver film, the second barrier layer and the 3rd dielectric layer.The feature of its patent is the film group that off-line plating contains layers of copper on ordinary plate glass, muted color (generally on the market based on bluish-green film) can be reached on the one hand, layers of copper has the far performance of certain reflection on the other hand, reach the performance of Low emissivity, but, the heat-proof quality of this glass structure does not improve, poor.
Patent CN104210183A discloses a kind of single silver-colored radiation coated glass capable of being toughened, and its glass substrate surface is upwards coated with silicon nitride film layer successively from bottom, chromium rete, nickel chromium triangle rete, silver film, nickel chromium triangle rete and silicon nitride film layer.Be characterized in off-line plating Dan Yinke tempering film group on ordinary plate glass, before and after tempering, transmitance change is less, but its energy saving is poor.
Utility model content
There is misalignment for coated glass of the prior art in the utility model, heat-proof quality is poor, the problem that energy saving is poor, proposes a kind of coated glass.
A kind of coated glass, adopt online low emissivity glass to be substrate, the side of substrate is coated with online rete, the opposite side plating first medium layer successively of substrate, the first protective layer, silver layer, the second protective layer, second dielectric layer.
Described first medium layer, the first protective layer, silver layer, the second protective layer and second dielectric layer form off-line rete.
Further, the thickness of described online rete is 60-200 nanometer.
Further, the thickness of described first medium layer is 15-45 nanometer.
Further, the thickness of described first protective layer is 5-10 nanometer.
Further, the thickness of described silver layer is 4-8 nanometer.
Further, the thickness of described second protective layer is 5-10 nanometer.
Further, the thickness of described second dielectric layer is 30-50 nanometer.
The beneficial effects of the utility model: coated glass of the present utility model is can tempering list silver film at another side plating one deck of online low emissivity glass rete, forming glass one side is on-line coating, one side is that off-line coated double-sided coating can safety glass, film layer structure is simple, low for equipment requirements, produce and easy to control in following process process, heat-proof quality is suitable with two silver products.
