Problems solved by technology

However, the color printing of the pad printing machine uses color materials, and then glazes after painting. What is reflected on the ceramics is a flat pattern, and the glaze layer only acts as a protective layer; and the gloss of the color materials is poor, failing to achieve the color. decorative effect of glaze

Embodiment 1

[0029] A preparation method for glaze isolation printing color ceramics, comprising the following production steps:

[0030] (1) Preparation of basic glaze powder: 26 parts by weight of potassium feldspar, 30 parts by weight of quartz, 11 parts by weight of kaolin, 17 parts by weight of calcite, 8 parts by weight of calcined talc, 6 parts by weight of zirconium silicate, and 2 parts by weight of zinc oxide were selected as The basic glaze powder raw materials are mixed and then added with water for wet ball milling. The ball milled raw materials are iron-removed through an iron remover, passed through a 320-mesh sieve, and then filtered to remove water and then dried to prepare the basic glaze powder;

[0031] (2) Surface layer glaze preparation: Take 90 parts by weight of the basic glaze powder prepared in step (1) and 10 parts by weight of the color base material as raw materials for the surface layer glaze, add water after mixing, carry out wet ball milling, pass through a 3...

Embodiment 2

[0039] According to the preparation method of the technology of the present invention, specially carried out comparative test, the results are as follows:

[0040] (1) The difference from the example is that no release agent is added to the bottom glaze, and the printed pattern lines do not have water repellency, resulting in unclear pattern lines on the glazed surface of the product after firing, and the glazed surface of the product does not have water repellency. artistic effect.

[0041] (2) The difference from the examples is that bentonite is not added to the bottom glaze, and the printed lines are not neat and broken.

[0042] (3) The difference from the example is that the residence time of the product in the glaze liquid is 2 seconds during the dipping, and the thickness of the absorbed glaze layer of the dipped product is insufficient, which reduces the artistic effect of the glazed surface of the product after firing.

[0043] (4) The difference from the examples i...

Abstract

The invention relates to a preparation method of glaze isolated color-printed chinaware, which belongs to the technical field of ceramic preparation. The preparation method comprises the following steps: preparing basic glaze powder, surface layer glaze, bottom layer glaze and a chinaware clay body, performing color printing on the surface of the mud clay body by using a transfer color printing machine conventionally used by ceramics for daily use and using the bottom layer glaze to obtain a pattern composed of strips, drying, manually glazing the color-printed and oven-dried product, storing the glazed product in a cool and dry place for 8-16 hours, and burning the glazed product in a kiln to obtain the glaze isolated color-printed chinaware. The product prepared by using the preparation method of the invention has a slightly concaved-convexed and colored pattern on the surface thereof, and has a good three-dimensional effect; the glaze isolated color-printed chinaware has regular appearance and smooth glaze, and the strip-like motif pattern in the glaze is clear; and the method has high efficiency and low cost.

Description

technical field [0001] The invention relates to a method for preparing colored ceramics, in particular to a method for preparing high-quality and inexpensive glaze-isolated and printed colored ceramics, and belongs to the technical field of ceramic preparation. Background technique [0002] There are many varieties of ceramics, such as plates, bowls, and dishes of tableware, which are usually decorated with enamel on the formed carcass. Porcelain glazes can be processed into colored glazes, and some colored glazes can be processed by firing temperature to form kiln changes, so that irregular patterns or crystalline patterns can be produced on the glaze surface. At present, in the industry using color glaze decoration, the patterns and patterns are not clear and beautiful enough to meet the refinement requirements of the design, and the cost is high and the production efficiency is low. And adopt color material to hand-paint or print to make decal paper, decorate pottery, do...
