▎ 摘　　要

NOVELTY - Cold storage material comprises carbon composite paraffin wax ice crystal nucleating microsphere. The components of the carbon composite paraffin ice crystal nucleating microspheres include paraffin and carbon materials. The carbon material accounts for 1-4.5% of the mass percentage of the carbon composite paraffin wax ice crystal nucleating microsphere, where the carbon material comprises carbon nanotube and/or graphene, preferably graphene. USE - The cold storage material is useful in preparing cold storage liquid for cold storage refrigeration device (claimed), e.g. ice cold storage air conditioner, refrigerator, cold storage, cold chain transport vehicle. ADVANTAGE - The cold storage material satisfies the cooling requirement by the cold energy released by the de-icing in the cooling system, and relieves the power supply tension of the power supply system in the peak power period, is easy to degrade, agglomeration, precipitation, phase separation and failure, affects the reliability of the cold storage refrigeration device, and improves the use reliability of the cold storage refrigeration device. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing cold storage material; and (2) a cold storage liquid comprising water and 15-25 wt.%, preferably 20 wt.% cold storage material.
