Multilayer phase-change energy-saving wallboard and preparation method thereof
The invention discloses a multilayer phase-change energy-saving wallboard which is prepared from the following components in percentage by weight: mixed powder particles, chemical mixed liquid, phase-change material, additives and an organic solvent, wherein the chemical mixed liquid accounts for 5-15%, the phase-change material accounts for 2-8%, the mixed powder particles account for 25-42%, the additives account for 5-10%, and the organic solvent accounts for 10-25%. The phase-change material is added into the raw materials of the wallboard so that the overall expansion contractibility of the wall body is small, the phenomenon of supercooling or overheating is few, the heat conductivity coefficient is large, the density is large, the specific heat capacity is large, and the wallboard is overall non-toxic, non-corrosive, low in cost and convenient to manufacture.
本发明公开了一种多层相变节能墙板，由混合粉粒、化工混合液、相变材料、添加剂和有机溶剂制成，其中所述化工混合液占比设为5‑15％，所述相变材料占比设为2‑8％，所述混合粉粒占比设为25‑42％，所述添加剂的占比设为5‑10％，所述有机溶剂的占比设为10‑25％。本发明的墙板的原料中加入相变材料，使得墙体整体的膨胀收缩性小、过冷或过热现象少，并且导热系数大，密度大，比热容大，整体无毒，无腐蚀性，成本低，制造方便。
