摘要
以三元乙丙橡胶(EPDM)基吸油树脂作为载体,通过吸附石蜡作为相变物质,制备了高分子固-固相变储能材料。采用悬浮聚合法,探讨了EPDM基高吸油树脂的合成工艺对树脂吸附石蜡性能的影响;用扫描电子显微镜观察了吸油树脂吸附石蜡前后的微观形态变化;利用差示扫描量热仪(DSC)测定了吸附相变材料后,吸油树脂的相变温度和相变焓。结果表明:EPDM基吸油树脂对石蜡的最大吸附量可达4.9 g/g,其相变焓为124.5 J/g,具有较高的应用潜力。
The oil-absorbing resin based on EPDM rubber was used as a carrier for adsorption of phase change material such as paraffin to prepare solid-solid phase change materials （PCM）. Suspension polymeri- zation was adopted to develop a high oil-absorbing resin of EPDM series. SEM was used to observe the mor- phology before and after absorbing paraffin oil; DSC was employed to measure the phase change temperature and enthalpy after adsorbing phase change material paraffin. The results showed that the maximum adsorption capacity of paraffin on oil-absorbing resin could up to 4.9 g/g, and the phase transition enthalpy was 124.5 J/g. It can be considered as promising PCMs.
