Abstract
The invention discloses a kind of electroceramics ash glaze reparation glaze composition and preparation method thereof, comprise the raw material of following weight percent: potassium felspar sand 8-16%, quartzy 32-40%, boron oxide 16-24%, water-washed kaoline 6-14%, talcum 4-12%, Wingdale 2-10%, zirconium silicate 2-6%, colorant 4-10%.Colorant comprises: zinc oxide 25-55%, chromic oxide 4-20%, Sodium Fluoride 5-15%, cobalt oxide 30-45%.First by toner raw material through high-temperature calcination, carry out wet ball grinding with parent glaze in the ratio prepared again after levigate, be milled to slip fineness and reach 325 mesh sieves and tail over 0.04-0.06%, namely obtain described electroceramics ash glaze reparation glaze composition.The electroceramics ash glaze reparation glaze composition that this formula is produced, be applicable to various porcelain base substrate, porcelain piece glaze paint is smooth, and color and luster lime is saturating clearly, and surperficial zero defect, improves conforming product rate, meets the need of market.
Description
Technical field
The invention belongs to electroceramics technical field, be specifically related to a kind of electroceramics ash glaze reparation glaze composition and preparation method thereof.
Background technology
Electroceramics goods are in sintering process, the gas that the decomposings such as the organism in base glaze, carbonate, vitriol go out failed fully to discharge before glaze melting, bubble breaks after rising to glaze surface, the pit that can stay can not spontaneous close and form defect, have the shape such as pin hole, circle.In order to these become finished product because glaze plane defect causes not conforming to product, take to repair glaze and carry out secondary clacining to burn till repairing be a kind of practicable method.But currently available technology is to the rare report of electroceramics ash glaze method for repairing and mending.
Summary of the invention
The object of this invention is to provide a kind of electroceramics ash glaze and repair porcelain good mechanical property after glaze, surperficial colouring effect is good, electroceramics ash glaze reparation glaze composition of the defects such as no color differnece and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is: a kind of electroceramics ash glaze reparation glaze composition, described reparation glaze composition comprises the raw material of following weight percent: potassium felspar sand 8-16%, quartz 32-40%, boron oxide 16-24%, water-washed kaoline 6-14%, talcum 4-12%, Wingdale 2-10%, zirconium silicate 2-6%; Colorant 4-10%.
Described colorant is the mixture of zinc oxide, chromic oxide, Sodium Fluoride, cobalt oxide, wherein comprises following weight percent: zinc oxide 25-55%, chromic oxide 4-20%, Sodium Fluoride 5-15%, cobalt oxide 30-45%.
Wherein, potassium felspar sand, quartz, boron oxide, water-washed kaoline, talcum, the mixture of Wingdale and zirconium silicate is called parent glaze.
First the present invention improves from technique, and by each component of colorant in the ratio mixing prepared, through 1100 DEG C of high-temperature calcinations, levigate mistake 325 order, obtains colorant.Again raw material and colorant are carried out wet ball grinding in the ratio prepared, until slip fineness reaches 325 mesh sieves tail over 0.04-0.06%, namely obtain described electroceramics ash glaze reparation glaze composition.Parent glaze firing temperature 1200-1230 DEG C, repairs the firing temperature 950-1050 DEG C of glaze.
Advantage of the present invention is: electroceramics ash glaze reparation glaze composition of the present invention is combined well with ash glaze.Present invention ensures that glaze quality, add yield rate, reduce production cost.Meanwhile, quality is effective, and color and luster lime is saturating clearly, no color differnece, and the outward appearance of electrotechnical porcelain product is greatly improved, and fills up the blank of this type of glaze for electric porcelain, is worth application.
