High-temperature anti-oxidation graphite product and preparation method thereof
The invention provides a high-temperature anti-oxidation graphite product and a preparation method thereof, and the method comprises the following steps: modifying nanoparticles by using a modifier to obtain hydrophilic modified nanoparticles; preparing the modified nanoparticles into an impregnation liquid; placing a graphite base material in a container, vacuumizing, introducing the impregnation liquid into the container to impregnate the graphite base material, and filling graphite pores with the impregnation liquid to obtain a graphite base material filled with modified nanoparticles; and sintering the graphite base material filled with the modified nanoparticles to form a high-temperature-resistant anti-oxidation coating on the surface of the graphite base material, thereby obtaining the high-temperature-resistant anti-oxidation graphite product. The high-temperature-resistant coating has a good anti-oxidation effect, has relatively strong binding force to a substrate, is uniform, reduces the porosity of graphite, and plays a role in protecting the graphite substrate.
本发明提供了一种高温抗氧化石墨制品及其制备方法，方法包含：利用改性剂对纳米粒子进行改性，得到亲水型改性纳米粒子；将所述改性纳米粒子制备成浸渍液；将石墨基材放置于容器中，抽真空，然后将所述浸渍液导入容器中使其浸渍所述石墨基材，使所述浸渍液填充石墨孔隙内部，得到填充有改性纳米粒子的石墨基材；将所述填充有改性纳米粒子的石墨基材进行烧结，即在石墨基材表面形成耐高温抗氧化涂层，得到高温抗氧化石墨制品。该耐高温涂层具有良好的抗氧化作用，对基底有较强的结合力，涂层均匀，同时减少石墨孔隙率，对石墨基材起到保护作用。
