Description

Technical Field

[0001] The invention belongs to the technical field of daily-use stoneware glaze preparation, and particularly relates to a reticulated relief glaze and a preparation method thereof. Background Art

[0002] Daily-use ceramics mainly include fine porcelain, stoneware, fine pottery, and coarse pottery. The main difference lies in the water absorption rate of the finished ceramics. The water absorption rate of stoneware is between 0.5% and 3%, and the firing temperature is between 1160 and 1260 degrees Celsius. Stoneware is mainly decorated with colored glazes. Because the firing temperature is relatively low, it is suitable for the coloring of various inorganic ceramic pigments, so colored glaze stoneware is currently popular in the world. Colored glaze stoneware pursues novelty, novelty, and uniqueness in decoration, and at the same time gives it certain cultural connotations or other aesthetic wills. Colored glaze stoneware truly makes daily-use ceramics artistic and artistic ceramics daily-use.

[0003] The invention patent with patent publication number CN104016722A discloses a reaction glaze with relief effect, including a base glaze and a surface glaze, characterized in that the components of the base glaze and the mass parts of each component are as follows: feldspar: 31 parts to 35 parts; quartz: 20 parts to 23 parts; calcite: 12 parts to 15 parts; Guizhou soil: 4 parts to 5 parts; zinc oxide: 2.5 parts to 5 parts; zirconium silicate: 8 parts to 10 parts; strontium carbonate: 5 parts to 8 parts; the components of the surface glaze and the mass parts of each component are as follows: feldspar: 23 parts to 25 parts; borax: 20 parts to 25 parts; quartz 12 parts to 15 parts; calcite: 15 parts to 18 parts; Guizhou soil 3 parts to 5 parts; zinc oxide: 15 parts to 17 parts; zirconium silicate: 8 parts to 10 parts; titanium oxide 9 parts to 10 parts; color base: 11 parts to 15 parts. This technical solution can make the glaze surface appear concave and convex, with a simple relief effect, but it cannot achieve complex relief effects and has limitations.

[0004] The patent application with the patent publication number CN104909832A discloses a gold metal glaze and its preparation method. The components and mass percentages of the gold metal glaze are as follows: potassium feldspar: 35-40 parts; kaolin: 5-8 parts; quartz: 8-12 parts; high expansion coefficient frit: 3-5 parts; barium carbonate: 4-7 parts; high lead frit: 15-25 parts; vanadium pentoxide: 1-2 parts; manganese dioxide: 10-12 parts; copper oxide: 1-3 parts; talc: 1-2 parts. This patent is a glaze formula. By adding high lead powder, it breaks the traditional lead-free metal glaze mode. It can make the metallic luster of the oxide more stable, but it does not have a relief effect. Because it contains lead, it is not suitable for the production of daily-use porcelain for export, that is, it does not meet the export quality standards.

[0005] In the prior art, the embossed glaze production process requires the use of a special rubber roller or a printing screen with optimized mesh count to print the special glaze on the base glaze and top glaze, and then sinter at high temperature to make the special glaze pattern sink into the ordinary top glaze. In view of the defects of the prior art, it is of great significance to research and develop a mesh-like embossed glaze to meet the current market demand. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a mesh relief glaze and a preparation method thereof, so as to obtain a mesh relief glaze with low lead and cadmium content, high thermal stability, warm gloss and delicate touch.

[0013] The spray glaze comprises the following raw materials in parts by weight: 16 parts of 3# frit, 40 parts of potassium feldspar, 10 parts of quartz, 12 parts of calcite, 5 parts of barium carbonate, 2 parts of calcined talc, 5 parts of calcined zinc, 10 parts of longyan mud, and 8 parts of vanadium pentoxide.

[0014] Another object of the present invention is to provide a method for preparing the above-mentioned reticulated relief glaze, comprising the following steps:

[0015] (1) preparing a ceramic wet blank and drying it to form a ceramic dry blank;

[0016] (2) Applying a base glaze on the surface of the ceramic blank, spraying a top glaze, and finally spraying a spray point glaze of appropriate size to form a ceramic glaze blank;

[0017] (3) drying the ceramic glaze blank to make the moisture content of the blank less than 1%;

[0018] (4) The dried body is put into a kiln for firing to obtain a mesh-like relief glaze product.

[0019] In one embodiment, the thickness of the base glaze in step (2) is 0.10-0.25 mm.

[0020] In one embodiment, the thickness of the glaze in step (2) is 0.10-0.15 mm.

[0021] In one embodiment, the average particle size of the base glaze and top glaze slurry in step (2) is 40-60 μm.

[0022] In one embodiment, the drying temperature of the ceramic wet blank in step (1) is 100-120° C., and the drying time is 70-90 min.

[0023] In one embodiment, the drying temperature of the ceramic glaze blank in step (3) is 100-120° C., and the drying time is 30-50 min.

[0024] In one embodiment, the sintering atmosphere in step (4) is an oxidizing atmosphere.

[0025] In one embodiment, the sintering temperature in step (4) is 1170-1210°C.

[0026] The compositions of the 2# frit and the 3# frit are:

[0027] <![CDATA[SiO2]]> <![CDATA[Al2O3]]> <![CDATA[B2O3]]> CaO MgO <![CDATA[K2O]]> <![CDATA[Na2O]]> <![CDATA[Li2O]]> 2# Frit 58 7.2 13 6.8 1.5 6.2 7 / 3# Frit 56.2 14 8.1 9.4 / 2 9.5 0.5

[0028] Beneficial effects of the present invention:

[0029] (1) The present invention is presented in the form of three layers of glaze, wherein the base glaze is mainly bright glaze; the surface glaze (middle layer) is mainly bright glaze, which has a certain viscosity and maintains a certain fluidity, and is well combined with the base glaze but has obvious layers, and does not melt or react with each other; then, a uniform coarse dot glaze is sprayed on the two layers of glaze, and the top coarse dot glaze produces a depression, which squeezes the surface glaze (middle layer) glaze to form a mesh, and the base glaze also sinks relatively without exposing the body, forming a net-shaped relief effect, a net-shaped relief glaze with a delicate touch and a warm gloss;

[0030] (2) Adding vanadium pentoxide to the spray glaze formula can enhance the transparency and color layering of the glaze surface. Adding too little will easily lead to unclear relief effect, while adding too much will easily lead to too obvious relief effect and even expose the embryo.

[0031] (3) Adding zirconium silicate to the glaze formula can not only improve the body-glaze separation performance of the ceramic, but also play a role in whitening. Too little addition can easily lead to poor glaze flow and blurred reticulation effect;

[0032] (4) The three-layer glaze of the present invention needs to be added in strict proportion. If a certain component of the glaze formula is added too much or too little, it will affect the relief effect, glaze gloss, texture and other effects of the relief glaze;

[0033] (5) The preparation process of the present invention is simple, the content of lead and cadmium is low, the thermal stability is high, the gloss is warm, and the textured relief glaze with delicate touch is produced. All indicators meet the relevant standard requirements, and the present invention has strong universality and is easy to promote and apply in the industry. The present invention can control the base glaze color and the texture color as needed, which can better meet the design requirements and adapt to customer needs. DETAILED DESCRIPTION
