Hydrated calcium silicate-based composite thermal insulation material and preparation method thereof
The invention discloses a hydrated calcium silicate-based composite thermal insulation material and a preparation method thereof. The material is obtained by adding a uniform suspension of hydrated calcium silicate into an aqueous solution of an organic cross-linking agent, stirring, releasing ions, cross-linking and freeze-drying, and has lower density and lower heat conductivity coefficient. According to the invention, the calcium ion release ability of the hydrated calcium silicate in an aqueous solution and the ionic crosslinking ability of the organic crosslinking agent are combined to form an organic-inorganic dual network in the solution. According to the heat preservation and insulation material, the hydrated calcium silicate porous material which is not concerned in the field is applied to the field of building energy conservation, the potential of the hydrated calcium silicate porous material serving as the heat preservation and insulation material is fully exerted, and the heat preservation and insulation material is beneficial to reducing building operation energy consumption, reducing carbon emission and reducing the greenhouse effect.
本发明公开了一种水化硅酸钙基复合保温隔热材料及其制备方法。该材料由水化硅酸钙的均匀悬浮液加入倒有机交联剂的水溶液中，经搅拌、离子释放、交联和冷冻干燥获得，具有较低的密度和较低的导热系数。本发明结合水化硅酸钙在水溶液中的钙离子释放能力和有机交联剂的离子交联能力，形成了溶液中的有机‑无机双网络。本发明的保温隔热材料将该领域中尚未被大量关注的水化硅酸钙多孔材料应用于建筑节能领域，充分发挥了其作为保温隔热材料的潜力，这有助于减少建筑运行能耗，缩减碳排放，降低温室效应。
