Description
技术领域
本发明涉及一种陶瓷基材料,具体是一种耐高温陶瓷基复合材料及其制备方法。
背景技术
陶瓷基复合材料是以陶瓷为基体与各种纤维复合的一类复合材料。陶瓷基体可为氮化硅、碳化硅等高温结构陶瓷。这些先进陶瓷具有耐高温、高强度和刚度、相对重量较轻、抗腐蚀等优异性能,而其致命的弱点是具有脆性,处于应力状态时,会产生裂纹,甚至断裂导致材料失效。而采用高强度、高弹性的纤维与基体复合,则是提高陶瓷韧性和可靠性的一个有效的方法。纤维能阻止裂纹的扩展,从而得到有优良韧性的纤维增强陶瓷基复合材料。现有的陶瓷基复合材料虽然具备耐高温的优点,但是对于超高温情况下效果依然不佳,因此,需要对现有的陶瓷基复合材料进行改进,提高其耐高温性。
发明内容
本发明的目的在于提供一种耐高温陶瓷基复合材料及其制备方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:
一种耐高温陶瓷基复合材料,按重量份数,包括有石墨烯陶瓷粉料100-150份,水玻璃1-2份,改性粘结剂5-8份,水2-4份;其制备方法,包括以下步骤:
第一步:将水加入石墨烯陶瓷粉料中搅拌,再加入水玻璃、改性粘结剂共同搅拌混合,搅拌时间30-60分钟,搅拌温度50-80摄氏度;
第二步:混合的原料送入真空干燥设备中进行干燥,干燥时间30分钟,温度为110-120摄氏度,干燥后取出静置冷却;
第三步:破碎后放入造粒机中加工,制得粒度为0.04-0.08mm粉料;
第四步:将造粒粉装入模具中,等静压成型得到毛坯;将毛坯烧结成瓷或对毛坯进行进一步车削加工后再烧结成瓷。
石墨烯是一种由sp2杂化的碳原子以六边形周期排列形成的二维结构,其厚度只有0.335nm,是目前世界上发现的最薄却最坚硬的材料,同时也是其他维度碳材料的基本结构单元。陶瓷基复合材料是一种以陶瓷为基体与其它材料复合而成的材料,其中陶瓷基体可为氧化硅、氧化铝、氧化锆或氧化钛等氧化物陶瓷,也可为碳化硅、碳化硼或硼化钛等非氧化物陶瓷。这些陶瓷材料大多具有耐高温、高强度和刚度、相对重量较轻、抗腐蚀等优异性能,而其致命的弱点是具有脆性,处于应力状态时,会产生裂纹,而裂纹极易发生扩展,致使整个材料断裂失效。而采用石墨烯与基体复合,是提高陶瓷韧性和使用可靠性的有效方法。石墨烯的加入对裂纹尖端有着桥连作用,并能够延长裂纹扩展的路径,从而得到有优良力学性能的石墨烯增强陶瓷基复合材料。
作为本发明进一步的方案:所述的石墨烯陶瓷粉料,按重量份数计算,包括有陶瓷泥粉50-80份,石墨烯粉料5-10份,分散剂1-2份,氧化铝5-10份,硼酸锌2-4份,分散剂采用乙醇、异丙酮或二甲基甲酰胺;其制备方法,包括以下步骤:
第一步:将陶瓷泥粉、石墨烯粉料、分散剂、氧化铝、硼酸锌、加水混合搅拌,搅拌时温度为50-80摄氏度度,形成石墨烯陶瓷悬浊液;对氧化铝需进行热处理,使其晶相由β-Al2O3转变成α-Al2O3,对热处理后的氧化铝粉进行研磨,粒度小于1000目筛;
第二步:将上述悬浊液放入干燥设备中,缓慢搅拌悬浊液,将悬浊液中的水分蒸发,取干燥后粉末静置冷却;
第三步:将粉末送入到研磨设备中研磨30分钟,过100目筛后获得石墨烯陶瓷粉料;
作为本发明再进一步的方案:所述的改性粘结剂,按重量份数计算,聚乙烯蜡50-60份,石油醚2-4份,过氧化苯甲酰1-2份,丙烯酸1-2份,其制备方法包括以下步骤:
第一步:将聚乙烯蜡与石油醚在容器中加热至90~100摄氏度,搅拌使聚乙烯蜡溶解;
第二步:再加入过氧化苯甲酰和丙烯酸,在过氧化苯甲酰的作用下接枝丙烯酸,接枝反应结束后,降温至5~20℃即可析出产物。
聚乙烯蜡的分子量为2000~5000,聚乙烯蜡(PEW)的接枝改性主要是在非极性聚乙烯蜡碳链上引入-COOH、-CO-、-CONH2、-COOR等极性基团,极性基团的引入,使得其在溶解、乳化、分散、润滑、偶联等性能方面得到明显的改进,扩大了聚乙烯蜡的应用。
改性粘结剂液具有抗酸、抗碱、耐硬水、水溶性强、乳液稳定,任意比例水稀释不分层、不破乳、不结块、保质期长、固含量高、分散性好等特点,并有很好的抗划伤、防水、抗粘防污、耐磨、柔软、表面润滑等的性能。
与现有技术相比,本发明的有益效果是:在陶瓷基中添加石墨烯粉料,石墨烯具有规则的平行排列,使得材料的力学性能良好以及良好的耐高温性,抗热震性得到提高,显微结构得到改善,材料整体性能得到提升,提高了材料的使用可靠性、耐久性和安全性,使陶瓷基的使用范围更广。
