Problems solved by technology

However, the existing coated glass can only achieve low reflectivity and high transmittance of visible light with a narrow bandwidth, and the coating area is small, so it cannot be mass-produced in large areas.

Embodiment

[0057]A glass for eliminating reflection images, comprising a glass substrate, a functional nano-silica anti-imaging layer coated on the surface of the glass substrate, and an antireflection layer on the silica layer.

[0058]The anti-reflection layer is a titanium dioxide layer or a niobium pentoxide layer.

[0059]The overall transmittance of the glass for eliminating reflection images is greater than or equal to 86%, the haze value is 4 to 5%, and the glossiness is 65°±15°.

[0060]The glass substrate is float glass with a thickness of 2-6 mm, preferably a thickness of 3-4 mm.

[0061]The function nano silicon dioxide layer is obtained by spraying nanosily silica spray liquid to the surface of the glass substrate, wherein the nanosoxide spray liquid is comprised of silica nanowene, bonding, and corresponding auxiliary. The silica has a particle diameter of from 10 to 50 nm, preferably from 30 to 40 nm.

[0062]The penetrating layer is a titanium dioxide layer or a niobium layer obtained by magn...

Abstract

The invention discloses a glass for eliminating reflection images, which comprises a glass substrate, a functional nano-silica shadow-eliminating layer coated on the surface of the glass substrate and an anti-reflection layer on the silicon dioxide layer; the invention is also disclosed Process for the preparation of glass that eliminates reflected images. The beneficial effects of the present invention are: the reflected image can be effectively eliminated, the overall transmittance can be greater than or equal to 86%, the haze value is 4-5%, and the glossiness is 65°±15°; The interference of the virtual image caused by or object reflection to the driver improves the driver's visual environment and can greatly improve driving safety.

Description

Technical field[0001]The invention relates to a glass for eliminating reflection images.Background technique[0002]The front windshield of a car is generally installed obliquely. When meeting a car, the light from the opposite car will shine on the car glass at an angle parallel to the ground. After being reflected by the car glass at a certain angle (usually 40-60 degrees), The light is reflected on the front and top of the car glass and will not be reflected in the eyes of the other driver. However, when driving at night, when the lights are turned on in the car or there is a car behind to illuminate the car, the light from the people and objects in the car will also be reflected in the front view of the driver through the virtual image formed by the front windshield , So that the driver can't distinguish between the person (or scenery) in front and the image of the person in the car, which can easily lead to an accident. Moreover, under strong sunlight on a sunny day, brightly col...
