Abstract

The invention discloses a ceramic composite material and a preparation method thereof. The ceramic composite material is prepared from components in parts by weight as follows: 75-90 parts of ZrB2-SiC, 20-30 parts of kaolin, 6-10 parts of nano-zirconia, 3-5 parts of nano-alumina, 2-6 parts of nano-magnesia, 1-6 parts of nano-titania, 3-10 parts of carbon fiber, 4-8 parts of glass fiber, 6-8 partsof attapulgite, 10-12 parts of diatomite, 10-15 parts of tourmaline, 10-15 parts of medical stone, 5-10 parts of polyethylene glycol and 3-6 parts of a silane coupling agent. According to the ceramiccomposite material, ZrB2-SiC powder is used as a main raw material, the prepared ceramic composite material has good high-temperature resistance and electrical and thermal conductivity and higher mechanical strength and chemical stability, besides, natural substances such as tourmaline, medical stone, attapulgite, diatomite and the like are added and serve as main materials, the raw materials arewidely sourced, and the ceramic composite material has characteristics of releasing anions, radiating far infrared rays, resisting bacteria, removing chlorine and noble metal and the like; with addition of the carbon fiber and the glass fiber, toughness of the ceramic can be improved.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a ceramic composite material and a preparation method thereof. Background technique [0002] Ceramic materials are a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. It can be used as structural material, tool material, and because ceramics also have some special properties, they can also be used as functional materials. The properties of ceramics prepared from different raw materials are different. Improving the mechanical properties, thermal properties, electrical properties and other properties of ceramic properties is a problem that needs to be further solved for ceramic materials. [0003] Composite materials usually have good comprehensive properties of different materials compl...
