Background technology
Along with the development of science and technology and the arrival in the whole world " energy crisis " epoch, solar film, i.e. solar control film is in continuous development.First generation solar film is in the coating of the thirties in 20th century and combination process film, is commonly called as tea paper, mainly is to be used for shading, does not possess heat-blocking action basically.The second generation is the dyeing film of the sixties in 20th century, by adding pigment, obtains the film of different colours, but does not have heat-blocking action, and visible light transmissivity is low, poor definition, fade easily.The third generation is the vacuum evaporation coating of early 1990s, aluminium-vapour deposition on base material, is reached effect of heat insulation, but visible light transmissive is low, and reflective height influences visual field comfortableness.The 4th generation was the metal magnetic control sputtered film of late 1990s; With metal material uniform depositions such as nickel, silver, titanium, gold on the PET base material; Has effect of heat insulation preferably; Also have definition height, reflective characteristics such as low, but exist metal level to be prone to oxidation, can intercept the GPS shortcomings such as interior wireless telecommunication system signal of waiting for bus.Along with the fast development of car industry and the construction of modern high buildings and large mansions, the non-plated film glass pane of automobile more than 70% and high buildings and large mansions all will paste solar film, simultaneously to having higher requirement in heat insulation, safety, color and luster and service life of solar film etc.Therefore need badly a kind of novel nano ceramics solar film is provided.
Summary of the invention
The technical problem that the present invention will solve provides the nano ceramics solar film that a kind of good heat-insulation effect, color and luster are good, be difficult for oxidation, long service life.
For solving the problems of the technologies described above, a kind of nano ceramics solar film of the present invention, magnetron sputtering is coated with ground floor titanium dioxide film, second layer titanium nitride film and the 3rd layer of titanium dioxide film successively on the one side of base material PET.
The thickness of base material PET is 23 μ m～50 μ m.
The thickness of ground floor titanium dioxide film is 26nm～38nm.
The thickness of second layer titanium nitride film is 20nm～26nm.
The thickness of the 3rd layer of titanium dioxide film is 26nm～38nm.
Ground floor titanium dioxide film, second layer titanium nitride film and the 3rd layer of titanium dioxide film all adopt intermediate frequency reaction magnetocontrol sputtering twin target method to be coated with.
The present invention's reaction magnetocontrol sputtering on flexible parent metal PET is coated with ground floor titanium dioxide film, second layer titanium nitride film and the 3rd layer of titanium dioxide film successively; This nano ceramics solar film has good spectrum and selects permeability; At visible region higher transmittance (＞70%) is arranged, very high reflectivity is arranged, intercepted infrared ray at infrared region; So just reduced the source of heat, realized but not influencing heat insulation the time transmitance of visible light.As far as automobile and building; The pad pasting that this sunlight control film is processed; Be attached on the window of automobile and building and can reduce the energy consumption of turning on the aircondition effectively; Under the environment of current energy scarcity, be a kind of novel good energy-conservation environment-friendly materials, significant to energy savings and environmental protection.
And titanium dioxide and titanium nitride at room temperature have very high chemical stability, are difficult for oxidation, and generally speaking, it and oxygen, water, steam, hydrochloric acid, sulfuric acid etc. all do not react, and stable performance is will never fade, variable color, long perfomance life.
The present invention also overcome the 4th substituting metal magnetron sputtering film can intercept GPS wait for bus in the shortcoming of wireless telecommunication system signal, guaranteed indoor or car in the wireless communication signal quality.
