Description of drawings
The structural representation of Fig. 1, equipment of the present invention.
Embodiment
As shown in Figure 1, a kind of equipment of vacuum evaporation silverskin, comprise vacuum evaporation plating machine 1, in described vacuum evaporation plating machine, be provided with deposited chamber 11, vacuum pump 13 and power set 12, deposited chamber interior 11 is provided with and unreels station 14, rolling station 15 and cooling roller volume 16, also be provided with high frequency induction heater 17 in the vacuum evaporation plating machine, be provided with plate washer 18 between high frequency induction heater 17 and the deposited chamber 11.
The method of vacuum evaporation silverskin: film substrate was coated adhesion layer on the film substrate surface before putting into vacuum evaporation plating machine, adhesion layer adopts the ultrapas spraying, film substrate to be plated with drum is contained in unreeling on the station of vacuum evaporation plating machine again, film is passed the cooling roller of vacuum evaporation plating machine and roll up, at last on the rolling station; Then vacuum pump carries out vacuumize degassing to deposited chamber, makes the vacuum tightness in the deposited chamber reach 4 * 10
-4More than the pa, then utilize high frequency induction heater that highly purified solid-state silver is heated to more than 1500 ℃, make it to melt and flash to gaseous state silver, and then startup winding film system, after film runs to certain speed, the baffle plate of opening again between deposited chamber and the high frequency induction heater is ejected into through on the film that has cooled off gaseous state silver particulate, because gaseous state silver is in the condition of high temperature, after in advance-25 ℃ of cooling rollers volumes of process cooling of film, it is front just because being subject to surrounding environment influence that silver-colored particulate is contacted with it, rapidly cooling, the silver particulate forms one deck continuously and the metallic silver layer of light at mobile film substrate surface deposition, protective film does not produce deformation simultaneously, at last by the film take-up of rolling station with the evaporation silverskin; Also need after the film take-up to coat ultrapas on the silverskin surface, ultrapas forms one deck external protection to reach anti-oxidation effect on the silverskin surface at once.
Evaporate process of the present invention should be noted that:
For removing the moisture of film: for the high planar water rate 1% of plastics film, must prevent and prevent making processes and silver-plated after adsorption moisture again, at first can utilize the method for vacuumize degassing that moisture is extracted out, or which kind of is advisable repeatedly to test comparison with the mode of the machine oven dry of tinting; For guaranteeing the silverskin immaculate of evaporation, with the input angle of evaporation initial stage silver atoms, density, evaporation rate is done suitable adjustment.
For the high-reflectivity that improves the fine silver film and increase optics: the smooth surface that chooses, clean base material, adjust wider visual angle, the image that must make reflection separates with the dazzle on surface, to obtain high optical efficiency and to increase optics to reach excellent reflection efficiency and photostabilization, weathering resistance.
The present invention is for strengthening the attachment fastness of evaporation silverskin on film, in advance at thin film coatings last layer ultrapas, to strengthen the degree of adhering between silver layer and plastics film, after the silverskin evaporation is finished again at silverskin surface spraying one deck ultrapas to reach the protection silver film, the effect of anti-oxidation must be surveyed its effect after being coated with repeatedly; In evaporate process, adopt vacuum pump that deposited chamber is carried out vacuumize degassing, make indoor vacuum tightness reach 4 * 10
-4More than the pa, utilize the mode of high-frequency induction heating that highly purified solid-state silver is melted under 1500 ℃ temperature and flash to gaseous state silver, start the winding film system, after film runs to certain speed, open baffle plate gaseous state silver particulate is ejected into through on the film that is cooled to-25 ℃ of capstan rolls; Because gaseous state silver is in the condition of high temperature, directly contact membrane can make it with temperature distortion, and after in advance cooling of film, it is front just because being subject to surrounding environment influence that silver-colored particulate is contacted with it, rapidly cooling, thus protective film does not produce deformation; The silver particulate is at mobile film substrate surface deposition, and cooling forms one deck continuously and the metallic silver layer of light; Because of product specification required, the thickness of metallic silver layer need to be controlled in definite scope, can can control in advance by velocity of evaporation, the translational speed of base material film and the vacuum tightness in the deposited chamber etc. of control argent the thickness of silvered film, have reflectivity and good in optical property, silverskin adhere firmly, immaculate characteristics.
