HEAT-INSULATING AND FLAME-RETARDANT NANO-COMPOSITE SHEET AND PREPARATION METHOD THEREOF
A heat-insulating and flame-retardant nano-composite sheet and a preparation method thereof are provided. The preparation method includes the following steps: S1: adding aerogel slurry, a flame retardant, an opacifying agent, fumed silica, high-silica glass fiber, and an additive A into a stirring tank; and stirring until uniformly mixed to acquire pasty composite slurry; S2: filling a glue tray of a roller coating device with the composite slurry acquired in step S1; and scrape-coating surfaces of a plurality of layers of a base material with the composite slurry by using discharging assemblies of the roller coating device; S3: drawing and collecting the plurality of layers of the base material acquired in step S2 at a compounding position; and pressurizing to acquire a semi-finished product; and S4: drawing the semi-finished product acquired in step S3 onto a coating line; and carrying out high-temperature drying to acquire the heat-insulating and flame-retardant nano-composite sheet.
