Phase change building material product with temperature control performance and preparation method of phase change building material product
The invention discloses a phase change building material product with temperature control performance and a preparation method of the phase change building material product. The preparation method comprises the following steps that before the phase change building material product with the temperature control performance is prepared and in the process of preparing a phase change microcapsule solution, a phase change microcapsule is in an environment lower than the phase change temperature, so that the phase change material is in a solid state, before the phase change building material product with the temperature control performance is prepared, the phase change microcapsules are placed in the environment with the temperature lower than the phase change temperature for a period of time so as to ensure that the phase change material is in the solid state, wherein the placement time is 5 hours to 1 month, preferably, the placement time is 20 days to 8 days, preferably, the placement time is 2 days to 12 hours; and preferably, the temperature of the environment lower than the phase change temperature is 5 DEG C or above lower than the phase change temperature. According to the preparation method, leakage of the phase change material is avoided, so that the obtained phase change building material product can adjust the indoor temperature and has higher strength.
一种具有控温性能的相变建材制品及其制备方法。所述制备方法包括相变微胶囊在制备所述具有控温性能的相变建材制品之前并且在制备为相变微胶囊溶液过程中处于低于相变温度的环境中，以使相变材料处于固态。在制备所述具有控温性能的相变建材制品之前，所述相变微胶囊在低于相变温度的环境中放置一段时间，以确保相变材料处于固态；其中放置时间为5h至一个月；优选地，所述放置时间为20天至8天；优选地，所述放置时间为2天至12h；优选地，所述低于相变温度的环境的温度低于所述相变温度5℃以上。该制备方法避免相变材料泄漏使所得相变建材制品能够调节室内温度具有更高的强度。
