Carbon source for refractory material and preparation method thereof
The invention provides a carbon source for preparing a refractory material, the carbon source is composed of a powder raw material core and a nanocarbon outer layer, the thickness of the nanocarbon layer coating the surface of the powder raw material is 2-100nm, preferably 5-50nm, and the powder raw material is selected from magnesium oxide, aluminum oxide, mullite or clay. The invention also provides a preparation method of the carbon source for preparing the refractory material, which comprises the following steps: by using commercially purchased powder raw material particles as a raw material, preparing the carbon source coated with a nano-thickness carbon layer by using a vapor deposition method, a liquid phase method or a hot melting method. According to the nano carbon source with the shell-core structure, a nano-thickness carbon layer is uniformly coated on the surface of a refractory material raw material, so that high dispersion of carbon is realized, and the nano carbon source is suitable for various refractory materials including but not limited to magnesia-carbon bricks, alumina-carbon bricks, calcium-carbon bricks, magnesia-alumina-carbon bricks, clay-carbon bricks andkaolin-carbon bricks; the invention also provides other refractory material products prepared from one or more than two refractory material raw materials.
本发明提供一种用于制备耐火材料的碳源，所述碳源由粉末原料内核和纳米碳外层构成，其中包覆在粉末原料表面的纳米碳层厚度为2‑100nm，优选为5‑50nm，所述的粉末原料选自氧化镁、氧化铝、莫来石或黏土。本发明还提供一种用于制备耐火材料碳源的制备方法，以商业上购买的粉末原料颗粒为原料，使用气相沉积法、液相法或热熔融法制备得到包覆一层纳米厚度碳层的碳源。本发明所述壳核结构的纳米碳源实现了纳米厚度的碳层在耐火材料原材料表面均匀包裹从而实现了碳的高度分散，适用于各类包含碳耐火材料含但是不限于：镁碳砖、铝碳砖、钙碳砖、镁铝碳砖、黏土碳砖、高岭土碳砖，以及其他包含一种或两种以上的耐火材料原料所制作而成的耐火材料产品。
