A kind of ceramic glaze and preparation method thereof with metal-like, with the pottery of its manufacturing
Technical field
The present invention relates to pottery, glass enamel material technical field, refer to a kind of ceramic glaze especially with metal-like.
Background technology
Pottery be by clay or based on the mixture of clay, feldspar, quartz etc. through moulding, drying, fire the goods that form.Traditional pottery often has characteristics such as color and luster is low and deep, opaque, suction owing to do not do any surface treatment, and the color of pottery is subjected to the kind restriction of the metal ingredient in the mineral substance and limits to.For color that enriches pottery and the physical and chemical performance that improves pottery, people more and more pay attention to the research of bristol glaze.
For this reason, people develop various glaze with difference in functionality, as luminous class glaze, application number: 99123083, the applying date: on December 15th, 1999, denomination of invention: luminescent glaze, this light-accumulating luminescent glaze is made up of different kinds of ions activated long after glow luminous material and base solvent, luminescent ceramic, luminescent enamel and fluorescent glass goods with this luminescent glaze manufacturing have illumination effect, but lack metallic character and texture.
Therefore, demand providing a kind of glaze that is used to be coated on ceramic surface urgently,, and make it have certain metal-like with the mechanical property and the chemical stability on the surface of further enhancing ceramic.
Summary of the invention
Based on the deficiencies in the prior art, main purpose of the present invention has been to provide a kind of glaze that can further strengthen the physical and chemical performance of ceramic, makes it have the glaze of certain metal-like and characteristic.
A kind of ceramic glaze of the present invention with metal-like, it contains at least a metal oxide, is made up of underlying metal cover-coat enamel and covering screen printing glaze, and it comprises following component, and weight percent content is as follows:

A kind of manufacture method with ceramic glaze of metal-like may further comprise the steps:
(1) at first, choose suitable proportion raw material according to required color;
(2) secondly, adopt micro mist equipment respectively above-mentioned raw materials to be carried out grinding and processing, the size of the pellet after the control processing is no more than 400 orders;
(3) the various raw materials after will pulverizing are according to should needing the proportioning uniform mixing and carry out siccative and handle, and the siccative process is controlled at 1000-1250 ℃ with temperature range;
(4) last, put it into ball mill and add water and grind and make the underlying metal glaze respectively and cover screen printing glaze, the size range of control glaze grain is 0.8-1g/325 eye mesh screen/100ml, and proportion is 1.25-1.5g/ml, and glazing heavily is 90-260g/60 * 60cm
2
In step (4), the Xylo-Mucine (CMC) that also can add 0.5-1% carries out ball milling, to increase the viscosity of glaze.
Compared with prior art, ceramic glaze of the present invention sprayed on the work in-process of pottery, fire the ceramic that forms again, because this kind glaze contains various metal oxides, make the ceramic product that is prepared from not only present various metallic luster, the surface has certain metal-like, and, improved its physical and chemical performance greatly, mechanical propertys such as physical strength and fastness to rubbing have been improved, make product not only attractive in appearance but also durable in use, fill up the blank of ceramic decoration field metal glaze, promoted the development of the ceramic of colorful metal glaze.In addition, comparatively simple on the preparation technology of glaze and glazing process, easy control of process conditions is fit to large-scale technology production.
For making the present invention easier to understand, further set forth a kind of specific embodiment of the present invention with ceramic glaze of metal-like below in conjunction with accompanying drawing.
Embodiment
Below further set forth a kind of prescription of the present invention with ceramic glaze of metal-like.
Glaze of the present invention is by the underlying metal cover-coat enamel and cover screen printing glaze and forms, its be mineral substance by containing various metal ingredients such as phosphorus, calcium, strontium, zinc, lead as raw material, or the following compound of employing carries out mixing match according to different deals and makes respectively.According to the underlying metal cover-coat enamel of allotment with cover the different of metal content in the screen printing glaze, present different metallic luster, as cuprous look, highlighted iron look, orichalceous, gold look, inferior light platinum look etc., can trace adding 1% chromic oxide (Cr).Following table illustrates the underlying metal cover-coat enamel when presenting the different metal color and luster by several embodiment and covers the different proportionings of screen printing glaze.

Below sketch a kind of manufacture method of the present invention with ceramic glaze of metal-like:
(1) at first, choose suitable proportion raw material according to required color;
(2) secondly, adopt micro mist equipment respectively above-mentioned raw materials to be carried out grinding and processing, the size of the pellet after the control processing is no more than 400 orders;
(3) the various raw materials after will pulverizing are according to should needing the proportioning uniform mixing and carry out siccative and handle, and the siccative process is controlled at 1000-1250 ℃ with temperature range;
(4) last, put it into ball mill and add water and grind and make the underlying metal glaze respectively and cover screen printing glaze, the size range of control glaze grain is 0.8-1g/325 eye mesh screen/100ml, and proportion is 1.25-1.5g/ml, and glazing heavily is 90-260g/60 * 60cm
2
In step (4), the Xylo-Mucine (CMC) that also can add 0.5-1% carries out ball milling, to increase the viscosity of glaze.
During use, underlying metal cover-coat enamel and the covering screen printing glaze of making successively sprayed on the surface of ceramic semi-finished product equably, after vegetarian noodles or printing treatment, directly advance klining and become to get final product.
The not only color variation of ceramic after the glazing, glaze quality is good, and mechanical property and chemical stability are all had been further upgraded, and general glaze fastness to rubbing is greater than 2.5cc, if after adding wear-resisting ceramic glaze printing, fastness to rubbing can be promoted to more than the 3.5cc, has improved the mechanical property of ceramic greatly, meets the paving requirement in popular place, simultaneously, the acid and alkali-resistance degree also reaches the A grade standard after testing, and the corrosion resistance excellence is suitable for the laying of exterior wall.
Five colours metal glaze only need be sprayed onto the ornamental brick surface through burning till with the glaze spraying cabinet, just can obtain glistening metal effect, just as glistening sandy beach under the setting sun, be sprayed on brick face modelled after an antique, just like placing oneself in the midst of among the nature, true to nature, naturally reach back to nature, return Piao and return genuine effect, and every tile only needs a little to get final product, and because of it is series product, can only use on brick modelled after an antique in the past, use on can changeing in micro mist, polishing now, changeing on exterior wall, square again, have wide range of applications.
Above disclosed only is a kind of preferred embodiment with ceramic glaze of metal-like of the present invention, certainly can not limit the present invention's interest field with this, therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
