Nano-ceramic composite thermal insulation material and preparation method thereof
The invention discloses a nano ceramic composite thermal insulation material. The nano ceramic composite thermal insulation material comprises, by weight, 25 to 40 parts of waste cellucotton, 10 to 35parts of nano zirconium oxide, 20 to 40 parts of nano yttrium oxide, 30 to 50 parts of sepiolite wool, 10 to 15 parts of a quick penetrating agent T, 20 to 30 parts of attapulgite hydrosol, 10 to 20parts of silicon dioxide hydrosol, 80 to 110 parts of vitrified micro bubbles, 5 to 10 parts of floating beads, 10 to 20 parts of expanded perlite and 380 to 620 parts of water. According to the invention, the waste cellucotton is recycled to prepare the composite thermal insulation material, the surface of the obtained composite material is carbon-bonded and vitrified in high-temperature burningflame and does not burn off or fall off, and the composite material serving as a protective layer has the effects of no cracking, no crack and no sinking in thermal expansion and contraction and no sagging under the action of vibration and gravity; the nano zirconium oxide and the nano yttrium oxide are added, gaps of the cellucotton can be filled with the ceramic micro-particles, and the impact resistance of the composite material is improved; the sepiolite wool is added and can be intertwined with a fiber surface, so that the tensile strength and the impact resistance of the composite material are improved.
本发明公开了一种纳米陶瓷复合绝热材料，包括以下重量份的组分：废旧纤维棉25‑40份、纳米氧化锆10‑35份、纳米氧化钇20‑40份、海泡石绒30‑50份、快速渗透剂T 10‑15份、凹凸棒土水溶胶20‑30份、二氧化硅水溶胶10‑20份、玻化微珠80‑110份、漂珠5‑10份、膨化珍珠岩10‑20份、水380‑620份。本发明将废旧纤维棉回收利用制备复合绝热材料，所得复合材料在高温烈焰中表面碳结玻璃化，不会烧散脱落，作为保护层具有热胀冷缩不开裂、无裂缝，在震动、重力作用下不下沉、不下垂的效果；本发明添加纳米氧化锆和纳米氧化钇，陶瓷微颗粒可填充在纤维棉的缝隙中，增加了复合材料的抗冲击性能；本发明添加海泡石绒，可与纤维面互相缠结，提升复合材料的拉伸强度和抗冲击性能。
