Embodiment 1

[0020] Set the weight percent to 75 SiO 2 15Na 2 The raw material composed of O·9.9CaO·0.1PdO was melted at 1550°C for one hour, cast to form block glass, and then cut and polished. Then use Q-switched 10ns Nd:YAG laser frequency doubled (532nm) to focus and irradiate into the glass to form a pattern. At this time, the naked eye can slightly see the tiny cracks formed by the explosion. After being treated at 600 °C for 1 hour, the pattern turned black.

Embodiment 2

[0022] Set the weight percent to 85 SiO 2 14.89Na 2 The raw material composed of O·0.1ZnO·0.01Pd was melted at 1500°C for 1 hour, cast to form bulk glass, and then cut and polished. Then use the fundamental frequency (1064nm) of the Q-switched 1ps Nd:YAG laser to focus and irradiate it into the glass to form a pattern. At this time, the naked eye can slightly see the tiny cracks formed by the explosion. After being treated at 650°C for 1 hour, the pattern was gray-black.

Embodiment 3

[0024] 45% by weight SiO 2 5B 2 o 3 35CaO 15Na 2 The raw material composed of O·1PdO was melted at 1450°C for 1 hour, cast to form bulk glass, and then cut and polished. Then use a Q-switched 50μS Nd:YAG laser frequency doubled (532nm) to focus and irradiate into the glass to form a pattern. At this time, the naked eye can slightly see the tiny cracks formed by the explosion. Then heat treatment at 560° C. for 1 hour, the pattern becomes black.

Abstract

The invention discloses a kind of glass for interior laser coloration and the formation of three-dimensional black patterns, which comprises the following constituents (by weight percentage): SiO2 45-85, R2O 5-40, RO 5-30, R2O+RO 10-50, R2O3 0-20, Ti02 0-8, Pd 0.001-1, wherein R20 is one or several of Li2O, Na2O and K2O, Ro is one or several of CaO, MgO, BaO, PbO, SrO, ZnO and SnO, R2O3 is one or several of Al2O3, B2O3, Y2O3, La203 and Sb203.

Description

technical field [0001] The present invention relates to glass, in particular to a glass for internal laser coloring and forming a three-dimensional black pattern. Background technique [0002] Laser engraving glass inner engraving handicrafts, the images are exquisite, lifelike, with obvious contrast, strong three-dimensional effect, durable and wear-resistant, and have high technological value. The laser three-dimensional coloring inner carving makes the laser inner carving glass handicraft reach a new level. The inventor mentioned in the previous invention patents that the laser is focused by an optical lens and irradiated with glass, especially glass doped with some special components. When the laser power density exceeds a certain threshold, the focal point of the laser focus in the glass Local coloring effects can occur nearby due to the special multiphoton reaction of the laser with the glass. Generally speaking, the nanosecond-level long-pulse laser produces white b...
