目的 制备MPCMs/环氧树脂复合材料，研究石蜡相变微胶囊(MPCMs)对环氧树脂导热调温性能的影响。方法 采用共混法制备MPCMs/环氧树脂复合材料，对共混改性的复合材料进行导热、储热、调温及热稳定性能表征。结果 MPCMs/环氧树脂复合材料导热系数增大，为原来的4.91倍以上，相变潜热特性与MPCMs的质量分数成正比，有自我调节温度能力。 结论 MPCMs/环氧树脂复合材料提高了环氧树脂的导热性能，保留了MPCMs的相变储热调温性能，热稳定性良好。

The work aims to prepare MPCMs/epoxy resin composite and investigate the effect of phase change microcapsules (MPCMs) on thermal conductivity and temperature regulation of epoxy resin. MPCMs/Epoxy resin composites were prepared by blending method, and the modified MPCMs/ epoxy resin composites were characterized by heat conduction, heat storage, temperature regulation and thermal stability. The thermal conductivity of MPCMs/Epoxy resin composite increased by more than 4.91 times compared with the original. The latent heat characteristic of phase change was proportional to the mass fraction of MPCMs, and had the ability of regulating temperature. MPCMs/epoxy resin composite improves the thermal conductivity of epoxy resin, maintains the phase change heat storage and temperature regulation performance of MPCMs, and has good thermal stability.
