The invention relates to SiO2 nano composite thermal insulation paste, which is characterized in that the form of the SiO2 nano composite thermal insulation paste is a paste mixture, and the dried paste mixture becomes micro pores, nano holes and a fiber structure compound. The paste comprises the following components by weight percentage: 20 to 50 percent of SiO2 nano aerogel, 0 to 30 percent of inorganic closed-hole micro-bead material, 7 to 15 percent of expanded pearlite, 0 to 1 percent of bentonite, 2 to 6 percent of penetrating agent, 10 to 20 percent of adhesive, 3 to 6 percent of calcium silicate fiber, 0 to 5 percent of magnesium aluminum silicate fiber, 0 to 5 percent of aluminum silicate fiber, 0 to 40 percent of water, 0.1 to 2 percent of flame retardant, and 3 to 7 percent of pigment. A preparation device is a vacuum intake and stirring device.
