Aerogel modified composite magnesium silicate thermal insulation material as well as preparation method and application thereof
The invention provides an aerogel modified composite magnesium silicate thermal insulation material as well as a preparation method and application thereof, and particularly relates to the technical field of thermal insulation materials. The slurry of the thermal insulation material comprises mineral fibers, aerogel slurry, wood fibers, an adhesive, a penetrant, a coupling agent, magnesium hydroxide and water. Wherein the mineral fibers comprise brucite mineral fibers, wollastonite mineral fibers and aluminum silicate fibers. According to the prepared thermal insulation material structure, sufficient aerogel powder is embedded in the composite magnesium silicate thermal insulation material to fill the space of the composite magnesium silicate thermal insulation material to form a fine and effective air cavity, the heat conductivity coefficient is only 0.030 W/(mK)-0.036 W/(mK), the convection efficiency of air in the air cavity is greatly weakened, and the good thermal insulation effect is achieved.
本发明提供一种气凝胶改性复合硅酸镁保温材料及其制备方法和应用，具体涉及保温材料技术领域。该保温材料的浆料包括矿物纤维、气凝胶浆料、木质纤维、粘合剂、渗透剂、偶联剂、氢氧化镁和水；其中，所述矿物纤维包括水镁石矿物纤维、硅灰石矿物纤维和硅酸铝纤维。制成后的保温材料结构中有充足的气凝胶粉“镶嵌”在复合硅酸镁保温材料之中，充盈其空间，形成细密有效的“气腔”，导热系数仅有0.030W/(m∙K)‑0.036W/(m∙K)，空气在其中对流效率大大减弱，具有良好的隔热效果。
