As shown in fig. 1 to 2, the self-cleaning glass provided by the embodiment of the present invention will now be described. The self-cleaning glass comprises a glass base layer 10, an adhesive layer 20 and a self-cleaning film layer 30, wherein the glass base layer 10 is provided with two opposite end surfaces 13 and an outer peripheral surface 14 which is arranged between the two end surfaces 13 in a surrounding mode, one end surface 13 of the glass base layer 10 is frosted to form a frosted structure 15, the adhesive layer 20 is adhered to the frosted structure 15, and the self-cleaning film layer 30 is coated on the adhesive layer 20.
Compared with the prior art, the self-cleaning glass provided by the embodiment of the invention has the advantages that the frosted structure 15 is arranged on the end face 13 of the glass base layer 10, so that when light irradiates on the glass base layer 10, the frosted structure 15 can diffuse reflection of the light, so that the light is uniformly dispersed at each position of the glass base layer 10 after diffuse reflection of the frosted structure 15 even when the light intensively irradiates on the glass base layer 10, and then irradiates into one side of a user, thereby effectively reducing the occurrence of local dazzling spots on the glass base layer 10, or effectively reducing the brightness of the spots and reducing the stimulation to eyes of the user. Moreover, by arranging the frosted structure 15 on the glass base layer 10, the roughness of the glass base layer 10 on the end face 13 is greatly improved, and the adhesion force of the adhesive layer 20 on the end face 13 of the glass base layer 10 can be effectively improved, so that the adhesive of the self-cleaning film layer 30 on the glass base layer 10 is more stable, and the self-cleaning effect of glass is ensured.
Wherein, the self-cleaning film layer 30 is a nano material with photocatalytic activity, and comprises photocatalyst TiO2 and air catalyst titanium phosphate, wherein the TiO2 can absorb light with a certain wavelength and generate free electrons and holes, so that the pollutants absorbed on the surface of the film are subjected to redox decomposition to remove and kill surface microorganisms, thereby achieving the purpose of self cleaning; and because TiO2 can produce good photocatalytic property under the action of light energy (ultraviolet rays) and has super-hydrophilicity, very small water drops can be converged into large water drops by utilizing the super-hydrophilicity, and the large water drops fall off under the action of gravity, so that stains stained on the large water drops can be easily washed away by water, and the glass has the characteristic of easy cleaning, thereby being particularly suitable for outdoor building glass. The bonding layer 20 is an epoxy acrylic resin layer, has excellent chemical bonding force, has the thickness of 20-25 um, and can bond the self-cleaning film layer 30 and the glass base layer 10 together well.

Wherein, the light-reflecting layer 40 can achieve the effect of partial light reflection by adjusting the light transmittance of the light-reflecting layer 40;
In another embodiment of the present invention, as shown in fig. 1, a plurality of through holes 41 for transmitting light are formed in the reflective layer 40. Specifically, by providing the through holes 41 on the light reflecting layer 40, a part of light can pass through each through hole 41, another part can not pass through the reflection of the light reflecting layer 40, and the light passing through each through hole 41 can be uniformly distributed on the glass base layer 10 under the diffuse reflection of the frosted structure 15, so that no light spot or local dazzling can occur, and the use effect is good.
In another embodiment of the present invention, the light reflecting layer 40 is a blue light reflecting layer 40. Specifically, the blue reflective layer 40 can effectively absorb ultraviolet rays in sunlight to reduce the intensity of ultraviolet rays emitted into a room, thereby achieving good sun protection.
