Ultra-light inorganic efficient thermal insulation material and preparation method thereof
The invention discloses an ultra-light inorganic efficient thermal insulation material and a preparation method thereof. The ultra-light inorganic high-efficiency thermal insulation material disclosed by the invention is mainly prepared from the following components in parts by weight through a pressurization foaming-pressure relief foaming process: 28 to 37 parts of light calcined magnesia, 18 to 26 parts of magnesium sulfate heptahydrate, 0.8 to 1.5 parts of a compound foaming agent, 0.08 to 0.12 part of a compound foam stabilizer, 0.1 to 0.3 part of a water reducing agent and 45 to 58 parts of water. The inorganic efficient thermal insulation material is prepared through a pressurization foaming-pressure relief foaming technology, under the pressurization condition, a large number of stable and uniform bubbles are introduced into the inorganic thermal insulation material, then a large number of uniform and stable pressurization bubbles are evenly mixed with cement slurry to obtain foaming slurry, in the pressure relief process, the bubbles in the pressurization foaming slurry are evenly expanded, and the foaming effect is good. The volume weight of the prepared ultra-light inorganic efficient thermal insulation material can reach 41-60 kg/m < 3 >, the strength is larger than or equal to 10 kPa, and the heat conductivity coefficient can reach 0.029-0.035 W/(m.k).
