Phase-change thermal insulation material, preparation method thereof and application of phase-change thermal insulation material in thermal rectification
The invention relates to the technical field of building materials, in particular to a phase-change thermal insulation material, a preparation method thereof and application of the phase-change thermal insulation material in thermal rectification. The preparation method of the phase change thermal insulation material is characterized by comprising the following steps: S1, mixing silicon dioxide aerogel powder with water to obtain a flocculent mixture; then carrying out compression molding on the flocculent mixture, and drying and hardening to obtain a silicon dioxide aerogel standard block; s2, enabling the silicon dioxide aerogel standard block to adsorb molten alkane of C15 to C25 and/or fatty acid of C15 to C25; wherein the mass ratio of the aerogel standard blocks before and after adsorption is controlled to be (1.5-2): 1. According to the phase-change thermal insulation material and the preparation method and application thereof, the thermal rectification performance is combined into a thermal insulation layer of a building outer wall, and the phase-change thermal insulation material has good stability and reliability and can be produced in batches.
本发明涉及建筑材料技术领域，尤其涉及一种相变保温材料及其制备方法与其在热整流方面的应用。所述相变保温材料的制备方法，其特征在于，包括：S1：将二氧化硅气凝胶粉末与水混合，得到絮状混合物；而后将所述絮状混合物进行压制成型，干燥硬化后得到二氧化硅气凝胶标准块；S2：将所述二氧化硅气凝胶标准块吸附熔融的C15～C25的烷烃和/或C15～C25的脂肪酸；其中，控制所述气凝胶标准块吸附前后的质量比为(1.5～2)：1。本发明提供的一种相变保温材料、及其制备方法与应用，将热整流性能结合到建筑外墙的保温层中，并具备良好的稳定性和可靠性，可实现批量生产。
