【摘要】：长时间处于高温环境中,金属易发生氧化腐蚀,从而丧失机械性能直至破坏,严重影响了使用效能的发挥。在金属表面涂覆耐高温涂层,因施工简便、成本较低、耐热性能好等优点而获得广泛应用,对于防止材料高温腐蚀、节约资源等具有重要的经济意义。对目前常用的耐高温涂料进行分类,包括有机耐高温涂料和无机耐高温涂料两大类,重点介绍了有机硅树脂耐高温涂料和无机耐高温涂料,并简单描述了有机-无机复合耐高温涂料的有关情况。对不同类别耐高温涂料的化学组成、物理性能和耐热机理等进行了阐述,并结合涂料的结构特点对各自优缺点进行了分析与比较。根据耐高温涂料在现代工业发展中的重要作用,介绍了国内外关于耐高温涂料的研究进展和应用情况,指出了不同类别耐高温涂料在使用过程中存在的问题。最后结合当前工业社会向信息化社会转变的时代背景以及研究耐高温涂层的技术意义,对耐高温涂料的发展趋势进行了展望。
[Abstract]:In the high temperature environment for a long time, the metal is easy to be oxidized and corroded, so the mechanical properties are lost and even destroyed, which seriously affects the exertion of the use efficiency. The coating of high temperature resistance coating on metal surface is widely used because of its advantages of simple construction, low cost and good heat resistance. It has important economic significance for preventing high temperature corrosion of materials and saving resources. This paper classifies the commonly used high temperature resistant coatings, including organic high temperature resistant coatings and inorganic high temperature resistant coatings. The emphasis is placed on the introduction of organic silicone resin high temperature resistant coatings and inorganic high temperature resistant coatings. A brief description of organic-inorganic composite high-temperature resistant coatings is given. The chemical composition, physical properties and heat resistance mechanism of different kinds of high temperature resistant coatings are expounded, and their advantages and disadvantages are analyzed and compared in combination with the structural characteristics of the coatings. According to the important role of high temperature resistant coatings in the development of modern industry, this paper introduces the research progress and application of high temperature resistant coatings at home and abroad, and points out the problems existing in the application of different kinds of high temperature resistant coatings. Finally, the development trend of high temperature resistant coatings is prospected according to the background of the transformation from industrial society to information society and the technical significance of studying high temperature resistant coatings.
