Description

Technical Field

[0001] The present invention relates to the technical field of colored crystal glass preparation, and in particular to a production process of natural diffuse reflection light based on colored crystal glass colored micro-patterning. Background Art

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

[0003] By using transparent glass plates and printing dot patterns (i.e., light guide points) on the bottom of the plates with light guide ink, light can be absorbed and then emitted. This property can be used to change the propagation direction of light, so that the light no longer meets the total reflection condition and is emitted from the light guide plate. The plate is used to absorb the light emitted from the light source and stay on the surface of the plate. When the light shines on each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. It mainly emits light evenly through various light guide points of different densities and sizes, forming different optical aesthetics. However, the light guide powder in the existing light guide ink has a poor light scattering effect on light, and its optical performance needs to be further improved. On the other hand, with the continuous development of the glass industry, the glass coating production process is basically finalized on screen printing, with few subsequent changes and a single process form.
