Description

一种耐磨复合涂层材料
技术领域
本发明涉及陶瓷涂层技术领域，尤其涉及一种耐磨复合涂层材料。
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。

（2）将石英砂、氟碳树脂破碎后和氧化铝陶瓷粉、氟化石墨在混料机中以1000转/分下搅拌均匀，将硅烷偶联剂kh550用适量的无水乙醇稀释喷涂在混合粉末中，然后加到造粒机中制成颗粒备用；
（3）将步骤（1）制备的物料和步骤（2）制备的产物混合加到电炉中，在电炉中边加热边搅拌，直至烘干，自然冷却后球磨成粒径为25-40μm的粉末，再将粉末用等离子喷涂技术喷到基体表面；
（4）将疏水性气相白炭黑、硅烷偶联剂a174、镍钴合金和氮化硅投入到动力混合机中搅拌10-20min，再加入环氧树脂乳液继续搅拌混匀，然后打开真空泵，使机内真空度保持在0.09-0.095MPa条件下搅拌得到胶体停止，然后将胶体涂覆在步骤（3）基体表面，激光熔覆后自然冷却即可。
所述一种耐磨复合涂层材料，所述玻璃釉料由硅藻土、氧化镁、二氧化硅、粉煤灰和钾长石组成，其中质量比为2-2.5：1.2-1.8:3-3.5:2-2.5:6-8。
本发明的优点是：本发明利用硅烷偶联剂将石英砂、氟碳树脂、氟化石墨和氧化铝陶瓷粉偶联造粒，使其具有良好的粘结性和分散性，然后和玻璃釉料一起加热搅拌，利用等离子喷涂到基体表面能够减少陶瓷出现裂纹，减少结构缺陷，提高涂层的极耐磨性、光滑性、防污性等性能，再利用环氧树脂乳液良好的粘结性、抗氧化性等将偶联的白炭黑等通过动力混合机搅拌得到胶体，再利用激光熔覆技术将其涂覆在基体表面，解决涂层气孔、表面粗糙的问题，并显著提高了涂层的硬度、化学稳定性、耐磨性、抗氧化性等性能；本发明有效提升排风设备表面的强硬度，使在运行时具有更高的耐磨性能，使用寿命明显提高，同时陶瓷材料来源丰富，生产成本得到有效控制，适合大规模生产。
