The flexible-elastic shape-stabilized temperature-controlled multifunctional phase-change material comprises the following raw materials in percentage by mass: 75-85% of paraffin alkane phase-change material, 12-20% of olefin block copolymer, 2-8% of hydrogenated styrene butadiene block copolymer and 0.5-1% of cross-linking agent. The material is excellent in soft and elastic shaping effect, high in energy storage density and good in temperature control effect, and the phase change temperature within 18-65 DEG C is adjustable. The invention also provides a preparation method of the flexible-elastic shape-stabilized temperature-controlledmultifunctional phase-change material. The preparation method is wide in raw material source, low in cost, simple, environmentally friendly, safe and non-toxic, and the problems that in the prior art,the preparation process is complex, mass production is difficult, and the obtained material is limited in performance are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of multifunctional phase change materials, and in particular relates to a soft-elastic shape setting temperature control multifunctional phase change material and a preparation method thereof. Background technique [0002] Phase change materials need to be packaged when used, and the emergence of solid-liquid (shape-fixed) phase change materials with stable shape has brought development opportunities for the field of phase change energy storage. At present, the shape-setting phase change materials are mainly phase change microcapsules with complicated preparation process and porous matrix composite phase change materials which are difficult to mass produce. There is an urgent need for a low-cost, environmentally friendly and convenient preparation method for shape-setting phase change materials. The performance of composite materials obtained by melt blending phase change materials and a single thermoplasti...
