Abstract

The invention belongs to the technical field of phase-change energy storage materials, relates to a beewax and polystyrene composite phase-change energy storage material, in particular relates to a beewax / polystyrene composite phase-change energy storage material and a preparation method and application thereof, and solves the technical problems in the background art. The beewax / polystyrene composite phase-change energy storage material comprises a base material and a phase-change material, the base material is polystyrene macroporous resin microspheres, and the phase-change material is beewax. The beewax / polystyrene composite phase-change energy storage material capable of being used for food is prepared by virtue of the capillary adsorption effect of the polystyrene macroporous resin microspheres; the beewax / polystyrene composite phase-change energy storage material can effectively immobilize the phase-change core material, prevent leakage, save later packaging investment and realizecigarette filter temperature control; the base material polystyrene macroporous resin microspheres of the composite phase-change material are easy to modify, and harmful components in cigarette smokecan be selectively removed while the temperature is controlled by functionally modifying the base material polystyrene macroporous resin microspheres.

Description

Technical field[0001]The invention relates to the technical field of phase change energy storage materials, and relates to beeswax and polystyrene composite phase change energy storage materials, in particular to a beeswax / polystyrene composite phase change energy storage material and a preparation method and application thereof.Background technique[0002]Cigarette filters are not only a bridge between smokers and mainstream smoke, but also can effectively intercept a variety of harmful components in mainstream smoke. Studies have shown that inertial collision, diffusion deposition and direct retention are the main methods for filter to remove smoke particles. The filtering effect of the filter is not only related to its constituent materials and structural design, but also affected by the temperature during the combustion process. During the smoking process, the smoke temperature at the filter end of the cigarettes continues to rise, reaching as high as 70°C-80°C in the 2~3 puffs be...
