Abstract
The invention discloses lead-free glass with high clarification. The glass comprises quartz sand, fluxing agent, clarifying agent, coloring agent and curing agent. The fluxing agent is potassium nitrate and sodium nitrate. The clarifying agent is barium sulfate. The coloring agent is copper oxide, titanium dioxide and ferric oxide. The lead-free glass is prepared from, by weight percentage, 45%- 55% of quartz sand, 4%- 8% of potassium nitrate, 2%- 7% of sodium nitrate,10%- -15% of barium sulfate, 5%- 10% of copper oxide,10%- 15% of titanium dioxide, 3%- 5% of ferric oxide, and 2%- 5% of curing agent. Through the above way, the method adopts lead-free formula, conforming to requirements of environment protection. The clarifying agent is barium sulfate which replaces expensive ceric oxide. The proportion of raw material ingredients is optimized, to make glass be featured in short clarifying time and low softening point as well as have low cost.
Description
Technical field
The present invention relates to coloured glaze field, particularly relate to a kind of unleaded high clarification coloured glaze.
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
The technical problem that present invention mainly solves is to provide a kind of unleaded high clarification coloured glaze, it is possible to solves existing coloured glaze and exists
Defect.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of unleaded high clarification coloured glaze,
Described coloured glaze includes: quartz sand, flux, clarifier, coloring agent and firming agent, and described flux is potassium nitrate and sodium nitrate,
Described clarifier is barium sulfate, and described coloring agent is copper oxide, titanium dioxide, iron sesquioxide, calculates in percentage by weight,
The content of described quartz sand is 45%-55%, the content of described potassium nitrate is 4%-8%, the content of described sodium nitrate is 2%-7%, institute
The content stating barium sulfate is 10%-15%, the content of described copper oxide is 5%-10%, the content of described titanium dioxide is 10%-15%,
The content of described iron sesquioxide is 3%-5%, the content of described firming agent is 2%-5%.
In a preferred embodiment of the present invention, the particle size range of described quartz sand is 0.02-0.08mm.
In a preferred embodiment of the present invention, the softening point of described coloured glaze is 460-510 DEG C.
In a preferred embodiment of the present invention, the settling time of described coloured glaze is 2-3h.
The invention has the beneficial effects as follows: the present invention uses lead-free recipe, meet environmental requirement, clarifier uses barium sulfate to replace
The ceria that generation is expensive, and optimize the proportioning of each material composition, make this coloured glaze have settling time is short, softening point is low spy
Point, simultaneously low cost.
Detailed description of the invention
