Description

Technical Field

[0001] The present invention belongs to the technical field of decorative films, and in particular relates to a dimming decorative film, a light-transmitting component, a window, and a carrier. Background Art

[0003] In the context of overall shrinking auto sales, new energy vehicle sales have achieved substantial growth, which has shown that new energy vehicles are accelerating the trend of replacing traditional fuel vehicles. However, since the battery packs of new energy vehicles are installed in the chassis, in order to compress the space, mainstream panoramic skylights are not equipped with sunshades, and the panoramic skylights cannot be opened. This results in the hot sun shining directly into the car from the top when the new energy vehicle is driving in the summer. Even if the air conditioner in the car is turned to the highest setting, the owner and passengers still feel like they are in an oven.

[0004] From Lantu FREE, AION S Plus, to Zeekr 001, more and more automakers are applying dimming technology to car sunroofs. This is not only a new choice under the trend of car intelligence, but also the best solution for panoramic sunroofs in the era of new energy vehicles. The chassis battery pack of new energy vehicles reduces the vertical space in the car, and the traditional sunroof glass is relatively thick. Coupled with the sunshade, the workshop space becomes more crowded and the driver's field of vision becomes narrower.

[0005] Dimming decorative film can be applied to car sunroofs, side windows, rearview mirrors, architectural glass films and other scenes. It refers to the phenomenon that the optical properties of the material can stably and reversibly change color under the action of an external electric field. In order to insulate, it will absorb some solar energy, and the glass will reflect some infrared rays. When the sunlight becomes very glaring, the glass will turn black, but if you want to see the scenery outside, you can brighten the glass. It can respond to external conditions to change different brightness, such as sunrise, sunset, cloudy and rainy, sunny days, etc. In the case of strong sunlight, it can block most of the sunlight and heat like a parasol, quickly adjust the total amount of light entering the car, and provide a clear external view. Color-changing dimmer film plays an important role in improving driving experience, enhancing driver and passenger comfort, and adjusting the brightness of the car. By automatically or manually controlling the car glass, its optical and thermal properties can be dynamically changed.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a dimming decorative film, a light-transmitting component, a window, and a carrier.

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] The neutral to cool tone dimming decorative film of the present invention comprises a substrate layer, which may be a PET layer, a transparent PI layer, a TAC layer, a COP layer or a PC layer, and has a thickness of 5.7-250 μm. An upper primer layer and a lower primer layer are respectively provided on both sides of the substrate layer through a coating process, and an upper IM layer and a lower IM layer are respectively provided on the upper primer layer and the lower primer layer through a coating process, and the upper IM layer and the lower IM layer are both low-refractive acrylic resin coating liquids, the upper IM layer has a coating thickness of 40-900 nm, and the lower IM layer has a coating thickness of 20-900 nm, and after coating, the upper IM layer is laminated to the lower primer layer for 30-180 nm. 8μm high temperature protective film is used to ensure the appearance protection and coating stability of the film surface during magnetron sputtering coating. A primer layer is plated on the upper IM layer through magnetron sputtering process to increase the adhesion of the bottom layer. The thickness of the primer layer is (0.2-20nm). The primer layer can be SiO2, Si, Al2O3, MgF2, SiO, HfO2, SnO2, Y2O3. A 1-30nm titanium dioxide layer is plated on the primer layer to change the color. A 10-60nm silicon dioxide layer is plated on the titanium dioxide layer to reduce reflection. A 100-60nm silicon dioxide layer is plated on the silicon dioxide layer to increase the conductivity. -400nm first indium tin oxide layer (first ITO layer) and second indium tin oxide layer (second ITO layer), both need to use different proportions of indium tin target materials, otherwise the aging crystallization after film formation will not be crystallized, so different doping ratios of indium tin targets are used for mixed coating, indium tin target ratio (here the first ITO layer is plated with ITO indium accounting for 80-99%, tin accounting for 1-20%, the second ITO layer is plated with ITO indium accounting for 85-98%, tin accounting for 2-15%), the above is dry magnetron vacuum coating sputtering, the vacuum degree reaches below 1.0-4pa, and the water vapor value reaches 9.0-5p a, target sputtering can be turned on. The target is a rotating target, which improves the overall target utilization rate compared to the plane target. The plane target is sputtered at a uniform speed, which is more stable than the fixed orbit sputtering of the plane target. The gas used to bombard the target is argon, and the target reaction gas is a mixed gas of argon, krypton, nitrogen and oxygen (the volume ratio of argon is 30-60%, nitrogen is 20-35%, oxygen is 5-10%, and krypton is the remainder). The reaction gas is selected as a mixed gas to effectively solve the uniformity of target sputtering and improve the overall optical stability after superposition. After the magnetron coating is completed and aged in an oven, the square resistance can be between 5-10Ω.

