A kind of graphite anti-leakage material, graphite material and preparation method

Abstract

The present invention proposes a graphite anti-leakage material, a graphite material and a preparation method, the method comprising: stirring a synthetic resin in a stirring container, adding a diluent while stirring, and diluting to a viscosity of 16-50mpa. s; then continue to stir for 2‑4 hours to form a spare resin; dry carbon, titanium, boron, calcium, nitrogen, and oxygen and pulverize them to a particle size of no more than 10 μm; mix the raw materials and add the spare resin during mixing , until a lump is formed; continue to stir the mixture for 3-5 hours, then let it stand for 8-16 hours; continue to stir the resulting mixture for 3-5 hours, and continue to add the spare resin while stirring until the viscosity reaches 30- 100mpa.s, and the relative density of the liquid reaches 1.89g / cm 3 ‑2.35g / cm 3 ; The mixture obtained in step 105 was stirred for 10 hours to achieve a relatively good fluidity state, and left to stand for 18 hours to obtain a graphite anti-leakage material.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a graphite anti-leakage material, a graphite material and a preparation method. Background technique [0002] Various containers have been widely used in smelting related industries. Due to its special crystal structure, graphite has many characteristics such as high temperature resistance, thermal shock resistance, electrical conductivity, lubricity, and chemical stability. Strategic resources with a wide range of applications. In the prior art, in order to improve the thermal conductivity and strength of graphite containers, graphite materials with low expansion rate, high thermal conductivity and high elastic modulus are usually selected when processing graphite containers to improve the thermal shock resistance of graphite containers. [0003] But when using this existing graphite container, generally there is a problem: graphite is a kind of porous material, so leakage p...
