Special ceramic and preparation method thereof

Abstract

The invention discloses special ceramic which is prepared from the following raw materials in parts by weight: 3-4 parts of wollastonite, 10-14 parts of feldspar, 5-7 parts of aluminum oxide, 20-25 parts of kaolin, 58-66 parts of quartz, 2-3 parts of nano-zinc oxide, 2-3 parts of oleic acid, 1-2 parts of oxidized paraffin, 12-15 parts of zirconium oxychloride, 3-4 parts of sodium zirconate, 3-4 parts of tetraethoxysilane, a proper amount of deionized water, 1-2 parts of potassium hydroxide, a proper amount of ethanol and 4-6 parts of an additive. The ceramic disclosed by the invention is relatively wide in temperature resistance, good in ablation resistance, good in mechanical property and large in strength, due to the addition of zirconium oxychloride and sodium zirconate, the wearing resistance and the temperature resistance of the ceramic are improved, the ceramic is not easy to break, resistant to vibration and long in service life, and due to the addition of the additive, the surface smoothness, wearing resistance and thermal resistance of the ceramic are improved.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a special ceramic and a preparation method thereof. Background technique [0002] At present, the materials used for channels and pipes include aluminum alloy materials, ceramics, etc. Aluminum alloy materials have poor wear resistance, and the channels are easy to disappear, which affects the accuracy of color selection. They need to be replaced frequently and the cost is high; Not too high, not resistant to cold and heat stimulation, poor acid and alkali resistance, so it is necessary to research ceramic materials with good wear resistance, high hardness, good toughness, vibration resistance, heat resistance, corrosion resistance, etc., to reduce costs. Contents of the invention [0003] The object of the present invention is to provide a special ceramic and its preparation method. The ceramic has wide temperature resistance, good ablation resistance, good mechanical properti...
