High-thermal-insulation material for diamond synthesis and preparation process of high-thermal-insulation material
The invention discloses a high thermal insulation material for diamond synthesis and a preparation process thereof, and the high thermal insulation material comprises the following components: Nacl fine powder, dolomite, silicon carbide, magnesium oxide, aluminum oxide, zirconium oxide, micro-expansive concrete, asbestosed wire gauze and ceramic fine powder. The mixing ratio of the Nacl fine powder to the dolomite to the silicon carbide to the magnesium oxide to the aluminum oxide to the zirconium oxide to the micro-expansive concrete is 5-7%, 15-20%, 3-8%, 2-5%, 5-12%, 2-3% and 45-68%, the micro-expansive concrete and the ceramic fine powder are mixed to cover the surface of the high thermal insulation material, and the preparation process comprises the following steps: S1, crushing and premixing the raw materials; s2, pre-sintering is carried out; s3, crushing; s4, mixing the additives; s5, molding and pressing; and S6, roasting. According to the invention, the adhesion between high thermal insulation materials is enhanced through the asbestosed wire gauze, the micro-expansive concrete is matched to reduce the expansion after heating, cracks generated after heating are effectively avoided, and the shell formed by the ceramic fine powder can achieve stronger high temperature resistance and is beneficial to improving the synthesis effect of the diamond.
