Abstract

The invention discloses a ceramic mould, which is prepared from the following raw materials in parts by weight: 35-49 parts of gypsum, 1-2 parts of a reinforcing agent, 1-2 parts of a binding agent, 2-4 parts of additives, 6-8 parts of kaolin and 25-35 parts of water. A manufacturing method of the ceramic mould is strictly controlled, the specific gravity of each component of the ceramic mould isstrictly controlled, production process parameters are strictly controlled, the reinforcing agent and the binding agent are added into the raw materials, and gas holes in the manufactured ceramic mould can be effectively filled, so that density of the mould is higher, and the surface of the mould is smooth; before the mould is poured into an embossed mould, a gas exhaust tube is additionally arranged for continuously discharging gas, so that gas holes and gas bubbles of the mould are favorably reduced, and therefore, the manufactured mould quality is guaranteed, and durability is improved; andmeanwhile, guarantee is provided for processing ceramic later, so that the ceramic mould is suitable for being widely popularized.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a ceramic mold and a preparation method thereof. Background technique [0002] In 1877, the United States used clay as a binder to make ceramic grinding wheels, which marked the birth of ceramic molds. In 1930, ceramic molds began to choose the organization number. In 1970, ceramic binder cubic boron nitride grinding wheels appeared. In the 1980s Since then, foreign ceramic molds have developed rapidly and have a high level of technology. my country's ceramic molds have been developed since the 1950s. From the past to the present, ceramic molds have always occupied a dominant position in the overall composition of abrasive tools. Although with the continuous development of binder materials and the improvement of mold types, ceramic The output of molds shows a downward trend in the total output of molds, but it still occupies a large proportion of the total amount of molds.
