A phase change microcapsule with temperature control, electromagnetic shielding and flame-retardant smoke suppression function and PVC decorative strip
Phase change microcapsules were prepared by coating phase change alkanes with iron oxide as the shell material and then composited with PVC. This solved the shielding and combustion problems of PVC decorative strips under electromagnetic radiation and high load power, and achieved the effects of efficient temperature control, electromagnetic shielding and flame retardancy and smoke suppression.

Abstract
The application relates to the field of high polymer materials, and discloses a phase change microcapsule with temperature control, electromagnetic shielding and flame-retardant smoke suppression functions and a PVC decorative strip. The phase change microcapsule is synthesized by taking ferroferric oxide as a shell material and coating phase change alkane with a phase change function. The ferroferric oxide not only has wave absorption and can play an electromagnetic shielding role, but also has flame-retardant smoke suppression functions, and compared with conventional high polymer shell materials, the ferroferric oxide has better thermal conductivity, so that the response speed of the phase change microcapsule to the ambient temperature is faster. Therefore, the phase change microcapsule is used as a filler to be compounded with PVC, and the obtained PVC decorative strip has high-efficiency temperature control, electromagnetic shielding and flame-retardant smoke suppression functions.
