Problems solved by technology

[0002] The pigments used to decorate patterns and patterns on glassware and glass contain a large amount of lead. Toxic components such as lead are added to glass pigments to improve luster and express rich colors. Therefore, the pollution that occurs during the production of pigments is harmful to the atmosphere. The pollution is very serious, and it is even more harmful to the health of workers on

Abstract

This invention relates to a lead-free glass pigment, which is composed of: lead-free pigment 5-22 wt. % and lead-free flux 78-95 wt. %. The lead-free flux is composed of: SiO2 20-45 wt.%, B2O3 15-35 wt.%, Na2O 1-8 wt.%, K2O 2-10 wt.%, Li2O 1-3 wt.%, Bi2O3 0-9 wt.%, ZnO 1-10 wt.%, TiO2 0-8 wt.%, SnO2 0-6 wt.%, Al2O3 0-10 wt.%, CaO 0-5 wt.%, BaO 0-5 wt.%, CoO 0-11.5 wt.%, ZrO2 0-12 wt.%, and MgO 0-5 wt.%. The lead-free glass pigment is prepared by: preparing the lead-free flux, and then preparing the lead-free pigment. The lead-free glass pigment has such advantages as no toxic or side effects, good color and luster, good decoration effect, and simple preparation method.

Description

technical field [0001] The invention relates to a glass lead-free pigment and a preparation method thereof, belonging to the technical field of glass pigments. Background technique [0002] The pigments used to decorate patterns and patterns on glassware and glass contain a large amount of lead. Toxic components such as lead are added to glass pigments to improve luster and express rich colors. Therefore, the pollution that occurs during the production of pigments is harmful to the atmosphere. The pollution is very serious, and it is even more harmful to the workers on the actual production line. [0003] When the existing lead pigments for glass are printed on glass products, the upper 1.5-2cm of the mouth contact cannot be printed, because the lead component in the pigment dissolves in this part, causing the user to directly contact and absorb the harmful components of lead. It affects people's health, and the mouth that cannot be printed affects the decorative effect. ...
