Embodiment Construction
[0020] The following will combine figure 1 , figure 2 The present invention is further described.
[0021] A nano-microporous heat insulation board, which includes silicon dioxide with a particle size range of 5-20nm, silicon carbide with a particle size range of 2-12um, zirconium silicate with a particle size range of 2-15um and a diameter range of 5- 15um high-silica glass fiber, the length of high-silica glass fiber is 5-15mm, and the silicon carbide material can be replaced by other metal oxides such as titanium dioxide and aluminum oxide.
[0022] A method for manufacturing a nano-microporous heat insulation board, comprising the steps of:
[0023] Weigh silicon dioxide, silicon carbide, zirconium silicate, and high-silica glass fiber raw materials by weight;
[0024] Fully mix the prepared raw materials in a high-speed mixer;
[0025] The mixed material is dry-pressed in a special mold of a hydraulic press.
[0026] Wherein the weight ratio range of silicon dioxide...
