The invention discloses a phase change temperature control material and a preparation method thereof. The phase change temperature control material of the present invention comprises the following components in parts by mass: main resin: 70-100 parts; phase-change metal oxide powder: 1-10 parts; organic phase-change material: 5-20 parts; thermally conductive powder: 8-25 parts; dispersant: 1-5 parts; compatibilizer: 0-5 parts; antioxidant: 0.1-1 part. The preparation method of the phase-change temperature-controlling material of the present invention comprises the following steps: mixing the components uniformly, adding them to a twin-screw extruder, and extruding and granulating. The phase change temperature control material of the invention has large latent heat of phase change, high thermal conductivity, excellent comprehensive mechanical properties, and simple preparation method, and can be widely used in the production and processing of battery casings, home appliance casings, industrial equipment casings and other products. |
