有机硅聚合物复合材料陶瓷化研究进展

Organic Silicon Polymer Ceramic Chemical Research Progress

在有机硅类聚合物基体中加入粘土类无机矿物粉末填料、结构控制剂以及其它助剂制备的可瓷化聚合物基复合材料是一类新型耐火、阻燃材料。这种材料在常温下具有普通聚合物的优良性能,而遇高温燃烧时可形成坚硬的陶瓷保护层。主要介绍了有机硅聚合物高温瓷化特性及防火机理,研究了填料对复合体系耐高温性能的影响,其中包括硅灰石、云母、云母混合物体系以及其他无机填料在陶瓷化过程中的作用机理,在此基础上阐述了瓷化体系的应用领域以及其今后的发展方向。

Adding some inorganic clay mineraloid powder filler, structure control agent and other additives into organic silicon polymer matrix to produce vitrified polymer composite material, which is a new type of refractory, flame retardant materials. This kind of material has good performance of common polymer in normal temperature while in high tempera- ture it come into hard ceramic. This paper mainly introduces the high temperature vitrified characteristics and fire preven- tion mechanism of the organic silicon polymer, and introduced how the composite system influences the performance of the high temperature resistance, including the mechanism of wollastonite, mica, mica mixture system and other inorganic filler in the ceramic process. Based on the vitrified system, the paper introduced the application fields and the development direc- tion in the future.
