It is used to make the one-way anti-glare heat insulation film 3 have basic support, so as to facilitate the use and operation of the one-way anti-glare heat insulation film 3, and does not affect the one-way anti-glare heat insulation film 3 basic optical properties.

該光學調整層35用於調整光穿透率至介於40~70%之間,以便於控制入射光線及出射光線的光入射及穿透量。該光學調整層35為利用染料進行光線吸收,可利用塗佈等方式形成於該支撐層34上,並可視需求透過製程控制而令該光學調整層35為具有至少兩種光穿透度變化的漸變光學膜,或是具有單一光穿透率的全版膜。The optical adjustment layer 35 is used to adjust the light transmittance to between 40% and 70%, so as to control the light incidence and penetration of the incident light and the exit light.

When applied to the door and window glass of a car, the optical adjustment layer 35 with a single light transmittance can be used, so that the one-way anti-glare heat insulation film 3 can be more widely used.

此外,透過該光學單元32對外界入射光的高反射性以及內部光線高穿透的特性,讓該單向透視抗強光隔熱膜3的兩相反側具有不同的光穿透率,還可令該單向透視抗強光隔熱膜3具有單向透視的特性。特別是夜間使用時,可令車內/室內光線具有高穿透性,可不影響夜間視線,並對外部入射光線具有高反射性,無法清楚自外界觀測內部,而可具有更佳的隱蔽性。In addition, the high reflectivity of the optical unit 32 to the external incident light and the high penetration of the internal light allow the two opposite sides of the one-way anti-glare heat insulation film 3 to have different light transmittances.

Especially when used at night, it can make the car interior/indoor light have high penetrability, does not affect the night vision, and has high reflectivity to the external incident light. It cannot clearly observe the interior from the outside, and can have better concealment.

前述該光學調整層35所用的染料種類為相關技術領域者所週知且非為本發明之重點,因此,於此不多加說明。The aforementioned dyes used in the optical adjustment layer 35 are well-known to those in the related art and are not the focus of the present invention. Therefore, no further description is given here.

該強化層36由硬度大於F(鉛筆硬度測試)且透光度不小於90%的無機材料構成,可用於保護該光學調整層35不易受到損壞。於一些實施例中,該強化層36選自氧化鋯為構成材料。The strengthening layer 36 is made of an inorganic material with a hardness greater than F (pencil hardness test) and a light transmittance of not less than 90%, and can be used to protect the optical adjustment layer 35 from being damaged. In some embodiments, the strengthening layer 36 is selected from zirconia as a constituent material.

前述該單向透視抗強光隔熱膜3的製作是以該支撐層34為基礎,分別在該支撐層34的相對兩側,利用塗佈方式各自形成該光學調整層35、該強化層36,以及該底塗單元33,之後再利用低溫濺鍍方式於該底塗單元33上形成依序交錯堆疊的該光學單元32,最後再於該光學單元32表面形成該透明光學膠層31,即可製得該單向透視抗強光隔熱膜3。之後,將該單向透視抗強光隔熱膜3貼合在該玻璃基材2的內表面21,即可得到該單向透視抗強光隔熱玻璃。The aforementioned one-way perspective anti-glare heat insulation film 3 is made on the basis of the support layer 34, and the optical adjustment layer 35 and the strengthening layer 36 are respectively formed on opposite sides of the support layer 34 by coating. , And the primer unit 33, and then use a low-temperature sputtering method to form the optical units 32 stacked sequentially and staggered on the primer unit 33, and finally form the transparent optical adhesive layer 31 on the surface of the optical unit 32, namely The one-way anti-glare heat insulation film 3 can be produced. After that, the one-way anti-glare heat-insulating film 3 is attached to the inner surface 21 of the glass substrate 2 to obtain the one-way anti-glare heat-insulating glass.

參閱圖2,要說明的是,前述該單向透視抗強光隔熱膜3於貼合在該玻璃基材2前,於該透明光學膠層31反向該光學單元32的表面可先覆蓋一層可撕離地移除的離型層37。利用該離型層37隔離保護該透明光學膠層31,並可於使用時將該離型層37撕除即可利用該透明光學膠層31與該基材2的內表面21貼合,而得到該單向透視抗強光隔熱玻璃。Referring to FIG. 2, it should be noted that, before the one-way anti-glare heat insulation film 3 is attached to the glass substrate 2, the surface of the optical unit 32 opposite to the transparent optical adhesive layer 31 may be covered first A release layer 37 that can be detachably removed. The release layer 37 is used to isolate and protect the transparent optical adhesive layer 31, and the release layer 37 can be torn off during use, and the transparent optical adhesive layer 31 can be used to adhere to the inner surface 21 of the substrate 2, and The one-way perspective anti-glare heat-insulating glass is obtained.

此外,要再說明的是,前述該單向透視抗強光隔熱玻璃,其所需要的光學性質在不同場所會有不同要求,可藉由調整該單向透視抗強光隔熱膜3而得。例如,當該單向透視抗強光隔熱玻璃是一般建築的玻璃門窗時,該單向透視抗強光隔熱膜3的霧度僅需控制在不大於3%即可。而若該單向透視抗強光隔熱玻璃是車輛的擋風玻璃時,該單向透視抗強光隔熱膜3的霧度則需控制在不大於1%,以同時滿足車輛安全的規範。In addition, it should be further explained that the required optical properties of the aforementioned one-way anti-glare heat-insulating glass have different requirements in different places, and the one-way anti-glare heat-insulating film 3 can be adjusted. Got. For example, when the one-way anti-glare heat insulation glass is a glass door and window of a general building, the haze of the one-way anti-glare heat insulation film 3 only needs to be controlled to be not more than 3%. If the one-way anti-glare heat-insulating glass is the windshield of a vehicle, the haze of the one-way anti-glare heat-insulating film 3 needs to be controlled to not more than 1% to meet the vehicle safety regulations at the same time. .
