Abstract

The invention provides glass with self-cleaning, ultraviolet ray resisting and sound-proofing functions and a preparation method of the same. The glass comprises a vacuum sound-proofing layer, transparent baseplates, ultraviolet ray resisting thin film layers and self-cleaning thin film layers, the ultraviolet ray resisting thin film layers and the self-cleaning thin film layers are distributed on the transparent baseplates, and the ultraviolet ray resisting thin film layers are positioned between the glass and the self-cleaning thin film layers respectively. The glass is capable of absorbing light rays at wavelength of 100-350nm by more than 90%, and thereby being capable of preventing ultraviolet rays from injuring skins and causing cancers and achieving a function of air purification. The self-cleaning layers on the surfaces of the glass are ultra-hydrophilic, so that the trouble of cleaning the surfaces of the glass is reduced. The sound-proofing layers have a certain function of proofing various kinds of noises, so that a quite indoor environment can be provided.

Description

【Technical field】 [0001] The invention relates to the field of thin film applications, in particular to a sound-insulating glass with self-cleaning function and anti-ultraviolet rays and a preparation method thereof. 【Background technique】 [0002] As we all know, if a person is exposed to the sun for a long time, the ultraviolet rays will accelerate the aging of the skin, resulting in wrinkles, pigmentation, rough skin or some skin diseases, such as dermatitis, skin cancer and so on. In addition, strong sunlight will also cause aging and fading of some accessories in houses and cars, shortening their service life. However, most of the ordinary glass used in the windows of automobiles, storage rooms, sea view rooms, etc. generally has less functions, poor absorption of ultraviolet rays, poor anti-fouling ability, and is not easy to clean. Moreover, the sound insulation effect is not good, and the room or the car is easily disturbed by external noise. In order to reduce the...
