Problems solved by technology

In the prior art, in order to reduce energy consumption, pure flux raw materials are added to the ceramic body, and the maximum firing temperature is reduced from about 1360°C to about 1270°C, and energy consumption is also reduced accordingly, but pure flux raw materials cannot It plays the role of improving the internal structure of the porcelain blank. The internal quality of the product, such as density, mullite crystal phase content, compressive performance, etc., is far from that of the product fired at high temperature, so that the product falls into the category of medium temperature ceramics, affecting Improve the enterprise benefit and ceramic use effect

Abstract

The invention discloses a compression-resistance compound additive applied to ceramic and a preparation method thereof and relates to the technical field of ceramic additives. The compound additive disclosed by the invention is prepared from the following raw materials in parts by weight: 20 to 40 parts of rutile type titanium dioxide, 15 to 30 parts of albite, 10 to 20 parts of calcite, 5 to 12 parts of shell powder, 3 to 8 parts of silicon nitride, 1 to 6 parts of waterborne polyurethane, 2 to 5 parts of ferric oxide, 1 to 3 parts of white carbon black, 0.2 to 0.6 part of vanadium pentoxide,0.1 to 0.5 part of dispersing agent and 0.02 to 0.08 part of grinding agent. The preparation method comprises the steps of mixing the materials, sintering at high temperature and superfinely grinding. The compound additive disclosed by the invention reduces a sintering temperature of a ceramic green body and improves compactness, crush resistance, seismic resistance and a mullite crystal phase content of ceramic at the same time; furthermore, the compound additive has the advantages of high efficiency and small use quantity; cost is saved.

Description

Technical field: [0001] The invention relates to the technical field of ceramic additives, in particular to a pressure-resistant composite additive for ceramics and a preparation method thereof. Background technique: [0002] With the continuous improvement of people's requirements for the quality of ceramic products, as well as the country's urgent requirements for energy conservation and emission reduction in traditional manufacturing industries, while further reducing the water content of ceramic slurry, improving the grinding efficiency of ceramic blanks, improving plasticity and other technological properties have also changed. become more and more important. In the prior art, in order to reduce energy consumption, pure flux raw materials are added to the ceramic body, and the maximum firing temperature is reduced from about 1360°C to about 1270°C, and energy consumption is also reduced accordingly, but pure flux raw materials cannot It plays the role of improving the ...
