The invention discloses environment-friendly phase-change decorative spraying mortar which is prepared from the following raw materials in parts by weight: 85-95 parts of Portland cement, 24-28 partsof natural sand, 18-22 parts of phase-change material, 8-12 parts of self-extinguishing polystyrene particles, 4-6 parts of reinforcing filler, 1.5-2 parts of vinyl acetate copolymer rubber powder, 0.9-1.2 parts of assistant and 180-200 parts of tap water. The invention also discloses a preparation method of the mortar. According to the invention, the phase-change material, being a compound of paraffin and graphene oxide, is added into the mortar raw material, the phase-change material has higher thermal conductivity after being compounded with the paraffin and the graphene oxide, so that themortar is endowed with excellent phase-change performance, and the temperature control performance of the decorative mortar can be effectively improved; in addition, through auxiliary matching of thereinforcing filler and the vinyl acetate copolymer rubber powder, the mechanical strength and the fireproof performance of the decorative mortar can be improved, so that the environment-friendly phase-change decorative spraying mortar with excellent comprehensive performance is obtained, and the application prospect is wide.
本发明公开了一种环保相变装饰喷涂砂浆，包括如下重量份的原料：硅酸盐水泥85‑95份、天然砂24‑28份、相变材料18‑22份、自熄型聚苯乙烯颗粒8‑12份、增强填料4‑6份、醋酸乙烯酯共聚物胶粉1.5‑2份、助剂0.9‑1.2份、自来水180‑200份；本发明还公开了该砂浆的制备方法。本发明通过在砂浆原料中加入相变材料，相变材料为石蜡和氧化石墨烯的复合物，相变材料经过二者复合后具有更高的导热率，能够赋予砂浆优良的相变性能，可有效改善装饰砂浆的温控性能；通过增强填料和醋酸乙烯酯共聚物胶粉的辅配，能够提高装饰砂浆的力学强度和防火性能，得到一种综合性能优良的环保型相变装饰喷涂砂浆，具有广阔的应用前景。
