Flexible-elastic shape-stabilized temperature-controlled multifunctional phase-change material and preparation method thereof

The invention provides a flexible-elastic shape-stabilized temperature-controlled multifunctional phase-change material and a preparation method thereof. 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 i
