Problems solved by technology

[0002] The pigments used to decorate patterns and patterns on glassware and tempered glass contain a large amount of lead and cadmium. Adding lead and cadmium to glass pigments is to improve gloss, express rich colors and better chemical stability. Lead Cadmium and cadmium are poisonous heavy metals. If people take lead and cadmium for a long time and accumulate in the human body, it will affect the functions of human hematopoiesis, nerves, kidneys and other organs, and the process of producing pigments is very serious to air pollution, which is harmful to actual production. Frontline workers are at greater risk

Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment.

[0026] All raw materials used in the examples are commercially available unless otherwise specified.

[0027] In the preparation method of the high-corrosion lead-free and cadmium-free tempered glass pigment in the embodiment, the ingredients are prepared according to the composition of the formula, the flux is prepared first, and then the pigment is prepared according to the following steps:

[0028] (1) Preparation of flux: Mix the raw materials required for the purchased flux evenly in proportion, pass through a 80-100 mesh sieve, quench in molten water at 1000-1250°C, and dry for later use;

[0029] (2) Ball milling: the flux and the colorant are mixed and ball-milled until the particle size is less than 5 microns, and the pigment is finished after being dried and pulverized.

[0030] See Table 1 for the weight percent composition of the high-corrosion lead-free and cadmium-free...

Abstract

The invention relates to a pigment flux for tempered glass, in particular to a high-corrosion-resistant lead-free and cadmium-free tempered glass pigment flux. The composition weight percentage of the described flux is: SiO2 10-50%, Bi2O3 1-50%, B2O3 1-20%, Na2O 0.1-5%, SnO2 0.1-2%, Li2O 0.1-3.9%, ZrO2 4.1 ‑16%, Al2O3 2‑5%, CaO 0.1‑6%, ZnO 0‑5%, and MgO 0.1‑6%. The flux described in the present invention has no lead and cadmium toxicity, does not contain fluorine in the formula, is safe and reliable, has good chemical stability, is suitable for black, white, blue, yellow, green and other colorants, has wide adaptability, pure and gorgeous colors, High gloss and good quality.

Description

technical field [0001] The invention relates to a pigment flux for tempered glass, in particular to a high-corrosion-resistant lead-free and cadmium-free tempered glass pigment flux. Background technique [0002] The pigments used to decorate patterns and patterns on glassware and tempered glass contain a large amount of lead and cadmium. Adding lead and cadmium to glass pigments is to improve gloss, express rich colors and better chemical stability. Lead Cadmium and cadmium are poisonous heavy metals. If people take lead and cadmium for a long time and accumulate in the human body, it will affect the functions of human hematopoiesis, nerves, kidneys and other organs, and the process of producing pigments is very serious to air pollution, which is harmful to actual production. Workers on the front line are more physically endangered. [0003] How to avoid the harm of heavy metals such as lead and cadmium, while maintaining the luster and color of the pigment itself, has bec...
