Multi-layer phase-change annual energy-saving material and preparation method thereof
The invention discloses a multi-layer phase-change annual energy-saving material and a preparation method thereof. The multi-layer phase-change annual energy-saving material comprises a carbonized base material layer, a radiant energy collecting layer and a phase-change radiation switch layer which are sequentially arranged from inside to outside, the carbonized base material layer is made of carbonized material slurry; the phase change radiation switch layer is prepared from the following raw materials in parts by mass: 0.5 to 25 parts of modified nano vanadium dioxide, 20 to 60 parts of polymer base material, 130 to 200 parts of acetone and 0.2 to 15 parts of zirconium dioxide. In the multi-layer phase-change year-round energy-saving material, the phase-change radiation switch realizes on-off conversion of transmission and reflection at different temperatures through spectrum conversion of the phase-change material, has a good radiation refrigeration function in summer, has solar reflectivity and atmospheric window emissivity exceeding 90%, and realizes solar transmittance exceeding 70% in winter. Solar heat is absorbed through the radiant energy collecting layer to achieve heat absorption of the building, and annual energy saving is achieved.
本发明公开一种多层相变全年节能材料及其制备方法，包括从里向外依次设置的碳化基材层、辐射能收集层和相变辐射开关层；碳化基材层由碳化材料浆体制成；按质量份数计，相变辐射开关层的原料包括改性纳米二氧化钒0.5～25份、聚合物基材20～60份、丙酮130～200份以及二氧化锆0.2～15份。本发明的多层相变全年节能材料中，相变辐射开关通过相变材料的光谱转变实现不同温度下的透过与反射的开关转变，在夏季具有良好的辐射制冷功能，具有超过90％的太阳反射率和大气窗口发射率，在冬季实现太阳透过率超过70％，通过辐射能收集层吸收太阳热量实现建筑汲热，实现全年节能。
