Paraffin wax and octadecane were firstly used to prepare a phase change cold storage material with the phase transition temperature of 16.9℃ and latent heat of phase change of 124.2J/g.Then using high density polyethylene,low density polyethylene,polypropylene,and polystyrene as matrix coating materials,respectively,four kinds of paraffin composite shaped phase change energy storage materials were prepared.The effects of different support materials on phase transition temperature and latent heat of phase change were analyzed.The maximum value of paraffin blending ratio in different support materials was discussed.The results shown that high-density polyethylene was more suitable as a support material,and the optimal ratio of high-density polyethylene to paraffin was 3∶7.
