Problems solved by technology

[0004] Traditional semi-reflective and semi-transparent optical films are coated on PET flexible substrates and then pasted on the cover glass of mobile phones and tablet computers. However, the PET film layer has a certain amount of light absorption. When using mobile phones and tablet computers, the backlight needs to be brighter. Operation, the visual effect is poor

preparation example Construction

[0049] Such as figure 2 The preparation method of the above-mentioned transflective and translucent glass shown comprises the steps:

[0050] S10, providing the glass substrate 10, washing and drying.

[0051] The glass substrate 10 can be selected from float glass or other conventional glass in the field.

[0052] S20, deposit the first low refractive index layer 20, the first high refractive index layer 30, the second low refractive index layer 40, the second high refractive index layer 50, the third The low refractive index layer 60 and the ITO layer 70 are used to obtain a semi-reflective and semi-transparent glass.

[0053] The material of the first low refractive index layer 20 is SiO 2 or MgF 2 . SiO 2 The refractive index of 1.48, MgF 2 The refractive index of 1.38. Using SiO 2 or MgF 2 As the material of the first low refractive index layer 20 , the transmittance of the first low refractive index layer 20 is relatively high.

[0054] The thickness of the f...

Embodiment 1

[0069] The float glass is washed and dried.

[0070] The working pressure is 2×10 -3 Under the condition of mbar, on the surface of float glass, the thickness is sequentially deposited as SiO 2 layer, thickness is Nb 2 o 5 layer, thickness is SiO 2 layer, thickness is Nb 2 o 5 layers and thicknesses are SiO 2 layer to obtain the required transflective and semi-transparent glass with a reflectivity of 20%.

Embodiment 2

[0072] The float glass is washed and dried.

[0073] The working pressure is 3×10 -3 Under the condition of mbar, on the surface of float glass, the thickness is sequentially deposited as SiO 2 layer, thickness is Nb 2 o 5 layer, thickness is SiO 2 layer, thickness is Nb2 o 5 layers and thicknesses are SiO 2 layer to obtain a transflective glass with a reflectivity of 33%.

Abstract

The invention discloses a semi reflective and semi transparent glass. The reflectivity of the glass is 20-50%. The glass comprises a glass substrate, a first low refractivity layer, a first high refractivity layer, a second low refractivity layer, a second high refractivity layer and a third low refractivity layer which are piled up layer by layer, wherein the first, second and third low refractivity layers are made of SiO2 or MgF2 and the first and second high refractivity layers are made of Nb2O5, TiO2 or ZrO2. By virtue of a film layer structure of suitable thickness combining layers of high and low refractivity, the semi reflective and semi transparent glass has semi reflective and semi transparent performances and the optic visual effect of semi reflective and semi transparent is realized during use; meanwhile, the semi reflective and semi transparent glass has advantages in durability and wear resistance compared to a semi reflective and semi transparent auto foil. The invention further discloses a preparation method of the semi reflective and semi transparent glass.

Description

technical field [0001] The invention relates to a semi-reflective and semi-transparent glass and a preparation method thereof. Background technique [0002] Existing smart touch electronic products such as tablet computers and touch-screen mobile phones often need to be pasted with a semi-reflective and semi-transparent optical film on the surface to achieve semi-reflective and semi-transparent optical performance, which can play a mirror reflection when the smart touch product is in standby Effect, can be used as a mirror to organize makeup, or comb hair. There is also a semi-reflective and semi-transparent optical film on the back cover glass, so that the front cover can display and touch normally, and the back cover has a certain degree of specular reflection. [0003] There are also some cars that use semi-reflective and semi-transparent optical film as the interior rearview mirror of the vehicle, so that the traffic conditions behind can be clearly observed, and it can...
