Composite refractory material and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a composite refractory material and a preparation method thereof. The composite refractory material is prepared from the following raw materials in parts by weight: 20 to 40 parts of diatomite, 50 to 70 parts of kaolin, 10 to 20 parts of hydrophilic vapor-phase silicon dioxide, 15 to 35 parts of zirconium dioxide, 6 to 10 parts of fired magnesium aluminate spinel fine powder, 20 to 38 parts of hollow glass beads, 15 to 32 parts of expanded vermiculite powder, 6 to 10 parts of silicon carbide whiskers, 10 to 20 parts of silane coupling agent, 6 to 8 parts of hexagonal boron nitride, 90 to 100 parts of water and 60 to 70 parts of absolute ethyl alcohol. The silicon carbide whiskers modified by the silane coupling agent can effectively prolong the fire-resistant time of the prepared composite material and improve the high-temperature breaking strength of the material, so that the fire-resistant performance of the composite material is enhanced, and the composite material can meet the use requirements of a refractory material; and secondly, hexagonal boron nitride is added, so that the normal-temperature breaking strength of the material can be effectively enhanced.
本发明涉及耐火材料技术领域，尤其涉及一种复合耐火材料及其制备方法。所述复合耐火材料包括以下重量份的原料：20～40份硅藻土、50～70份高岭土、10～20份亲水气相二氧化硅、15～35份二氧化锆、6～10份烧制镁铝尖晶石细粉、20～38份空心玻璃微珠、15～32份膨胀蛭石粉、6～10份碳化硅晶须、10～20份硅烷偶联剂，6～8份六方氮化硼、90～100份水、60～70份无水乙醇。本发明通过应用硅烷偶联剂改性的碳化硅晶须，能有效延长所制备复合材料的耐火时间，同时提高材料的高温抗折强度，从而增强复合材料的耐火性能，使所述复合材料能满足耐火材料的使用要求；其次通过加入六方氮化硼，能有效增强材料的常温抗折强度。
