| Abstract: | The thermal insulating material is prepared through the sol-gel process, using the cheap water glass as the main raw material and blending with other components such as alumina silicate fi bre, silica fume, titania powder and ? oating pearls. From the result of material performance test we know the nano-aperture silicon thermal insulating material has low heat conductivity, high compressive strength, low line contraction ratio and high waterproof performance. The main factors such as the pH value of solution and the quantities of silica fume and floating pearls which affect the procedure of material are discussed. |
