【摘要】 采用乳液法制备出中空酚醛树脂微球。研究了乳化剂含量、油相温度和酚醛树脂固化温度对中空微球形貌的影响。采用扫描电子显微镜和光学显微镜观察了微球的形貌和中空情况。实验结果表明,油相温度不高于80℃、乳化剂浓度介于1%-15%之间、酚醛树脂固化温度高于80℃均有利于酚醛树脂形成并维持中空的微球形状。更多还原

【Abstract】 Hollow phenolic resin microspheres were prepared from commercial phenolic resin by emulsion method. The influences of such parameters as curing temperature of phenolic resin, oil temperature and the content of surfactant to the final structure of hollow phenolic resin microspheres were studied. The surface and inner structure of phenolic resin microspheres were observed by SEM and optical microscope. The result showed that the temperature of oil less than 80℃, content of surfactant between 1%-15% and curing temperature of phenolic resin higher than 80℃ will be favored for phenolic resin to form and keep the hollow spherical shape.更多还原
