Embodiment 1
[0028] 1) Using silicon oxide nano-powder, high-silica fiber and potassium titanate whisker as the main raw materials, it is uniformly dispersed through dry mechanical fusion; the dispersed materials are put into a mold, molded by a press, and obtained after demoulding. Rigid nano insulation.
[0029] 2) Make the pressed density 0.5g / cm 3 The 0.5mm rigid insulation material is used as the core material, and the 0.5mm quartz fiber cloth (fiber felt) is used as the flexible reinforced panel; the design idea of the sandwich structure is adopted, and the materials are laid in the order of "panel-core-panel" ;
[0030] 3) Select the quartz fiber thread as the suture line, determine the suture spacing of grid pattern to be 100mm, and use the suture tool to suture and cover the paved materials up and down, and finally obtain the suture-type flexible nano-insulation material.
Embodiment 2
[0032] 1) With silica nano-powder, quartz fiber and titanium dioxide as the main raw materials, it is uniformly dispersed through dry mechanical fusion; the dispersed materials are put into a mold, molded by a press, and a rigid nano-insulation material is obtained after the mold is removed.
[0033] 2) Make the pressed density 0.1g / cm 3 The 20mm rigid insulation material is used as the core material, and the 1mm high silica fiber cloth is used as the flexible reinforced panel; the design idea of the sandwich structure is adopted, and the materials are laid in the order of "panel-core-panel";
[0034] 3) Select the quartz fiber thread as the suture line, determine the grid suture spacing of 10mm, and use the suture tool to suture the laid material up and down through the coating, and finally obtain the suture-type flexible nano-insulation material.
Embodiment 3
[0036] 1) With silica nano-powder, aluminum silicate fiber and titanium dioxide as the main raw materials, it is uniformly dispersed through dry mechanical fusion; the dispersed materials are put into a mold, molded by a press, and rigid nano-insulation is obtained after the mold is removed Material.
[0037] 2) Make the pressed density 0.1g / cm 3 The 20mm rigid insulation material is used as the core material, and the 2mm high silica fiber cloth is used as the flexible reinforced panel; the design idea of the sandwich structure is adopted, and the materials are laid in the order of "panel-core-panel";
[0038] 3) Select the quartz fiber thread as the suture line, determine the grid suture spacing of 10mm, and use the suture tool to suture the laid material up and down through the coating, and finally obtain the suture-type flexible nano-insulation material.
