Description

N5

CO The invention relates to the printing of certain types of products, mainly decal, and may find application in the manufacture of ceramic decals for underglaze decoration of porcelain and fancy products. Known underglaze paint based on cobalt oxide, including, by weight.h. CojO 44.6; alumina 55.4 l. This paint does not bake with a crock and is unstable when glazed. Closest to the one proposed is underglaze decorating paint, comprising the following components, wt%:, 46.7; Te2 7.64; , 0.14; BgO; 0.83; 1.3, - KgO 0.75, - MRO 0.24; CaO 0.82 / Si02 40.24, -Ti02 0.12; SrO 0.12 2. However, the known ink cannot be used to print underglaze decals transferred to a wet shard. The purpose of the invention is to ensure the transfer of decal to a raw shard. The goal is achieved by those that underglaze paint, mainly for ceramic decal, including Co-0. ,,,,, K20, RgO, CaO, SiO, j .TiO, DO completely contains PCO in the following ratio of components, wt.%:, 67-32.24 At, 0.3.74-4.89; 0.022-0.033 6.06 -9.27, 11-1.45 0.13-0.14 0.83-0.93, 033-0.037 PbO20.94-32.05 Raw materials are used, wt.%: Cobalt oxide 22.5 -30.0; ground quartz 14.3-15.8 feldspar 8.2-11.0; Kaolin 1.11, 4; porcelain skull 5,9-7,9; dolomite 3.0-3.9; red lead 20,030, 0; bornna acid 10.0-15.0. The paint is prepared as follows. Initially melt flux for paint, c. the composition of which consists of red lead, quartz and bourne acid. The flux mixture is prepared by dry mixing the pre-weighed components in a cone mixer for 40-60 minutes until a homogeneous mixture is formed. The mixture is melted in a rotating PV-300 furnace at 900-950С and poured into granulation into water, after which the flux is dried at 70-80 s. Underglaze paint components: cobalt oxide, ground quartz, feldspar, kaolin, porcelain skull, dolomite and flux weighted according to the recipe are loaded into a ball mill for grinding. The weight ratio of crushed χ materials of balls and water is 1: 1.3: 0.5. Grinding is carried out to the residue on the sieve with the mesh No. 0056 (10858 holes / cm) not more than 0.3%. After grinding, the paint dries in vapor-gas or electric dryers at 70-80 s to a moisture content of not more than 0.3%. The dried dye is sifted through a sieve with a mesh S 0315 (445 sp / cm). Printing underglaze ceramic decal is produced by the specified ink according to known technology.

E 1070123.

The proposed paint can be applied. All compositions are characterized for printing of a subglare decal, the lack of abrasion when the mechanic is converted to a molded effect on the burned

dry product (raw shard) and a shard with a decal at 760-7 (.

Le firing is fixed on it. The economic effect of ispolzol zata and glazed with water suspension-5 vani underglaze paint will be

her glaze. 0,017 p and unit products.
