摘要(中) 本論文利用懸浮聚合法製備電鍍共沉積用之潤滑油微膠囊，將單體、
交聯劑、潤滑油和起始劑混合，加入含有穩定劑PVA 的水溶液中，以
乳化均質機攪拌均勻後進行懸浮聚合反應，進而製備潤滑油微膠囊材料。
本實驗使用的單體為甲基丙烯酸甲酯(MMA)、苯乙烯(St)，交聯劑為二甲基
丙烯酸乙二醇酯(EGDMA)和起始劑偶氮二異丁腈(AIBN)。
本研究探討穩定劑濃度、單體比例、起始劑添加量、交聯劑濃度、
均質機轉速、反應時間和潤滑油的添加量等不同條件對微膠囊材料的整
體轉化率、潤滑油含量、潤滑油產率、高分子產率、包覆效率及外觀的
影響，並利用熱重損失分析儀(TGA)、傅立葉轉換紅外線光譜儀(FTIR)、
掃描式電子顯微鏡(SEM)和動態光散射儀(DLS)進行分析。
從本研究中可得知，當穩定劑PVA 濃度為0.1wt%時有最佳微膠囊
外觀，St 的單體比例為50%以上時較適合作為微膠囊殼層，起始劑添加
量和交聯劑濃度的上升有助於提升整體轉化率和高分子產率，反應時間為
6 和8 小時有較佳的潤滑油含量和產率。
本研究可製備出潤滑油含量為63.4%，粒徑範圍約為150~350nm，
以及整體轉化率為71.2%之潤滑油微膠囊材料。
摘要(英) Microcapsulation of lubricating oil for electrolytic co-deposition has been
developed by suspension polymerization. Monomers, cross-linking agent,
lubricating oil, and initiator were mixed and then added to the water phase
including stabilizer, PVA. After that, the solution was homogenized and
proceeded to suspension polymerization at 70oC. Methyl methacrylate (MMA)
and styrene (St) were used as the monomers. Ethylene Glycol Dimethacrylate
(EGDMA) was used as cross-linking agent. Azobisisobutyronitrile (AIBN) was
used as initiator.
In this study, different parameters, the concentrations of stabilizer, initiator,
cross-linking agent, and lubricating oil, homogenized speed, reaction time, and
addition of lubricating oil were discussed. Thermo gravimetric Analysis (TGA),
Scanning Electron Microscope (SEM) Fourier-Transform Infrared Spectrometer
(FTIR), Dynamic light scattering (DLS) were used to determine the
characterization of the microcapsules.
The results showed that the morphology of microcapsules could be
improved by adding 0.1wt% of stabilizer. The weight fraction of St in monomers
more than or equal to 50% was more suitable to be the shell materials. As the
amount of initiator and cross-linking agent increased, the total conversion and
polymer yield would increase. When reaction time was 6 or 8 hours, there are
better lubricating oil content and yield.
The best results of microcapsules showed that the lubricating oil content is
63.4%, the range of particle size is from 150 to 350nm, and the total conversion is 71.2%.
