Abstract
The invention discloses a low softening point lead-free colored glaze, comprising quartz sand, oxidizing agent, clarifying agent, coloring agent and curing agent. The oxidizing agent is zinc oxide. The clarifying agent is ceric oxide. The coloring agent is copper oxide, cobaltous oxide and titanium dioxide. Calculated according to weight percentage, the content of quartz sand is 30%- 40%, the content of zinc oxide is 12%- 20%, the content of ceric oxide is 10%- 15%, the content of copper oxide is 4%- 8%, the content of cobaltous oxide is 4%- -10%. The content of the titanium dioxide is 6%-12%. The content of the curing agent is 10%- 15%. In the above-mentioned manner, the invention adopts zinc oxide instead of lead oxide in the traditional formula, so that the colored glaze formula is lead-free, meeting the environmental requirements and adding a reasonable proportion of titanium dioxide makes the colored glaze with low softening points and long material features.
Description
Technical field
The present invention relates to coloured glaze field, particularly relate to a kind of low softening point lead-free gluzed.
Background technology
Coloured glaze is a kind of silicate product, has a long history, and its quality is glittering and translucent, bright and glittering, changes irregularly magnificent,
Fully demonstrate the exquisiteness of Asians, fine and smooth and implicit, be a kind of important decoration element, coloured glaze be mainly composed of titanium dioxide
Silicon, aluminium oxide, flux lead oxide and pigment etc..
Colored glaze product manufacturing process is complicated, yield rate is low, the molding of colored glaze product and quality in addition to controlling preparation technology,
Depending primarily on the formula components of coloured glaze, coloured glaze composition is low with softening point, a length of good characteristic of material property, and softening point, material property are main
Depending on kind and the proportioning thereof of coloured glaze formula components, existing coloured glaze formula is in order to improve ratio of briquetting and the product of colored glaze product
Matter, is all added with lead oxide in its composition, and along with environmental protection requirement is more come with high by people, various countries have formulated harmful substance
The standard limited, it is stipulated that in glass container, lead Cmax is 0.1%, is therefore the direction of coloured glaze Future Development without lead composition.
Summary of the invention
It is lead-free gluzed that the technical problem that present invention mainly solves is to provide a kind of low softening point, it is possible to solves existing coloured glaze and deposits
Defect.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of unleaded coloured glaze of low softening point
Glass, described coloured glaze includes: quartz sand, oxidant, clarifier, coloring agent and firming agent, and described oxidant is zinc oxide, described clear
Clear agent is ceria, and described coloring agent is copper oxide, cobalt oxide, titanium dioxide, calculates in percentage by weight, described quartz
The content of sand is 30%-40%, and the content of described zinc oxide is 12%-20%, and the content of described ceria is 10%-15%, described
The content of copper oxide is 4%-8%, and the content of described cobalt oxide is 4%-10%, and the content of described titanium dioxide is 6%-12%, described
The content of firming agent is 10%-15%.
In a preferred embodiment of the present invention, the particle size range of described quartz sand is 0.02-0.04mm.
In a preferred embodiment of the present invention, the softening point of described coloured glaze is 380-450 DEG C.
The invention has the beneficial effects as follows: the present invention uses zinc oxide to substitute the lead oxide in conventional formulation, makes this coloured glaze join
Side is the most leaded, meets environmental requirement, and is added with the titanium dioxide of rational proportion, and softening point is low, material property is long to make this coloured glaze have
Feature.
