Description
Technical field
The present invention relates to energy-saving material, relate in particular to a kind of thermal insulation film.
Background technology
For reaching energy-conservation purpose,, often require when satisfying the printing opacity requirement, to require ornament materials to have effect of heat insulation concurrently in occasions such as house decoratons.Means commonly used are to paste thermal insulation film on materials such as glass.
Film is the habitual addresses of people to pad pasting class material, is not to be that thickness to film limits to some extent.
Existing thermal insulation film generally adopts and is coated with multilayer film on the matrix, the film structure of multilayer film is generally " medium-metal-dielectric " or " medium-metal-dielectric-metal-dielectric ", wherein metal generally adopts silver, and medium generally adopts the nitride of the oxide of titanium, zirconium, zinc, indium, tin, tungsten etc. and titanium, silicon.The corrosion resistance of silver is relatively poor, has increased the erosion-resisting difficulty of manufacture process thus, also makes the life-span of thermal isolation film very limited.Silver layer can play heat insulation effect, but its effect is relatively poor, and is impracticable.The silver alloy that also has human to mix the 15%-20% gold replaces silver layer, effect of heat insulation is improved, and the absorptivity of ultraviolet light is the highest can to reach 90%-95%, but the light transmittance of visible light descends to some extent, the electrum of aforementioned ratio, its light transmittance are generally below 85%.Simultaneously, the cost of gold is very high, thereby the aforementioned films architecture can only be applicable to grade places, as car vehicle window pad pasting, be not suitable for civilian, as house decoraton.High cost, light transmittance is undesirable in addition, makes the film with aforementioned films system still can not generally promote, and remains to be improved.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part and a kind of low cost, thermal insulation film that the visible light translucent effect is good are provided.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of thermal insulation film, the plural layers that comprise transparent base material and be plated on the base material constitute, it is characterized in that: the film structure of these plural layers is ZAO-AgAu-TiO2-AgAu-ZAO, wherein, the ZAO rete is a zinc oxide aluminum, the AgAu rete is an electrum, and the content of Au in AgAu is 2%-6%, and the TiO2 rete is a titanium dioxide.
Thermal insulation film is characterized in that: the content of described Au in AgAu is 4%-5%.
Thermal insulation film is characterized in that: the content of described Au in AgAu is 4.5%.
Thermal insulation film is characterized in that: the thickness of AgAu rete is 2nm-30nm.
Thermal insulation film is characterized in that: the thickness of AgAu rete is 4nm-8nm.
Thermal insulation film is characterized in that: described base material is a flexible parent metal.
Thermal insulation film is characterized in that: described base material is the PET film.
The thermal insulation film that the present invention relates to, the content of the Au of AgAu only is 2%-6% in its assembly of thin films, compared with prior art, and the AgAu of same thickness, the use of Au has reduced about 2/3rds, greatly reduces cost.Because Au content lower (the visible light partial reflectance is low), the light transmittance of thermal isolation film increases, and compared with prior art, it is brighter that thermal insulation film seems.The ZAO-AgAu-TiO2-AgAu-ZAO film structure, the ectonexine medium adopts different materials, forms real double thermal insulation, and with comparing of the single medium of ectonexine, effect of heat insulation is better.ZAO and the AgAu combination that contains Au2%-6%, its two-way effect of heat insulation all significantly improves more than or equal to the 760nm wavelength time, because the adding of Au is arranged, it is to visible optical transmission and all much higher than Ag layer to the obstruct of infrared waves.Therefore, compared with prior art, thermal insulation film cost of the present invention is low, visible light transmittance rate is high, effect of heat insulation is better.

Fig. 1 is the schematic cross-section of first embodiment of the invention.
Fig. 2 is a first embodiment of the invention rejection rate curve map.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to figure 1, first embodiment of the present invention is a kind of thermal insulation film, the plural layers that comprise transparent base material 106 and be plated on the base material constitute, the film structure of these plural layers is ZAO-AgAu-TiO2-AgAu-ZAO, as shown in Figure 1, by skin to internal layer, be followed successively by a ZAO rete 101, the one AuAg layer 102, TiO2 layer 103, the 2nd AuAg layer 104, the 2nd ZAO layer 105, base material 106, wherein, the one ZAO rete 101 and the 2nd ZAO rete 105 are zinc oxide aluminum, the one AgAu rete 102 and the 2nd AgAu rete 104 are electrum, and the content of Au in AgAu is 4.5%, and TiO2 rete 103 is a titanium dioxide.The thickness of the one AgAu rete 102 and the 2nd AgAu rete 104 is 7nm.The thickness of the one ZAO rete 101 and the 2nd ZAO rete 105 is 20nm, and the thickness of TiO2 rete 103 is 12nm, and described base material 106 is a flexible parent metal, is the PET film.Each layer can adopt vacuum coating technology to be coated on the PET film.Properties of product, visible light transmittance rate 85%, the infrared waves rejection rate is greater than 96%, with reference to figure 2, it is the thermal resistance rate curve comparison diagram of the suitable film product of present embodiment product and thickness of coating with ITO-AgAu-ITO-AgAu-ITO film structure, transverse axis is represented wavelength among the figure, the longitudinal axis is represented rejection rate, wherein the Au content of the AgAu coating of ITO-AgAu-ITO-AgAu-ITO film structure is 18%, and no matter the present invention's thermal isolation film is that the rejection rate of visible light transmittance rate and infrared waves all is better than contrast product.
