Chinese Patent Publication No. CN104446344B discloses "a preparation method of thin mirror-flat art porcelain plate painting and the product thereof". The product has rich pictures and fine texture, but the product prepared by this method only has a decorative function and does not release negative ions. function, can not play the role of purifying the air
The method is to add indium-containing high-temperature-resistant rare earth composite negative ion functional material powder to the conventional ceramic surface glaze. On the one hand, this addition method seriously affects the negative ion release function because a large amount of negative ion functional materials are distributed in the deep layer of the surface glaze. If the addition of negative ion functional materials is simply increased, the radioactivity index of the product will inevitably exceed the standard, and because the surface glaze is combined with the high temperature resistant rare earth containing indium during the high temperature process. Complex reactions occur, and defects such as pinholes and black spots are prone to appear on the surface of the glaze

Embodiment 2

[0031] Step 1: Provide a ceramic plain plate with a single piece area of ​​1×3.6mm and a thickness of 3.8-4.0mm prepared by firing in a roller kiln at 1250°C;

[0032] Step 2: Percentage by weight: titanium frit 52%, zirconium silicate 15%, calcined kaolin: 4%, alumina 5%, methylcellulose 0.1%, sodium tripolyphosphate 0.3%, ball clay 23.6%; Water 35%, weighed and mixed, added to a ball mill for ball milling, and the fineness of the milled mud is controlled to be 0.05% and the remainder of the million-hole sieve; after sieving and removing iron, make a cosmetic soil bottom glaze slurry with a specific gravity of 1.90-1.95 and a flow rate of 40-45s ;

[0033] Step 3: By weight percentage: potassium feldspar 35%, albite 15%, zirconium silicate 15%, clay 5%, quartz 15%, alumina 5%, zinc oxide 5%, medical stone 4.6%, 0.1% methyl cellulose, 0.3% sodium tripolyphosphate; add 30-35% water, weigh and mix them into a ball mill for ball milling, and control the fineness of the grinding ...

Abstract

The invention discloses a manufacturing method of a ceramic artistic sheet painting capable of continuously releasing negative ions. The manufacturing method comprises the following steps of: firstly applying engobe ground coat on a ceramic plain plate, then applying basic cover coat, then carrying out scientific color separation on a picture file for a production need by color management software in a computer, spraying inorganic pigment and negative-ion high-temperature materials on the surface of the basic cover coat by a modernized high-definition ink-jet printer, and firing at high temperature to obtain the ceramic artistic sheet painting. A ceramic artistic sheet background wall manufactured by the manufacturing method has the advantages that negative ions can be stably and continuously released, so that the quality of indoor air can be effectively improved; and the product can be widely applied to indoor wall decoration of office buildings, houses and the like.

Description

technical field [0001] The invention belongs to the technical field of decorative paintings on ceramic porcelain plates, and in particular relates to a method for making ceramic art thin plate paintings that can continuously release negative ions. Background technique [0002] At present, the production of domestic ceramic porcelain plate paintings is mainly represented by Jingdezhen porcelain plate paintings. Chinese Patent Publication No. CN104446344B discloses "a preparation method of thin mirror-flat art porcelain plate painting and the product thereof". The product has rich pictures and fine texture, but the product prepared by this method only has a decorative function and does not release negative ions. function, can not play the role of purifying the air. [0003] Porcelain plate painting, as an important indoor and outdoor decoration material, can be widely used in public environmental spaces and interior decoration, and is increasingly valued and admired by consum...
