使用光学显微镜对固化过程中,钛酸盐晶须与氧化石墨烯复配后的复合材料在生物基树脂中的流动性进行研究。钛酸盐晶须的质量分数为1%,晶须的长度为·5~10μm,厚度为100nm,氧化石墨烯的质量分数为0.1%,采用325目的石墨粉,通过改进的hummers法制备而成。使用腰果酚活性稀释剂与石油基环氧树脂E51进行复配(未添加腰果酚基固化剂,生物基树脂含量为30%),刮涂50μm的涂层,每隔15分钟拍摄一次,观察钛酸盐晶须在涂层固化过程中的流动性,分散性以及沉降程度。
The fluidity of titanate whisker and graphene oxide composites in biobased resin was studied by optical microscope. The mass fraction of titanate whisker is 1%, the length of whisker is ·5~10μm, the thickness is 100nm, the mass fraction of graphene oxide is 0.1%, and 325 mesh graphite powder is used to prepare it by the improved hummers method. Cashew phenol active diluent was combined with petroleum-based epoxy resin E51 (no cashew phenol curing agent was added, the content of bio-based resin was 30%), and 50μm coating was scraped and photographed every 15 minutes to observe the fluidity, dispersion and settlement degree of titanate whisker during the coating curing process.
