Description

一种延长排风叶片寿命的涂层材料
技术领域
本发明涉及陶瓷涂层技术领域，尤其涉及一种延长排风叶片寿命的涂层材料。
背景技术
排风设备在厨房、实验室、工厂等各领域都有重要的作用。一般都可以分成排风罩、风管、除尘净化设备、风机、设备壳等部分组成。其中除尘净化设备的材料是根据领域的不同采用的材质也不尽相同，大多数会采用合金材料，合金材料的性能很大程度上影响了设备使用效果和寿命。陶瓷涂层在摩擦过程中产生的热应力比较小，涂层不容易发生严重断裂，具有孔隙率低、摩擦系数低、导热系数高、耐腐蚀性、高硬度等特性，适用于高温、腐蚀和磨损等特殊工作环境。
《Cr2O3陶瓷涂层摩擦磨损性能研究》中利用三氧化二铬陶瓷粉末与玻璃釉料按照一定质量比混合，烧结900℃后球磨，过200目筛，然后利用亚音速喷枪在45钢上喷涂三氧化二铬陶瓷涂层，并在电阻炉中烧结。虽然加入一定量的玻璃釉料增强了粉末之间的粘结性，提高了涂层的耐磨性，但是喷涂制得的涂层无法将空气全部排出，存在大量气孔，即使经过高温烧结也无法改善，需要多次涂刷玻璃釉料，施工复杂，并且铬对人体有毒性，不宜大量使用。本发明针对排风设备的使用性能，认为防污易清洁是最主要的实用性能，利用参考文献提出的玻璃釉料增强烧结性、提高耐磨性，将两者结合起来制备出适宜工业化大生产的提高排风设备性能的陶瓷涂层。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种延长排风叶片寿命的涂层材料。
本发明是通过以下技术方案实现的：
一种延长排风叶片寿命的涂层材料，由以下重量份的原料制备制成：玻璃釉料12-15、氧化铝陶瓷粉70-80、镍铬合金3-3.6、环氧树脂0.9-1.3、二氧化硅1.8-2、木质素磺酸钠0.2-0.4、锆酸钠1.4-1.6、碳化硅纤维0.4-0.6、羧甲基纤维素0.4-0.6、碳化坦4-5、竹炭粉0.3-0.4、无水乙醇适量、去离子水适量。
所述一种延长排风叶片寿命的涂层材料，由下列具体步骤制备制成：
(1)将玻璃釉料中加入适量的无水乙醇，在行星球磨机内湿法球磨5-7h，球磨完毕后在100-110℃下烘干，然后加到烧结炉中于500-550℃下预烧20-35min，冷却后再加入适量粘结剂制成粒度为10-30μm的细粉料，烘干后备用；
（2）将二氧化硅、木质素磺酸钠、锆酸钠和碳化硅纤维中加入适量的无水乙醇在研钵中研磨分散，喷雾干燥后加到水性聚氨酯乳液中以1200转/分搅拌，然后和氧化铝陶瓷粉混合在电炉中边加热边搅拌，直至烘干；
（3）将步骤（1）制备的物料在基材表面迅速喷涂均匀厚度，使其形成底层，再将步骤（2）制备的物料送入热喷涂系统送粉器内，设置参数利用等离子喷涂技术喷到基材表面；
（4）将环氧树脂、镍铬合金、碳化坦和竹炭粉加到研磨机中研磨粉碎，再加入润湿剂制成小颗粒，将颗粒和质量浓度为3-4%的羧甲基纤维素溶液搅拌混合，均匀后涂覆在步骤（3）基体表面，激光熔覆后自然冷却即可。
所述一种延长排风叶片寿命的涂层材料，所述玻璃釉料由钠长石、氧化钇、陶土、硅灰石和硼砂组成，其中质量比为9-10：0.2-0.3:2.5-3:1-1.5:0.8-1。
本发明的优点是：本发明利用玻璃釉料在基材表面先形成一层涂层，再利用水性聚氨酯乳液无毒无污染、相容性好的特点将锆酸钠等材料涂覆在玻璃涂层上，利用等离子喷涂能够引起增强相之间强韧化效应，减少陶瓷涂层出现瑕疵，提高涂层的质量，还利用环氧树脂、合金、竹炭粉等不同物料之间搭配制备成颗粒，再利用激光熔覆技术将硬质颗粒附着涂层上，解决了涂层存在气孔的问题，并显著提高了涂层的高强、耐腐蚀、高温抗氧化、耐磨等性能；本发明采用的原料组分简单,廉价易得,形成的涂层具有良好的高温抗氧化和强度以及优异的耐磨、耐腐性能,且工艺简洁易操作,适于大规模化生产。
