Preparation method of paraffin-cement adhesion type phase-change material and material obtained thereof
The invention belongs to the technical field of phase-change material preparation, and particularly relates to a paraffin-cement adhesion type phase-change material preparation method and a material obtained thereof. The preparation method comprises the following steps that 1) mixing solid paraffin and liquid paraffin according to a certain proportion and then put into a sealing bag, putting the sealing bag into hot water, melting to obtain a solid-liquid paraffin mixture with the phase transition temperature of 20-25 DEG C; and 2) mixing the cement and the standard sand according to a certain proportion, adding the molten solid-liquid paraffin mixture and warm water with the same temperature according to a certain proportion, and continuously stirring while adding until no obvious liquid is separated out. The solid-liquid paraffin mixture with the phase-change temperature of 20-25 DEG C is prepared by mixing the solid paraffin and the liquid paraffin, the solid-liquid paraffin mixture is matched with the most comfortable water temperature of a human body, the composite phase-change material suitable for being used in a heat preservation device of water treatment equipment in a severe cold area can be prepared, and the solid-liquid paraffin mixture has the advantages of being low in manufacturing cost and good in energy storage durability.
本发明属于相变材料制备技术领域，具体涉及一种石蜡‑水泥附着型相变材料的制备方法及其所得材料，制备方法包括如下步骤：1)将固体石蜡和液体石蜡按一定比例混合后装入密封袋中，密封袋放入热水中，融化得到相变温度为20‑25℃的固‑液石蜡混合物；2)先将水泥与标准砂按一定比例混合，再按一定比例加入已经融化的固‑液石蜡混合物和与其同等温度的温水，一边加入一边不断搅拌，直至看不见明显的液体析出。本发明使用将固态石蜡与液态石蜡混合的办法制得相变温度在20‑25℃的固‑液石蜡混合物，与人体最舒适的水温度相匹配，能够制备适合严寒地区水处理设备保温装置中所用的复合相变材料，具有制作成本低和储能耐久性好的优点。
