The preparation method comprises adding MMA and AIBN in a water bath of 80 DEG C, stirring for 25 min, then adding molten binary aliphatic acid, intensely stirring for 5 min; pouring the mixture into a die, sealing the die, putting the die in a water bath of 60 DEG C for 2 hours, and then putting the die in a water bath of 90 DEG C for 1 hour to obtain the binary aliphatic acid / PMMA shape-stabilized phase change material. The shape-stabilized phase change material has an appropriate phase change temperature and large phase change latent heat, is good in heat stability, and has good application prospects.

The invention relates to a corrugated box processing method. The corrugated box processing method comprises the following steps that S1, corrugated board is machined; S2, corrugated board is subjectedto die cutting, especially, the corrugated board is cut and creased by using a cutting creasing machine so that the corrugated board can be folded to form a box body; S3, the corrugated board is folded, especially, the corrugated board is folded to form a corrugated box, the corrugated box is put between a bottom plate and the inner supporting plate mounted on a top plate, and the side edge of the corrugated box is flattened through a leveling mechanism; S4, the corrugated box is bound, especially, the corrugated box in the step S3 is conveyed to a proper position, and the corrugated box is bound by a box nailing machine; S5, the corrugated box is detected; and S6, the corrugated box is stacked up. According to the corrugated box processing method, the problems that a folding position ofthe corrugated box deviates when the corrugated box is bound, so that the corrugated box binding is inclined, a binding position of the corrugated box can be warped when the corrugated paper box is bound, multi-person cooperation operation is needed, the labor amount of workers is increased, and the processing efficiency of the corrugated box is low are solved.
