Embodiment 1
[0020] Add the industrial TiO of water glass glue quality 10% in the waterglass glue through ion exchange 2 powder, 30% tap water, and chemical dispersant for brucite fiber with TiO 2 Sodium dodecylbenzenesulfonate with a total mass of 15%, ball milled for 1.5 hours, poured into a mixer, added brucite fiber with a length of less than 5mm in a mass of 6% of water glass glue, beaten and stirred for half an hour, injected into the metal Mold, heated at 40°C until cured. Then wash the cured body with distilled water until it is neutral, soak it in absolute ethanol for 48 hours, then soak it in a commercially available silicone solution for 10 minutes, and finally dry it under normal pressure at 55°C to obtain the product. The product has no volume shrinkage, good hydrophobicity, and a density of 0.21g / cm 3 , The thermal conductivity is 0.012W / M.K.
Embodiment 2
[0022] In the commercially available industrial silica sol liquid of solid content 25%, add the industrial Fe of silica sol liquid quality 5% 3 o 4 powder, 10% tap water, and brucite fiber and Fe 3 o 4 20% of the total mass of di-isooctyl sodium maleate sulfonate, ball milled for 2 hours, poured into the mixer, adding brucite fiber with a length of 9% of the mass of the silica sol solution and less than 5mm in length, beating and stirring for 1 hour, Pour into the mold and heat at 50°C until solidified. Then it was washed with distilled water to neutrality, then soaked in absolute ethanol for 36 hours, then impregnated with organic silicon for 20 minutes, and finally dried under normal pressure at 65°C to obtain the product. The product has no volume shrinkage, good hydrophobicity, and a density of 0.43g / cm 3 , The thermal conductivity is 0.025W / M.K.
Embodiment 3
[0024] Add the industrial TiO of water glass glue quality 15% in the waterglass glue through ion exchange 2 Powder, 20% tap water, and brucite fiber and TiO 2 Sodium lauryl sulfate with a mass sum of 25%, ball milled for 1 hour, poured into a mixer, added brucite fiber with a length of less than 5mm in a water glass glue with a mass of 7.5%, beaten and stirred for 1 hour, injected into a mould, at 35 °C until solidified. Then wash the cured body with distilled water until it becomes neutral, then soak it in absolute ethanol for 48 hours, then soak it with a commercially available silicone solution for 30 minutes, and finally dry it under normal pressure at 60°C to obtain the product. The product has no volume shrinkage, good hydrophobicity, and a density of 0.40g / cm 3 , The thermal conductivity is 0.020W / M.K.
