Problems solved by technology

And according to different color and color requirements, the above ingredients and proportions need to be adjusted accordingly, so in the manufacturing process, it will undoubtedly increase the workload and increase the cost
Secondly, although the above-mentioned lead-free pigments do not contain lead, their glossiness is far lower than that of leaded pigments, and their glossiness is about 70-80 degrees, while the glossiness of normal lead pigments is above 80 degrees. The effect also has a large image, resulting in dull patterns, no appearance, and not strong acid and alkali resistance

Embodiment 1

[0021] Embodiment 1: chrome green lead-free pigment

[0022] Components: It consists of 10% chrome green lead-free toner and 90% lead-free flux, wherein the weight percentage of flux is composed of: SiO 2 47.8%, B 2 o 3 17.7%, Al 2 o 3 0.5%, Li 2 O4.1%, Na 2 O5.7%, K 2 O2.6%, BaF 2 2.8%, P 2 o 5 2.6%, Ta 2 o 3 0.5%, Nb 2 o 5 0.5%, ZrO 2 0.5%, CeO 2 1%, La 2 o 3 0.5%, Y 2 o 3 0.5%, ZnO12.2%, MgO0.5%.

[0023] Preparation method: Mix the raw materials of the solvent components passed through 40-80 mesh sieves, melt at high temperature, quench in cold water, dry and pulverize to above 100 mesh for later use; mix lead-free solvent and lead-free toner, and pass through airflow Pulverize to obtain chrome green lead-free pigment.

Embodiment 2

[0024] Embodiment 2: white lead-free pigment

[0025] The flux component content and preparation method are the same as those in Example 1, except that the white lead-free pigment consists of 15% white lead-free toner and 85% lead-free flux.

Embodiment 3

[0026] Embodiment 3: golden red lead-free pigment

[0027] The flux component content and preparation method are the same as those in Example 1, except that the golden red lead-free pigment is composed of 5% golden red lead-free toner and 85% lead-free flux.

Abstract

The invention discloses a glass lead-free pigment comprising a 5-20% of lead-free toner and an 80-95% of lead-free flux by a weight percentage, wherein the weight percentage composition of the flux is as follows: SiO2 46-49%, B2O3 15-20%, Al2O3 0.1-1%, Li2O5 2-3.5%, Ta2O3 0-0.5%, Nb2O5 0-1%, ZrO2 0-0.5%, CeO2 0-2%, La2O3 0-0.5%, Y2O3 0-1%, ZnO 8-13%, MgO 0-0.5%. The invention also discloses a preparation method of the lead-free glass pigment. The glass lead-free pigment of the invention has advantages of compact structure, antiacid-alkali erosion, good chemical stability, low fired temperature and high glossiness and the like.

Description

technical field [0001] The invention relates to a glass pigment and a preparation method thereof, in particular to a glass lead-free pigment and a preparation method thereof. Background technique [0002] The pigments used for decorative patterns on glass products usually contain a large amount of lead. The purpose of adding lead to glass pigments is to improve gloss and express rich colors. Lead is very serious for environmental pollution and is also toxic to the human body. It will deposit in the human body and is not easy to metabolize. The harm of lead poisoning is mainly manifested in lifelong damage to the nervous system, blood system, cardiovascular system, and bone system. harm. Therefore, the development of glass lead-free pigments has become the focus of research in recent years. [0003] At present, the glass lead-free pigment researched and developed by Zibo Huawei Pigment Co., Ltd. and its preparation method (public number: CN101050061A), the lead-free pigment...
