Description

Technical Field

[0001] The present invention relates to the technical field of color crystal glass preparation, and particularly to a production process of natural diffused light based on color micro-patterning of color crystal glass. Background Art

[0002] Color crystal glass is a new type of decorative material, which is prepared by printing a colored coating with ink or a colored transparent coating of ink on the surface of the glass and then coating a bottom sealing protective layer; as people's requirements for the quality and appearance of glass materials are getting higher and higher, color crystal glass, as a high-quality and high-appearance decorative glass material, is being continuously improved and innovated.

[0003] By using a transparent glass sheet and printing dot patterns (i.e., light guide points) on the bottom surface of the sheet with light guide ink, the light can be absorbed and then emitted. Using this property, the propagation direction of the light can be changed, so that the light no longer satisfies the total reflection condition and is emitted from the light guide plate. By using the sheet to absorb the light emitted from the light source and stay on the surface of the sheet, when the light irradiates each light guide point, the reflected light will diffuse in all directions, and then the reflection condition is destroyed and emitted from the front of the light guide plate. It mainly makes the light emit evenly through various light guide points with different densities and sizes, forming different optical aesthetics; however, the light scattering effect of the light guide powder in the existing light guide ink is poor, and its optical performance needs to be further improved; on the other hand, with the continuous development of the glass industry, the production process of glass coatings is basically finalized in screen printing, with few subsequent changes and a single process form.
