Description

一种耐候陶瓷涂层材料
技术领域
本发明涉及陶瓷涂层技术领域，尤其涉及一种耐候陶瓷涂层材料。
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，提供一种耐候陶瓷涂层材料。
本发明是通过以下技术方案实现的：

所述一种耐候陶瓷涂层材料，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105-110℃下烘干，然后加到烧结炉中于480-500℃下预烧22-32min，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）将二硫化钼、硫酸钡和沸石在混料机中以1100转/分下搅拌，再喷入0.6%铝酸酯偶联剂研磨分散，再将其和氟硅乳液加到电炉中边加热边搅拌，烘干后研成细粉加到铝溶胶中超声分散；
（3）将步骤（1）制备的物料、氧化锆陶瓷粉和步骤（2）的物料混合，搅拌均匀后加到造粒机中制成颗粒，再将该颗粒用等离子喷涂技术喷到基体表面；
（4）将无碱玻璃粉末加热至熔融，然后将六方氮化硼、氧化铋、镍粉和三氧化二锑加入其中，恒温搅拌均匀，然后趁热涂覆在步骤（3）基体表面，激光熔覆后自然冷却即可。
所述一种耐候陶瓷涂层材料，所述玻璃釉料由白云石、多孔陶粒、红柱石、五氧化二铌和氧化镁组成，其中质量比为2-2.5：1.5-2:7.7-10:0.5-0.7:1-2。
本发明的优点是：本发明利用铝溶胶与陶瓷坯体成分的相容性以及促进烧结的特性将二硫化钼等物料超声成分散料，提高物料之间的粘结性、均匀性，再将其和玻璃釉料、陶瓷粉混合引起纳米复合相强韧化效应，减轻界面残余应力，在喷涂时能够减少陶瓷出现裂纹，减少结构缺陷，提高涂层的光滑、耐磨、易清洁等性能，本文还利用无碱玻璃粉良好的耐腐蚀、粘结性和六方氮化硼、氧化铋等混合，再利用激光熔覆技术将其涂覆在基体表面，解决涂层存在气孔的问题，并显著提高了涂层的硬度、耐高温、耐热震性、耐腐蚀性、导热性等性能；本发明的陶瓷涂层有效改善了表层陶瓷材料与基体的结合强度，同时保持了良好的防污、导热、耐候性能，使用寿命长，值得推广。
