Nano-porous thermal insulation material
The invention discloses a nano-porous thermal insulation material, and relates to the technical field of thermal insulation materials. The thermal insulation material comprises the following components of: 30-40 parts of nano-silica powder; 20-30 parts of nano-cellulose powder; 50-60 parts of an organic solvent; 5-8 parts of an opacifying agent; 1-1.4 parts of a chemical dispersant; and 3-5 partsof a catalyst. According to the nano porous thermal insulation material of the invention, the Nano fiber powder and the nano silicondioxide powder are compounded; and therefore, a preparation processhas low requirements on equipment, the requirement of a traditional preparation method for supercritical drying equipment is avoided, and production cost is remarkably reduced. The obtained nano-porous thermal insulation material has low thermal conductivity at the high temperature, is high in thermal insulation effect and large in specific surface area, can resist the temperature of 1,200 DEG C and is excellent in various resistance properties.
