Embodiment 1

[0017] Embodiment 1: a kind of black glaze, it is prepared by the raw material of following mass ratio: plant ash: 5 parts, cow dung ash: 5 parts, bentonite: 5 parts, burnt earth: 70 parts, blast furnace slag: 10 parts, Phosphate slag: 40 parts (the unit can be unified as gram); its preparation method is as follows: mixed glaze material: ball: water = 1:1.5:1 after mixing, wet ball milling for 20 minutes, 400r / min, the glaze The specific gravity is 1.5-1.6g / cm when the material is passed through a 250-mesh sieve 3 The glaze slurry is carefully and evenly applied to the ceramic biscuit, placed in a reducing atmosphere at a high temperature of 1200 ° C for 2 hours, and taken out after 1 hour of heat preservation. The color of the prepared ceramic glaze is relatively bright and uniform, and the artistic effect of thick and simple black colored glaze can be produced.

[0018] The plant ash is ground plant ash, and its fineness is required to pass through a 300-mesh sieve, that is...

Embodiment 2

[0021] Embodiment 2: a kind of black glaze, it is prepared by the raw material of following mass ratio: plant ash: 10 parts, cow dung ash: 10 parts, bentonite: 10 parts, burnt earth: 80 parts, blast furnace slag: 15 parts, Phosphate ore slag: 50 parts; its preparation method is as follows: mixed glaze material: ball: water = 1:1.5:1 after mixing, wet ball milling for 35 minutes, 450r / min, and pass the glaze through a 250-mesh sieve The specific gravity is 1.5-1.6g / cm 3 The glaze slurry is carefully and evenly applied to the ceramic biscuit, placed in a reducing atmosphere at a high temperature of 1200 ° C for 2.5 hours, and taken out after 1.5 hours of heat preservation. The prepared ceramic glaze is bright in color and high in transparency, and can produce a thick and simple artistic effect of black colored glaze.

Embodiment 3

[0022] Embodiment 3: a kind of black glaze, it is prepared by the raw material of following mass ratio: plant ash: 15 parts, cow dung ash: 15 parts, bentonite: 15 parts, burnt earth: 90 parts, blast furnace slag: 20 parts, Phosphate ore slag: 60 parts; its preparation method is as follows: mixed glaze material: ball: water = 1:1.5:1 after mixing, passed wet ball milling for 50 minutes, 500r / min, and passed the glaze through a 250-mesh sieve. The specific gravity is 1.5-1.6g / cm 3 The glaze slurry is carefully and evenly applied to the ceramic biscuit, placed in a reducing atmosphere at a high temperature of 1300 ° C for 3 hours, and taken out after 2 hours of heat preservation. The prepared ceramic glaze has a dark black surface, and the artistic effect of thick and simple black colored glaze can be produced.

Abstract

The invention relates to a glaze material prepared from waste and a method for preparing ceramic from the glaze material. The glaze material contains the following raw materials in parts by weight: 5-15 parts of plant ash, 5-15 parts of cow dung ash, 5-15 parts of bentonite, 70-90 parts of burnt soil, 10-20 parts of blast furnace slag and 40-60 parts of phosphorus slag. By recycling and utilizing agricultural and industrial waste such as the plant ash, the cow dung ash, the blast furnace slag and the phosphorus slag, the ceramic with a relatively transparent and smooth glaze surface and a metal luster is obtained. The preparation method is simple, the continuous production is easily realized, and the product is stable in quality and applicable to civilian decoration and courtyard decoration.

Description

technical field [0001] The invention relates to a glaze made from waste and a ceramic preparation method using the glaze, belonging to the technical field of ceramic material processing. Background technique [0002] The ecological pens are rationally divided into functional areas such as living, breastfeeding, manure storage, and forage storage, which improves the environment of the dairy pens and at the same time increases the manure storage and processing capacity. After treatment, SiO in cow dung ash 2 and Al 2 o 3 Reached 34.04%, 5.75%, Fe 2 o 3 The content is also 4.78%. After deodorization, wet ball milling, sieving and other processes, cow dung ash can become a good raw material for glaze. It is low in cost and economical, and can effectively solve the problem of cow dung pollution. [0003] At present, ceramic enterprises are facing problems such as shortage of raw materials and rising prices. With the increase of production costs and the intensification of pro...
