Aerogel-based shaped composite phase change material as well as preparation method and application thereof
The invention discloses an aerogel-based shaped composite phase change material as well as a preparation method and application thereof. The phase change material comprises aerogel and an inorganic hydrated salt phase change material loaded in the aerogel, wherein the outer surface of the aerogel is coated with a light-cured resin film. The preparation method comprises the following steps: S1, preparing an inorganic hydrated salt phase change material; s2, adding the inorganic hydrated salt phase change material prepared in the step S1 into a certain amount of aerogel, heating, uniformly stirring, and cooling to room temperature to obtain an aerogel-based phase change material; and S3, spraying organic silicon resin on the surface of the aerogel-based phase change material to obtain the aerogel-based shaped composite phase change material. The aerogel-based shape-stabilized composite phase change material prepared by the invention is high in heat storage capacity, excellent in heat stability and durability, and good in compatibility when being used in foam concrete, so that the heat exchange rate of the foam concrete is greatly reduced, the heat transfer rate is slowed down, and the heat preservation effect is ensured.
本发明公开了一种气凝胶基定形复合相变材料及其制备方法和应用。本发明包括气凝胶和负载在气凝胶中的无机水合盐相变材料，所述气凝胶的外表面包覆有光固化树脂薄膜。制备方法，包括如下步骤：S1、制备无机水合盐相变材料；S2、将步骤S1中配置好的无机水合盐相变材料加入到一定量的气凝胶中，加热，搅拌均匀，冷却降温至室温得到气凝胶基相变材料；S3、在气凝胶基相变材料表面喷涂有机硅树脂得到气凝胶基定形复合相变材料。本发明制备的气凝胶基定形复合相变材料蓄热能力强，热稳定性和耐久性优异，使用在泡沫混凝土中，相容性好，使得泡沫混凝土热交换率大幅度降低，热量传递率变缓，保证保温效果。
