Refractory belt corundum mullite silicon carbide plastic refractory for power plant boiler and preparation method of refractory belt corundum mullite silicon carbide plastic refractory
The invention relates to the technical field of plastic refractory, in particular to a refractory belt corundum mullite silicon carbide plastic refractory for a power plant boiler and a preparation method of the refractory belt corundum mullite silicon carbide plastic refractory. The refractory belt corundum mullite silicon carbide plastic refractory of the invention comprises main material powder, auxiliary material powder, coating powder and a binding agent; the main material powder comprises one or more components selected from corundum mullite, silicon carbide and high-aluminum aggregate;the auxiliary material powder comprises one or more components selected from boron carbide, brown fused alumina and graphite; the coating powder is graphene, and the binding agent is kaolin ore. According to the refractory belt corundum mullite silicon carbide plastic refractory for the power plant boiler and the preparation method of the refractory belt corundum mullite silicon carbide plastic refractory of the invention, the auxiliary material powder is added to replace a traditional oxide material, so that the material has the performance of not wetting molten coal ash at high temperature,and the phenomenon of erosion and melting loss of the conventional material due to liquid phase appearing at high temperature, the wetting of the conventional material with molten coal ash and permeation of the conventional material with molten coal ash is avoided.
本发明涉及可塑料技术领域，具体是一种电厂锅炉卫燃带刚玉莫来石碳化硅可塑料及其制备方法。包括主料粉、辅料粉、涂粉及结合剂，所述主料粉包括刚玉莫来石、碳化硅、高铝骨料中的一种或几种，所述辅料粉包括碳化硼、棕刚玉、石墨中的一种或几种，所述涂粉为石墨烯，所述结合剂为高岭土矿。本发明通过采用添加辅料粉来代替传统氧化物材料，从而使材料具有高温不与熔融煤灰润湿的性能，避免了常规材料由于高温下出现液相并与熔融煤灰润湿、渗透其引起的侵蚀熔损的现象。
