Preparation method of micro-nano multi-layered pore high-temperature-resistant high-strength thermal insulation material
The invention provides a preparation method of a micro-nano multi-layered pore high-temperature-resistant high-strength thermal insulation material. 10-20 parts by mass of floating beads, 10-20 partsby mass of hollow glass beads and 5-10 parts by mass of white carbon black are added into a stirring tank; a set amount of water is added, and uniform stirring is performed, so that slurry can be formed; 5-10 parts of aluminum silicate fiber and 5-10 parts of glass fiber are added while stirring is performed; the fibrous material is uniformly dispersed in the slurry; 5-10 parts of aerogel, 1-5 parts of polyvinyl alcohol and 10-15 parts of polyborosiloxane are added into the uniformly dispersed mixture; and stirring is continued, so that a cementing material, a solid material and the fiber material are mixed, so that a paste material can be obtained; and the paste is taken out of the stirring tank and laid on a water absorption substrate; and the water absorption substrate is dried in the sun or baked, so that the sheet-shaped flexible thermal insulation material can be obtained. The composite thermal insulation material provided by the invention has a multi-layered pore structure witha micro-nano size, and therefore, the high-temperature-resistant and high-strength characteristics of the composite thermal insulation material are achieved. The composite thermal insulation materialis suitable for heat insulation and energy conservation of various high-temperature devices and is also suitable for wall heat insulation.
本发明提出的是一种微纳米多级孔隙耐高温高强度保温材料制备方法。在搅拌罐中，按质量份数加入漂珠10‑20份，中空玻璃微珠10‑20份，白炭黑5‑10份，加设定量的水，搅拌均匀，成为浆状；边搅拌边加入硅酸铝纤维5‑10份，玻璃纤维5‑10份，将纤维状材料在浆料中分散均匀，在分散均匀的混合料中加入气凝胶5‑10份，聚乙烯醇1‑5份，聚硼硅氧烷10‑15份，继续搅拌，使胶结料与固态料与纤维料混合成一体，成为膏状料；将膏状料从搅拌罐中取出，摊铺在吸水基板上，晒干或烘干，成为板片状柔性保温材料。本发明提出的复合保温材料具有微纳米尺寸的多级孔隙结构。所以既耐高温又有高强度的特性。适用于各类高温设备的隔热保温节能，也适用于墙体保温。