[0029] Including but not limited to the following embodiments, the conditions of magnetron sputtering are: acceleration voltage: 300 V, magnetic field: about 80 G, gas pressure: 1 mTorr, current density: 4 mA / cm2, power density: 10 W / cm2.

[0030] Example 1

[0031] The dimming decorative film of the present embodiment includes a PET base material layer, the thickness of the base material layer is 5.7 μm, an upper base coating layer and a lower base coating layer are respectively provided on both sides of the base material layer through a coating process, an upper IM layer and a lower IM layer are respectively provided on the upper base coating layer and the lower base coating layer through a coating process, the upper IM layer and the lower IM layer are both low-refractive acrylic resin coating liquids, the coating thickness of the upper IM layer is 40 nm, and the coating thickness of the lower IM layer is 20 nm, and after coating, a 30 μm high-temperature protective film is attached to the lower base layer to ensure the appearance protection of the film surface and the coating stability during the magnetron sputtering coating process, a primer layer for increasing the adhesion of the base layer is plated on the upper IM layer through a magnetron sputtering process, the thickness of the primer layer is 0.2 nm, and the primer layer can be SiO2 plated, a 1 nm titanium dioxide layer for changing color is plated on the primer layer, a 10 nm silicon dioxide layer for reducing reflection is plated on the titanium dioxide layer, and a 100 nm silicon dioxide layer for increasing conductivity is plated on the silicon dioxide layer. The first indium tin oxide layer (first ITO layer) and the second indium tin oxide layer (second ITO layer) of 100nm need to use different proportions of indium tin targets, otherwise the aging crystallization after film formation will not crystallize. Therefore, indium tin targets with different doping ratios are used for mixed coating, indium tin target ratio (here the first ITO layer is plated with ITO indium accounting for 80%, tin accounting for 20%, and the second ITO layer is plated with ITO indium accounting for 85%, and tin accounting for 15%). The above is dry magnetron vacuum coating sputtering, and the target sputtering can be turned on. The target material is a rotating target, which improves the overall target material utilization rate compared with the plane target, and the plane target is uniformly rotating sputtering, which is more stable than the fixed orbit sputtering of the plane target. The gas for bombarding the target material is argon, and the target reaction gas is a mixed gas of argon, krypton, nitrogen, and oxygen (argon accounts for 30% by volume, nitrogen accounts for 20%, oxygen accounts for 5%, and krypton accounts for the remainder). The reaction gas is selected as a mixed gas to effectively solve the uniformity of target surface sputtering.

[0032] Example 2

[0033] The dimming decorative film of the present embodiment includes a PET substrate layer, the substrate layer has a thickness of 250 μm, an upper primer layer and a lower primer layer are respectively provided on both sides of the substrate layer through a coating process, an upper IM layer and a lower IM layer are respectively provided on the upper primer layer and the lower primer layer through a coating process, the upper IM layer and the lower IM layer are both low-refractive acrylic resin coating liquids, the upper IM layer has a coating thickness of 900 nm, and the lower IM layer has a coating thickness of 900 nm, and after coating, a 188 μm high-temperature protective film is attached to the lower bottom layer to ensure the appearance protection of the film surface and the coating stability during the magnetron sputtering coating process, a primer layer for increasing the adhesion of the bottom layer is plated on the upper IM layer through a magnetron sputtering process, the primer layer has a thickness of 20 nm, and the primer layer can be SiO2 plated, a 30 nm titanium dioxide layer for changing color is plated on the primer layer, a 60 nm silicon dioxide layer for reducing reflection is plated on the titanium dioxide layer, and a 400 nm silicon dioxide layer for increasing the conductivity is plated on the silicon dioxide layer. The first indium tin oxide layer (first ITO layer) of 400 nm and the second indium tin oxide layer (second ITO layer) of 400 nm need to use different proportions of indium tin targets, otherwise the aging crystallization after film formation will not crystallize. Therefore, indium tin targets with different doping ratios are used for mixed coating, indium tin target ratio (here the first ITO layer is plated with ITO indium accounting for 99%, tin accounting for 1%, and the second ITO layer is plated with ITO indium accounting for 98%, and tin accounting for 2%).

