摘要:
The present disclosure provides an anisotropic lamellar inorganic fiber aerogel material and a preparation method thereof. The method includes: mixing a polymer solution, an inorganic precursor and a chloride to obtain a spinning precursor solution; blow spinning the spinning precursor solution to obtain a composite fiber aerogel; calcinating the composite fiber aerogel to obtain the anisotropic lamellar inorganic fiber aerogel material. Therefore, the method has advantages of simplicity, easy operation, low cost, high efficiency and easy industrialized production. The inorganic fiber aerogel materials prepared by the above method are composed of multi-layer stacked fibers and have an anisotropic lamellar structure, which can be cut into any desired shape, and stacked to any desired thickness. In addition, the inorganic fiber aerogel materials have good flexibility and compressibility, excellent fire resistance, good high and low temperature resistance and superior thermal insulation, which greatly expands their application field.

Provided are a core material for a vacuum insulation panel including porous aluminosilicate, and a vacuum insulation panel provided with the same. The core material for the vacuum insulation panel according to the present disclosure has superior long-term durability and improved gas adsorption ability (particularly, superior water absorption ability) while requiring a low raw material cost. The vacuum insulation panel including the core material may exhibit more improved insulation performance by minimizing a reduction in the vacuum degree without an additional getter or absorbent.
