Preparation method of liquid paraffin/diatomite capsule phase change material and obtained material
The invention discloses a preparation method of a liquid paraffin/diatomite capsule low-temperature phase change material and the obtained material, and belongs to the technical field of functional composite materials. The preparation method comprises the following steps: mixing diatomite and liquid paraffin, dipping the mixture in a vacuum environment, filtering out the diatomite from the liquidparaffin, adding the diatomite impregnated with the liquid paraffin into an ethyl cellulose solution, carrying out stirring, filtering out diatomite, and drying the filtered solid to obtain the liquidparaffin/diatomite capsule phase change material. According to the invention, the liquid paraffin is used as a phase change energy storage material, the diatomite is used as a carrier adsorption material of the liquid paraffin, and the ethyl cellulose is used as a packaging film, so that the leakage of the liquid phase change material can be effectively prevented, and the strength difference between the phase change material and a base material is reduced. Meanwhile, the preparation cost is low, the process is simple, large-scale industrial production can be achieved, the building surface temperature can be effectively adjusted, the concrete freeze-thaw cycle problem is relieved, and the service life of a concrete structure is prolonged.
本发明公开了一种液体石蜡/硅藻土胶囊低温相变材料的制备方法及其所得材料，属于功能性复合材料技术领域。制备方法包括：将硅藻土与液体石蜡混合，置于真空环境中浸渍；将硅藻土从液体石蜡中滤出；将浸渍过液体石蜡的硅藻土加入到乙基纤维素溶液中，搅拌后滤出硅藻土；滤出的固体，烘干后，得液体石蜡/硅藻土胶囊相变材料。本发明以液体石蜡为相变储能材料，硅藻土作为液体石蜡的载体吸附材料，乙基纤维素作为封装薄膜，既能有效防止液体相变材料的泄露，又减小了相变材料和基体材料之间的强度差异。同时，制备成本低廉，过程简易，可用于大规模工业化生产，能够有效调节建构筑物表面温度，缓解混凝土冻融循环问题，延长混凝土结构使用寿命。
