Description
技术领域
本发明涉及陶瓷加工技术领域,尤其是涉及一种耐高温陶瓷及其制备方法。
背景技术
陶瓷在我国具有较长的发展史,随着社会的不断发展,在很多领域得到广泛的应用,陶瓷分为工业陶瓷和日用陶瓷,由于工业用陶瓷如化工冶炼或者其他热工设备使用的陶瓷对其耐高温性能的要求逐渐提高,因此也刺激了耐高温陶瓷材料的进一步发展。目前耐高温陶瓷材料通常通过添加单一耐高温材料如氧化铝、氮化硅等材料来提高其耐高温性能,但是其耐高温性能还亟待进一步得到提高,此外耐高温陶瓷材料在加工过程中还容易出现不易进行粘结的缺点。
发明内容
针对现有技术的不足,本发明所要解决的技术问题是提供一种耐高温陶瓷及其制备方法,制备得到的耐高温陶瓷具有较好的耐高温性能,并且在加工的过程中粘接性很好,制备得到的陶瓷不易裂纹。
本发明所采取的技术方案是:
本发明提供了一种耐高温陶瓷,包括以下重量份的原料:18~25质量份的陶土、4~6质量份的菱镁石、2~4质量份的氧化镁、1~3质量份的氧化镍、8~10质量份的改性氮化硼、30~50质量份的有机硅树脂和6~10质量份的助溶剂,所述改性氮化硼由氮化硼经多巴胺改性制得。
优选地,所述有机硅树脂为甲基苯基硅树脂。
优选地,所述改性氮化硼由氮化硼加入10wt%~15wt%多巴胺改性制得。本申请中多巴胺的质量分数是以氮化硼的质量为基准。
进一步地,所述氮化硼为氮化硼纳米管。
优选地,所述助溶剂为碳酸钠、乙二胺盐、硝酸钠中的至少一种。
本发明还提供一种上述的耐高温陶瓷的制备方法,包括以下步骤:
(1)取陶土粉末进行干燥,加入菱镁石、氧化镁、氧化镍和改性氧化硼混合均匀形成混合粉末;
(2)在所述混合粉末中加入助溶剂,缓慢加入有机硅树脂,搅拌混合得到预混料;
(3)取模具预热至60~90℃,在模具内表面涂覆脱模剂,将所述预混料送入模具内进行冲压成型并脱模;
(4)将步骤(3)中脱模后的材料送入烧结装置内在1000~1600℃进行加热烧结。
优选地,步骤(3)中冲压成型的压力为10~30MPa,冲压时间为20~200min。
优选地,步骤(4)中采用程序升温的方式进行加热烧结。
进一步地,步骤(4)中程序升温的升温速率为3~6℃/min。
本发明的有益效果是:
本发明提供了一种耐高温陶瓷,通过在原料中添加改性氮化硼来提高其耐高温性能,氮化硼由于其表面惰性直接与无机材料结合容易出现界面结合不足的问题,本发明利用多巴胺对氮化硼进行表面改性,在其表面形成化学键提高了氮化硼与无机材料的界面结合力,进而提高了改性氮化硼与其他无机耐高温材料氧化镁和氧化镍的结合力,此外加入的菱镁石和有机硅树脂与其他原料组分进一步协同作用促进了陶瓷的粘结力和耐高温性能,制备得到的陶瓷不易裂纹。