The target material is a rotating target, which improves the overall target material utilization rate compared with the plane target, and the plane target is a uniform rotating sputtering, which is more stable than the fixed orbit sputtering of the plane target. The gas for bombarding the target material is argon, and the target reaction gas is a mixed gas of argon, krypton, nitrogen, and oxygen (argon accounts for 60% by volume, nitrogen accounts for 20%, oxygen accounts for 10%, and krypton accounts for the remainder). The reaction gas is selected as a mixed gas to effectively solve the sputtering uniformity of the target surface.

[0034] Comparative Example 1

[0035] The difference between this comparative example and Example 1 is that two ITO layers with the same composition are used: the indium plated ITO accounts for 99% and the tin accounts for 1%.

[0036] Comparative Example 2

[0037] The only difference between this comparative example and Example 1 is that no titanium dioxide layer is plated on the base layer.

[0038] from Figure 1 and 2It can be seen that the unified test method is used. Before the test, the back side is adhered with OCA glue and adhered to a black acrylic plate. After adhesion, a degassing machine is used for degassing. After degassing, the surface is wiped clean and its reflection performance is tested. The average reflection value of 380-780nm is 9.93% for Example 1 and 9.64% for Comparative Example 1, and the difference in the average reflection value is not large. The average transmittance of Example 1 is 82.62%, and the average transmittance of Comparative Example 1 is 82.46%, and the difference in the average transmittance is not large. The a* value of Example 1 is -0.76%, the b* value is -4.2%, and the color is dark blue. The a* value of Comparative Example 1 is -12%, the b* value is 7.5%, and the color is greenish yellow.

[0039] For comparison of square resistance, see Table 1.

[0040]

[0041] As can be seen from Table 1, the unified test method is that after the coating is removed from the machine, the film surface is facing up and placed flat on the table when testing the square resistance. The surface square resistance is tested with a square resistance meter. The film width is 1200mm, and F / C / B is divided into three sections. The square resistance of 10 points BA (before aging) and AA (after oven aging) is evenly tested. The resistance value after crystallization after coating aging is required to be 7.5±2.5Ω. It can be seen from the four batches of samples that the average square resistance of the comparative example AA is as low as 8.3Ω and as high as 8.5Ω; the average square resistance of the embodiment AA is as low as 8.2Ω and as high as 8.3Ω, both of which are within the standard range.

[0042] Warpage comparison, see Table 2.

[0043]

[0044]

[0045] As can be seen from Table 2, the unified test method is to adjust the width after coating, 3 pieces each of F / C / B, specification 340*340mm, heating conditions: 150℃×5min, baking without CPP front protection, with PET back protection, coating side facing up, after baking, wait for the oven temperature to drop below 70℃, take out the sample, and test the warpage degree of the 4 corners of each sample. It can be seen from the above table that the warpage of the new comparative examples is within the standard range.

[0046] The comparison of various environmental tests is shown in Table 3.

[0047]

[0048]

[0049] Table 3 Comparison of various environmental tests of new comparative examples

[0050] As can be seen from Table 3, the unified test method is to stick OCA glue on the back before the ring test and stick it on the transparent glass. After sticking, use a degassing machine to degas. After degassing, wipe the surface clean, test 100℃ water temperature for 1-2h, 100 grids, all 5B; test double 85 ring test (high temperature 85℃, high humidity 85%) for 8-10 days, all 5B; test high temperature ring test (95℃), 8-10 days, all 5B; test low temperature ring test (-40℃), 8-10 days, all 5B; test sunlight resistance ring test (light 0.55w / (m 2 .nm), wavelength 340nm, filter Extended UV-Q / B, 3.8h of light + 1h of dark for 1 cycle, blackboard temperature set at 89℃, box temperature 63℃, humidity 50%; dark stage set box and blackboard temperature 38℃, humidity 95%), 8-10 days, all 5B. The customer requires the environmental test to be OK and qualified after 10 days, so the environmental test performance is OK.
