Description

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

所述一种耐紫外的复合陶瓷涂层材料，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98-110℃下烘干，然后加到烧结炉中于520-550℃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）将拟薄水铝石和去离子水按照质量比0.1-1:1球磨3-4h，再加入二硼化钛、氧化镍继续球磨2-3h得浆料；
（3）将步骤（1）制备的物料和步骤（2）制备的浆料混匀，搅拌均匀后再加入骨料和氧化锆陶瓷粉在电炉中边加热边搅拌形成颗粒，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）将聚偏氟乙烯用适宜的二甲基乙酰胺溶解成胶体溶液，将碳化铌、碳化硼和氧化铜分散于上述胶体溶液中，形成有机无机分散液，将分散液均匀涂覆在步骤（3）基体表面，激光熔覆后自然冷却即可。
所述一种耐紫外的复合陶瓷涂层材料，所述玻璃釉料由硅灰石、木鱼石粉、凹凸棒石、碳酸锂和氧化钙组成，其中质量比为2-2.5：1.2-1.5:4-5:2-2.5:5-7。
本发明的优点是：本发明利用拟薄水铝石胶溶性好、粘结性强等特点研磨成浆料，再和玻璃釉料浸渍混合，可以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，提高涂层与基体的粘结性、耐磨、硬度等性能，本文还利用碳化铌、碳化硼等在聚偏氟乙烯胶体溶液均匀稳定的分散，将其涂在基体表面，再利用激光熔覆技术将颗粒熔覆在涂层表面，解决了涂层存在气孔的问题，并显著提高了硬度、力学性能、耐腐蚀性、高温稳定性、耐磨性等性能；本发明将等离子喷涂技术和纳米技激光熔覆技术结合，提高了涂层材料的致密性和均匀性，材料的硬度和耐磨性得到大幅度提高，还具有良好的耐紫外、耐变色能力，具有很好的应用前景。
