specific Embodiment approach 1

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the accompanying drawings:

[0019] A method for producing an underglaze that matches the green body and has a good glaze effect. Calcined kaolin, quartz, potassium feldspar, albite, calcite, talc, dolomite, zinc oxide, zircon powder, nephrite 2-30 kg each of stones are mixed as bottom glaze raw materials. In the bottom glaze raw materials, methyl cellulose is added as a thickener and an appropriate amount of water, and one of alkali, water glass, and sodium tripolyphosphate is added. As a water reducing agent, the quantity of adding the thickener and water reducing agent is 0.3-0.5% of the raw material of the bottom glaze, and the chemical composition is SiO 2 40-60%, Al 2 o 3 15-25%, CaO 5-15%, MgO 0-8%, K 2 O+Na 2 O 2-10%, ZnO 0-8%, ZrO 2 3-12%, water-reducing agent and thickener are 0-2%, and the fineness is 0.4-0.5% of the sieve-like bottom glaz...

specific Embodiment approach 2

[0024] Carry out according to specific embodiment 1, as shown in the accompanying drawings of the description, only: the bottom glaze production method that the matching body has a good glaze effect, calcined kaolin, quartz, potassium feldspar, and albite with a thickness of less than 100 mesh , calcite, talc, dolomite, zinc oxide, zircon powder, and nepheline are mixed as the raw material for the bottom glaze. In the raw material for the bottom glaze, add methyl cellulose as a thickener and an appropriate amount of water, and add a selective , water glass, and sodium tripolyphosphate as a water reducer, the amount of the thickener and water reducer added is 0.3-0.5% of the bottom glaze raw material, and the chemical composition is SiO 2 40-60%, Al 2 o 3 15-25%, CaO 5-15%, MgO 0-8%, K 2 O+Na 2 O 2-10%, ZnO 0-8%, ZrO 2 3-12%, water-reducing agent and thickener are 0-2%, and the fineness is 0.4-0.5% of the sieve-like bottom glaze finished product.

[0025] According to the...

specific Embodiment approach 3

[0029] Carry out according to specific embodiment 1, just as shown in the accompanying drawing of the specification, only: this matching green body has the bottom glaze production method of good glaze effect, and the composition of bottom glaze is set as SiO 2 54.40%, Al 2 o 3 13.86%, CaO 8.12%, MgO4.67%, K 2 O+Na 2 O5.72%, ZnO 3.80%, ZrO 2 8.52%, TiO2 0.24%, Fe 2 o 3 0.06%, loss on ignition 0.61%, select the corresponding proportion of ball clay, calcined kaolin, quartz, potassium feldspar, calcite, nepheline, zinc oxide, zircon powder, burnt talc as raw materials for the bottom glaze, according to the corresponding After mixing, add appropriate amount of water reducing agent, thickener and appropriate amount of water, put into a ball mill and grind into a glaze slurry with a fineness of 0.4-0.5% of the 10,000-hole sieve, and adjust the flow rate of the glaze slurry to 16-18 seconds. Also got the expected effect.

Abstract

The invention provides a method for producing a base coat being matched with a blank and having an excellent glazing effect and relates to the technical field of building materials. Materials are selected within a preset component scope of the base coat and the technology is standardized. The method comprises the following steps: mixing roasted kaolin, quartz, potash feldspar, soda feldspar, calcite, steatite, dolomite, zinc oxide, zircon powder and nepheline, which are less than 100 meshes and are 2-30kg, thereby obtaining the raw materials of the base coat; adding thickening agents, water reducing agents and a right amount of water into the raw materials of the base coat, wherein the thickening agents and the water reducing agents are both 0.3-0.5% of the raw materials of the base coat; and putting into a ball mill, thereby milling into a slurry base coat end product, wherein the end product comprises the following chemical components: 40-60% of SiO2, 15-25% of Al2O3, 5-15% of CaO, 0-8% of MgO, 2-10% of K2O+Na2O, 0-8% of ZnO, 3-12% of ZrO3, 0-2% of thickening agents and water reducing agents, and the fineness is 0.4-0.5% of ten-thousand hole screening. The method is used for producing the base coat. The base coat is matched with the blank and is excellent in glazing effect.

Description

technical field [0001] The invention relates to a method for producing an underglaze with a good glaze effect on a matched body, and relates to the technical field of building materials; in particular to the technical field of glass ceramic building materials; especially to the technical field of production methods for an underglaze in glass ceramic building materials; in particular to the technical field of a matching body with Technical field of production method of bottom glaze with good glaze effect. Background technique [0002] In the process of making glass ceramics, it is inseparable from the ceramic green body that matches the dry granules of the transparent frit. The ceramic green body needs to be glazed with a glaze machine. The implementation of the bottom glaze is an important factor that determines the quality of glass ceramic products. one. As far as the production of bottom glaze is concerned, it can be said that there are many kinds and different types at p...
