Abstract

The invention provides a preparation method of relief glaze and belongs to the technical field of preparation of ceramic crafts. The preparation method of the relief glaze disclosed by the invention comprises the following steps: (1) pulverizing 38-42% percentage by weight of potassium feldspar, 26-30% percentage by weight of marble, 10-15% percentage by weight of talc, 3-5% percentage by weight of kaolin, 6-10% percentage by weight of clay and 6-18% percentage by weight of calcium phosphate and sieving with a 260-mesh sieve; and (2) evenly stirring power of raw materials, pouring into a ball-milling container, adding equal weight of water into the raw materials at the ratio of 1:1, sealing the container by a cover and carrying out ball-milling for 50 hours. By applying a certain thickness of the relief glaze, which is prepared by the preparation method of the relief glaze disclosed by the invention, on a ceramic green body or a biscuit firing billet, cracks are generated due to the shrinkage cracking during the drying, the glaze is vitrified by virtue of glaze firing to enable the glaze to have an appropriate flowability by controlling the temperature, the surface tension of the glaze breaks at the crack and the glaze respectively aggregates into droplets and thus a naturally raised relief effect is generated.

Description

The compound method of embossment glaze

Technical field

The invention belongs to ceramics manufacture technology field, particularly relate to a kind of compound method of embossment glaze.

Background technology

Make ceramic surface form concavo-convex clearly demarcated embossment and have cubic appearance, traditional method be adopt engraving, the means such as landfill or transfer printing on biscuit of ceramics people for forming.But the effect produced like this is very undesirable---it is thicker that depressed area amasss glaze, and concavo-convex not obvious, corner angle are fuzzy, lacks stereoscopic sensation, moreover complex process, cost intensive.

In Production of Ceramics practice, because some process operations is improper, glaze firing product generally can be caused to occur local or big area contracting glaze, thus have a strong impact on quality product and economic benefit.But this exactly " bad phenomenon " but gives us one and gathers in the crops unexpectedly.

Summary of the invention

The invention provides a kind of compound method of embossment glaze, the inventive method is simple, and the anaglyph of generation is fairly obvious, and the lines flow smoothly for it, clean mark, the smooth exquisiteness of glaze paint, rich very strong sight and suitability.

The compound method of embossment glaze of the present invention, comprises the following steps:

(1) be 38-42% potassium felspar sand, 26-30% marble, 10-15% talcum, 3-5% kaolin, 6-10% clay and 6-18% calcium phosphate by weight percent, pulverize after 260 mesh sieves;

(2) after above-mentioned raw materials powder being stirred, pour in ball mill container, add the weight water such as 1:1, seal, ball milling 50 hours.

By on ceramic green or biscuit; execute certain thickness employing embossment glaze of the present invention compound method and obtain embossment glaze; slight crack is produced owing to shrinking dry and cracked in drying process; glaze vitreous is made through glaze firing; control temperature makes glaze have adequate liquidity; glaze its own face tension force is also gathered into separately in cracks disjunction and drips, thus produces natural raised emboss effect.

Embodiment

Below by specific embodiment, the present invention is further illustrated.

The system of embossment glaze is joined

Required ore and degree thereof:

Potassium felspar sand 38-42%

Marble 26-30%

Talcum 10-15%

Kaolin 3-5%

Clay 6-10%

Calcium phosphate 6-18%

By the raw ore of formula composition aequum, through pulverizing after 260 mesh sieves, pour into after stirring in ball mill container, add the weight clean waters such as 1:1, seal, ball milling 50 hours, namely gained glaze slip is " embossment glaze ".

First, ceramic green or biscuit are cleaned out, suitable moisturizing;

Secondly, common transparent or color glaze is imposed at position such as the vessel porcelain inwall not wanting glaze paint formation embossment;

Again, traditional transfer printing printing technology is used to form multicoloured pattern in the region of necessity, decorative pattern and personage birds and beasts.

Finally, need formed position or region as the appearance wall of vessel porcelain, the outer edge of flat porcelain adopts spraying, brush or soak, dip mode glazing, after dry, glazed thickness preferably ensures 0.6-0.8mm, uniform smooth, to produce a large amount of crackle because of dry and cracked in drying process, glaze layer is become countless fritter by crack segmentation, forms the blank of embossment.

Artistic decoration: add the ceramic glaze that common ceramic pigment sill just can form shades of colour in natural relief glaze, or add the color base material that following composition and proportioning form and also can reach effect like this.

By zirconium silicate 52-72%, cobalt chloride 9-29%, chromoxide green 2-10%(weight percent) form black color base material, add natural relief glaze with the ratio of 5.3:100, " embossment " that burn till rear goods is black.

By red iron oxide 6-26%, chlorination chrome green 4-24%, zinc oxide 39-59%, aluminum oxide 10-30%(weight percent) form brown color base material, the ratio added with the ratio of 1.96:100 adds natural relief glaze, and " embossment " that burn till rear goods is brown.

By red iron oxide, zircon, Cadmium oxide, potassiumchromate, stannic oxide, the red color base material that magnesium oxide and dispersion agent are formed, add natural relief glaze with the ratio of 2-6:100, the goods " embossment " after burning till are redness.

By V 2 O, zirconium white, cobalt oxide, the blue color base material that zinc oxide is formed, with 2-6:100(weight ratio) ratio add natural relief glaze, " embossment " that burn till rear goods is for blue.

In addition, can also coated ceramic industry is conventional on ceramic green or biscuit color paint, then impose the embossment glaze paint that embossment glaze just can be formed with color background.Also can by the glaze layer of color base material spraying after glazing, the coloured block-shaped protrusion embossment of same formation after glaze firing.

Goods burn till: after glazing process completes, and adopt oxidation to burn till.First should arrange film at 850-900 ° of C temperature as goods post marble paper, to be more progressively warming up to 1210 ° of C(optimum tempss should be 1190-1220 ° of C), soaking time 5-10 minute, then flame-out cooling.The ceramic glaze paint of such gained will self-assembling formation clearly concavo-convex, the relief shape that sensation is fine and smooth.

Certainly, it should be noted that best temperature of glaze firing slightly must change because the change of ceramic glaze composition, in a word should higher than the vitrification point of ceramic glaze, but time as too high in temperature, the viscosity of ceramic glaze is too little, and mobility is excessive and affect anaglyph.

The method that Ceramic glaze is formed natural relief melts tradition and modernity Ceramic glaze decoration technology in one, organically scientifically have updated manual carve with the result of physical and chemical reaction.It has not only saved production cost greatly, enhance productivity, more importantly can obtain artificial can not and special-effect, and be widely used in domestic ceramics, the production field such as art ceramics and construction sanitary ceramic, the particularly application of art ceramics, can adapt to both at home and abroad, the demand of particularly European & American Market.The Guangzhou Export Commodities Fair is subject to the favor of a lot of client, for enterprise creates benefit.
